The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects. Collected 3D data is useful for a wide variety of applications.
These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality.
The purpose of a 3D scanner is usually to create a 3D model. This 3D model consists of a polygon mesh or point cloud of geometric samples on the surface of the subject.
These points can then be used to extrapolate the shape of the subject a process called reconstruction. If colour information is collected at each point, then the colours or textures on the surface of the subject can also be determined.
Like most cameras, they have a cone-like field of view , and like cameras, they can only collect information about surfaces that are not obscured. While a camera collects colour information about surfaces within its field of view , a 3D scanner collects distance information about surfaces within its field of view. The “picture” produced by a 3D scanner describes the distance to a surface at each point in the picture.
This allows the three dimensional position of each point in the picture to be identified. In some situations, a single scan will not produce a complete model of the subject. Multiple scans, from different directions are usually helpful to obtain information about all sides of the subject. These scans have to be brought into a common reference system , a process that is usually called alignment or registration , and then merged to create a complete 3D model.
This whole process, going from the single range map to the whole model, is usually known as the 3D scanning pipeline. There are a variety of technologies for digitally acquiring the shape of a 3D object. The techniques work with most or all sensor types including optical, acoustic, laser scanning, [13] radar, thermal, [14] and seismic. Non-contact solutions can be further divided into two main categories, active and passive. There are a variety of technologies that fall under each of these categories.
Contact 3D scanners work by physically probing touching the part and recording the position of the sensor as the probe moves around the part. Both modern CMMs and Articulated Arms can also be fitted with non-contact laser scanners instead of touch probes. Active scanners emit some kind of radiation or light and detect its reflection or radiation passing through object in order to probe an object or environment.
Possible types of emissions used include light, ultrasound or x-ray. The time-of-flight 3D laser scanner is an active scanner that uses laser light to probe the subject. At the heart of this type of scanner is a time-of-flight laser range finder. The laser range finder finds the distance of a surface by timing the round-trip time of a pulse of light.
A laser is used to emit a pulse of light and the amount of time before the reflected light is seen by a detector is measured. The laser range finder only detects the distance of one point in its direction of view. Thus, the scanner scans its entire field of view one point at a time by changing the range finder’s direction of view to scan different points.
The view direction of the laser range finder can be changed either by rotating the range finder itself, or by using a system of rotating mirrors. The latter method is commonly used because mirrors are much lighter and can thus be rotated much faster and with greater accuracy. Time-of-flight devices are also available in a 2D configuration. This is referred to as a time-of-flight camera. Triangulation based 3D laser scanners are also active scanners that use laser light to probe the environment.
With respect to time-of-flight 3D laser scanner the triangulation laser shines a laser on the subject and exploits a camera to look for the location of the laser dot. Depending on how far away the laser strikes a surface, the laser dot appears at different places in the camera’s field of view. This technique is called triangulation because the laser dot, the camera and the laser emitter form a triangle.
The length of one side of the triangle, the distance between the camera and the laser emitter is known. The angle of the laser emitter corner is also known. The angle of the camera corner can be determined by looking at the location of the laser dot in the camera’s field of view. These three pieces of information fully determine the shape and size of the triangle and give the location of the laser dot corner of the triangle.
The National Research Council of Canada was among the first institutes to develop the triangulation based laser scanning technology in Time-of-flight and triangulation range finders each have strengths and weaknesses that make them suitable for different situations.
The advantage of time-of-flight range finders is that they are capable of operating over very long distances, on the order of kilometres. These scanners are thus suitable for scanning large structures like buildings or geographic features. The disadvantage of time-of-flight range finders is their accuracy. Due to the high speed of light, timing the round-trip time is difficult and the accuracy of the distance measurement is relatively low, on the order of millimetres.
Triangulation range finders are exactly the opposite. They have a limited range of some meters, but their accuracy is relatively high. The accuracy of triangulation range finders is on the order of tens of micrometers. Time-of-flight scanners’ accuracy can be lost when the laser hits the edge of an object because the information that is sent back to the scanner is from two different locations for one laser pulse.
The coordinate relative to the scanner’s position for a point that has hit the edge of an object will be calculated based on an average and therefore will put the point in the wrong place. When using a high resolution scan on an object the chances of the beam hitting an edge are increased and the resulting data will show noise just behind the edges of the object. Scanners with a smaller beam width will help to solve this problem but will be limited by range as the beam width will increase over distance.
Software can also help by determining that the first object to be hit by the laser beam should cancel out the second. At a rate of 10, sample points per second, low resolution scans can take less than a second, but high resolution scans, requiring millions of samples, can take minutes for some time-of-flight scanners.
The problem this creates is distortion from motion. Since each point is sampled at a different time, any motion in the subject or the scanner will distort the collected data. Thus, it is usually necessary to mount both the subject and the scanner on stable platforms and minimise vibration. Using these scanners to scan objects in motion is very difficult.
Short-range laser scanners can’t usually encompass a depth of field more than 1 meter. If the scanner is set on a tripod and there is strong sunlight on one side of the scanner then that side of the tripod will expand and slowly distort the scan data from one side to another.
Some laser scanners have level compensators built into them to counteract any movement of the scanner during the scan process. In a conoscopic system, a laser beam is projected onto the surface and then the immediate reflection along the same ray-path are put through a conoscopic crystal and projected onto a CCD. The result is a diffraction pattern , that can be frequency analyzed to determine the distance to the measured surface.
The main advantage with conoscopic holography is that only a single ray-path is needed for measuring, thus giving an opportunity to measure for instance the depth of a finely drilled hole. Hand-held laser scanners create a 3D image through the triangulation mechanism described above: a laser dot or line is projected onto an object from a hand-held device and a sensor typically a charge-coupled device or position sensitive device measures the distance to the surface.
Data is collected in relation to an internal coordinate system and therefore to collect data where the scanner is in motion the position of the scanner must be determined. The position can be determined by the scanner using reference features on the surface being scanned typically adhesive reflective tabs, but natural features have been also used in research work [25] [26] or by using an external tracking method. External tracking often takes the form of a laser tracker to provide the sensor position with integrated camera to determine the orientation of the scanner or a photogrammetric solution using 3 or more cameras providing the complete six degrees of freedom of the scanner.
Both techniques tend to use infra red light-emitting diodes attached to the scanner which are seen by the camera s through filters providing resilience to ambient lighting. Data is collected by a computer and recorded as data points within three-dimensional space , with processing this can be converted into a triangulated mesh and then a computer-aided design model, often as non-uniform rational B-spline surfaces.
Hand-held laser scanners can combine this data with passive, visible-light sensors — which capture surface textures and colors — to build or ” reverse engineer ” a full 3D model. Structured-light 3D scanners project a pattern of light on the subject and look at the deformation of the pattern on the subject. The pattern is projected onto the subject using either an LCD projector or other stable light source. A camera, offset slightly from the pattern projector, looks at the shape of the pattern and calculates the distance of every point in the field of view.
Structured-light scanning is still a very active area of research with many research papers published each year. Perfect maps have also been proven useful as structured light patterns that solve the correspondence problem and allow for error detection and error correction. The advantage of structured-light 3D scanners is speed and precision. Instead of scanning one point at a time, structured light scanners scan multiple points or the entire field of view at once.
Scanning an entire field of view in a fraction of a second reduces or eliminates the problem of distortion from motion. Some existing systems are capable of scanning moving objects in real-time. A real-time scanner using digital fringe projection and phase-shifting technique certain kinds of structured light methods was developed, to capture, reconstruct, and render high-density details of dynamically deformable objects such as facial expressions at 40 frames per second.
Different patterns can be applied to this system, and the frame rate for capturing and data processing achieves frames per second. It can also scan isolated surfaces, for example two moving hands. Modulated light 3D scanners shine a continually changing light at the subject.
Usually the light source simply cycles its amplitude in a sinusoidal pattern. A camera detects the reflected light and the amount the pattern is shifted by determines the distance the light travelled. Modulated light also allows the scanner to ignore light from sources other than a laser, so there is no interference. Computed tomography CT is a medical imaging method which generates a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images, similarly magnetic resonance imaging is another medical imaging technique that provides much greater contrast between the different soft tissues of the body than computed tomography CT does, making it especially useful in neurological brain , musculoskeletal, cardiovascular, and oncological cancer imaging.
These techniques produce a discrete 3D volumetric representation that can be directly visualised , manipulated or converted to traditional 3D surface by mean of isosurface extraction algorithms. Although most common in medicine, industrial computed tomography , microtomography and MRI are also used in other fields for acquiring a digital representation of an object and its interior, such as non destructive materials testing, reverse engineering , or studying biological and paleontological specimens.
Passive 3D imaging solutions do not emit any kind of radiation themselves, but instead rely on detecting reflected ambient radiation. Most solutions of this type detect visible light because it is a readily available ambient radiation. Other types of radiation, such as infra red could also be used. Passive methods can be very cheap, because in most cases they do not need particular hardware but simple digital cameras.

Sign In. Finally, the two models are merged with different resolutions to obtain a 3D model. Using an airborne laser altimeter, Haala, Brenner and Anders combined height data with the existing ground plans of buildings. The ground plans of buildings had already been acquired either in analog form by maps and plans or digitally in a 2D GIS. The project was done in order to enable an automatic data capture by the integration of these different types of information.
Afterwards virtual reality city models are generated in the project by texture processing, e. The project demonstrated the feasibility of rapid acquisition of 3D urban GIS. Ground plans proved are another very important source of information for 3D building reconstruction. Compared to results of automatic procedures, these ground plans proved more reliable since they contain aggregated information which has been made explicit by human interpretation. For this reason, ground plans, can considerably reduce costs in a reconstruction project.
An example of existing ground plan data usable in building reconstruction is the Digital Cadastral map , which provides information on the distribution of property, including the borders of all agricultural areas and the ground plans of existing buildings.
Additionally information as street names and the usage of buildings e. At the moment the Digital Cadastral map is built up as a database covering an area, mainly composed by digitizing preexisting maps or plans.
The point clouds produced by 3D scanners and 3D imaging can be used directly for measurement and visualisation in the architecture and construction world. These CAD models describe not simply the envelope or shape of the object, but CAD models also embody the “design intent” i. An example of design intent not evident in the shape alone might be a brake drum’s lug bolts, which must be concentric with the hole in the centre of the drum.
This knowledge would drive the sequence and method of creating the CAD model; a designer with an awareness of this relationship would not design the lug bolts referenced to the outside diameter, but instead, to the center.
Vendors offer different approaches to getting to the parametric CAD model. Others use the scan data to create an editable and verifiable feature based model that is imported into CAD with full feature tree intact, yielding a complete, native CAD model, capturing both shape and design intent e. Geomagic , Rapidform. Still other CAD applications are robust enough to manipulate limited points or polygon models within the CAD environment e.
CT , industrial CT , MRI , or micro-CT scanners do not produce point clouds but a set of 2D slices each termed a “tomogram” which are then ‘stacked together’ to produce a 3D representation.
There are several ways to do this depending on the output required:. Laser scanning describes the general method to sample or scan a surface using laser technology. Several areas of application exist that mainly differ in the power of the lasers that are used, and in the results of the scanning process.
Low laser power is used when the scanned surface doesn’t have to be influenced, e. Confocal or 3D laser scanning are methods to get information about the scanned surface. Another low-power application uses structured light projection systems for solar cell flatness metrology, [40] enabling stress calculation throughout in excess of wafers per hour. The laser power used for laser scanning equipment in industrial applications is typically less than 1W.
The power level is usually on the order of mW or less but sometimes more. Stereo photogrammetry or photogrammetry based on a block of overlapped images is the primary approach for 3D mapping and object reconstruction using 2D images. Close-range photogrammetry has also matured to the level where cameras or digital cameras can be used to capture the close-look images of objects, e.
An example of software which could do this is Vexcel FotoG 5. A semi-automatic method for acquiring 3D topologically structured data from 2D aerial stereo images has been presented by Sisi Zlatanova. Each reconstructed object is validated by superimposition of its wire frame graphics in the stereo model. The topologically structured 3D data is stored in a database and are also used for visualization of the objects.
Notable software used for 3D data acquisition using 2D images include e. A method for semi-automatic building extraction together with a concept for storing building models alongside terrain and other topographic data in a topographical information system has been developed by Franz Rottensteiner.
His approach was based on the integration of building parameter estimations into the photogrammetry process applying a hybrid modeling scheme. Buildings are decomposed into a set of simple primitives that are reconstructed individually and are then combined by Boolean operators. The internal data structure of both the primitives and the compound building models are based on the boundary representation methods [51] [52]. Multiple images are used in Zeng’s approach to surface reconstruction from multiple images.
A central idea is to explore the integration of both 3D stereo data and 2D calibrated images. This approach is motivated by the fact that only robust and accurate feature points that survived the geometry scrutiny of multiple images are reconstructed in space.
The density insufficiency and the inevitable holes in the stereo data should then be filled in by using information from multiple images. The idea is thus to first construct small surface patches from stereo points, then to progressively propagate only reliable patches in their neighborhood from images into the whole surface using a best-first strategy.
The problem thus reduces to searching for an optimal local surface patch going through a given set of stereo points from images. Multi-spectral images are also used for 3D building detection. The first and last pulse data and the normalized difference vegetation index are used in the process. New measurement techniques are also employed to obtain measurements of and between objects from single images by using the projection, or the shadow as well as their combination.
This technology is gaining attention given its fast processing time, and far lower cost than stereo measurements. In cases where a real-world equivalent of a model exists, it is much faster to scan the real-world object than to manually create a model using 3D modeling software.
Frequently, artists sculpt physical models of what they want and scan them into digital form rather than directly creating digital models on a computer. An augmented reality menu for the Madrid restaurant chain 80 Degrees [65]. Reverse engineering of a mechanical component requires a precise digital model of the objects to be reproduced. Rather than a set of points a precise digital model can be represented by a polygon mesh , a set of flat or curved NURBS surfaces, or ideally for mechanical components, a CAD solid model.
A 3D scanner can be used to digitise free-form or gradually changing shaped components as well as prismatic geometries whereas a coordinate measuring machine is usually used only to determine simple dimensions of a highly prismatic model. These data points are then processed to create a usable digital model, usually using specialized reverse engineering software. Land or buildings can be scanned into a 3D model, which allows buyers to tour and inspect the property remotely, anywhere, without having to be present at the property.
The environment at a place of interest can be captured and converted into a 3D model. This model can then be explored by the public, either through a VR interface or a traditional “2D” interface. This allows the user to explore locations which are inconvenient for travel. There have been many research projects undertaken via the scanning of historical sites and artifacts both for documentation and analysis purposes.
The combined use of 3D scanning and 3D printing technologies allows the replication of real objects without the use of traditional plaster casting techniques, that in many cases can be too invasive for being performed on precious or delicate cultural heritage artifacts.
The resulting digital 3D model was fed to a rapid prototyping machine to create a real resin replica of the original object. Creation of 3D models for Museums and Archaeological artifacts [74] [75] [76].
In , two different research groups started scanning Michelangelo’s statues. Stanford University with a group led by Marc Levoy [77] used a custom laser triangulation scanner built by Cyberware to scan Michelangelo’s statues in Florence, notably the David , the Prigioni and the four statues in The Medici Chapel.
The scans produced a data point density of one sample per 0. These detailed scans produced a large amount of data up to 32 gigabytes and processing the data from his scans took 5 months. Approximately in the same period a research group from IBM , led by H. Rushmeier and F. The digital model, result of the Stanford scanning campaign, was thoroughly used in the subsequent restoration of the statue.
In , David Luebke, et al. The scanner data was later combined with colour data from digital photographs to create the Virtual Monticello, and the Jefferson’s Cabinet exhibits in the New Orleans Museum of Art in The Virtual Monticello exhibit simulated a window looking into Jefferson’s Library. The exhibit consisted of a rear projection display on a wall and a pair of stereo glasses for the viewer.
The glasses, combined with polarised projectors, provided a 3D effect. Position tracking hardware on the glasses allowed the display to adapt as the viewer moves around, creating the illusion that the display is actually a hole in the wall looking into Jefferson’s Library. The Jefferson’s Cabinet exhibit was a barrier stereogram essentially a non-active hologram that appears different from different angles of Jefferson’s Cabinet.
The first 3D models of cuneiform tablets were acquired in Germany in A fire on March 16, , burned down much of the Muzibu Azaala Mpanga structure, and reconstruction work is likely to lean heavily upon the dataset produced by the 3D scan mission. In , Gabriele Guidi, et al.
