What is 3D Scanning?

3D scanning is a combined term for various processes involved in producing a 3D model . A 3D model is a digital form of a physical object .

Various types of 3D scanning technology

Contact based 3D Scanning

Touch probe scanning: This type of scanning involves touching various points of the surface of the physical object with a probe (usually a tip or a ball attached to an arm). This method usually collects less data and is more accurate than the light based scanning but this method takes a lot of time in most cases. This method is best used when precision is most important.
Destructive slicing: This is a process where multiple pictures of an object are taken from a fixed location. Thin slices of the object are removed between each image. The distance to the object is precisely controlled, therefore the scale of each image is known. After slicing all the way through the object, the images are stacked up in the capture software – resulting in a full 3D model of the object.

Non contact based 3D Scanning

Light based scanning: This type of scanning involves emitting different kinds of lights and detecting its reflection using a camera in order to measure the surface points of the object. The most commonly used lights include visible light, blue light, laser or x-ray. eg. CT scans (Computed tomography) use X -rays.
3D Laser Scanners can generally be categorized into three main categories – (a) Laser Triangulation (b) Time of flight (c) Phase Shift.

  • Laser Triangulation: In Laser triangulation, a laser line or a point is projecting onto an object’s surface and then its reflection is captured with a sensor located at a known distance from the laser’s source. The resulting reflection angle can be interpreted to calculate 3D measures of the surface.
  • Time of Flight: Time of flight laser scanners emit a pulse of laser light and the time it takes to make its round-trip is computed to find the distance of the point in 3D space. Taken all together, these points create a 3 dimensional point cloud that can be used to reconstruct the object. This method is typically used when scanning long distances, such as the inside of the stadium or the outside of a building.
  • Phase Shift: Phase shift laser scanners works similar to that of time of flight scanners except that a standard phase is also emitted with the laser light and the reflection of the same is also compared to refine the the distance detection.

Magnetic Resonance Imaging: 3D MRI scans are obtained by stacking a series of MRI (Magnetic Resonance Imaging) scans on each other in software. This is typically done by precisely controlling the steps in between each sectional MRI scan. The resultant data is a 3D model of the object and contains all of its physical measurements. This technology was originally developed for the medical field but is now growing into manufacturing and industrial applications as well.
