The technology is very impressive as regards its level of miniaturisation, especially the stereo vision camera and the projection optics. It was therefore possible to produce the smallest and lightest 3D dental scanner for intraoral applications. The system is simple and can be used on a standard PC without any previous technical knowledge. The related software developed at the AIT records all images in real time and transmits the data to the computer via a USB port. The captured data are used to generate a 3D image in real time. Thanks to the extraordinarily practical form, the 3D intraoral scanner has full mobility capability and can be utilised everywhere. The result is available in a standard format and can be used by a normal CAD/CAM system in the dental industry.
The measurement process can be visualised in real time. A complete jaw arch can be measured in 3 to 5 minutes thanks to the current processing speed of up to 6 measurement datasets per second. The measurement accuracy is approx. 20 µm for an individual measurement.
Other Application Areas for 3D / Stereo Vision
3D also harbours great potential in projects involving volume recording and quality inspection of industrial goods or in autonomous transport projects, e.g. the use of camera-based obstacle detection systems in trains or safe semi-autonomous convoy guidance, e.g. regarding supply management in international rescue missions.
