3d cameras take 2 or more photos at once, our 3d scanning algorithm can extract z axis info from disparity between photos. We also provide extremely accurate algorithm for aerial or satellite photograph, it can match objects from 8 or more photos, and combine pointclouds from different angles.
Structure light 3d scanning is the most used method today. Based on different user requirement, we provide a fast algorithm for KINECT like applications, eg: tracking moving objects. We also provide a high precision algorithms, it is capable of auto calibration, and provide high quality results.
