A high-speed adaptive multi-module structured light scanner

Motion capturing systems that are based on 3D models require high-speed scanning methods. One-shot structured light techniques aim at a good balance between speed and accuracy. Due to pattern interference, currently available setups capture 3D only from one single viewpoint. We propose work to enable oppositely positioned scanning modules to acquire 3D data simultaneously and thereby to speed up the acquisition even further. Key is the application of dynamic projection masks, that limit the structured light projection to the relevant part of the scene, i.e. the person. This requires tracking of the person’s outline.
