High-resolution 3D optical sensing and real-time 3D video data streaming

The first part of this paper discusses the high-resolution, real-time 3D optical sensing techniques that we developed in the optics community. Such technologies could benefit the advanced intelligent mechatronics community as another sensing tool. The second part of this paper discusses our recent development on 3D sensing data compression and streaming that could open new opportunities for the mechatronics community. Our 3D optical sensing technique is based on the digital fringe projection (DFP) method that has merits of speed, resolution, and accuracy, as well flexibility when comparing with other 3D optical imaging methods. Our novel compression method drastically reduces data sizes, and through seamless integration with our 3D sensing system, allows for real-time high-quality 3D data delivery across standard wired and wireless networks. This paper introduces the basic principles of each technology and casts our perspectives on possible applications that our technologies could enable for the mechatronics community.
