3D framing camera system based on sample cumulation method

摘要

A novel three-dimensional (3D) camera concept system could capture 3D image with thousands of pixels at range of several kilometer in real time was presented. The camera used a pulse laser to illuminate the scene, a solid-stat charge-couple device(CCD) sensor, and sample cumulation technology based on a gated binary image intensifier. The cumulation charges captured in CCD carried the information of range. The system was designed to have some significant advantages, such as low cost, simply schemes, high speed mainly limited to the speed of CCD frame capture. Potential applications include navigation of autonomous helicopter, large target identification, sensing and guidance, auto collision avoidance, robotic vision, atmospheric sensing and topography. In the paper, we discussed the fundamental principle and schemes of the 3D camera system based on sample cumulation and presented the feasible experiment result with a photo multiplier tube with binary character to simulate one pixel of the 3D camera system. Then we discussed the factors which influence the quality of 3D image according to the experiment result.
