Abstract

3D-TOF detection technology is a new range-finding and imaging technology. The 3D-TOF camera prepared by this technology can demodulate the reflected light of different phases after the active emission light hits the target to obtain the distance information of the target point. It can obtain two-dimensional gray-scale imaging information, so the technology can obtain the three-dimensional point cloud of the target object in real time without relying on mechanical scanning, which greatly improves the speed of obtaining target information, achieves high frame rate measurement, reduces data processing difficulty, the volume weight of the sensor is greatly reduced. These advantages will enable 3D-TOF detection technology to have great development in aerospace applications. In this paper, a method for evaluating 3D-TOF camera ranging performance is studied. With this method, the performance test of 3D-TOF camera can be realized, and the influence of factors such as return light intensity and temperature on the measurement distance can be achieved. The application has high guiding significance.
