Abstract
Attributed to the ability of three-dimensional scene direct acquisition in real-time, Time of flight (TOF) camera has been developed rapidly. Several products are already active in the consumer electronics market. Such as Mesa Imaging SwissRangers SR4500 and Microsofts Kinect V2. Because of the problem of low resolution and accuracy, all of them are still difficult to be widely used. If these parameters can be further improved, TOF camera will win a place in the field of automatic navigation, machine vision and so on. In this paper, the imaging accuracy error caused by measuring distance and target reflectivity is analyzed. For the problem, that the weaker returned energy from the target is, the worse the imaging accuracy is, we proposed an automatic illumination system (AIS) which includes a distance weighted average metering (DWAM). It can solve the problem of imaging accuracy decline caused by the decrease of returned light energy and improve the dynamic performance of TOF camera.
