ABSTRACT

The Time-of-Flight (TOF) camera is a new elegant choice for 3D measurement and modelling in many different fields. However, due to the different method of these new devices of the technology on the market, the knowledge of its performance is far away from enough. In particular, the distance measurements of these devices are often influenced by some systematic errors, which decrease the quality of the data a lot. To evaluate these errors, some experiments have been done on pulsed TOF cameras developed by our laboratory. In this paper, we proposed a novel calibration procedure for pulsed TOF cameras, which deal with the evaluation of the camera heating period, capture the intrinsic matrix of the camera, the measurement error of different distances and colors, and a quick transformation for coordinate.
