Abstract

In recent years, with the development of imaging technology based on photon time of flight (TOF) measurement, the TOF camera has gradually come into the public horizon. Compared with binocular vision and structured light 3D imaging, TOF imaging system can image the scene in real time without any processing. However, it is difficult to be widely used because of the low resolution and poor depth measurement precision. Based on the imaging theory of TOF camera, the imaging error of TOF camera is analyzed under the action of many factors. After the analysis of environmental light intensity, measurement distance and target reflectivity, the analysis of variance (ANOVA) of the collected data shows that the reflectivity of objects has more influence on the imaging error.
