Abstract:  3DTOF camera can obtain the amplitude and depth map of target at the same time. Threedimension clouds of points of target are achieved at real time, which is a fine technology for threedimension imaging. In this paper, we introduce the operational principle and application scenarios of 3DTOF camera, and take a picture of target imitating the application of detection of short range target in the space. At the same time, we analyze the influence factors of imaging in different conditions, and the source of deviation and calibration methods. While, via the achievement of depth information, we test accuracy of distance detection.
