摘　　要：3D-TOF相机具有同时获取目标的灰度和深度图像的功能,从而能够实时得到目标物体的三维点云,实现三维成像.主要介绍了3D-TOF相机的工作机理以及应用场景等,同时模拟空间近距离目标探测的应用对目标进行成像研究,分析了不同条件下对目标物成像的影响因素以及相机的误差来源和误差的校正方法,并通过相机对深度信息的获取,对相机的距离探测精度进行了测试.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.
