深度图 获取场景中各点相对于摄象机的距离是计算机视觉系统的重要任务之一．场景中各点相对于摄象机的距离可以用深度图(Depth Map)来表示，即深度图中的每一个像素值表示场景中某一点与摄像机之间的距离-Scene depth map for each point the distance relative to the camera computer vision system is one of the important tasks. Scene points relative to the distance between camera depth map can be used (Depth Map) to indicate that the depth map value of each pixel in the scene, a point that the distance between the camera
