For analyzing the size and distance of objects in video, we build a physical distance measurement model based on the geometric transformation of pixel and space points by different shooting environments and shooting methods, and realize the measurement of the size and distance of the physical object in the picture and the distance between the shooting point and the physical object in the picture.
