Abstract
In order to solve the measuring velocity problem on the ground object by the Unmanned Aerial Vehicle (UAV), a measuring velocity method based on visible light is proposed. And the target orientation model is given. The principle of velocity measure is introduced in detail. The algorithm can solve the object velocity through a succession of UAV images.Practical measuring results prove that the velocity error of the algorithm can meet the demands of the ground moving object velocity measuring accuracy.
