Equipped with the mini camera, UAVs can be used as a surveillance device, which can be widely used in both civil fields as well as military fields. The real time video output by camera can be transferred down to the ground station and is processed to detect and localize the interested targets. A low-cost and real time circular targets detection and localization algorithm is proposed in this paper. The target is detected by image analysis based recognition method and the position is represented in UAV's coordinate frame. Further, the position is transferred to the world coordinate frame by using UAV's guidance data (position and attitude) to localize the targets. Experiment results are also given and show that the algorithm can be run in real time.
