Aiming to the shortage of the existent multiple visional targets tracking technology of the robot water polo game, a local target tracking method is presented based on CamShift algorithm, which is with adaptive ability and active adjustability. Firstly, the basic CamShift algorithm is introduced. Then, the tacking method is improved by including autonomous white balance adjusting and adaptive optimization. Moreover, for the five possible cases which may lead to wrong tracking, correcting mechanism are given in detail. The experiment results show that the obtained method is valid and satisfied for real time image process.
