Abstract:

A longrange targets automatic localization and collimation system which takes the human face as the anchor point has been developed. In order to improve the performance,the skintone detector and the face detector based on AdaBoost are used in our system. First,the skintone detector checks the available video to separate the skin area from others,then the skintone area is processed with the AdaBoost face detection method to implement realtime localization and collimation. According to the experience,for the front faces and the faces with small angles,the system has a good result. Within the distance of 300m,it localizes and collimates the targets precisely and satisfies realtime requirement. The system is able to reduce the complexity and increase the precision of localization and collimation,and is suitable for the front line of a battle and saving hostages and so on.
