In order to realize the position measurements of multiple targets on the ground,a project of track recognition for multiple targets is established,and the recognition method in pixel coordinates for large area optical electronic measurement sets is researched.An evaluation function based on target motion,such as the direction,speed and the acceleration is established.According to the correlation degree between point and track decided by the evaluation function,the track recognitions for multiple targets are accomplished.By considering the losses of some points in some frames,the lost points are replenished by the track data with Kalman filter to ensure the track continuance during the course of recognition.The experimental results show that this method can recognize 50 tracks,which meets the requirements for position measurements of multiple targets.
