In order to realize the measurement of multiple targets position on the ground

a project of recognition for multiple targets track is established

and the recognition method in pixel coordinates for large area optical electronic measurement sets is researched . This method creates an evaluation function based on target motion

such as the direction

speed and acceleration

then decides the membership degree between point and track by the evaluation function

in this way the multiple targets track recognition is accomplished. During the curse of recognition

the author thinks the phenomenon of some points are lost in some frames

then replenishes the lose point by the track data with Kalman filter

thus the track continual isn’t destroyed. The correctness of the recognition method is affirmed by simulation and actual multiple targets track data. This method meets the requirement of multiple targets position measurement.
