Research On On-line Intelligent Search And Tracking Algorithm Of Sea-Sky Target

To search spatial domain target on sea precisely and quickly in the condition of low contrast and low SNR, this paper present an Intelligence and on line automatic search and track for sea-sky target algorithm.Using the method of pyramid wave gate search,and decrease search area by step, image segmentation by multi-scale peak threshold, determining the optimal target by Area Marking and threshold decision, In the status of tracking, use the enhanced to the target in the wave gate, the size of gate can be adjusted adaptively according to the target size,track target by centroid detect method,get the information of target. Target location can be obtained with comprehensive forecast on Target transient occlusion situation. To re-search if not meet the target gray-scale threshold determination or forecast conditions, and to achieve intelligent search and tracking capabilities under no manual intervention. The results show that the search time in the largest region is less than19.34ms, and target recognition in the tracking state time is less than5ms. Speed, accuracy and stability fully meet the goals of modem spatial maneuvering target intelligent search and tracking system.
