The Research On Precision Track System Of Groud Rotating Platform

Video picture realizing automatic measure and automatic track, specially in gulf battle. It is in advantage of intuition, anti-jamming, high precision. By these, new armed control system almost load video system, APT technique is the kernel of the video track.This system adopt coarse and fine axis controlling scheme which is double axis and double view range. Coarse track system is used to finish scan, search and capture target. Fine track finely adjust instrument's view axis in order to advance system track precision. In this system, using drone simulate airplane, this is using running platform track drone. adopting beaconing light by CCD camera, DSP6416 distill beaconing light offset, this is displacement offset which is relative to optical center. System unscramble these data basis on protocol of video track, DC moment motor automatically track target by these data. In addition, system adopt high track precision, strong anti-jamming rectangular center arithmetic and adopt simple arithmetic, high reliability PID track control arithmetic.Experimental result indicating, this system is high reliability, fine track effect, high real time and satisfy automatic track require and accurate require.
