The research for missile bulletsmultiple targets of opto-electronic theodolites
The system of opto-electronic theodolites for measuring missile bullet provides parameter of missile bullet trajectory and affords primacy scientific data for completing campaign assign and obtaining ideal result of destroy. This article researches extraction arithmetic for missile bullet multiple targets. Above all, adopting OSTU method change numeral image into binary image, and abstracts separately center position of targets and area of targets, at the same time, mark target region; enactment threshold of area, according to area of target, judge conglutination and obstruct; then separate targets in term of wave crest and troughs variety of grey histogram of conglutination region; obtain grey average of target; acquire middle axes of target by adopting Hough transforming and approximating and calculate obliquity angles of targets. In course of matching, forecast searching region of target matching by using Kalman filter; accomplish missile bullets multiple targets data association of serial images by making use of improving eigenfunction and achieve extraction of missile bullets multiple targets after obtaining center position of targets, area of targets, grey average of target and obliquity angles of targets. The experimental result shows that right ratio of the extraction targets reach to 90％.The article use correct mathematical model and reasonable arithmetic and obtain effectively parameter of missile bullet multiple targets.
