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
enactment threshold of area
acquire middle axes of target by adopting Hough transforming and approximating and calculate obliquity angles of targets. In course of matching
accomplish missile bullet's multiple targets data association of serial images by making use of improving eigenfunction and achieve extraction of missile bullet's multiple targets after obtaining center position of targets
adopting OSTU method change numeral image into binary image
according to area of target
forecast searching region of target matching by using Kalman filter
area of targets
and abstract separately center position of targets and area of targets
judge conglutination and obstruct
then separate targets in term of wave crest and trough's variety of grey histogram of conglutination region
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. 2010 IEEE.
at the same time
obtain grey average of target
mark target region
