Study of Photoelectric Passive Ranging Technology

In order to improve the precision,accuracy,rate and anti-jamming capability of the binocular vision range finding,the key technologies such as image pretreatment,matching arithmetic and search strategy were studied.The improved product correlation match arithmetic was set up,and the search strategy combines primary and exact match arithmetic and curve fitting were applied,quick binocular stereo aim range find was realized.It's proved that this arithmetic can effectively reduce some factors influence such as noise and difference in light power and image contrast of two eyes,this distance measurement system is very well on precision,stability and real-time.
