Abstract
This paper proposes a method for testing and evaluating pose measurement system based on virtu-al target instead of real target. On the basis of tracking state of theodolite and flying state of target,an algo-rithm is given to calculate the slope value and intercept value of the target image ' s centerline on image plane of theodolite. Guided by character of pose measurement system, a great deal of theoretical data and images has been simulated to test the image interpretation algorithm and pose rendezvous algorithm. Shown by experiment result, the precision of the image interpretation system can reach 0. 1 degree when the virtu-al target is as long as 80 pixels, but the precision is only 5. 7 degree when the virtual target's length is 6 pixels. Although the pose rendezvous algorithm would enlarge the interpretation error,the image interpreta-tion error is the main error source of the pose measurement.关键词
