Abstract

For the application environment and the necessary precision in vision coordinate measurement of bomb-fall

a corresponding method was proposed which just calibrate two key camera parameters: the focal length and the horizontal angle of the optical axis. By analyzing the coordinate calculation model

a linear calibration equation was presented

in which multiple vision sensors can derive their parameters at one time when getting two known coordinate points (target). Through analysis of precision

the optimum location of the target was given. The total errors were synthesized and the theoretical error values were obtained on every point in the measuring area. At last

the experimental results were given. The results show that the method is practical and simple for algorithm analysis

and is suitable for wide-range vision measurement

especially for field application. In the application of inspecting a

400 m area from 1 200 m away

the method can ensure that the coordinate measuring error is less than 0.3 m.
