与传统的基于激光和红外线技术的辅助射击训练系统相比,基于图像处理技术的计算机辅助射击训练系统具有无需特殊靶子、成本较低、速度快、操作简单等优点.文章对该种系统的畸变误差进行了建模分析,给出了畸变误差随站位偏移的变化规律,并以10m气手枪射击项目为例进行了误差计算分析,结果表明:在偏离0.5m的范围内,畸变误差小于0.01个像素,对基于图像处理技术的计算机辅助训练系统可以忽略不计.
Compared with traditional shooting training system based on Laser and infrared technology,the computer-aided shoot training system based on image processing has no special target, low cost, fast and easy operation. Through the distortion error in the system of the modeling analysis,We give the rule of distortion error along with the position displacement. And then,an illustrative example based on 10 m air pistol shooting is provided that,the distortion error could be ignored in the deviation from the scope of 0. 5 m and the distortion error is less than 0.01 pixels.
