视觉技术在坦克火炮运动参数测量中的应用

Application of Visual Technology for Tank Gun’s Motion Parameters

摘要:

为准确、便捷地测量坦克火炮运动参数,设计了一套基于视觉检测技术的测试系统。首先利用平面标定法对系统成像模型进行标定；然后基于迭代寻优的思路,采用动态阈值对光斑图像进行分割,并利用最小二乘法进行圆周拟合,结合光斑的几何特点进行光斑有效性判定,进而迭代获取最优的定位结果；最后结合光斑在投影靶标上的运行距离和时间,获得坦克火炮运动参数。实验结果表明,测试系统能够适应复杂的光照环境,满足对测量精度、重复性、便捷性的要求。
