同帧画幅的脱靶量单目摄像测量与计算

摘要

提出了一种采用同帧画幅和标识物的脱靶量单目摄像测量与计算方法.建立了同帧画幅的脱靶量计算模型,对影响计算精度的相关参数进行了仿真分析,采用实际图像对计算方法进行了验证.结果表明,这种测量计算方法相对简单,采用同帧画幅抵消了一定量的系统误差,目标定位精度高,可以满足脱靶量测量与计算要求.%A special monocular videometric measurement and calculation method was proposed to measure the miss distance in the same-frame film based on calibration.The miss distance calculation model was derived in the same-frame film.The parameters which affect the accuracy assessment were simulated and the actual test images were used to validate the calculation method.All the results show that the proposed method is comparatively simple and can counteract some system error in the same frame film.The target positioning accuracy is higher and can meet the need of miss distance calculation.
