摘要
分析了摄像机投影模型和影响摄影测量精度的内外因素,针对固定视场双目视觉摄影测量应用,建立了目标特征标志提取误差、时间同步误差、安装平台形变、目标控制点特征及多帧平滑滤波算法对位置及姿态测量误差的影响模型,通过数据仿真对影响摄影测量精度的因素进行了讨论,可为靶场目标起落运动参数测量系统及其它高精度摄像测量系统设备选型、设计论证及测量精度分析验证等提供参考。
The projection model of camera and the main factors which affect the accuracy of photogrammetry are analyzed in the paper.The enor models are established,including the error model of resolution,the error model of image feature extraction,the error model of target movement and time synchronization,the deformation error model of camera installation platform,and the error model of target features.For fixed intersection angle and resolution of surface,the error simulation calculation of camera measurement is carried out.The results of the study can provide reference and support for the design and the accuracy analysis of other camera measurement system.
