【摘要】 分析双CCD交汇测量系统中测量精度有效视场与基线长度、像机仰角和视场角三个参数之间的数学关系;提出了根据有效视场来确定最优参数的设计方法———最小基线法.像机仰角不满足正交条件时,该方法提供了一条切实可行的参考依据.最后在MATLAB中进行计算分析,验证了该方法的正确可行.更多还原

【Abstract】 In dual-CCD non-orthogonal intersection measurement system,distance between two CCDs,elevation angle and viewing angle are three most important factors for final precision of outcomes.Firstly,this paper establishes the equitation between them and Effective Viewing Field(EVF),then discusses their relations with average errors;finally,a new least-distance calculating procedure based on MATLAB to optimize parameters is analysed and its outcome is offered,which verifies the correct of analysis in return.更多还原
