【摘要】 首先描述了相机光轴测量模型,提出了一种基于双矢量定姿原理的多线阵相机光轴在轨实时测量方法,给出了计算表达式,对算法误差进行了分析,并通过仿真进行了验证。此外,还对两种算法的残差进行了仿真,结果表明,简化算法仅在很小的测量范围内与双矢量算法一致性良好,但探测范围扩大时,采用该算法才能得到更准确的参数测量结果。更多还原

【Abstract】 This article first describes the camera optical axis measurement model, and proposes an optical axis measurement method for multi-line array cameras based on the dual-vector attitude determination principle. The calculation expression is given, the algorithm error is analyzed, and verified by simulation. In addition, the residuals of two algorithms are simulated, and the results show that the simplified algorithm is only in good agreement with the dual vector algorithm in a small measurement range, but when the detection range is expanded,the algorithm in this article can be used to obtain more accurate results.更多还原
