摘要

针对采用焦平面CCD交错拼接方式的测绘相机会由于存在交会角而产生视场拼接漏缝问题，本文在考虑交会角和相机无侧摆的前提下提出了一种焦平面CCD重叠像元数算法。首先，根据测绘相机成像原理建立了前视相机成像模型，分析了产生视场漏缝的原因。接着，推导出在CCD数量为奇数和偶数两种不同拼接形式下的地面视场重叠及漏缝大小的数学表达式，进而得到了不产生漏缝时CCD片间最小重叠像元数计算公式，并对误差进行了分析。最后，将该算法应用于工程算例，并对比了地球曲率对计算结果的影响。通过算例得到了各CCD片间视场漏缝及最小重叠像元数，其最大值分别为1 141.491 m，115个。应用本文方法可以近似计算应用交错拼接法的测绘相机焦平面前后排CCD的最小重叠像元数，误差小于1 pixel。

Abstract

Imaging gaps will appear in the field of view for a mapping camera due to the convergence angle when it uses a interleaving assembly of focal plane. In order to solve the problem above

an algorithm of minimum overlapping pixels was proposed by considering convergence angle and without camera pitch. Firstly

an imaging model for the front view camera was established according to the imaging principle of mapping camera. The reason that imaging gaps appear was analyzed. Then

the mathematical expressions of imaging gaps and overlaps of odd and even quantity CCD assemblies were derived

the formula for computing the minimum number overlapping pixels between adjacent CCDs that can avoid the imaging gaps was obtained

and the error was analyzed. Finally

the algorithm was applied to an engineering example

and the effect of earth curvature was analyzed. The instance shows that the imaging gaps and the minimum number of overlapping pixels in the engineering instance are 1 141.491 m and 115 in maximum respectively. It indicates that the proposed algorithm can calculate the minimum number of overlapping pixels of the mapping camera and the theoretical error is less than 1 pixel.
