摘要
分析了多镜头、多面阵CCD航空影像的几何特点;构建了利用多个面阵CCD影像合成大像幅、中心投影数字航空影像的误差模型;详细分析了影像拼接误差对成图精度的影响;同时,从理论上推导出建立多面阵CCD数字航空测量相机系统所涉及的若干关键技术指标,并通过模拟数据验证了理论分析的正确性。
The paper has analyzed the geometric characteristics of multi-lens and multi-matrix CCD images. The error model has been built using multi-matrix CCD images to synthesize a central projection virtual image with large size. Then, the influence of image joint errors for mapping precision has been analyzed in detail. At the same time, the paper has deducted some key technique indexes in the course of modeling for multi-matrix CCD digital aerial camera system. The correctness of the theoretical analysis has been validated with simulated data.
