| Abstract: | 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. |
