[Abstract]:An optical remote sensing satellite multi-camera system imaging data splicing method based on virtual large camera is presented in this paper, which can realize the high-precision mosaic of multi-camera image. According to the geometric imaging model of each single camera, the geometric imaging model of virtual large camera is constructed. Each single camera image is corrected indirectly by coordinate forward calculation and inverse calculation, and the virtual single camera image in the coordinate system of virtual large camera is obtained. The virtual single camera images are combined based on the coordinate information to get the final virtual large camera images. This method uses virtual large camera to realize high-quality mosaic of multi-camera images, and provides the corresponding high-precision rational function model for post-processing, which can be used in different quantities. The multi-camera system with different resolution can realize automatic intelligent ground pretreatment.
