【摘要】：提出一种基于虚拟大相机的光学遥感卫星多相机系统成像数据的拼接方法,实现多相机影像的高精度拼接。该方法根据各单相机的几何成像模型,构建虚拟大相机的几何成像模型;利用坐标正算、反算过程对各单相机影像进行间接法几何纠正,得到虚拟大相机图像坐标系下的各虚拟单相机影像;将各虚拟单相机影像基于影像坐标信息拼接处理后得到最终的虚拟大相机影像。该方法利用虚拟大相机实现多相机影像的高质量拼接,为后期处理提供了与之相对应的高精度有理函数模型,可用于不同数量、不同分辨率的多相机系统实现全自动智能地面预处理。
[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.
