Research on the Application of Computer Big Data Technology in Satellite Remote Sensing Map Cartography and Geographic Information

Abstract

This article theoretically studies the process of shadow generation in remote sensing images, and obtains the quantitative relationship between the gray value of the same pixel point when there is no shadow and when there is shadow. The article uses the shadow detection and removal method of RGB color space to detect and remove the shadow of the moving target. We use mathematical morphology to complete the trimming and reconstruction of the target area. The experimental results show the effectiveness of this method.
