The miniature aerial optical remote sensing system,which consists of a digital camera,a miniature robot plane(UAV,unmanned aerial vehicle),and a ground-based subsystem,is a new technology in remote sensing field.Images from this remote sensing system can not be corrected easily.This status quo blocks the application of the UAV remote sensing technology in various research fields.This paper presents a geometric correction method in terms of the analysis of the UAV remote sensing images.Digital camera calibration and its distortion model are finished by a standard graphic method,and the images registration is completed by large-scale topographical maps.The extrinsic camera parameters are not used in this method.The single point mean error of the corrected image map is about 1.0 meters.
