Abstract

The invention discloses a real-time splicing method and system for UAV remote sensing images, which includes: receiving aerial photography data returned by the UAV in real time, including: real-time aerial photography images and corresponding POS data; positioning and directional images to obtain images based on POS data Geographic information; correct image lens distortion based on the inner azimuth elements of the UAV camera, geometrically correct the image based on the outer azimuth elements in the POS data, and register the corrected image based on the image location information obtained in step 2; registration The resulting images are sliced; the tiles obtained by splicing and slicing are merged and published as a standard map service for browser use; the method and system can locate, orient, correct and splice the images returned by the drone in real time, and present the unmanned aerial vehicle in real time A full-scale real-life map of the aerial photography area.

Description

technical field [0001] The invention relates to the technical field of UAV remote sensing image processing, in particular to a method and system for real-time splicing of UAV remote sensing images. Background technique [0002] At present, drone aerial survey mainly obtains remote sensing images through drone aerial photography in the field, and offline processing of images in the office provides map services. This kind of technical process is complicated, the internal and external industries are separated, and the response cycle is long, which cannot meet the application scenarios that require rapid response. In addition, real-time live broadcast video data of drones can only obtain local area information, and cannot provide real-time global situation. [0003] In scenarios such as emergency rescue that require high real-time response speed, aerial survey operations are required to process remote sensing images in real time and provide global situation map services. Cont...
