Abstract

The invention discloses an unmanned aerial vehicle remote sensing image real-time splicing method and system, and the method comprises the steps: receiving aerial photography data returned by an unmanned aerial vehicle in real time, including a real-time aerial photography image and corresponding POS data; positioning the directional image based on the POS data to obtain geographic information ofthe image; correcting image lens distortion based on inner orientation elements of the unmanned aerial vehicle camera, correcting images based on outer orientation element geometry in POS data, and performing registration on the corrected images by combining the image position information geography obtained in the step 2; slicing the registered image; fusing the tiles obtained by splicing the slices and publishing the tiles as a standard map service for the browser end to use. Images returned by the unmanned aerial vehicle can be positioned, oriented, corrected and spliced in real time, and aglobal real-scene map of an aerial photography area of the unmanned aerial vehicle is presented in real time.

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...
