Title:
UNMANNED AERIAL VEHICLE MAPPING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/032942
Kind Code:
A1
Abstract:
An unmanned aerial vehicle mapping method, apparatus and system. The method comprises: after obtaining first image data of aerial photography performed on a target area by an on-board of an unmanned aerial vehicle, performing imaging detection on the first image data, and obtaining a correction parameter of the first image data; correcting redundant information in the first image data according to the correction parameter to obtain second image data; further eliminating a distortion difference in the second image data to obtain third image data; and converting the third image data into a mapping result. On this basis, by means of correction based on the correction parameter and distortion difference elimination, a negative influence of an altitude environment on unmanned aerial vehicle imaging is reduced, and the quality of the mapping result is improved.
