Title:
SYSTEM AND METHOD FOR OBTAINING AIRCRAFT PROFILE
Document Type and Number:
WIPO Patent Application WO/2023/142608
Kind Code:
A1
Abstract:
Disclosed in the present application are a method for obtaining an aircraft profile. The method comprises: establishing a three-dimensional mathematical model of an aircraft, and obtaining three-dimensional coordinates of the three-dimensional mathematical model of the aircraft in a model coordinate system; arranging a plurality of laser radars around the aircraft, and controlling each laser radar to scan a predetermined area of the aircraft so as to measure and obtain a point cloud of the predetermined area; splicing the point clouds of the plurality of predetermined areas measured by means of the plurality of laser radars; filtering the spliced point cloud to remove noise points in the spliced point cloud; and comparing the filtered point cloud of the aircraft with the three-dimensional mathematical model of the aircraft, and under the condition that an error therebetween exceeds a threshold value, reconstructing the three-dimensional mathematical model of the aircraft.
