Abstract

The invention provides an elimination method for gross error in unmanned aerial vehicle image matching on a cross air strip and a device thereof, and relates to the field of air survey. According to the elimination method for gross error in unmanned aerial vehicle image matching on the cross air strip, a composite gross error elimination method of different types of air strips is adopted, and gross error elimination in the same air strip, gross error elimination between parallel air strips and gross error elimination between the cross air strips are performed on the sequence of identical point pairs so that precision of the last remaining identical point pairs is enabled to be higher, the connection state is enabled to be more stable, and elimination efficiency is higher.

Description

technical field [0001] The invention relates to the field of aerial surveying, in particular to a method and a device for eliminating gross errors in UAV image matching on crossing flight belts. Background technique [0002] Aerial photography, also known as aerial photography, refers to the technology of using aerial cameras to take pictures of ground scenes on airplanes or other aviation vehicles. Classified according to the tilt angle of the photo (the tilt angle of the photo is the angle between the main optical axis of the aerial camera and the ground vertical line (main vertical line) passing through the center of the lens), the photography method can be divided into vertical photography and oblique photography. [0003] like figure 1 As shown in , after the aerial photography, the aerial photography image will be generated according to the flight direction of each flight strip (two sets of flight strips perpendicular to each other will appear). Using aerial images c...
