Problems solved by technology

In the past, the overlapping degree inspection only considered the relationship between the overlapping side lengths of images. However, due to problems such as short baselines, irregular overlapping degrees, and excessive inclination angles in the image capture process, it is inaccurate to calculate only based on the side length relationship.

Abstract

The invention discloses an unmanned plane flying quality inspection system. It is very important for accurately inspecting unmanned plane flying quality. The unmanned plane flying quality inspection system is developed according to inspection requirements on flying quality of an unmanned plane for aerophotography. The unmanned plane flying quality inspection system can calculate flying image quality parameters such as a degree of overlapping, a swing angle, course flexibility and flying height difference by an interactive fast computing method. The unmanned plane flying quality inspection system has innovativeness in swing angle and overlapping degree calculation and can produce reliable results. Under the condition of satisfying engineering production, through a side length measurement method, an overlapping degree calculation formula is deduced, course and lateral direction overlapping degrees of unmanned plane images are acquired accurately and the problem of inaccuracy of the calculation result of the overlapping degree of flying images is solved.

Description

technical field [0001] The present invention is a system developed aiming at the inspection requirements of flight quality of UAV aerial photography. Background technique [0002] UAVs have the characteristics of low cost, high efficiency, and high resolution, but there are many problems in the UAV ingestion, such as large number, small image size, short baseline, irregular overlap and excessive inclination angle. Therefore, in order to ensure that the follow-up internal work can be completed smoothly, the quality evaluation work must be completed in the early stage. The flight quality inspection mainly includes inspections such as overlap, rotation angle, route curvature, and flight height difference. In production, many units have developed corresponding quality inspection software according to their own needs. However, the accuracy is not high when checking the overlapping degree. Considering the arrangement of flight images and the importance of flight quality inspectio...
