Automatic matching method for inspection photos of transmission lines

Abstract

The invention relates to an automatic matching method for inspection photos of transmission lines. The method comprises the following steps: 1, shooting time of each aerial photo is acquired, flight direction data of an UAV (unmanned aerial vehicle) at different time are acquired, and geographic orientation data of inspected target towers are acquired; 2, track time is taken as shooting time according to the shooting time of each aerial photo, and the flight direction data, corresponding to the track time, of the UAV are inquired, so that the flight direction data in the shooting position of each aerial photo are acquired; 3, distance calculation is performed pairwise according to the flight direction data of the shooting positions of the aerial photos and the geographic orientation data of the towers; 4, the tower with the smallest distance with the shooting position of each aerial photo is found out, the aerial photo is matched with the tower, and accordingly, all the aerial photos are matched with the towers; and 5, files are created according to tower numbers, and all the aerial photos are filed correspondingly. The aerial photos and the towers can be automatically matched with the method.

Description

technical field [0001] The invention relates to the technical field of power grid drone inspection, in particular to an automatic matching method for power transmission line inspection images after the drone inspection flight. Background technique [0002] With the widespread application of power grid drone inspection technology, each inspection flight will generate a large amount of aerial photography data, which must be matched with the corresponding tower. Due to the number of poles and towers of the inspection line, the large amount of photos, and the surrounding topography and appearance of the equipment are similar, which caused great difficulties for manual screening. [0003] At present, aerial photography processing must invite manual inspection personnel and aerial photography operators who are familiar with the terrain of surrounding towers to participate in the photo identification work to barely complete the sorting and screening of tower equipment and photos.

Problems solved by technology

Due to the number of poles and towers of the inspection line, the large amount of photos, the surrounding terrain and appearance, and the appearance of the equipment are all similar, causing great difficulties for manual screening

[0003] At present, aerial photography processing must invite manual inspection personnel and aerial photography operators who are familiar with the terrain of surrounding towers to participate in the photo identification work to barely complete the sorting and screening of tower equipment and photos. Not only is the screening difficult and the identification efficiency low, but also due to Recognition errors are prone to occur due to the influence of aerial photography angle and light problems
