Example Embodiment

[0013] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0014] After the inspection is completed, the aerial photos need to be sorted and archived. Based on the difficulty of matching the number of photos with the tower, in order to reduce the difficulty of manual screening, the automatic matching method of the transmission line inspection image of the present invention is proposed. The main invention ideas are as follows:

[0015] After each photo is taken, an attribute of the shooting time will be generated. According to this shooting time, the geographic data at the corresponding time point of the flight track, such as longitude, latitude, etc., will be queried, and then the geographic data matched by a single photo will be matched with all towers. The geographical location is calculated, and finally the closest tower is obtained. Then match this photo to the tower.

[0016] After screening, a folder wit...

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. N...
