Abstract

The invention provides a power transmission line detection method and device, computer equipment and a storage medium, and the method comprises the steps: determining a plurality of towers for supporting a power transmission line, planning a non-linear path for an aircraft above a position between two adjacent towers, generating a first threshold value in depth for the power transmission line along the path, and receiving a first threshold value in depth for the power transmission line when the aircraft flies along the path, the method comprises the following steps: calling original image data collected downwards by a camera, calling original point cloud data collected downwards by a laser radar, filtering the original point cloud data of which the depth is greater than or equal to a first threshold value, obtaining target point cloud data, projecting the target point cloud data into the original image data, obtaining candidate image data, and outputting the candidate image data. And screening multiple frames of candidate image data acquired from the same object below at different angles as multiple frames of target image data, and performing semantic recognition on the multiple frames of target image data to detect the power transmission line. The requirement for the generalization ability of deep learning is lowered, and the accuracy of power transmission line detection is improved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a detection method, device, computer equipment and storage medium of a transmission line. Background technique [0002] The transmission lines in the electric power industry are mostly deployed outdoors and directly face various weather conditions. In order to ensure the normal supply of electricity, technicians will regularly or irregularly (such as after typhoons and cold waves) use aircraft to collect image data along the transmission lines, and use deep learning to detect Power lines, so as to screen the power lines that may have abnormalities and submit them for manual review. [0003] However, the aircraft shoots down the power line from the air, and the background on the ground is very complex, such as trees, grass, gravel, rivers, roads, etc., the long-tail effect is particularly obvious, which requires high generalization ability of deep learning, but in fact It ...
