Title:
POWER TRANSMISSION LINE DETECTION METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/174020
Kind Code:
A1
Abstract:
A power transmission line detection method and apparatus, a computer device, and a storage medium. The method comprises: determining a plurality of pole towers for supporting power transmission lines; planning a non-linear route for an aircraft above a position between two adjacent pole towers; generating a first threshold in depth for the power transmission lines along the route; receiving original image data collected downwards by calling a camera, and original point cloud data collected downwards by calling a laser radar when the aircraft flies along the route; filtering out the original point cloud data of which the depth is greater than or equal to the first threshold to obtain target point cloud data; projecting the target point cloud data into the original image data to obtain candidate image data; screening for multiple frames of candidate image data collected from a same object below at different angles, and using the multiple frames of candidate image data as multiple frames of target image data; and performing semantic recognition on the multiple frames of target image data to detect the power transmission lines.
