With the widespread application of airborne light detection and ranging (LiDAR) technology in transmission line engineering

how to control the quality of point cloud results has become a hot research topic.There are many effective methods for controlling the quality of point cloud results in general areas of transmission lines.However

in areas with special difficulties such as high plateaus

cold regions

high mountains

deserted areas

or areas with dense vegetation

low reflectivity

and fragmented landforms

there is a lack of comprehensive control measures throughout the entire process.This article analyzes the primary and secondary factors and their degree of impact on the quality of point cloud results in various types of difficult areas of transmission lines

and proposes a quality control plan for point cloud results that is tailored to local conditions

and verified through four typical difficult engineering examples.
