Complement Power Line with Point Movement

Point clouds captured by LiDAR are widely used in power line maintenance, where the completeness of the point cloud is essential in many applications. Due to the performance of LiDAR equipment, acquisition operations, and other factors, there are missing parts in the captured point cloud of power line. This paper presents a simple but effective method that complements for the missing part of the point cloud with the non-missing part of the power line. By coordinate transformation, the point clouds of all candidate power lines are aligned to the required position. It is very easy to move the transformed points to fill in the missing part of the power line, which can be achieved by only addition and subtraction operations. This paper presents our specific methods of coordinate transformation and point cloud movement for power line complement. The effectiveness of our method is verified by complementing in 59 missing point cloud fragments of the power line.
