What Is the General Density of Power Inspection Points?

What is the general density of power inspection points? Regular inspections of transmission lines can effectively eliminate possible hidden dangers or losses and ensure the safety of power grid operation. However, manual line inspection is labor-intensive and inefficient, and it is dangerous when inspecting high-voltage lines, and it is helpless for transmission lines that pass through barren mountains, wild ridges, and deep valleys. At this time, airborne lidar comes in handy and shows its talents. In recent years, it has been gradually accepted and promoted by the power sector.

The point cloud density of LiDAR data is one of the main factors affecting the quality of the results, and high-density point cloud data can help improve the quality of LiDAR data results. However, a substantial increase in point cloud density not only increases the cost, but also leads to an increase in the amount of data, which affects the speed of data processing and increases the cost of data storage.

After a large number of airborne LiDAR power line inspection operations, Feiyan Remote Sensing concluded that the point cloud density that meets the requirements of fast power line inspection has a reasonable range, that is, the point cloud density of towers reaches 40-50 points per square meter, and the point cloud density of power lines reaches 40-50 points per square meter. Reach 5-12 points per square meter.
