Description

Technical Field

[0001] This application relates to the technical field of measuring the distance between a target object and a power transmission line, and in particular to a method and system for measuring the distance between a target object and a power transmission line based on a three-dimensional point cloud. Background Technology

[0002] Existing power transmission lines use cameras for online monitoring of potential damage from large mechanical forces. However, the spatial distance information between multiple cameras cannot be effectively fused, leading to incalculable distance errors when measured based on purely visual perception. This results in difficulties in accurately calculating the distance between the object causing the damage and the power transmission line, causing significant errors in the measured distance. Furthermore, the efficiency of distance calculation based on purely visual perception is low, failing to meet the need for dynamic warnings of potential damage risks based on the real-time distance between the target object and the power transmission line. Summary of the Invention

[0003] This application provides a method and system for measuring the distance between a target object and a power transmission line based on a three-dimensional point cloud, and aims to optimize the relevant technical solutions.

Using these points as the origin of the coordinate system, a three-dimensional coordinate system is constructed for each point on the transmission line that needs protection. Warning zones indicating that the points are susceptible to damage from external forces are set up around each point. Extract the points within the warning area that is vulnerable to external force damage, obtain the three-dimensional coordinates of all points within the warning area in the three-dimensional coordinate system, and construct a three-dimensional point cloud of the warning area that is vulnerable to external force damage. Using all the three-dimensional coordinates in the three-dimensional point cloud of the vulnerability warning system, calculate the distance between all points in the vulnerability warning area and the points on the power transmission line that need to be protected. Take the maximum distance among all the distances between the points in the vulnerability warning area and the points on the power transmission line that need to be protected as the external force damage warning distance. When an object is detected approaching a point on the power transmission line that needs protection, the object is set as a target object. The three-dimensional point cloud of the target object in the three-dimensional coordinates is acquired in real time. Based on the real-time acquired three-dimensional point cloud of the target object, the average real-time distance between all points on the target object and the points on the power transmission line that need protection is calculated. When the average real-time distance is less than or equal to the value of the external force damage warning distance, the target object is marked as an object with potential external force damage.
