Abstract

The present invention relates to the field of unmanned aerial vehicles, and specifically provides an extended Kalman filter-based unmanned aerial vehicle synchronous positioning and map construction (SLAM) technology to measure the inclination angle system, including a power tower structure model database module, and an unmanned aerial vehicle movement and measurement module , UAV data processing module and tower model reconstruction module; UAV motion and measurement module can obtain environmental maps and point cloud data of power towers based on the simultaneous positioning and map construction of extended Kalman filter; the UAV data processing module is used To fit the central axis of the power tower and calculate the inclination angle. The invention can greatly reduce the workload of the measurement of the inclination angle of the power tower, improve the work efficiency of the inspection transmission line and the power tower, improve the working speed and intelligence, reduce the labor cost, time cost and work difficulty, and increase the inclination angle of the power tower The accuracy, stability and ease of use of the measurement are more simple and easy to use, and the inclination angle can be measured efficiently and intelligently.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, and specifically provides an extended Kalman filter (EKF)-based unmanned aerial vehicle SLAM (synchronous positioning and map construction) technology for measuring inclination angle system. Background technique [0002] The power pole tower in the power line is a pole-shaped or tower-shaped structure that supports the overhead transmission line conductor and the overhead ground wire and keeps a certain distance between them and the earth. It usually adopts steel structure, wood structure and reinforced concrete structure. The centrality of the tower is related to the safety and reliability of power operation; during construction and installation, the centrality must be ensured to ensure the safe and reliable operation of the line. However, after the power line has been in operation for many years, changes in the basic geological conditions will cause uneven settlement of the power tower, ...
