Three-dimensional point cloud reconstruction technical research based on the key points of UAV aerial

The power tower is an important part of the transmission grid. The quality of the inspection of a large amount of electric tower is an important factor in the safety of the power system. An electric pool image is constructed to realize the autonomous cruise of the UAV by three-dimensional point cloud reconstruction technology based on UAV aerial. This paper first uses the key point technology of UAV aerial image to collect important parts of the electric pole tower; then plans the cruise route based on the attributes and relative positions of different tower types and the current point position; the three-dimensional cloud and tower type templates are used to dynamically build a more accurate power tower image; finally, uses point cloud Data to dynamically plan the power tower path, and then realize UAV independent cruise, The accuracy of the method of building the method in the point cloud is verified by the construction of the actual electric tower line, and the three-dimensional reconstruction of the electric tower image is accurately realized.
