The input includes data recorded by two 2D laser scanners, orthogonally mounted on the UAV, and an inertial measurement unit (IMU). To achieve the goal, algorithms are developed to process the data collected. They are separated into three major groups: (i) the data registration and filtering to generate a 3D model of the structure and control the density of point clouds for data completeness enhancement; (ii) the surface and obstacle detection to assist the UAV in monitoring tasks; and (iii) the waypoint generation to set the flight path. Experiments on different data sets show that the developed system is able to reconstruct a 3D point cloud of the structure, extract its surfaces and objects, and generate waypoints for the UAV to accomplish inspection tasks. date: 2016-11-13 type: Conference or Workshop Item type: PeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/2390/1/1612.07850.pdf identifier: Phung, Manh Duong and Quach, Cong Hoang and Chu, Duc Trinh and Nguyen, Ngoc Que and Dinh, Tran Hiep and Ha, Quang (2016) Automatic Interpretation of Unordered Point Cloud Data for UAV Navigation in Construction.
