3D Visualization Technique of Transmission Line Corridors: System Design and Implementation

doi:10.11930.2015.2.98

Abstract

Abstract: To fulfill the demand of transmission line inspection and maintenance, a transmission line corridor 3D visualization system is developed by 3D modeling of the corridors with the mass laser scanning data obtained by an unmanned helicopter equipped with multiple remote sensing sensors. With this system, the Laser point cloud and its derived topology is adopted as the basic geometry reference of the transmission line corridors to achieve a high accuracy reconstruction of the real corridors status, including the geometric modeling of surrounding topography, man-made objects, power line, tower and their multispectral representing. Besides, a 3D real-time visualization can be realized for the flight process of unmanned helicopter module. Experiment using UAV borne inspection data including LiDAR data and imagery has proved the feasibility and effectiveness of this system.

Key words: unmanned helicopter, transmission line, laser scanning data, 3D visualization, transmission line corridor, simulation, system design
