Underground Tunnel Scene Roaming System Design Based on 3D Laser Radar
JIANG Shengfeng
Abstract：In order to achieve the underground tunnel internal roaming function ,the whole path roaming system used for the trajectory of the camera during roaming was designed .This system used the 3D laser radar to obtain three‐dimension‐al point cloud data ,first through point cloud processing ,then by determining the next sampling point in the neighborhood and calculated value ,and established centerline branch and extension and connection ,the neighborhood radius extraction roadway centerline was expanded gradually ,according to the user given initial nodes and target nodes ,A * algorithm was used to search the shortest roaming path ,scene roaming was realized .The results showed that ,based on underground tunnel scene roaming of this system meet the large mining roadway internal three‐dimensional scene fast inspection function .
