Research and development of underground space mobile laser measurement system

摘要：

　　In view of the problems of difficulty of 3D information acquisition for underground space, the authors developed the underground space mobile laser measurement system, which is divided into dynamic measurement part and static correction part.The dynamic measurement part is highly integrated by instruments of linear array laser scanner, high precision IMU and odometer and so on.The dynamic measurement part is installed on portable mobile platform, acquiring underground space 3D point cloud information in the process of moving.The static correction part is composed of a series of three-dimensional space cooperation targets, which were distributed in underground space according to certain principle, and is equivalent to control point combination, which were used for position and orientation correction for underground mobile laser measurement system.Based on the principle of underground mobile laser measurement system, the paper focuses on several key technical problems in system integration, including hardware system integration, three dimensional cooperative target research, position and orientation correction and so on.Finally an example illustrates the high efficiency and accuracy of the system.
