Inclination Monitoring of Coal Transporting Trestle Support Based on Ground Three-dimensional Laser Scanning Technology

On the basis of the research of ground three-dimensional laser scanning technology in deformation monitoring data processing and data analysis method, combined the characteristics of coal transporting trestle support and point cloud data, we proposed the method of using steel columns spaced extraction section to take center coordinate from coal transportation support, and then calculated the offset and inclination rate with weighted average. And the feasibility of this method is verified by experiment.
