In order to better model and analyze the 3D data in goaf effectively,the goaf 3D laser scanning information visualization integration system is developed.Based on the core algorithm,the point cloud is filtered and analyzed to ensure the accuracy and speed of modeling.CVIS,a system specially used for three-dimensional laser scanning spatial information processing in goaf,Windows development platform,Visual C＋＋ development environment and OpenGL open interface are used for the development.The developed system is tested and shows good stability,reliability and strong adaptability.The system will further integrate the functions of goaf related monitoring data processing and goaf stability analysis on the existing basis,and greatly realize the safety evaluation and early warning of goaf.
