A Study on the Application of 3D Laser Scanning in the Deformation Monitoring for Open-pit Mine
Deformation monitoring is a work to provide reliable data and a scientific basis for gaining knowledge and mastering the evolutionary process, catching the characteristic information in time and making a correct analysis, evaluation, prediction and control.New technology plays an important role in this research and application.In this paper, the basic principle and features of the 3D laser scanning are introduced, and the feasibility of its application in the deformation monitoring for open-pit mine is analyzed throughout a deformation monitoring case in Fushun City, China.Some unique advantages of this technology are illustrated compared with the traditional methods, such that it can fast acquire dense data with more detail information.Also it provides data in 3D visualization to make the research into a more visible way.In this article, we present the general processing flow from data acquisition to the final results, especially the information extraction based on point cloud.Some of the factors influencing the measured results are discussed based on on-site tests, including precision, registration and sensitivity.The monitoring results indicate that 3D laser scanning is a new suitable method to perform the qualitative analysis and quantitative research for deformation monitoring.It attributes to the research and application by providing a supplementary method for the real-time monitoring.It can be anticipated that the 3D laser scanning will be a very effective research tool for deformation monitoring and the health diagnosis for the land slide of open-pit mine.
