摘要
激光扫描技术具有快速性,不接触性,实时、动态、主动性,高密度、高精度,数字化、自动化等特性,正好适用于露天矿的地面和地下测量。用露天矿的激光扫描数据,建立了露天采区三维高精度模型,为矿山设计、矿山生产及数据动态管理提供可靠信息,另外把激光扫描技术用于地下巷道进行测量,迅速建立好巷道模型,直观地获取了各巷道之间的空间关系,为"数字矿山"提供全面、高精度数据。提出了提高坐标纠正精度的方法和月采矿量的测量原理。
There are many characteristics in 3D laser technology,such as rapid,non-contact,real-time,dynamic,initiative,high-density,high-precision,digital,automation,and so on,so it can be applied in the surface and underground surveying of open-pit.Based on the data of 3D laser scanner,a high accuracy 3D model is set up to provide the information for the mine design,mine production and dynamic data management.In addition,3D laser scan technology can be used to the underground tunnel survey with tunnel models created rapidly.Its spatial relations among tunnels are obtained through the model,providing the comprehensive and high-precision spatial data for digital mine.Lastly,the method for improving the accuracy and the principle of coordinate correction are presented.
