Abstract:

In order to obtain false color digital mine model construction taking an open pit mine in Shandong as the case，by making the point cloud pre-processing，the traditional three-dimensional modeling，and then giving false color information via traditional point cloud data on the three-dimensional model，re-modeling，and finally formed the entire mining and false color three-dimensional model of the building’s largest mining.The model also be used to conduct a detailed application aspects of the practice of calculating mine reserves.The point transport data generated by TLS，point cloud data generated by IDL programming process，using geomagic software modeling methods，the false-color three-dimensional model was construct which can finally get a good guide to the actual production.Get the point cloud data from research to final spending five days to build the model，false color three-dimensional model of the ultimate resolution of two meters to build a traditional digital topographic maps a month workload can not be achieved，fully demonstrated by constructing a three-dimensional scanning mine the way the model can greatly reduce the computational workload and working hours，and more realistic.

Key words: TLS, scan data, point cloud pretreatment, false color, three-dimensional model
