In order to effectively monitor the operation status of the substation and ensure the stationarity of subway operation,a visual mod-eling method of subway substation based on point cloud data processing method is researched.After collecting the 3D point cloud data of the substation by UAV tilt photography,the point cloud data are processed,and the ICP algorithm is used to complete the data matching.Then the point cloud data is imported into Revit software to build the basic visual model,and then the whole mod-el is obtained by seamless stitching using the parcel map rendering method.Finally,the final substation visual model is obtained through the enhancement processing of bilinear light intensity interpolation method.Experimental results show that the model constructed by this method has stability and fluency,moderate brightness and darkness,and clear internal details,which can be used in the actual subway substation monitoring work to ensure the stable and safe operation of subway.
