In order to Study the Foundation Pit Surface Deformation Amount and its Three-Dimensional Visualization, The Surface Modeling Technique Based on the Grid-Type Discrete Point Cloud Data and Tin Data Model is proposed. Indoor Tests Show that the Minimum Value of the Maximum Residual Value of this Technology is 0.5612~0.9993, Which Meets the Requirements of the Software Spatial Coordinate Solution and Three-Dimensional Reconstruction. And Monitoring the Application Test, the Actual Value and Calculation Value Error is Less Than 1mm, Accuracy and Error Meet the Requirements of the Engineering Measurement Specifications. Finally, the Feasibility of the Technology is Verified by the Field Test.
