Research on the Design of Highway Reconstruction and Expansion On-site Survey Based on Real Scene 3D Model
This paper points out that the on-site survey of highway reconstruction and expansion project is of great significance,and the utilization of real scene 3D model can effectively support the subsequent design and construction of the project.To this end,firstly,the hardware and software construction structure and possible application results of the 3D system are summarized in this paper;secondly,this paper analyzes the process and method of standard point setting,precision evaluation and real scene 3D model construction;finally,through the analysis of engineering examples,the concrete application of highway reconstruction and expansion on-site survey design is discussed.
