Research on three-dimensional visualization modeling of roadbed slope structure, presentation of vector information and development of display module

Abstract

The three-dimensional vector model of slope and structure plays an extremely important role in slope stability evaluation, engineering treatment and maintenance. A 3D visualization model of slope structure was built, the vector information was presented, and a display module was developed in this paper. To be more specific, the 3D model of slope stratum was fabricated and edited via 3DS Max. Next, the modeling flow of stratum and its optimization scheme were established. The shooting requirements and specifications were proposed for the multi-angle acquisition of handheld camera. According to the data files of structure, the file plug-ins of slope monitoring equipment were edited and fabricated through 3DS Max. Based on the superposition of 3D model, the vector information of slope structure was added to the corresponding 3D slope model to realize the presentation and display of its vector information. On this basis, functions like distance measurement and area measurement were developed in accordance with related engineering requirements, expecting to facilitate the practical engineering application.
