Abstract

To realize multiphysics field coupling analysis of large football stadium frame structures, a three-dimensional modeling method based on trinocular stereo vision and ABAQUS is proposed. This method acquires positional data of the frame structure, calibrates the three-camera plane for trinocular stereo measurement, and constructs a trinocular stereo vision model. Using this model, positional data of the large football stadium frame structure are obtained. Three-dimensional modeling is then completed in ABAQUS through the steps of part creation, assembly, material property definition, and meshing. Taking a large football stadium as the experimental subject, 10 sets of experiments are conducted. Camera calibration in the trinocular stereo measurement process serves as the basis for measuring the stadium frame structure. Different measurement distances, various lighting conditions, and diverse load conditions are set. The results demonstrate that the proposed method effectively accomplishes three-camera calibration for trinocular stereo measurement and obtains nonlinear analysis results such as displacement and horizontal tensile stress, showing favorable application performance.
