基于模型定义的三维模型信息完备性检查技术研究
Research on Information Completeness Checking Technique of 3D Model for MBD
摘要
Abstract
Aiming at the problems of non-standard information labeling,difficult diagnosis of structural differences,lack of dimensional redundancy and low efficiency of manual detection for 3D model information,a holistic completeness check method was proposed.By calling the application programming interface(API)functions of the 3D computer-aided design(CAD)software,secondary development of the inspection modules was carried out to complete the inspection and correction of 3D model information for MBD technology.Automatic capture of the basic direction view of the MBD model was realized through secondary development of CAD software,and then OpenCV library was called through Python to compare the newly captured view with the existing model view in the data-base by using the image SSIM,and the most similar model view image was obtained.The structural difference areas between two images were extracted and highlighted through image subtraction opera-tion.Finally,the sizes of the 3D model were classified according to the classification rules,and the size completeness check was completed by DFS algorithm combined with the size redundancy missing check rule.The feasibility of the proposed method was verified by taking a cabin car product as an object.关键词
