基于摄影过程的实景三维模型暗面提取方法
Method for extracting shadows in real-world 3D models based on the photographic process
摘要
Abstract
This study addressed the issue of shadows in real-world three-dimensional(3D)models caused by object occlusion.It analyzed the principles behind the formation of occluded areas in images.A method for extracting occluded regions in real-world 3D models based on the photographic process was proposed,involving the construction of a process model,calculation of object occlusion relationships,and reverse deduction of photographic moments,ultimately achieving the extraction of occluded areas in 3D models.The method was tested on partial models from Dezhou,and the extraction results met expectations,seamlessly connecting with the model and providing accurate shadow boundaries for texture optimization of the real-world 3D model.关键词
