| 摘 要： | 针对目前基于内容的三维模型检索技术研究中,未将面向制造工艺的工程图尺寸数据融入三维模型检索,提出一种方法分别对三维模型进行投影变化和对工程图进行三视图分离,提取相应数据,然后对提取的数据利用已有的图形匹配方法进行匹配计算,将工程图中的标注尺寸映射到三维模型相应部位。最后给出一个例子证明该方法是可行的。

| Abstract: | The existing Content-based 3D Model Retrieval Technology has not considered the dimension data of the engineering drawing which is geared to the needs the manufacturing process into it.This paper proposed a new method of projecting 3D model and separating three views drawing from engineering drawing respectively,extracting the corresponding data,then mapping the extracted dimension into the corresponding part of 3D model using existing drawing matching method.Finally the experiment shows that the method is ... |
