摘要
近四十多年来,虽然针对工程图的三维重建研究已经取了较大的进展,对工程图内几何信息与拓扑处理提取方法不断完善,可以在算法约束范围内完成简单形体的三维重建工作,但离达到工业化生产标准还有一段距离。在整个重建过程中,三维重建算法的建立是重建工作的核心,也使得三维重建算法成为整个重建过程的突破口。为此,对基于工程图的三维重建算法进行整理,从历史和国内外角度对典型三维重建算法进行梳理与归类,剖析了现阶段三维实体重建工作所遇到的瓶颈,并指出下一步的研究方向。
Nearly forty years, although based on three dimensional reconstruction of engineering drawing has taken great progress, Constantly improve the engineering drawing geometry information and topology processing extraction method, The simple form can be done within constraints algorithm of 3D reconstruction, but to achieve industrial production standard is still some distance. In the whole process of reconstruction, the establishment of three-dimensional reconstruction algorithm is the core of the reconstruction work, and also makes the three-dimensional reconstruction algorithm to become a breakthrough in the whole process of reconstruction~ Therefore, Compiled in engineering drawing for 3D reconstruction algorithm, from a historical and international angle of typical 3D reconstruction algorithms to sort out and classify the analysis of the present 3D reconstruction encountered the bottleneck, and pointed out the next research direction
