摘　　要：基于平法施工图建立钢筋三维模型的过程既需要大量时间和人力成本,又需要建模者能够理解平法施工图的表达。现有自动化建模的研究多集中于建筑模型领域,对存量较大的结构平法施工图纸利用很少。以二维板平法施工图纸为研究对象,针对板平法施工图复杂特征,引入空间位置特征、距离特征对霍夫变换结果进行限定筛分,提出了一种基于霍夫变换方法的板平法施工图信息识别方法,有效实现了板平法施工图的板块分割与支座处钢筋线条识别。并提出了基于制图规则的板平法施工图注写信息数据匹配方法,对板平法施工图注写信息进行了有效提取与输出。最后开发了信息提取与匹配算法,验证了本文研究方法的可行性。The process of establishing a three⁃dimensional model of steel reinforcement based on the construction drawings requires a lot of time and labor cost,and the modeler needs to understand the expression of construction drawing.The existing researches on automated modeling are mostly concentrated in the field of building models,and there is little use of structural plane drawings with large stocks.Taking the two⁃dimensional slab general plan drawing as the research object,in view of the complex characteristics of slab general plan drawing,the spatial position characteristics and distance characteristics were introduced to limit the screening of the Hough transform results.Information recognition method of slab general plan drawing based on the Hough transform method was proposed,which effectively realizes the plate segmentation of slab general plan drawing and the recognition of steel bar lines at the support.A annotation information data matching method of slab general plan drawing based on drawing rules was proposed,and the annotation information of slab general plan drawing was effectively extracted and output.Finally,the information extraction and matching algorithm was developed to verify the feasibility of the research method in this paper.
