随着建筑物结构设计复杂程度的提高,研究新的施工放样方法,提供多样的施工途径,以应对复杂多变的建筑结构设计至关重要。提出基于图形解算的支柱施工测量方法,采用常规测量获取建筑物关键部位坐标,经过二元一次多项式趋势面拟合、B样条曲线拟合、基于特征的关键点解算等步骤完成施工放样,并以体育馆为例进行验证,其精度可满足施工要求。 As the complexity of building structure design increases, it is crucial to study new construction stakeout methods and to provide diversified construction approaches to deal with the complex and ever-changing architectural design. Proposed a method for measuring the construction of the pillar based on the graph solver. The coordinates of the key parts of the building were obtained by the routine measurement. After the polynomial trend surface fitting of the binary polynomial, B-spline curve fitting and key point solution based on the feature, , And to gymnasium as an example for verification, its accuracy to meet the construction requirements.
