摘　　要：针对特异性建筑施工检测存在难度的问题,该文提出了三维激光扫描技术应用于施工检测的方法。以某复杂长大线型空间双曲面形式的运动赛道的构件安装与混凝土表面检测为例,探讨了三维激光点云的不同处理技术。实验结果表明,该文提出的管道支架加工精度检测方法,可通过对建造好的管道支架进行三维扫描直接获取管道支架的精确三维数据,避免了人工测量管道支架,提高了测量准确度,且减少了人工工作量。同时提出的复杂空间双曲面混凝土面竣工测量方法,可充分发挥三维激光扫描技术的效率高、精度高、操作便捷的特点,可高效获取面状几何的空间三维信息,对于连续变化的空间曲面的检测具有突出优势。这两种方法可为三维激光扫描技术在类似特异性建筑施工检测中的应用提供重要技术参考。Aiming at the difficulty of specific building construction inspection,this paper proposed a method for applying 3 D laser scanning technology to construction inspection. Taking the installation of a race track in the form of a complex hyperbolic space hyperboloid and the detection of the concrete surface as examples,the different processing techniques of the 3 D laser point cloud were discussed. The experimental results showed that the method proposed in this paper could directly obtain the accurate three-dimensional data of the pipe bracket by performing a three-dimensional scan on the constructed pipe bracket,avoiding manual measurement of the pipe bracket,improving the measurement accuracy,and reducing the manual workload. In addition,a method for measuring the completion of a complex space hyperboloid concrete surface could fully take advantage of the high efficiency,high accuracy,and convenient operation of 3 D laser scanning technology. It could efficiently obtain the spatial 3 D information of planar geometry. Detection had outstanding advantages. These two methods could provide important technical references for the application of 3 D laser scanning technology in similar specific building construction inspection.
