三维激光扫描技术在建筑物顶梁中心线提取方法研究

Research on Extraction Method of Center Line of Building Top Beam by 3D Laser Scanning Technology

近年来,三维激光扫描技术由于其具有非接触性、精度和测量效率高等特点,在测绘领域广泛使用。建筑物顶梁由于在建筑顶部,传统的测量手段难以采集到其精确的三维数据。本文以某厂房为例,使用三维激光扫描技术采集顶梁数据,内业处理获取顶梁中心线坐标,对于建筑物顶梁测绘具有一定的实际指导意义。

In recent years,3D laser scanning technology is widely used in the field of surveying and mapping because of its non-contact,precision and high measurement efficiency. Because the roof beam of the building is on the top of the building,it is difficult to collect accurate three-dimensional data by traditional measuring methods. This paper takes a factory as an example,uses 3D laser scanning technology to collect the top beam data,and the internal processing to obtain the coordinates of the center line of the top beam,which has certain practical guiding significance for the mapping of the top beam of the building in the future.
