三维激光扫描技术在建筑物外立面测量中的实践及应用

Practice and application of 3D laser scanning technology in building facade measurement

三维激光扫描仪具有高速度、高精度的特点,在很多领域得到了广泛应用。文中主要对利用三维激光扫描仪进行建筑物立面面测量进行分析,通过少量的控制点,测得较多外业数据点云,利用三维数据处理软件进行数据处理,得到建筑物立面图的实际生产过程进行分析。该方法能大大缩短工期,切实提高工作效率,使大量工作转为内业处理,测量精度完全符合相关规定,该方法是一个值得推广的建筑物立面测量方法。

3D laser scanner has been widely used in many fields because of its high speed and high precision charac- teristics. This paper analyzes the building facades measurement with 3D laser scanner, in which more point clouds of field data are acquired through a small number of control points, and the actual production process was analyzed based on the data processed by 3D data processing software. This method can greatly shorten the construction period, effectively improve work efficiency and transfer a lot of work into interior process. In this way, the measurement accuracy is fully complied with relevant regulations, which proves that it should be promoted in the building facades measurement.
