摘要
建筑物立面测量是老旧小区整治出新工程中的重要工作,针对传统立面测量手段存在的作业效率低、复杂建筑物细部轮廓绘制难度大等问题,引入非接触式三维激光扫描仪,研究了基于定向法的点云拼接及其点云数据处理方法,并应用于建筑物立面测量与提取中。经实践证明,该立面测量方法具有作业安全、精度高、效率高、抗干扰能力强等优势。
Building facade measurement is an important task in the old residential district,aim to the issue of the low efficiency and difficulty in drawing complex building contours based on the traditional means of facade measurement,non-contact 3D laser scanner was used in this paper,the point cloud registration based on orientation method and point cloud data processing method are studied,the methods were applied to the building facade measurement and extraction.Practice shows that the facade measurement method has the advantages of safe operation,high precision,high efficiency and strong anti-interference ability.
