三维激光扫描仪具有高速度、高精度的特点获取物体表面点云数据,在很多领域得到了广泛应用,三维激光扫描技术被称为实景复制技术。本文结合工程实例,应用Z+F三维激光扫描仪,对长春伪满时期某图书馆进行数据采集、处理和正射影像的生成,并将该方法和技术应用于实践。结果表明,应用三维激光扫描技术能够极大地提高建筑物立面数据采集效率并节省工程时间,提高了数据精度,降低数据处理的复杂程度,能够快速、精确的获得立面图并为城市规划提供依据。
The 3D laser scanner has the characteristics of high speed and high precision to get the point cloud data of the object surface, which has been widely used in many fields. The 3D laser scanning technology is called the real image replication technology. In this paper, the project examples, the application of Z + F 3D laser scanner, a library in Changchun pseudo-Man period data acquisition, processing and orthophoto generation, and the method and technology applied to practice. The results show that the application of 3D laser scanning technology can greatly improve the building facade data collection efficiency and save construction time, improve the data accuracy and reduce the complexity of data processing, and can quickly and accurately obtain elevation plans and provide urban planning in accordance with.
