三维激光扫描技术在建筑物立面测量中的应用

Application of 3D Laser Scanning Technology in Building Elevation Survey

立面图是建筑物外观装修和景观改造设计与施工中的重要依据。传统的立面测量方法是利用全站仪采集单点数据,或者用皮尺或测距仪进行手工测量。这些方法对于结构复杂的建筑物来说,测量效率不高,精度也较低,无法准确反映建筑物的立面情况。三维激光扫描技术是近年来出现的新技术,它突破了传统的单点测量方法,具有高效率、高精度的独特优势,在国内越来越引起研究领域的关注。文章结合具体项目,阐述了利用三维激光扫描技术完成建筑物立面测量工作的具体流程,并对其关键技术进行了总结分析。结果表明,三维激光扫描技术能大大提高工作效率,具有广泛的应用前景。

Elevation is an important basis for the design and construction of building exterior decoration and landscape transformation.The traditional method of elevation measurement is to use total station to collect single point data, or use tape measure or range finder to measure manually.For buildings with complex structures, these methods are not efficient and accurate, and can not accurately reflect the facade of buildings.3 D laser scanning technology is a new technology in recent years. It breaks through the traditional single point measurement method and has the unique advantages of high efficiency and high precision. It has attracted more and more attention in the research field in China. Combined with specific projects, this paper describes the specific process of building facade measurement using 3 D laser scanning technology, and summarizes and analyzes its key technologies. The results show that 3 D laser scanning technology can greatly improve the work efficiency and has a wide application prospect.
