摘要
三维激光扫描技术能够在三维空间内实现精确获取目标对象的位置、形态和尺寸,其数据的完整性、丰富性与其高效的作业效率均明显优于传统测绘技术。本文以船载三维激光扫描仪实时动态扫描海堤及两侧抛石,构建高精度三维模型,并对数据结果精度进行对比分析,可以获得符合要求的目标物体高精度的三维点云信息,作业效率得到了极大提高,在海岸工程测量中具有广泛的应用前景。
Three-dimensional laser scanning technology can achieve accurate acquisition of the target's position,shape and size,and its data integrity,rich and efficient operating efficiency are better than the traditional surveying technology.This paper boats carrying 3Dlaser scanner dynamic real-time scanning of seawall and on both sides of the riprap,3D modeling of the high accuracy,and the accuracy of the data results were compared and analyzed,and can meet the requirements of the object of high precision3 Dpoint cloud information.Surveying work efficiency has been greatly improved.Three-dimensional laser scanning technology has broad application prospects in the coastal engineering survey.
