摘要
GNSS RTK具有定位精度高、操作便捷、费用低等优点,而近年来快速发展的三维激光扫描技术则具备扫描速度快、数据信息量大、相对精度高、作业安全等特点。本文以重庆市十一条道路组成的某路网工程为例,介绍GNSS RTK与三维激光扫描技术相结合在道路工程中的应用,两种技术优势互补,取得了非常好的应用效果。
GNSS RTK has the advantages of high positioning accuracy,convenient operation and low cost,and the 3D laser scanning technology with rapid development in recent years has the characteristics of fast scanning speed,large amount of data information,high relative accuracy and safe operation.Taking a road network project composed of 11 roads in Chongqing as an example,this paper introduces the application of GNSS RTK combined with 3D laser scanning technology in road engineering,and the advantages of the two technologies complement each other and achieve very good application results.
