Abstract
Urban drainage culverts take a long time to build,their geographical location is unclear,their hidden dangers are highly hidden,they are harmful,and their daily operation and maintenance are difficult.Traditional measurement and detection methods are affected by the conditions within the hidden culvert and have great limitations.They cannot accurately obtain the spatial information of the hidden culvert in a short time.Taking the application of 3D laser scanning technology in the detection and evaluation of a certain concealment in Shenzhen as an example,this paper introduces the operation process,in-house processing process and results presentation form of 3D laser scanning technology,proving that 3D laser scanning technology can quickly and accurately obtain the information of concealment.Three-dimensional spatial information and hidden danger information,summarizing the advantages and disadvantages of this technology in the detection and evaluation of hidden connotations,which can provide new methods for the detection and evaluation of hidden connotations.关键词
