Accuracy Analysis of 3D Laser Scanning Technology in Building Elevation Mapping
With the rapid development of modern buildings,traditional surveying and mapping methods can no longer meet the requirements of high precision and high efficiency.And 3D laser scanning technology has gradually become an important tool in building elevation mapping with its fast and accurate characteristics.Hence,three-dimensional laser scanning technology in building elevation surveying and mapping and its accuracy in surveying and mapping are studied in this paper.Firstly,the major problems in building elevation surveying and mapping are analyzed,and the solutions of 3D laser scanning technology are proposed for these problems.Then,the principle of 3D laser scanning technology is studied.Meanwhile,the selection and parameter setting of the laser scanner are discussed to ensure the measurement accuracy and efficiency.Then,the accuracy of 3D laser scanning technology in building fa?ade mapping was analyzed through actual measurement and data processing.The high accuracy and efficiency of the laser scanning technology is verified through comparison experiments with traditional measurement methods.
