新型三维激光扫描仪在竣工测量的应用

Application of New 3D Laser Scanner in Completion Survey

摘要: 伴随着我国高速发展的经济，构筑物、建筑物等设施也在迅速增加，建筑物竣工测量成为目前测绘领域极为重要的一部分。传统建筑物竣工测量主要技术手段为全站仪野外实测，存在作业时间长、作业环境复杂等问题。随着测绘软硬件设备的不断发展，测绘行业也正面临转型发展，测绘人开始尝试将三维激光扫描仪应用于竣工测量中。作为一种新型三维激光扫描仪，徕卡RTC360极速三维激光扫描仪是一款具有扫描速度快、操作简单等显著优势的测绘新装备，能够在短时间内获取海量高精点云数据以及高清影像数据，极大帮助了外业数据采集效率的提升。本文引入该新型三维激光扫描仪进行建筑物竣工测量外业实测，利用该系统自带点云数据拼接与处理软件进行内业数据处理，在合格的点云数据基础之上进行竣工图的绘制。试验结果表明，基于新型三维激光扫描仪的建筑物竣工测量成果精度满足项目要求，并且在效率上优于全站仪与常规三维激光扫描仪，具有良好的应用前景。

Abstract: China’s economy and society are in a rapid development stage, and buildings, structures and other facilities are also increasing rapidly. Building completion survey has become an extremely im-portant part of the current surveying and mapping field. The main technical means of traditional building completion survey is field measurement with total station, which has problems such as long operation time and complex operation environment. With the continuous development of sur-veying and mapping software and hardware equipment, the surveying and mapping industry is also facing transformation and development. Surveyors have begun to try to apply 3D laser scanners to the completion survey. As a new type of 3D laser scanner, Leica RTC360 ultra-fast 3D laser scanner is a new surveying and mapping equipment with significant advantages such as fast scanning speed and simple operation. It can obtain massive high-precision point cloud data and high-definition im-age data in a short time, greatly helping to improve the efficiency of field data collection. In this pa-per, the new 3D laser scanner is introduced to carry out the field measurement of building comple-tion survey, and the system’s own point cloud data splicing and processing software is used to pro-cess the office data, and the completion topographic map is drawn according to the point cloud data meeting the production conditions. The test results show that the accuracy of the building comple-tion survey results based on the new 3D laser scanner meets the project requirements, and is supe-rior to the total station and the conventional 3D laser scanner in efficiency, and has a good applica-tion prospect.
