摘要
使用卫星定位接收机、全站仪、测距仪等传统测绘方法进行建筑物立面图测绘时受立面结构和现场条件影响,往往施测难度大、作业效率低,难以满足工程应用需求.为解决这一工程难题,基于扫描仪原理分析和工作实践,本文采用地面三维激光扫描、全景采集、点云处理、立面正射影像生成等技术构建了一套完整的建筑物立面数据采集和立面图绘制方案.实践证明,方案精度可靠、稳定高效,较传统测绘方法具有明显优势,适用于当前各类城市建筑外立面改造时的立面图绘制.
Abstract
Traditional surveying and mapping methods,which rely on satellite positioning receivers,total stations,distance meters,and other equipment,often face difficulties in accurately surveying building facades due to the influence of structural and site conditions,resulting in low operational efficiency and failing to meet the needs of engineering applications. To address this engineering challenge,a comprehensive set of solutions for building facade data acquisition and facade drawing was developed through an analysis of scanner principles and practical experiences. The solutions utilized technologies such as ground-based three-dimensional (3D) laser scanning,panoramic image acquisition,point cloud processing,and facade orthorectification image generation. Practical applications have demonstrated the solutions' accuracy,reliability,stability,and efficiency,verifying their significant advantages over traditional surveying and mapping methods. The solutions are well-suited for facade drawing in current urban building renovations.
