摘要
城市地标建筑建模是展示城市文化的重要方式,但大多城市的地标建筑都属于异形建筑,传统的全站仪及经纬仪等测量外业采集存在作业效率低、测量难度大等问题。以某工程为例,将三维激光扫描技术应用于地标建筑外业数据采集中,结果表明,此技术可以快速、全面地获取目标物点云数据,内业建立的目标物三维模型尺寸相对偏差不超过5%,整体精度较高,具有较好的应用推广价值。
Urban landmark building modeling has become an important way to display urban culture and tourism.However,since most urban landmark buildings belong to anomalous buildings,traditional measurement methods,such as total station and theodolite,have problems such as low efficiency and difficulty in measurement.Through a project as an example,the 3D laser scanning technology is applied to the field data acquisition of landmark buildings.The research results show that the technology can quickly and comprehensively obtain the point cloud data of the target object,and the relative deviation of the three-dimensional model size of the target object is less than 5%.The overall accuracy is high,and it has good application and promotion value.
