摘要
老旧小区的改造提升是切实关系到民生福祉的重要工程,在旧城改造中高效、精准地采集目标建筑物空间数据对工程造价核算、规划设计等都具有重要意义。常见的三维激光扫描及倾斜摄影测量技术受扫描视角及影像畸变等影响均存在一定局限性。本文将移动式三维激光扫描仪获取的点云数据和低空倾斜摄影测量生成的点云数据进行融合,研究结果表明,本文提出的综合测量法绘制的立面成果图精度提升明显,且效率与传统全站仪法相比具有较高的优越性,对提升旧城改造工程质量具有一定参考价值。
The renovation and improvement of old residential areas is an important project related to people's well-being.In the reno-vation of old cities,efficient and accurate collection of spatial data of target buildings is of great significance for project cost account-ing,planning and design.Common 3D laser scanning and oblique photogrammetry techniques have some limitations due to the scan-ning angle and image distortion.In this paper,the point cloud data obtained by the mobile three-dimensional laser scanner and the point cloud data generated by the low-altitude oblique photogrammetry were fused.The research results show that the accuracy of the facade result map drawn by the comprehensive measurement method proposed in this paper is significantly improved,and the efficiency is still higher than that of the traditional total station method,which has a certain reference value for improving the quality of the old city renovation project.
