三维激光扫描与贴近摄影测量技术在边坡防护网计量对比分析
Metrology of Slope Protection Networks based on 3D Laser Scanning and Nap-of-the-Object Photogrammetry Techniques
摘要
Abstract
In order to solve the problems of poor accuracy,low efficiency and high security risk of the traditional manual statistical method,the three-dimensional laser scanning and Nap-of-the-Object Photogrammetry technology are adopted respectively.The slope protection pro-ject of hydropower station is taken as the study object.The processes and methods of data collection,data processing and engineering quantity statistics are studied,and the accuracy,work efficiency and safety of engineering quantity statistics are compared and analyzed.The results show that:the application of 3D laser scanning technology saves 26 h and improves the working efficiency by 87%;the application of Nap-of-the-Object Photogrammetry technology saves 25.5 h and improves the working efficiency by 85%;Nap-of-the-Object Photogrammetry technology is able to obtain the 3D model of slope with millimeter resolution,and the accuracy of the protection network identification and sta-tistics can reach 100%.Both methods can meet the needs of accurate,efficient and safe engineering measurement,effectively avoid the risks of manual operation,greatly improve the work efficiency,and have a guiding effect on similar projects.关键词
