3D激光扫描作为一种新兴的测绘工具,近几年也开始被引入到水土流失侵蚀监测中。将3D激光扫描仪应用于典型的点状、线状建设项目中水土流失量的监测,同期开展常规钢钎监测比对,结果表明:与传统钢钎法相比,3D激光扫描法在点状和线状工程中的平均相对误差分别为11.15%和8.25%,且3D激光扫描法更能全面而直观地反映水土流失发生发展过程,测量精度也更高,在建设项目水土流失量的监测上适应性良好。
As an emerging mapping tool, 3D laser scanning has also been introduced into soil and water erosion monitoring in recent years. The application of 3D laser scanner to the monitoring of soil and water loss in a typical spot-shaped and linear construction project and the monitoring and comparison of conventional brazing steel over the same period showed that compared with the traditional steel brazing method, The average relative errors in linear engineering are 11.15% and 8.25%, respectively, and the 3D laser scanning method can comprehensively and directly reflect the occurrence and development of soil erosion and improve the accuracy of measurement. The 3D laser scanning method adapts to the monitoring of soil and water loss in construction projects Good sex.
