摘要
近年来,低空无人机在测绘领域得到广泛应用,准确、快速地获得土石方量对工程建设具有重要意义。本文主要介绍了无人机航摄采集三维点云数据成图进行土石方量计算的方法,并以深江产业园建设过程中的土石方测量为实例进行试验。研究表明,利用无人机航摄成图比传统的全站仪、GPS测图有明显的优势;与传统方法相比,无人机航摄方法大大减少了人工工作量和劳动强度;在精度指标相同的情况下,无人机航摄方法单位面积数据量远超传统方法,工作效率大幅提升。
In recent years, low altitude unmanned aerial vehicle(UAV) has been widely used in the field of surveying and mapping, Accurate and rapid acquisition of earthwork volume is of great significance to engineering construction. This paper mainly introduces the method of earthwork volume calculation by UAV aerial photography collecting three-dimensional point cloud data mapping. Taking the earthwork measurement during the construction of Shenjiang Industrial Park as an example, the research shows that UAV aerial mapping has obvious advantages over traditional total station and GPS mapping. The case results show that compared with the traditional UAV aerial photography method, the manual workload and labor intensity are greatly reduced. At the same time, when the accuracy index is almost the same as that of the traditional method, the amount of data per unit area is far greater than that of the latter, and the work efficiency is greatly improved.
