摘要
提出一种利用无人机倾斜摄影测量技术进行土石方量计算的方法,首先通过无人机快速获取现场数据并进行三维建模,然后对模型数据进行一定的后处理,去除影响土方量计算的地物以及获取精准边界,最后对修饰后的三维模型进行土方量计算分析,获取最终的土方量计算结果。工程实践表明使用该方法可进行土方量的高精度自动量算,能提高土方量工程的效率,具有广泛的实用前景。
In this paper,we presented a calculation method of earthwork volume based on UAV oblique photogrammetry.Firstly,we used UAV to acquire the field data quickly,and carried out 3D modeling.Then,we post processed the model data to remove the ground objects that affected the calculation of earthwork volume,and obtained accurate boundaries.Finally,we calculated and analyzed the modified 3d model to obtain the final calculation result of earthwork volume.The engineering practice shows that this method can calculate the earthwork volume automatically with high precision,and improve the efficiency of earthwork volume engineering.
