Application and accuracy analysis of P4-RTK in irregular deposit volume calculation

摘要: 针对生产企业内的一些体积庞大且不便于近距离实测的不规则堆体体积量算问题,本文利用大疆精灵P4-RTK无人机对某生产企业内的一大型不规则建筑废料堆积体进行高精度影像数据获取,同时使用GNSS-RTK测量部分堆积体表面离散点坐标．利用所获取的高精度影像数据,解算出该堆积体表面的的点云、DEM、DOM等数据以及三维模型,最后对堆积体进行体积量算．与用GNSS-RTK测得的离散三维坐标点采用DTM法计算的堆体体积的结果对比证明,基于P4-RTK无人机免像控技术量算不规则堆体体积能满足实际生产的要求．Abstract: Aiming at the volumetric calculation of irregular deposit in the production enterprises, this paper uses the Dajiang P4-RTK drone to carry out a large irregular construction waste deposit in a production enterprise based on the high-precision image data acquisition. Meanwhile, GNSS-RTK had been used to measure the discrete point coordinates of the deposits surface. Using the acquired high-precision image data, the point cloud, DEM, DOM and the 3D model of the surface of the deposit are calculated. Finally, the deposit volumetric had been calculated. Compared with the results of the volume calculation of the discrete three-dimensional coordinate points measured by GNSS-RTK using the DTM method, the P4-RTK unmanned aerial vehicle-free image control technology can be used to calculate the irregular stack. And the volume can meet the requirements of actual production.
