Earthwork Calculation Based on UAV Oblique Photogrammetric Technology and GEOPAK DTM Method

准确快速量算土方量对水利、建筑等各项工程规划设计和施工具有重要意义。为了实现土方量准确快速计算并降低外业成本,提出了一种集成无人机倾斜摄影测量技术与GEOPAK DTM的土方量计算方法。以嘉兴市北部湖荡及河湖连通工程为例,通过该方法实现工程区弃土堆场土方量计算。利用传统GPS-RTK技术得到的土方量与本文方法计算结果进行对比分析,以验证本方法的有效性。结果表明,集成无人机倾斜摄影测量技术与GEOPAK DTM进行土方量计算,在一定程度上优化了土方量计算流程,具有一定的参考价值。

Accurate and rapid earthwork calculation is of great significance to the planning, design and construction of water conservancy, construction and other projects. In order to achieve accurate and rapid earthwork calculation and reduce field costs, this paper proposes an earthwork calculation method that integrates UVA oblique photogrammetric technology and GEOPAK DTM. This paper takes the lake and river-lake connection project in the northern part of Jiaxing city as an example, the earthwork calculate of the spoil dump in the project area is realized by this method. In order to verify the effectiveness of this method, the earthwork volume obtained by traditional GPS-RTK technology is compared with the calculation results of this method. The results show that the integration of UAV oblique photogrammetric technology and GEOPAK DTM for earthwork calculation optimizes the earthwork calculation process to a certain extent, and has certain reference value.
