一种基于航摄三维影像数据的工程量测算方法

本发明公开了一种基于航摄三维影像数据的工程量测算方法，包括如下步骤：在挖方区域及填方区域的边界上分别均匀布设若干个第一标记点及若干个第二标记点；获取工区施工前后在各个第一标记点围成的第一边界和各个第二标记点围成的第二边界范围内的DEM与DOM数据；导入Civil 3D软件中，计算施工工作量。本发明提出的技术方案的有益效果是：通过在工区范围内的挖方区域及填方区域的边界上分别均匀布设若干个第一标记点及若干个第二标记点，从而在生成DEM与DOM数据过程中，可忽略非施工区域，同时，也省去了现有的方法中需要通过比较施工前后的DEM数据来获得挖方区域及填方区域范围的步骤，从而大大提高了工程量测算速度以及工程量测算精度。 The invention discloses an engineering workload measuring and calculating method based on aerial photography three-dimensional image data. The engineering workload measuring and calculating method comprises the following steps of: evenly distributing a plurality of first mark points and a plurality of second mark points on the boundary of an excavation area and the boundary of a filling area respectively; acquiring DEM and DOM data in a first boundary defined by the first mark points and a second boundary defined by the second mark points before and after construction of a work area; and importing the data into Civil 3D software, and calculating the construction workload.
