Method for calculating excavation amount of complex-form soil material field

Abstract

The invention discloses a method for calculating the excavation amount of a complex-form soil material field, which comprises the following steps of (1) setting a plurality of scanning stations according to the topographic condition of an excavation surface of the soil material field and the size of the excavation surface, and scanning the forms of the excavation surface before and after excavation of an excavation area of the soil material field; (2) carrying out point cloud registration on the coordinate system of the point cloud data obtained by scanning so as to convert the coordinates of the point cloud data into the same coordinate system; (3) analyzing the registered data, establishing a point cloud data compression method based on a hypergeometric space sphere, and performing the bidirectional compression on the registered point cloud data to reduce the data redundancy; (4) extracting the internal data of the excavation area from the compressed data, and deleting the data outside the excavation area; and (5) according to the extracted point cloud data before and after the excavation of the excavation area, calculating the excavation square amount of the soil material field. By means of the method, the efficient processing of the point cloud data of the excavation face of the complex-form soil material field and the rapid and accurate metering of the excavation square amount of the material field are achieved.

Description

technical field [0001] The invention relates to a method for calculating the excavation volume of a soil material field, in particular to a calculation method for the excavation volume of a soil material field with complex shapes. Background technique [0002] Core rockfill dams have been widely used in hydropower engineering construction in recent years because of their good foundation adaptability, local materials, good structural stability, and simple anti-seepage structure. The core wall is the core part of the anti-seepage of the dam body, and it has strict requirements on the quality of anti-seepage soil materials. For extra-high core wall dams, the demand for anti-seepage soil materials is huge, and multiple stockyards are usually required to coordinate the supply of materials. The mining volume of the soil stockyard is a key indicator of project progress and cost control. During the mining process of the stockyard, it is necessary to accurately record the mining volu...
