The invention discloses a sampling determination method for a cemented sand gravel yard. The method comprises the following steps: acquiring an aggregate image of the cemented sand gravel yard; dividing the preprocessed aggregate image into a plurality of sub-images, and segmenting a contour image of each aggregate in each sub-image; carrying out aggregate grading identification on the contour image by adopting a BP neural network model; and according to the identification result, determining whether one sampling point or two sampling points are set in each sub-image. Compared with random sampling points in the prior art, the method for determining the sampling points in the scheme has the advantages that reflected information is relatively complete, the aggregate of the corresponding sub-image can be specifically selected for damming according to needs in actual engineering, and the sampling points do not need to be determined in a large range in a time-consuming and labor-consuming manner.
Description
technical field [0001] The invention relates to a cemented dam aggregate detection technology, in particular to a method for determining a sampling point of a cemented sand and gravel stockyard. Background technique [0002] The cemented dam is made of natural river bed gravel material, bedrock and slope excavation material, artificial crushed material and other local materials that are not screened or washed in the engineering site, and are cemented with a small amount of cement, fly ash and admixtures New dam types for dams made of materials with high strength, shear and erosion resistance. The planning and selection of the cemented sand and gravel stockyard is an important link in the construction organization design of the cemented dam. During the construction process, there is a large demand for aggregates. The raw materials for cemented dams account for the largest proportion of raw materials for dam construction. The aggregate sampling point selection The range of ag...
