The invention discloses an air-ground integrated detection method for a wide-grading mixed aggregate, and provides an aggregate rapid intelligent detection segmentation algorithm Aggregate Net model based on an instance segmentation framework based on a deep learning method and a laser radar measurement technology under a big data background, the model has strong parallel target detection and instance segmentation capabilities, can obtain the predicted long diameter, the predicted short diameter and the aggregate particle size of each aggregate, and the thickness of the aggregate is obtained by a laser radar measurement technology, so that the equivalent volume of each aggregate is accurately calculated, and finally, the equivalent volume is subjected to data fitting with a manual sampling and screening result, so that a grading curve result with higher precision is obtained.
Description
technical field [0001] The invention relates to the technical field of aggregate detection, in particular to a wide-gradation mixed aggregate open-ground integrated gradation detection method. Background technique [0002] Construction projects and water conservancy projects are important infrastructures for my country's national economic construction and social development, and it is imperative to comprehensively improve their safety. Various wide-graded mixed aggregates are the main building materials for water conservancy, highway, railway and construction projects. A reasonable aggregate mix ratio is an important factor affecting the durability of engineering structures and ensuring the safety of engineering operations. In order to ensure the compaction quality of the filling project and improve the anti-deformation and anti-permeability performance, it is particularly important to use fillers with reasonable gradation. Among them, the volume ratio of aggregate in conc...
