Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown in the present invention, a rockfill rolling scheme adjustment method based on particle grading and material composition visual recognition technology, figure 2 It is a schematic diagram of system operation, and its working process is described as follows:
[0028] (1) Create a rockfill material characteristic pattern library to provide library sources for subsequent image matching. It is mainly divided into two processes, namely the establishment of the initial pattern library based on finite samples and the expansion of the pattern library based on the Monte Carlo method:
[0029] ① Establishment of an initial pattern library based on limited samples: Taking rockfill materials randomly distributed in a typical construction site as initial samples, the color features of the particles in the image are extracted using the color histog...

The invention discloses a method for adjusting a rockfill rolling scheme based on particle gradation and material composition visual recognition technology. The steps are: 1. Create a rockfill material characteristic model library: establish the color, texture distribution, and crack of particles in a sample image The corresponding relationship between the size and other characteristics and the lithology category and weathering degree of the rockfill material provides a library source for subsequent image matching; 2. Image acquisition: take pictures of the rockfill material to be rolled and collect images; 3. Image recognition and pattern Matching: Digitally process the collected images, calculate the material gradation according to the gray value of the particle area of different sizes; then extract the material characteristics, and determine the characteristics of the lithology and weathering degree of the material by matching with the pattern library; 4. Image recognition The transformation of the results and the recommended plan of rolling: first build the rolling plan library, and then according to the image recognition and pattern matching results, and compare with the rolling plan library, the rolling plan is corrected and adjusted. The invention can adjust the rolling plan to avoid undervoltage phenomenon.
Description
technical field [0001] The invention belongs to the technical field of rockfill dam filling and rolling, and in particular relates to a method for adjusting a rockfill rolling scheme based on particle gradation and material composition visual recognition technology. Background technique [0002] The concrete face rockfill dam scheme is a commonly used dam type for the upper reservoir of the pumped storage power station. Since the compaction effect of the rockfill body is the key factor to control the settlement deformation of the dam body and prevent cracks in the face plate, how to ensure the rolling quality during the filling process is an important technical issue of the entire project. At present, the rolling process of rockfill dams is mostly based on the requirements of the "Code for Construction of Rolled Earth-rock Dams". Before the filling construction, the on-site rockfill rolling test is carried out to determine the corresponding dam body rolling parameters. Once...
