Embodiment

[0069] Such as figure 1 Shown, the present embodiment a kind of ceramic tile grading color separation detection method, comprises the following steps:

[0070] S1. Obtain a tile image to be recognized; perform preprocessing on the tile image.

[0071] Preprocessing specifically includes the following steps:

[0072] S11. Perform grayscale transformation on the tile image to obtain an initial grayscale image; the range of grayscale values ​​can be set to 0-255;

[0073] The initial grayscale image obtained by the grayscale transformation of the tile image has the advantages of less memory usage, fast operation speed, and more convenient processing;

[0074] S12. Perform median filter processing on the initial grayscale image to obtain a filtered grayscale image to remove noise; the median filter processing template is preferably 3×3; after sorting the 9 pixels in the neighborhood, take the median value and use The median value replaces the pixel value in the center of the ke...

Abstract

The invention provides a ceramic tile grading and color separation detection method and device, a medium and equipment. The method comprises the following steps: acquiring a to-be-identified tile image; preprocessing the ceramic tile image; inputting the pre-processed ceramic tile image into a ceramic tile grading and color separation detection network model, and outputting a ceramic tile grade type by the ceramic tile grading and color separation detection network model; the ceramic tile grading and color separation detection network model is a ceramic tile grading and color separation detection network model obtained by training and testing an initial convolutional neural network model. The method comprises the following steps: performing grading and color separation detection on tiles based on a convolutional neural network model, and performing grade type division on the quality of the tiles; manpower resources can be saved and the detection efficiency can be improved; the operation speed is high, and response requirements of a high-speed production line can be met; the classification accuracy is high, and errors and mistakes existing in manual classification can be avoided.

Description

technical field [0001] The present invention relates to the technical field of ceramic tile detection, and more specifically, relates to a tile classification and color separation detection method, device, medium and equipment. Background technique [0002] With the development of the decoration industry, the demand for ceramic tiles is increasing day by day, and the quality requirements for ceramic tiles are also getting higher and higher. In the process of ceramic tile production, due to improper manufacturing process and collision caused by handling process, surface defects such as cracks, stains, scratches, pinholes, cavities and uneven colors and unqualified dimensions, uneven surface, and collapse of tiles will occur. Geometric defects such as edges. On-line grading and color separation inspection of the produced tiles is an important part of the tile manufacturing process to ensure the standard geometric size of the tiles, the integrity of the shape and the balance o...
