Method, system and device for locating edge-wrapped seams of panels

Abstract

The invention belongs to the technical field of image detection, and specifically relates to a method, system and device for locating edge-wrapped seams of plates, aiming to solve the problem that the edge-wrapped seams of plates cannot be automatically positioned by image detection methods in the prior art. The method of the invention includes: extracting the gradient feature map of the edge-wrapped seam image of the plate; dividing it into a plurality of sub-images and calculating the cumulative sum of the gradient amplitude values ​​of each pixel row as seam candidate samples; merging adjacent sub-images after clustering with the central value Sample; after clustering with the distance in the direction of the merged sample line less than the set threshold as the measure, fit the straight line with the set point; after clustering with the distance between the merged sample and the fitted straight line as the measure, fit the straight line again as the positioning sheet package Edge seams. The present invention combines the plate image acquisition orientation and the characteristics of the seam in the gradient map, extracts the longitudinal gradient feature map of the image, and performs multiple clustering through different measurement values, eliminates noise interference, and realizes rapid positioning of the plate edge seam , high accuracy.

Description

technical field [0001] The invention belongs to the technical field of image detection, and in particular relates to a method, a system and a device for locating edge-wrapped seams of boards. Background technique [0002] In recent years, consumers' demand for personalized furniture has become more and more prominent, so customized furniture has become more and more popular, and the customized furniture market has also developed vigorously. Usually, after the customer completes the finalization of the furniture, the factory produces panels of the required size and different designs and colors according to the shape and structure of the furniture. The internal material of the board is usually wood, wood fiber, fiber scraps, etc. Usually, the outer surface of the board will be attached with different textures. During the processing and production of the board, it is inevitable that the packing will fall off, bump, and glue, etc. Various non-conformities. Due to the inconveni...

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, the prior art cannot automatically locate the position of the edge seam of the plate through the image detection method, and thus cannot realize the automatic defect detection, the detection efficiency is low, and the error rate is high. The present invention provides Provided is a method for positioning seams of edge-wrapped panels, the positioning method comprising:
