Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] refer to Figures 1 to 3 As shown, the present invention provides a method for detecting burrs of circular injection molded parts, comprising the following steps:

[0032] S1: Collect image information of the product and preprocess it;

[0033] S2: Based on the image information preprocessed in S1, perform threshold segmentation processing on it to obtain the image information of the circular target area;

[0034] S3: Based on the image information of the circular target area obtained in S2, determine the shapes and positions of some burr contours around the circular target area;

[0035] S4: Extract the contour feature information of each burr and output and save it.

[0036] Wherein, said S1 includes the following steps:

[0037] S11: Obtain the image information of the product through the camera;

[0038] S12: Based on the prod...

Abstract

The invention discloses a method for detecting burrs of a circular injection molded part. The method comprises the following steps: S1, collecting image information of a product and preprocessing the image information; S2, based on the image information preprocessed in the S1, performing threshold segmentation processing on the image information to obtain image information of a circular target area; S3, on the basis of the image information of the circular target area obtained in the S2, determining the shapes and positions of a plurality of rough edge contours on the peripheral side of the circular target area; and S4, extracting contour feature information of each burr, and outputting and storing the contour feature information. Firstly, collected product image information is preprocessed to enhance image quality, then, threshold segmentation is performed on a target feature region of the product image information, then, the shape and the position of a burr are determined through a region morphology detection method and a sub-pixel edge detection method, and finally, the burr is extracted, output and stored. The invention can quickly extra blurr. Therefore, a large amount of human resources can be saved, the detection efficiency is high, and the detection precision is high.

Description

technical field [0001] The invention relates to the technical field of product burr detection, in particular to a method for detecting burrs of circular injection molded parts. Background technique [0002] With the improvement of plastic production and the continuous expansion of application fields, higher requirements are put forward for the quality of plastic molds. After that, determine the size of the blemish and its location on the side. At present, manual detection is basically used for the detection of defects such as burrs and dents, which requires a lot of labor, high detection cost, and low detection rate. Contents of the invention [0003] The purpose of the present invention is to provide a method for detecting the burr of a circular injection molded part. The method first collects the image information of the product through a camera, and performs grayscale transformation and filtering and denoising processing on it to enhance the image quality. area, based...
