Problems solved by technology

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a glass defect type identification method, which uses the image segmentation threshold obtained in the adaptive threshold selection mode to separate the glass from the image background, and uses a combination of median filtering and mean filtering In order to maintain image details while removing Gaussian noise, more importantly, select the circularity and elongation of the defect target as the benchmark for defect type determination, so as to identify various glass defect types more effectively

Embodiment Construction

[0014] The implementation of the glass defect type identification system of the present invention will be described in detail below with reference to the drawings.

[0015] Glass is one of the important materials in the industrial and civil fields, and the existence of defects directly determines the quality of construction. For glass manufacturers, how to find glass defects in time and determine the types of glass defects is very important.

[0016] In the prior art, the detection of glass defect types lacks pertinence. Especially for solutions using image detection technology, there are generally problems of improper selection of segmentation thresholds, filtering techniques and defect features, which seriously affect the recognition effect.

[0017] In order to overcome the above-mentioned shortcomings, the present invention builds a glass defect type identification system, according to the image characteristics of glass and glass defects, targeted selection of appropriate segment...

Abstract

The present invention relates to a glass defect type identification method. The method comprises: 1) providing a glass defect type identification system, wherein the identification system comprises a glass holding platform, an image collecting device, a defect image detection device and an embedded processing device; the glass holding platform is used for placing a to-be-tested glass monoblock; the image collecting device is used for collecting glass images of the to-be-tested glass monoblock; the defect image detection device is used for determining a defect image among the glass images; and the embedded processing device is connected with the defect image detection device, and determines a glass defect type based on the defect image; and 2) using the identification system to perform identification. According to the method provided by the present invention, different defect detection parameters can be determined according to different glass types, so that the accuracy of glass defect type identification is improved.

Description

Technical field [0001] The invention relates to the field of glass inspection, in particular to a method for identifying glass defect types. Background technique [0002] The existing glass defect type recognition technology has the following defects: (1) The threshold value in the glass recognition mode based on image segmentation is improperly selected, which affects the recognition effect of subsequent defect types; (2) The selection of image filtering technology is difficult, and a single filtering technology is generally used. Unable to filter out various image interference; (3) The characteristics of glass defects cannot be determined, which makes it difficult to identify the types of glass defects. [0003] To this end, the present invention proposes a glass defect type identification method, which can select a suitable image segmentation threshold, effectively separate the glass in the image from the background, can remove various image interference, and can determine the b...
