Embodiment Construction

[0071] Such as figure 1 As shown, a hole defect detection method of a large circular knitting machine related to the present invention is implemented on the following hardware carriers: high-quality image acquisition equipment, a control terminal and a large circular knitting machine. The camera and light source are integrated into an image acquisition device and installed inside the circular knitting machine. The camera captures the fabric image and feeds it back to the control terminal for fabric defect detection. The fabric image is processed and judged by the following detection methods in the control terminal.

[0072] Such as figure 2 As shown, a method for detecting hole defects of a large circular knitting machine disclosed by the present invention includes:

[0073] Step 1. Data collection

[0074] Through the image acquisition device installed in the circular knitting machine, the fabric image is collected in real time, and the fabric image is uploaded to the cont...

Abstract

A hole defect detection method for circular knitting machines of the present invention uses machine learning methods to detect fabric holes and defects, preprocesses defect images according to adaptive image enhancement technology, effectively segments areas of interest, and uses corner detectors to Combined with the sorting method, the monotonic illumination and rotation-invariant feature information of fabric defects are effectively extracted; in terms of fabric defect point matching, the two-way matching method is used to successfully obtain knitting hole needle defects. The invention greatly improves the speed and efficiency of defect detection of textiles.

Description

technical field [0001] The invention relates to a visual detection method, which is suitable for real-time detection of cloth of textile equipment, in particular to a method for detection of holes and defects of large circular knitting machines. Background technique [0002] The research on automatic detection of fabric defects in my country has not yet had a mature commercial application of automatic detection system for fabrics. The research on defect recognition is still mainly in the theoretical stage. In this regard, the domestic fabric automatic detection system needs to be developed towards practicality and commercialization. There are many types of fabric defects such as holes, broken frames, weft shrinkage, etc., which cause huge problems for factories to produce high-quality fabrics. For this reason, the present inventor has developed a feasible fabric defect detection method to improve the production efficiency and quality of the fabric. Contents of the invent...
