Abstract

The invention provides a mesh fabrics screen length deviation rate detection system based on machine vision. The system comprises an industrial personal computer, a display, a light source, an image acquisition card, an adjustable image acquisition device and an alarm. The adjustable image acquisition device comprises a CCD industrial camera and a mobile device. A network to be detected is arranged between the CCD industrial camera and the light source. The CCD industrial camera is electrically connected with the industrial personal computer through the image acquisition card. The display and the alarm are respectively communicated with the industrial personal computer. The real-time screen image of the CCD industrial camera is transmitted to the industrial personal computer. The industrial personal computer uses a feature extraction method based on coordinates to process an acquired image, and at the same time calculates the length deviation rate of each screen to acquire the extreme value of the deviation rate. Whether a result is within a set deviation rate range is judged. If the result is beyond the set range, the alarm is switched on. According to the invention, manual measurement is replaced; the worker's labor intensity and the missed inspection rate are reduced; and the degree of automation of a netting process is improved.

Description

technical field [0001] The invention relates to a detection system, in particular to a detection system for the mesh length deviation rate of mesh fabric based on machine vision. Background technique [0002] Mesh fabric refers to the fabric with certain regular meshes in the fabric structure. It has been used in many fields such as automobile, medical treatment, hygiene, sports and leisure, filter cleaning, safety protection, aerospace and so on. However, as mesh fabrics are used more and more widely, people have higher and higher requirements for their surface quality. How to improve the quality of mesh fabrics and realize the automation of mesh fabric surface quality testing has become a constraint for its development. The key factor. The surface quality of mesh fabric is mainly determined by the mesh length deviation rate. For a long time, the measurement of the deviation rate of the mesh length is by manual measurement. However, this method has many disadvantages. Fi...
