Abstract

The invention discloses an image acquisition system for detecting flaws of textiles. The image acquisition system comprises a mini-type camera assembly which is located just above a conveying direction of a textile to be subjected to flaw detection, wherein light-supplementing light source assemblies, which are distributed at equal intervals, are arranged at the peripheral side of the mini-type camera assembly; the mini-type camera assembly is clamped in a reserved region in the middles of the light-supplementing light source assemblies; a light-shielding cover assembly is fixed in the photographing direction of the mini-type camera assembly; the light-shielding cover assembly downward extends out of a plane of the light-supplementing light source assemblies from the reserved region. The image acquisition system disclosed by the invention is used for effectively shielding impure light and the signal to noise ratio is improved by 14dB; the mini-type camera assembly has a good heat dissipation effect and high working stability; a self projection of the detected textile is reduced to the minimum through the light-supplementing light source assemblies; the residual self projection of the textile is not expressed in a digital image, and a more accurate and reliable digital image data source is provided for an image recognition technology; the recognition confidence degree reaches industrial application standards; the image acquisition system is ingenious in concept and novel in structure and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of textile defect detection, in particular to an image acquisition system for textile defect detection. Background technique [0002] Traditional textile defect detection mainly relies on manual work, and less automatic detection methods are used. With the rapid advancement of science and technology, the automatic detection of textile defects has also developed rapidly. At present, in terms of digital image acquisition, the existing automatic detection of textile defects mainly uses industrial cameras or micro-lenses of integrated single-chip sensors for photoelectric conversion. Usually, no special technical measures are adopted for the improvement of the digital image acquisition environment, resulting in The quality of the digital image is low, and it mainly relies on image recognition technology to complete the detection. Therefore, there are the following disadvantages, as follows: [0003] (1) Due to...
