The distance between the lifting plate 402 and the bottom of the detection box 3 is adjusted according to the width of the cloth, so that the collection ranges of the first collection camera 301 and the second collection camera 302 are matched with the width of the cloth. For example, the width of the cloth is 1m, and then the distance between the lifting plate 402 and the bottom of the detection image is 1.5m, so that the first acquisition camera 301 and the second acquisition camera 302 can acquire all the first image information and the second image information within the width range of the cloth.

In some embodiments, referring to fig. 2, the detection box 3 further includes a second chamber 32, where the second chamber 32 is located above the first chamber 31, and the first chamber 31 is provided with an identification terminal 321, and the identification terminal 321 is connected to the first acquisition camera 301 and the second acquisition camera 302, for identifying flaws in the first image information and the second image information. Whether or not a flaw exists therein is determined by directly recognizing the first image information and the second image information by the recognition terminal 321.

In some embodiments, the identification terminal 321 may include an image preprocessing module, a feature extraction module, a flaw identification module and an alarm module, where the image preprocessing module is used to preprocess the collected first image information and the collected second image information, the preprocessing process may be that the first image information and the second image information are converted into a single-channel image, then the feature extraction module is used to perform feature extraction on the preprocessed first image information and the preprocessed second image information, a distinguishing feature in a reference image is extracted, then the flaw identification module is used to identify the distinguishing feature, and the distinguishing feature is compared with stored flaw information to determine whether the distinguishing feature is the same as the flaw information, if the distinguishing feature is the flaw existing on the piece of cloth, if the distinguishing feature is different, then further determining that the distinguishing feature is a new flaw type or that the distinguishing feature is not the flaw existing on the piece of cloth.

It should be noted that the reference image is preset flaw-free cloth image information, and the flaw information is a preset relevant feature of the existing flaw type.

In some embodiments, the identification terminal 321 further includes a marking module, where the marking module may be an ultraviolet marking device, and when detecting that a flaw exists on the cloth, the marking module marks the position of the flaw, and then uniformly repairs the flaw.

In some embodiments, referring to fig. 2 and fig. 5, a fifth guide roller 501 is provided at a feed inlet 311 of the detection box 3, a driving wheel 502 is fixedly provided at one end of the fifth guide roller 501, a driven wheel 503 is rotatably provided between the fifth guide roller 501 and the first detection area, a fan 504 is fixedly connected to the driven wheel 503, and the driving wheel 502 and the driven wheel 503 are connected by a conveyor belt. In the production process of cloth or in the transmission process of cloth, tiny dust existing on cloth enters into the first image information and the second image information through the collection of the first collection camera 301 and the second collection camera 302, the dust is not flaws existing in the cloth, dust information exists in the first image information and the second image information due to the existence of the dust, whether the dust information is flaws or not cannot be determined by the identification terminal 321, and uncertainty of flaw detection is increased. The driving wheel 502 is driven to rotate in the process of conveying the cloth through the fifth guide roller 501, so that the fan 504 on the driven wheel 503 runs, fine dust on the cloth is removed, and the influence of the dust on the cloth on a flaw detection result is reduced.

In some embodiments, the detection box 3 is provided with magnetic means on a side opposite to the fan 504. It will be appreciated that the fine dust is charged, and the fan 504 blows the fine dust off the cloth and at the same time, the magnetic device is used to absorb the dust, so as to prevent the dust from falling onto the cloth again.

In some embodiments, the radius of the primary wheel 502 is greater than the radius of the secondary wheel 503. By the radius of the driving wheel 502 being larger than that of the driven wheel 503, the rotation speed of the driven wheel 503 is larger, the rotation speed of the fan 504 is further larger, and the generated wind force is larger, so that the effect of cleaning fine dust on cloth is better.
