Problems solved by technology
The identification of female and male silkworm cocoons by near-infrared spectroscopy requires pretreatment of silkworm cocoons, and the detection accuracy of near-infrared spectroscopy is closely related to ambient temperature, humidity, and the distance between the detector and the sample. These environmental conditions are difficult to guarantee in practical applications
Based on magnetic resonance imaging (MRI) technology, male and female silkworm cocoons can be successfully distinguished without damage, but the experimental equipment is expensive and it is difficult to achieve online detection

The invention provides a device and method for automatically discriminating cocoon sexuality. The device is characterized in that a feeding device and a weight detecting device are arranged above a conveyor belt on the left; X-ray detecting devices are arranged above and below the conveyor belt; a sorting device is arranged at the right side of the conveyor belt; and the feeding device comprises a feeding plate and a plurality of feeding baffles arranged on the feeding plate in parallel at intervals. The method comprises the following steps: adopting a computer to control an X-ray detector toobtain the original X-ray image of the silkworm chrysalis; and taking the six characteristic parameters including five image characteristics of the silkworm chrysalis and the cocoon weight as the characteristic parameters of cocoon sexuality, establishing a discrimination model of the characteristic parameters of cocoon sexuality and cocoon sexuality by a K-means clustering method according to anartificial discrimination model established in advance and importing the model into cocoon sexuality discriminating software to discriminate the cocoon sexuality, wherein the five image characteristics of the silkworm chrysalis include area, perimeter, long axis, minor axis and mean brightness of the image of the silkworm chrysalis. The device and the method have the following beneficial effects:the device has simple structure and automatically discriminates cocoon sexuality on line, without damaging the cocoons; the discrimination speed is high; and the discrimination result is accurate.
Description
technical field [0001] The present invention relates to a method for automatically discriminating sex of cocoons, in particular to a method and device for automatically discriminating sex of silkworm cocoons by combining weight detection technology, X-ray imaging technology and digital image processing technology, which are used for computer automatic discrimination and sorting of cocoon sex . Background technique [0002] Silkworm cocoons are divided into male and female. Compared with female silkworm silk of the same silkworm species, the male silkworm silk has finer cocoon silk fineness, excellent clarity, good cohesion, high raw silk grade, good fabric elasticity, and the fabric silk surface is flat, smooth and waxy. It is an ideal raw material for reeling 5A and 6A high-grade raw silk due to its thick handle. The current silk reeling technology mostly adopts the method of mixing male and female cocoons, which can only reel male and female composite silk, and it is diff...
