Abstract
An automatic sex judging system for chickens with one day age is composed of feeding unit, delivery unit, lighting system, CCD camera, software system, control system, and classifying unit. After the image information is aquired by CCD camera and image data acquisition card, it is processed by filter, threshold, pattern recognizing and analysis. All the chickens are classified into male, female and indeterminate classes according to the analyzed results. Its advantages are reducing judging cost and improving working conditions.
Description
Technical field
The present invention relates to aviculture, is a kind of chick sex automation discrimination method and system.
Background technology
It is important production link in the poultry husbandry that the chick sex is differentiated.Existing chick sex discrimination method all is artificial discrimination methods, mainly contains apparatus differential method, profile method, anal identification method and sex-linked inheritance method.To discriminating personnel's specification requirement height, and labour intensity is big, and identification efficiency is low, the cost height.The automation of chick sex differentiates it is the medium-term and long-term difficult problem that exists of domestic and international poultry husbandry, lacks method that the automation of chick sex differentiates and has hindered the hive off enforcement of feeding manner of male and female in the poultry husbandry.Years of researches show, realize that it is to shorten feeding period, reduce the raise chickens important technique measure of economic benefit of feedstuff-meat ratio and raising that hiving off of cock and hen raises, but also can improve female young survival rate and reduce interindividual variation, improve uniformity, be convenient to mechanization and butcher processing, improve the productivity ratio and the specification level of product.
Abroad for the existing research of method that utilizes Vision Builder for Automated Inspection identification chick sex.For example, United States Patent (USP) Pub.No.2001/0035370 A1 and No.6,396,938 B1 utilize the flight plumage speed ratio juris of sex-linked inheritance method, discern the length difference of chick assistant by the machine vision image and differentiate sex.And for the plumage speed ratio juris of utilizing the sex-linked inheritance method, discern the difference of chick color characteristic by machine vision machine vision image and come the research of distinctive Chinese alligator to yet there are no report.
Summary of the invention
The purpose of this invention is to provide a kind of chick sex automation discrimination method and system.
The technical solution used in the present invention is as follows:
One, discrimination method:
1) feeding chick: chick is fed to conveyer belt by intake mechanism;
2) carry chick: carry chick to lighting box;
3) obtain the chick image:, obtain the chick image information by ccd video camera and image data acquiring card;
4) handle image: image information is carried out filtering and eliminating noise, greyscale transformation, thresholding processing by software systems;
5) pattern-recognition: the number of pixels according to gray scale is discerned;
6) gender-disaggregated: under the control of control system, the result classifies chick according to pattern-recognition by sorting mechanism.
Two, identification system:
It comprises intake mechanism, lighting box, CCD camera, sensor, control cabinet, PC, sorting mechanism, transport tape, driving wheel, vibrating mechanism; Energy swing under the intake mechanism, be connected to by driving wheel and drive the transport tape that gradient is arranged that rotates, under the transport tape on top one side vibrating mechanism is housed, lighting box is housed above transport tape, and lighting box is equipped with CCD camera and sensor in the lighting box, one termination PC of CCD camera, the other end connects PC behind control cabinet, sensor connects PC behind control cabinet, is connected to sorting mechanism on the other end of transport tape.
Advantage of the present invention is: it provides realization chick sex automation discrimination method and system, be used for realizing the sex automation discriminating of a Japanese instar chickling, replace existing artificial discrimination method, can raise labour productivity, reduce and differentiate cost and improve working conditions, for male and female in the poultry husbandry hive off the enforcement of feeding manner provide before topic ensure.

Embodiment
As shown in Figure 1, the step of chick sex automation discrimination method is as follows:
1) feeding chick 1: chick is fed to conveyer belt by intake mechanism;
2) carry chick 2: carry chick to lighting box;
3) obtain chick image 3:, obtain the chick image information by ccd video camera and image data acquiring card;
4) handle image 4: image information is carried out filtering and eliminating noise, greyscale transformation, thresholding processing by software systems;
5) pattern-recognition 5: the number of pixels according to gray scale is discerned;
6) gender-disaggregated 6: under the control of control system, the result classifies chick according to pattern-recognition by sorting mechanism.
As shown in Figure 2, chick sex automation identification system, it comprises intake mechanism 7, lighting box 9, CCD camera 10, sensor 11, control cabinet 12, PC 13, sorting mechanism 14, transport tape 15, driving wheel 16, vibrating mechanism 17; Can swing intake mechanism 7 times, be connected to by driving wheel 16 and drive the transport tape that gradient is arranged 15 that rotates, vibrating mechanism 17 is housed under the transport tape on top one side, lighting box 9 is housed above transport tape 15, and lighting box 9 is equipped with CCD camera 10 and sensor 11 in the lighting box 9, one termination PC 13 of CCD camera 10, the other end connects PC 13 behind control cabinet 12, sensor 11 connects PC 13 behind control cabinet 12, be connected to sorting mechanism 14 on the other end of transport tape 15.
Its workflow is: adorn every chick 8 by intake mechanism 7 and separate from colony, drive the transport tape 15 that rotates by driving wheel 16 chick 8 is delivered to lighting box 9, guarantee the stable of chick 8 by the vibration of transport tape 15 and vibrating mechanism 17, handle and PRS by CCD camera 10, sensor 11, control cabinet 12 is formed and PC 13 is formed image, and finish through greyscale transform process.
As shown in Figure 3, control cabinet 12 comprises compositions such as 89C52 single-chip microcomputer, communication translation interface, photoelectricity isolation.When transport tape 15 is delivered to the correct position of lighting box 9 with chick 8, sensor 11 is sent signal into single-chip microcomputer, Single-chip Controlling CCD camera 10 is made a video recording, notifying PC 13 to carry out image simultaneously handles and pattern-recognition, PC 13 recognition results are sent single-chip microcomputer back to, single-chip microcomputer output control signal is given sorting mechanism, classifies.
Be illustrated in figure 4 as the male chicken image; Be illustrated in figure 5 as female chick image.Because there are tangible gray difference in male chicken and female chick image.The ash that the gray scale of female chick image is higher than the male chicken image fills, and gray difference then is the foundation that sex is differentiated, again by sorting mechanism 14 under the control of control system, according to the pattern-recognition result, chick is divided into different classes of.
As Fig. 6, shown in Figure 7, be the embodiment that pattern-recognition is adopted in the inventive method, Fig. 6 is the male chicken image of thresholding, Fig. 7 is female chick image of thresholding.
The number of pixels of said gray scale is discerned, and promptly P is the number of pixels of certain gray scale, then judges that by P the chick sex is as follows:
Wherein: P
mBe lower threshold value, P
fBe upper threshold value.
