Abstract
The invention describes a method for automatically controlling and selecting the bodies of slaughtered poultry. The invention aims at providing a very easy and cost-effective method for automatically controlling and selecting the bodies of slaughtered poultry. According to the invention, said aim is achieved in that the body of the slaughtered poultry to be controlled is selected by conducting color analysis of the light reflected from the visible surface parts, said light being detected as a diffuse color mixing light eliminating spatial contours using a measuring technique, wherein the measured value is used for selection as integrating value for the totality of visible surface parts.
Description
Method for Automatically Controlling and Selecting the Bodies of Slaughtered Poultry The invention describes a method for automatically controlling the bodies of slaughtered poultry which after slaughter, are transported past a control device by means of a conveyor device and are then selected by means of a triggered optical measurement that is a function of the control result.
In modern slaughterhouses, large quantities of poultry are slaughtered automatically. As a result, the assurance of quality control and the automatic selection and quality control that are required by this are of considerable significance. Only thus can it be assured that on the one hand, no unhealthy, damaged, or otherwise abnormal poultry reaches the market and on the other hand, the necessary product qualities for particular marketing paths can be presorted.
According to the International Patent Classification (IPC), the processing of slaughtered poultry bodies is classified in the class A22B 5/00.
The patent DE19619099 has disclosed the contact-free evaluation of slaughtered poultry bodies by means of image processing. In this connection, an optical image of the complete slaughtered poultry body is photographically evaluated and is adapted to models for parameter determination. In addition, there is a detection of defective regions of the poultry body such as differently colored image regions.
The disadvantage of this embodiment is the elaborate and cost-intensive photographic processing in order to detect the slaughtered poultry body or its body parts. The contour detection involves unnecessary error risks and decreases the reliability in the control of slaughtered poultry bodies.
Patent DE 196 37 234 A1 describes a process for on-line verification of the colour purity of structured or unstructured surfaces, The surfaces are captured by a video camera and the electronic signals received are evaluated by computer.
Simultaneously with the surfaces, color values of one or more patterned reference tables are captured, with the optical resolution of the capture devices set sufficiently low that the structure of the surfaces is not captured. The integral, specified color values of a surface are determined. Deviations of the specific, specified surface colours from a nominal/reference value can be used, for example, to grade the quality of textiles or of meat as well. The use of reference tables, the determination of image points of equal brightness for red, for green, and for blue, demand correspondingly high effort to perform a color comparison.
Simple and cost-effective selection of damaged or abnormal slaughter poultry is not possible with this process.
The object of the invention is to produce a very simple and inexpensive method for automatically controlling and selecting slaughtered poultry bodies.
The object is attained by means of the features disclosed in claim 1. Preferred modifications ensue from the dependent claims.

The object of the invention is to produce a very simple and inexpensive method for automatically controlling and selecting slaughtered poultry bodies.
The object is attained by means of the features disclosed in claim 1. Preferred modifications ensue from the dependent claims.
2 The essence of the invention lies in the color analysis of the mixed color light that is backscattered by the slaughtered poultry body to be controlled and is received by means of a color light sensor and the subsequent computer-executed evaluation of the color data for the required selection. Through the use of a diffuse mixed color light, all predetermined visible surface regions are detected simultaneously and can be evaluated by means of a color analysis. Consequently, the continuing image processing of an optical picture is eliminated. In this connection, the invention makes use of the knowledge that in slaughtered poultry bodies which are essentially alike, the reliable selection of very abnormal body regions such as breast, wing, and leg is of primary interest.
-2a-In a first variant, this mixed color light is generated without an optical image by means of the objectiveless reception of the diffusely backscattered light through a predetermined limiting aperture in front of the slaughtered poultry body. In a second variant, an illustrative image of the slaughtered poultry body is captured by a color camera and the computer-based production of the color image in the computer, which simply selects the predetermined region by means of software apertures and respectively accumulates only the individual color components, by means of which the mixed color light is consequently produced simply by means of software. It is advantageous to use a narrow band barrier filter to suppress a monochromatic background.
In principle, it is conceivable to~link suitable threshold switches to each piece of color data via logical subassemblies in order to achieve the evaluation. The computer preferably used for evaluation and selection control includes only the evaluation routines and in the second variant, also includes the routines for the accumulation within the boundaries of the predetermined region as well as optionally for control purposes, also includes an intermediate memory region for a color image region. In the second variant, the accumulation of the respective color components is executed within the -preferably rectangular - boundaries of the color image region directly during the feeding of this image from the color camera. In principle, therefore, a micro-controller is sufficient as the computer. In particular, photographic image processing routines and their continuous performance parameters are not required.

In principle, therefore, a micro-controller is sufficient as the computer. In particular, photographic image processing routines and their continuous performance parameters are not required.
3 Preferably, the color signals (red, green, blue) used by conventional color light sensors or color cameras which are close to the spectral sensitivities of the human eye are used for the color analysis of the mixed color light.
However, it is also conceivable to use other spectral regions. The individual color signals of the mixed color light determine the color in the chromatic circle by means of their relative components and determine the color saturation and luminosity by means of their absolute intensity. With the color signals or alternatively with the color, color saturation, and luminosity, every detectable state of the mixed light can simply be described analytically, preferably vectorially in a mufti-dimensional space. In particular, definite spatial regions can be defined which correspond to the selection criteria. Such selection criteria are, for example, missing body parts, burns, reddenings, missing skin, protruding bones, etc.
The totality of all the spatial regions should preferably fill the entire space without overlaps. If parameters of the analyzed mixed color light lie within a spatial region of these selection criteria, then the associated selection or identification, screening, partial processing is activated.
It is also conceivable that for each measurement and color, a color balancing is executed by means of the integral average of a multitude of slaughtered poultry bodies detected - white balancing - and preferably in alternation, by means of the integral average of only the background - black balancing -, by virtue of the fact that this integral average is respectively treated before the evaluation as the norming quantity - which is used as a

4 divisor - or as an offset - which is subtracted from the measurement value ahead of time. As a result, fluctuations in the light conditions or characteristic values do not have a significant effect on the evaluation result. The norming produces a projection of the evaluation space onto an associated evaluation plane, preferably color and color saturation.
There is also the possibility, through the use of a specially adapted aperture, of using a number of color light sensors which are each associated with a particular body part or body section of the slaughtered animal (breast, left leg, right wing). With the use of a color camera, the selection of the different body parts and body sections to be controlled can take place by means of a number of software apertures.
In a favorable manner, the control device could if necessary also include two similar arrangements of color light sensors which are disposed opposite from each other and thus simultaneously control the backscattered mixed color light from the front and back of the slaughtered poultry body.
Another possible embodiment of the control device could include the additional rear disposition of an optical mirror opposite from the color light sensor so that at the same time, the backscattered mixed color light can be received and controlled from two opposing sides of the slaughtered poultry body.
The invention will be explained in more detail as an exemplary embodiment in Fig. 1 as variant 1 with optical apertures and in Fig. 2 as variant 2 with software apertures.
According to Fig. l, the device for automatically controlling and selecting slaughtered poultry bodies with optical apertures is comprised of an illumination device 1 that emits white light, an aperture 2 in front of the slaughtered poultry body, which narrowly encompasses the visible outline, an objectiveless color light sensor 3, which in a position-triggered manner, receives the diffuse mixed color light backscattered by the slaughtered poultry body and whose color data are transmitted to a computer 5 via a line 4. The computer 5 executes a color analysis 6 of the backscattered mixed color light based on the color signals used. After internal evaluation 7 of the color analysis according to selection criteria 8, a control signal 9 is emitted in accordance with the respective selection type associated with the slaughtered poultry body in order to trigger selection devices in the technological process.
According to Fig. 2, a possible variant of the device for automatically controlling and selecting slaughtered poultry bodies with software apertures 10 is comprised of an illumination device 1 that emits white light, a color camera 11 with a color sensor array whose color image is transmitted to a computer 5 via a line 4. A predetermined region of the color image is selected by means of a software aperture 10 when being fed into the computer 5 and the respective color data are accumulated in a color data memory 12. This can advantageously occur in line-by-line transmission of the color image if, by means of suitable counters, a rectangular region is selectively filtered with regard to lines/columns as a software aperture 10. The computer S executes a color analysis 6 of the represented mixed color light based on the color data memories 12. After internal evaluation 7 of the color analysis 6 according to the selection criteria 8, a control signal 9 is emitted in accordance with the selection type associated with the respective slaughtered poultry body in order to trigger selection devices in the technological process.
