Abstract
A sexing apparatus 100 includes irradiation means for irradiating each of hen eggs within a predetermined period of time from start of incubation with light having a predetermined wavelength, imaging means for imaging each of the irradiated hen eggs, means for generating a sexing model using, as training data, a result of separately sexing the hen eggs and image data obtained by the imaging of the hen eggs, and means for sexing a new target hen egg by inputting an image data obtained for the target hen egg by the irradiation means and the imaging means into the sexing model.
Claims16
A sexing apparatus comprising:
- an irradiation means for irradiating one or more hen eggs within a predetermined period of time from a start of an incubation with light having a predetermined wavelength, wherein the irradiation means comprises a first light source and a second light source, and wherein the light comprises a wavelength in a visible light from the first light source and a wavelength in a near-infrared light range from the second light source;
- an imaging means for imaging the one or more hen eggs during irradiation to generate image data;
- a means for generating a sexing model using, as training data, a result of separately sexing the one or more hen eggs and the image data, wherein the sexing model comprises threshold parameters, wherein each of the threshold parameters is configurable, and wherein the threshold parameters comprise a collection method, a day, a female determination threshold, and a weight;
- and
- a means for sexing a target hen egg by:
- respectively setting a first value and a second value for the day and the female determination threshold of the threshold parameters, wherein the sexing model utilizes the day of the threshold parameters to perform the sexing of the target hen egg at or less than three days as the predetermined time from the start of the incubation;
- receiving target hen image data from a subsequent irradiation by the irradiation means and a subsequent imaging by the imaging means of the target hen egg, and
- inputting into the sexing model the target hen egg image data to generate a sex of the target hen egg.
A sexing method comprising:
- irradiating, by a first light source and a second light source, one or more hen eggs within a predetermined period of time from a start of an incubation with light having a predetermined wavelength, the light comprising a wavelength in a visible light from the first light source and a wavelength in a near-infrared light range from the second light source;
- imaging the one or more hen eggs during irradiation to generate image data;
- generating a sexing model using, as training data, a result of separately sexing the one or more hen eggs and the image data, wherein the sexing model comprises threshold parameters, wherein each of the threshold parameters is configurable, and wherein the threshold parameters comprise a collection method, a day, a female determination threshold, and a weight;
- and
- sexing a target hen egg by:
- respectively setting a first value and a second value for the day and the female determination threshold of the threshold parameters, wherein the sexing model utilizes the day of the threshold parameters to perform the sexing of the target hen egg at or less than three days as the predetermined time from the start of the incubation;
- receiving target hen image data from a subsequent irradiation and a subsequent imaging of the target hen egg, and
- inputting into the sexing model the target hen egg image data to generate a sex of the target hen egg.
