Description

Technical Field

[0001] The utility model relates to an image collection device for egg quality inspection, belonging to the technical field of poultry egg quality inspection equipment. Background Art

[0002] Eggs are the most economical animal protein widely accepted by the general public. The main factor that determines whether consumers buy eggs is the appearance quality of the eggs, and the dark spots on the eggshell surface are one of the important indicators to measure the appearance quality of eggs.

[0003] At present, the main method for detecting dark spots on eggs is manual evaluation, which judges the freshness and quality of eggs by manually observing the dark spots on the surface of eggs. However, manual evaluation is subjective and easily affected by individual subjective factors. It also requires a lot of manpower and time investment, which is inefficient and not conducive to large-scale production and testing. Manual evaluation methods are affected by factors such as ambient light and are prone to misjudgment. Manual evaluation requires the employment of a large number of testers, which increases production costs and is not conducive to reducing product prices.

[0004] With the popularization of artificial intelligence and automated production, the current egg quality inspection system uses advanced surface image recognition engines, which not only makes the egg quality inspection process more intelligent and reliable, but also improves production efficiency and product quality. This method not only requires egg images as training sets to optimize model performance, but also requires a large number of egg images as reference sets to provide support for real-time recognition. However, the existing egg quality inspection platform is limited and expensive, which is not convenient for large-scale promotion and difficult to benefit ordinary egg producers. In view of this, we propose an image collection device for egg quality inspection. Utility Model Content

DETAILED DESCRIPTION

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0051] Figure 1 The overall structure of an image collection device for egg quality inspection provided by the utility model is shown, including a shooting mechanism 1 and an illumination mechanism 2, wherein the shooting mechanism 1 and the illumination mechanism 2 are adapted to each other, that is, the two are connected to each other to form a whole. The length, width and height ratios of the shooting mechanism 1 and the illumination mechanism 2 can be determined according to the focal length of different shooting devices (for example, mobile phones, cameras), and the size of the box can be minimized as much as possible under the premise of a suitable focal length, so as to facilitate carrying or moving.

[0052] Figure 2 The structure of the photographing mechanism 1 is shown, including: a box door 11 and a box top 12. There are two box doors 11, which are symmetrically arranged on the two side walls of the photographing mechanism 1, and two handles 111 are symmetrically arranged on the two box doors 11. The box door 11 is connected to the photographing mechanism 1 by sliding or flipping. Preferably, the box door 11 is a side wall of the photographing mechanism 1.

[0053] The top of the box 12 includes: a square groove 121, a protective member 122. Optionally, the top of the box 12 further includes a light strip 124, a light strip switch 125 ( Figure 3 ).

[0054] A square groove 121 is provided at the center of the diagonal of the top 12 of the box for placing the photographing device, and the center of the square groove 121 is on the same vertical line as the center of the circular hole 231. The size of the square groove 121 may vary depending on the photographing device. For example, when the photographing device is a mobile phone, the side length of the square groove 121 may be 5-10 cm.

[0055] A plurality of protective components 122 are arranged on the inner wall of the box top 12, and a circular hole 123 is opened in the center of the protective component 122. When the shooting device is placed directly above the square groove 121, a rope or other linear material extends from the circular hole 123 to fix the shooting device to prevent it from moving during the shooting process, thereby better improving the stability of the device and maintaining the image collection quality. Preferably, the protective component 122 is in the shape of an arch, and 4-8 of them are symmetrically arranged around the square groove 121.

[0056] Optionally, a light strip 124 and a light strip switch 125 are provided on the inner wall of the box top 12 for auxiliary lighting; Optionally, the light strip switch 125 is a round button; Preferably, the light strip switch 125 is provided on the left side of the light strip 124 ( Figure 4 ).

[0058] A circular hole 231 is provided at the center of the diagonal line of the top wall 23 of the box body. The diameter of the circular hole 231 should be smaller than the maximum diameter of an ordinary egg when placed vertically, so as to ensure that the egg can be placed stably on the hole and will not fall. For example, the diameter of the circular hole 231 is 1 cm.

[0059] An LED spotlight 211 and a two-position screw terminal 218 are provided on the bottom wall 21 of the box. The LED spotlight 211 is vertically arranged at the center of the diagonal of the bottom wall 21 of the box. The LED spotlight 211 includes: a point light source 212 and a condenser 213 ( Figure 6 ).

[0060] The point light source 212 is an LED point light source, the color temperature of the LED point light source is 2800K, the luminous flux is at least 1000lm, the color temperature of the light source cooperates with the image acquisition parameters to reduce the difference in light absorption caused by different eggshell colors, and the luminous flux ensures that all eggshell dark spot image features are fully displayed. The point light source is a relatively concentrated light-emitting point, and the point light source is selected to avoid the interference of light diffuse reflection on the image sample features.

[0061] A number of circular light-transmitting holes 214 with a diameter of about 0.5 cm are evenly spaced at the top of the point light source 212. Preferably, a central light-transmitting hole 214 with a diameter of 0.5 cm is set at the top of the point light source 212 with the vertical line where the circular hole 231 is located as the center and 5 cm away from the circular hole 231, and 35 identical light-transmitting holes 214 are evenly spaced in a concentric circle manner. The top of the point light source 212, that is, the distance between the position where the light-transmitting hole 214 is located and the top wall 23 of the box body is 3-10 cm, preferably 5 cm, and the top of the point light source 212 is a black light-absorbing material. The setting of the light-transmitting holes should ensure that the light of the LED point light source is taken into the lighting device as parallel light, eliminate the intensity attenuation of the LED point light source caused by different optical paths, and reduce the occurrence of light scattering.

[0062] On the outside of the point light source 212, a condenser 213 is tightly surrounded. The condenser 213 is perpendicular to the plane where the light-transmitting hole is located, and the two ends are respectively fixedly connected to the bottom wall 21 of the box and the top wall 23 of the box, together surrounding the point light source 212 to ensure that the parallel light path remains unchanged. Four square openings 216 are equidistantly provided at the bottom of the condenser 213 to facilitate access to the power cord. Optionally, a plurality of connecting members 217 are provided on the outside of the condenser 213 to fix the condenser. For example, four connecting members 217 are symmetrically arranged, and the condenser 213 is connected to the front and rear side walls of the box through the connecting members 217 ( Figure 7 ).

[0063] There is also a base 215 extending vertically downward at the bottom of the point light source 212 to ensure the stability of the device and the sealing of the overall structure, so as to ensure that the angle of the eggs is unchanged and the dark box is absolutely dark. Preferably, the point light source 212 is fixedly connected to the bottom wall 21 of the box body through the base 215 with a height of 1 cm and a cylindrical shape.

[0064] The two-position screw terminal 218 arranged on the bottom wall 21 of the box body is opposite to the square opening 216 and is horizontally arranged between the square opening 216 and the front side wall 22 of the box body. The front side wall 22 of the box body refers to the side of the four side walls of the box body that faces the operator during operation or the side wall where the power switch is located.

[0065] A light source switch 221, a heat dissipation port 222 and a power line opening 223 are provided on the front side wall 22 of the box body. The power line opening 223 is directly opposite to the two-position screw terminal 218, and the light source switch 221 and the heat dissipation port 222 are distributed on both sides of the power line opening 223.

[0066] Optionally, a support member 232 is further provided on the top wall 23 of the box body to maintain the stability of the device. Preferably, the support member 232 is in the shape of a cuboid, eight of which are arranged equidistantly at the four corners and the center points of the four corners of the box body, and fixed to the bottom wall 21 of the box body to form a horizontal brace.

[0067] Preferably, the lighting mechanism 2 and the shooting mechanism 1 are made of light-shielding material, supporting only a single point light source 212, preventing interference from other light, and protecting the egg image to the greatest extent. Specifically, at least the box door 11, the box top 12, the box bottom wall 21, the box top wall 23, the condenser 213, and the light-transmitting hole 214 are made of light-shielding material or black light-absorbing material, and the interior of the image collection device is a dark box environment.

[0068] The operation process of collecting egg images by the egg image collection device provided by the utility model is as follows:

[0069] 1. Preparation

[0070] The first step is to turn on the light source switch 221 to ensure that the point light source 212 is above 1000 lumens;
