The material of the chassis 1 is metal, and the inner wall of the chassis is black except for the white bottom surface, so as to reduce the possibility of reflection when shooting images. A metal frame is provided at the internal connection of the chassis 1. The metal frame serves as a structural support to provide stable support for the internal electronic components and optical components to prevent damage caused by vibration or external force. As an effective electromagnetic shielding layer, it can reduce the influence of electronic noise and other interference signals, thereby improving the image quality. In addition, metal is a good thermal conductor. When the heating element inside the device generates heat, the heat can be conducted to the metal frame through the surface in contact with the metal frame, and the metal frame plays a role in heat dissipation through its high thermal conductivity and good heat dissipation performance.
[0031] Reference Figure 2 and Figure 3 A first camera 4 is mounted on the top inner wall of the chassis 1 through a first mounting bracket 7, a second camera 5 is mounted on the side wall of the chassis 1 through a second mounting bracket 8, an egg placement rack 6 is arranged on the bottom surface of the chassis 1, the egg placement rack 6 is vertically arranged on the bottom surface of the chassis 1, and an egg placement portion 9 is arranged on the top thereof, the egg placement portion 9 can be a white tray or a concave suction cup, which is used to place the eggs upright on the egg placement rack 6; the white color of the bottom surface of the chassis and the white tray at the bottom of the eggs can provide a good background contrast, which helps to highlight the dark spots on the eggshell, and it should be ensured that the white area is uniform and has no mottled colors or shadows. The lenses of the first camera 4 and the second camera 5 are both facing the egg placement rack 6 and corresponding to the eggs placed thereon, and are used to shoot the eggshell from multiple directions and angles to obtain a three-dimensional eggshell image.
[0032] The bottom surface of the inner part of the chassis 1 is also provided with a surface light source 10, which is used to place and illuminate the crops to be tested when testing, that is, when used as a test, the crops such as rice ears are placed on the surface light source 10, the surface light source 10 is turned on to illuminate the crops such as rice ears, and the camera is started to shoot; the device of the present application is also provided with a point light source, which is arranged in the egg placement rack 6 at a position directly below the egg placement part, and the point light source is a lamp, which is used to illuminate the egg shell when testing the egg shell. The surface light source and the point light source can be controlled independently and can be turned on or off independently as needed.
[0033] The first camera 4 and the second camera 5 of this embodiment 1 are both equipped with high-resolution CMOS or CCD image sensors, which can capture tiny details on the egg shell; the detection equipment of this embodiment also includes a control system, which includes a lens driving circuit, an automatic exposure control system, an automatic white balance system, a digital signal processor (DSP), an automatic focus module, an image stabilization module and a computer or display, wherein the lens driving circuit is used to control the focal length and aperture size of the lens to ensure that the egg is within the focus range and that there is enough light entering the camera; the automatic exposure control system can automatically adjust the exposure time according to the ambient light conditions to obtain appropriate image brightness; the automatic white balance system can correct color shift under different light sources to ensure accurate color reproduction; the digital signal processor (DSP) is used to process image data and perform operations such as noise suppression, contrast enhancement, and sharpening; the automatic focus module can use phase detection, contrast detection or other technologies to achieve fast and accurate automatic focus; the image stabilization module has integrated optical image stabilization (OIS) or electronic image stabilization (EIS) The camera also includes an IS function to reduce blur caused by device shaking; the ability to communicate with external devices (such as computers or monitors) to transmit image data and receive control instructions; and power management circuits to provide a stable power supply for the entire camera system and optimize power consumption.
[0034] In order to clearly capture the dark spots on the egg, the imaging principle followed is: Reflection and transmission of light: When light hits the eggshell, part of the light is reflected and part of it is absorbed. The dark spot area may react differently to light due to differences in eggshell thickness or structure; Lens focusing: The optical image of the object (egg) is projected onto the image sensor through the lens. The lens should have sufficient resolution and contrast to capture the details on the eggshell; the image sensor captures the light signal: the image sensor (such as CMOS or CCD) converts the received light signal into an electrical signal; analog-to-digital conversion (ADC): the electrical signal is then converted into a digital signal for subsequent digital image processing; image processing: the digital signal processor (DSP) applies algorithms to process the image, including noise suppression, contrast enhancement, sharpening, etc., to improve the visibility of dark spots; color restoration: accurately correct the white balance to ensure color accuracy; autofocus: fast and accurate autofocus is achieved through phase detection, contrast detection or other technologies, so that the dark spots on the egg surface always remain clear; exposure control adjusts the exposure time according to the ambient light conditions to avoid loss of details due to overexposure or underexposure; anti-reflection measures: use polarizers or other anti-reflection measures to reduce the reflective effect on the eggshell surface.
[0035] The method of using the intelligent detection device of the present application to detect dark spots on egg shells is as follows:
[0036] 1. Egg positioning: First, the eggs in the tray need to be placed in a specific position at the bottom of the chassis. The white tray at the bottom can provide good background contrast to help highlight the dark spots on the eggshell. Make sure the white area is uniform and has no color or shadows, and the surrounding area is designed to be black to reduce the possibility of reflection.
[0037] 2. Close the door and turn on the light from the point source: When the door is closed, the eggs are in a dark environment, which helps reduce the impact of ambient light and enables the camera to capture a clearer image of the eggs.
[0038] 3. The light at the bottom of the case turns on, illuminating the eggshell. Different eggshell colors will reflect light at different intensities, and these differences will be captured by the camera.
[0039] 4. Image Capture: The top and bottom right cameras take pictures of the egg from different angles. These pictures have enough resolution to clearly show any dark spots on the eggshell.
[0040] 5. Image processing: The captured image is sent to a computer for processing. At this stage, digital image processing techniques are used to enhance contrast, remove noise, and highlight dark areas.
[0041] 6. Dark spot identification and quantification: By analyzing the processed image, the system can identify the dark spots on the eggshell. This usually involves methods such as threshold segmentation and edge detection. For example, a gray value threshold can be set, and pixels above this threshold are considered to be dark spot areas.
[0042] 7. Data calculation and reporting: After the dark spots are identified, the extent of the dark spots can be quantified by calculating parameters such as the area of the dark spots:
[0043] Calculate the area: For each dark spot, you can treat it as a polygon and use the following formula
[0044] The dark spot ratio is obtained by dividing the dark spot area by the red area, and a score or classification of the egg is obtained by this.
[0045] 8. Result output: Finally, the system can output information about the degree of dark spots based on the quantitative results, such as giving a score or classification (such as mild, moderate, or severe dark spots), to help users judge the quality of the eggs.
[0046] When the device of the present application is used for seed testing, the steps are similar to those described above, with the difference that the crops are placed on the surface light source 10, and only the surface light source 10 needs to be turned on without turning on the point light source; at this time, the image processing system can analyze the captured crop images, and the analysis includes but is not limited to checking the empty shell situation, segmenting and counting.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
