[0023] The purpose of this invention is to provide an automated image acquisition device for standard phenotypic images of wolfberries, which solves the problems existing in the prior art. It has a simple structure, is easy to use, and effectively improves work efficiency and image acquisition accuracy.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides an automated image acquisition device for standard phenotypic images of wolfberry, such as... Figures 1-2As shown, the system includes: a platform 1, an image acquisition unit 3, and a light source 2. The platform 1 is used to place goji berries; the image acquisition unit 3 is used to photograph the goji berries and convert optical signals into electrical signals for transmission to a computer; the light source 2 provides illumination to the platform 1 and ensures uniform lighting to eliminate shadows during image acquisition. Setting up the platform 1 facilitates standardized operation; placing goji berries in specific positions for each photograph helps improve the consistency of image acquisition, providing a reliable foundation for subsequent image analysis and data processing. The image acquisition unit 3 can accurately photograph the goji berries, capturing their detailed features and providing raw data for the accurate extraction of goji berry phenotypic characteristics. The system collects data and converts the optical signals generated during shooting into electrical signals and transmits them to computer equipment, realizing the digital acquisition and processing of images. This allows images to be efficiently stored, analyzed, and applied. Light source 2 provides illumination to ensure uniform light, eliminating shadows during image acquisition. This makes the captured images of goji berries clearer and brighter, reducing image quality problems caused by uneven lighting. Uniform lighting helps to highlight the characteristics of goji berries, enhances the contrast between goji berries and the background, and facilitates better identification and shooting of goji berries by image acquisition device 3. This improves image quality and recognizability. Eliminating shooting shadows can avoid misjudgment of phenotypic features caused by shadow interference, improving the accuracy and reliability of phenotypic feature extraction.

[0026] In a preferred embodiment, the light source 2 includes a light source box 21 and multiple lighting lamps 22. The bottom of the light source box 21 is used to place the loading platform 1. A material inlet / outlet 24 is provided on one side wall of the light source box 21. The multiple lighting lamps 22 are located on the top of the light source box 21. A collection hole 23 is provided on the top of the light source box 21. The collection hole 23 is used for image acquisition by the image acquisition device 3. The light source box 21 provides a relatively enclosed space for the lighting system, reducing external light interference and ensuring the stability of the lighting. The multiple lighting lamps 22 located on the top can evenly illuminate the goji berries on the loading platform 1 from above, effectively eliminating shadows. The material inlet / outlet 24 facilitates the insertion and removal of goji berries, improving operational convenience. The collection hole 23 enables the image acquisition device 3 to accurately acquire images, ensuring the fixation and accuracy of the acquisition position.

[0027] In a preferred embodiment, the light source used in the illumination lamp 22 mainly includes halogen lamps, fluorescent lamps, LED lamps, xenon lamps, etc., with white LED lamps being preferred. White LED lamps generate less heat, consume less energy, and have a long service life. They can effectively eliminate color shift, provide uniform and stable illumination for image acquisition, ensure the accuracy of image colors, and improve image quality.

[0028] In a preferred embodiment, the loading platform 1 is a white background plate. The white background plate can eliminate color difference problems, so that the goji berries are clearly distinguished from the background when shooting, highlighting the characteristics of the goji berries, making it easier for the image acquisition device 3 to better identify and shoot, and improving the clarity and recognizability of the image.

[0029] In a preferred embodiment, the image acquisition device 3 includes a digital camera 31 and a data cable. The digital camera 31 is equipped with a digital sensor, which captures optical signals of an image and converts them into electrical signals. One end of the data cable is electrically connected to the digital camera 31, and the other end is electrically connected to a computer device to transmit the electrical signals. The digital camera 31 can accurately capture images of goji berries. The digital sensor converts optical signals into electrical signals, enabling the images to be digitally processed and stored. The data cable transmits the electrical signals to the computer device, facilitating subsequent image analysis and processing, thus achieving automation and efficiency in image acquisition. Preferably, the digital camera 31 is a Daheng CMOS camera, model MER-302-56U3C.

[0030] In a preferred embodiment, the sensor is a CMOS sensor, which is low in cost, low in power consumption, and fast in access speed. With technological advancements, its quality continues to improve; its low noise and high resolution characteristics are suitable for wolfberry image acquisition, reducing equipment costs while meeting image quality requirements.

[0031] In a preferred embodiment, the digital camera 31 uses a fixed-focus lens. Fixed-focus lenses offer higher image quality, closer focusing and working distances at the same price point, and less distortion. This provides high-quality imaging for wolfberry image acquisition, accurately capturing the detailed features of wolfberries and improving image clarity and accuracy.

[0032] In a preferred embodiment, the image acquisition device 3 further includes a bracket 32 ​​and a telescopic component. The bracket 32 ​​is disposed outside the light source box 21. The fixed end of the telescopic component is fixedly connected to the bracket 32, and the movable end of the telescopic component is fixedly connected to the digital camera 31, enabling the digital camera 31 to move in the axial direction of the acquisition hole 23 and maintain its position after movement. The bracket 32 ​​provides stable support for the telescopic component and the camera, ensuring the stability of the camera during movement. The telescopic component allows for flexible adjustment of the camera's position. When the acquired image effect is not ideal, the distance between the camera and the platform 1 can be adjusted to obtain an ideal image, improving the adaptability and flexibility of image acquisition.

[0033] In a preferred embodiment, the telescopic component is a lead screw module 33.

[0034] In a preferred embodiment, the lead screw module 33 includes a ball screw, a linear guide, an aluminum alloy profile, a lead screw support, a coupling, a motor, an electromagnetic switch, etc.

[0035] In a preferred embodiment, both ends of the ball screw are fixedly mounted on an aluminum alloy profile via screw support seats. The screw support seats support and stabilize the ball screw, ensuring it does not wobble or shift during operation. One end of the ball screw is connected to a motor via a coupling. The coupling transmits the motor's rotational power to the ball screw, enabling it to rotate. A linear guide is mounted on the aluminum alloy profile, parallel to the ball screw. The linear guide provides guidance for the linear motion of the moving parts, ensuring smoothness and accuracy. The aluminum alloy profile serves as the frame structure of the entire screw module 33, providing a mounting base for other components. It connects the ball screw, linear guide, screw support seats, and other components together to form a unified whole. The motor is connected to the ball screw via a coupling, providing power for its rotational motion. The motor is typically mounted on the aluminum alloy profile using bolts or other fixing methods to ensure its stability. An electromagnetic switch is typically mounted on the aluminum alloy profile and connected to the motor's control system. The electromagnetic switch controls the start, stop, and forward / reverse rotation of the motor, achieving precise control of the movement of the lead screw module 33. Through the connection of these components, the lead screw module 33 converts the rotary motion of the motor into linear motion. During operation, the motor drives the ball screw to rotate via the coupling, and the nut on the ball screw moves linearly along the axis of the ball screw. Simultaneously, the linear guide rail provides guidance for the linear motion of the nut, ensuring smoothness and accuracy. The electromagnetic switch controls the start, stop, and forward / reverse rotation of the motor, achieving precise control of the movement of the lead screw module 33.

[0036] In a preferred embodiment, the lead screw module 33 is provided with a first shooting station, a second shooting station, and a third shooting station. The distance between the digital camera 31 at the first shooting station and the platform 1 is 30cm, the distance between the digital camera 31 at the second shooting station and the platform 1 is 35cm, and the distance between the digital camera 31 at the third shooting station and the platform 1 is 40cm. This provides three different shooting distance options, allowing the camera position to be adjusted according to actual conditions to meet the requirements of different sized goji berries or different shooting needs, thus improving the versatility and practicality of the device. At the same time, the fixed shooting stations facilitate operation and standardize the data acquisition process.

[0037] The following is the usage process of the automated image acquisition device for standard wolfberry phenotypic images:

[0038] Step 1: Preparation Phase

[0039] Place the device in a suitable working position to ensure that the ambient light does not interfere too much with the lighting system.

[0040] Check that all components are properly connected, especially the connection between the digital camera 31 in the image acquisition unit 3 and the data cable and telescopic component, as well as the fixed connection between the telescopic component and the bracket 32.

[0041] Confirm that the lighting lamp 22 in light source 2 is working properly, and the white LED lamp should be able to provide uniform and stable lighting.

[0042] Inspect platform 1 to ensure the white background is clean and free of debris so that the goji berry features can be better highlighted.

[0043] Step 2: Place the goji berries

[0044] By placing the goji berries to be imaged onto the loading platform 1 (white background) through the material inlet / outlet 24 on one side wall of the light source box 21, the position of the goji berries is adjusted to place them in the best shooting area.

[0045] Step 3: Adjust the image acquisition device 3

[0046] Choose a suitable shooting location based on the size of the goji berries and your shooting requirements. If unsure, you can try pre-shooting at different locations to observe the image effects.

[0047] If you are not satisfied with the default shooting position, you can adjust the distance between the digital camera 31 and the platform 1 by operating the telescopic component (screw module 33). For example, when a closer shooting distance is needed to capture the details of the goji berries, the camera can be adjusted to a closer position; when the goji berries are large and a farther shooting distance is needed to obtain a complete image, the camera can be adjusted to a farther position.

[0048] A fixed-focus lens can provide high-quality imaging after the distance is adjusted, ensuring that the detailed features of goji berries are captured clearly.

[0049] Step 4: Begin image acquisition

[0050] Once the camera position is adjusted, turn on the lighting 22 in the light source 2. The white LED light shines evenly on the goji berries on the platform 1 from the top of the light source box 21, eliminating shadows and providing good lighting conditions for image acquisition.

[0051] The CMOS sensor inside the digital camera 31 captures the optical signals of the goji berry image and converts them into electrical signals.

[0052] Electrical signals are transmitted to computer equipment via a data cable, and the computer equipment digitizes and stores the images.

[0053] Step 1: Image Analysis and Processing

[0054] On computer equipment, relevant image analysis software can be used to analyze and process the acquired goji berry images. For example, phenotypic characteristics such as the size, shape, and color of the goji berries can be measured, and image enhancement and noise reduction operations can be performed to improve image quality.

[0055] Based on the analysis results, the parameters of the device can be adjusted, such as readjusting the camera position and lighting intensity, to obtain more satisfactory images.

[0056] Step 6: End the data collection

[0057] After image acquisition and analysis are completed, turn off light source 2 and image acquisition device 3.

[0058] Goji berries are retrieved from the cargo platform 1 via material inlet / outlet 24.

[0059] Clean and maintain the device to ensure it functions properly the next time it is used.

[0060] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
