[0002] Chili peppers, a widely cultivated and consumed economic crop globally, rely heavily on fruit color for ripeness assessment, significantly influencing product grading, pricing, and market demand. Traditional chili pepper color detection primarily relies on manual visual inspection, which suffers from low efficiency, high subjectivity, and labor intensity, failing to meet the demands of modern large-scale, standardized agricultural production. With the rapid development of computer vision technology, automated detection methods based on image processing have become a research hotspot in agriculture. However, existing chili pepper color detection equipment generally suffers from poor adaptability, insufficient accuracy, and inconvenient adjustment, making it difficult to address the detection needs of different varieties and growth stages. Especially in actual production environments, factors such as the placement of chili peppers, lighting conditions, and background interference significantly impact detection results. Furthermore, the fixed camera positions in existing equipment limit the detection range, impacting efficiency and accuracy due to the difficulty in adjusting to chili pepper size and conveyor belt speed. Therefore, there is an urgent need to develop an intelligent recognition device capable of automated chili pepper color detection with high adaptability and adjustability to improve detection efficiency, reduce labor costs, and provide technical support for the intelligent development of the chili pepper industry.

[0039] It should be noted that the operation process of this chili pepper color detection and recognition device is as follows: The controller starts the conveyor belt 101, and the chili peppers to be detected are evenly placed on the conveyor belt 101. The infrared sensor monitors the position of the chili peppers in real time and feeds back to the controller. When the chili peppers enter the camera area, the controller starts the servo motor, drives the threaded screw 106 to rotate, and drives the threaded slider 107 to move horizontally along the slide groove 103, thereby adjusting the horizontal position of the camera 201 to ensure that the camera 201 can be aligned with the chili peppers. In addition, according to the actual detection needs, the height of the camera 201 can be adjusted by adjusting the relative position of the first adjusting block 203 and the second adjusting hole 205 on the inverted U-shaped support frame 102 and fixing it with the pin 206 to adapt to the detection needs of chili peppers of different sizes. The camera 201 collects image data of the chili peppers and displays the detection results in real time through the LED display 207. The image processor processes the image data, analyzes the color of the chili peppers, and completes the grading and recognition.
[0040] In summary, the horizontal position adjustment of the camera 201 is achieved by driving the threaded screw 106 with a servo motor. Combined with the height-adjustable inverted U-shaped support frame 102, it can flexibly adapt to the detection needs of pepper fruits of different sizes and improve detection accuracy. The infrared sensor and controller work together to achieve automated detection and improve detection efficiency. The LED display 207 provides real-time feedback of detection results, which is convenient for operators to monitor and adjust. The overall structure is reasonably designed, easy to operate, and reduces labor costs. It is suitable for pepper fruit color detection in large-scale production and provides reliable technical support for the intelligent development of the pepper industry.
