Fuente: WIPO "processing tomato" The invention relates to the technical field of image processing, in particular to a tomato extract purity detection method and system based on artificial intelligence, and the method comprises the steps: obtaining a to-be-crushed tomato image after cleaning is completed, and converting the tomato image into a grayscale image; extracting a tomato region in the grayscale image, and obtaining the maturity of the tomato according to the color feature of the tomato region; the tomato extract is obtained, and the tomato extract is a substance extracted after tomatoes are processed. According to the method, the concentration of the tomato extract can be accurately detected and evaluated by adopting an artificial intelligence method, and whether the filtering operation of the filtering membrane is stopped or not can be determined according to the detected concentration grade of the tomato extract until the tomato extract meeting the concentration requirement is obtained, and then the filtering operation of the filtering membrane is stopped, so that the filtering operation of the filtering membrane is stopped. And the accuracy of a tomato extract concentration detection result is improved.
