Research on Potato Appearance Quality Detection Based on Computer Vision

Aiming at the appearance quality detection of potato, this paper proposes an image feature detection and recognition algorithm based on computer vision. Firstly, the image of the potato obtained by the computer vision system was analyzed, and the background image of the potato was removed by Otsu method. Then the image processing and recognition were carried out for the green skin, germination and mechanical damage state of the potato. For the green skin state of potato, the normal and green skin areas of potato are discriminated by the similarity of pixel Euclidean distance. For the potato sprouting from the epidermis, the germination area of the potato is detected by the gray difference method of the image G channel. Finally, the edge information and image geometric features are used to determine the damage site of the potato epidermis, and finally the appearance quality of the potato is detected.
