Provided in the present invention are a multi-channel tongue body edge detection device and method, and a storage medium. The method comprises the steps of: obtaining, by using a red area enhancement algorithm, an R-channel gray enhancement image of an RGB image of a tongue body, converting the RGB image into an HSI image and an HSV image respectively, extracting an H-channel gray image from the HSI image, and extracting a V-channel gray image from the HSV image; traversing potential contour points based on a cost function to obtain the optimal initial contour points, and filling all the optimal initial contour points to obtain an initial contour binary image; removing a white area of a V-channel binary image in the initial contour binary image to obtain a final contour binary image; and obtaining final edge point information based on the final contour binary image, and processing the final edge point information by a GVF-snake segmentation algorithm to obtain a final tongue body segmentation image. By means of the present invention, the initial contour of a tongue image can be effectively extracted, thereby improving the accuracy of tongue image segmentation.
