Image recognition method based on mask contour tracking and related products

The invention discloses an image recognition method based on mask contour tracking and a related product, and the method comprises the steps: carrying out the binarization processing of an obtained image, and obtaining a binary image of which the pixel value is a first value or a second value; scanning the binary image pixel by pixel according to a preset rule, and taking a pixel point of which the first pixel value is a second value as a first target contour point; taking the first target contour point as the center of a mask area, and taking a pixel point of which the first pixel value is a second value as a second target contour point in the mask area according to a preset rule; taking the second target contour point as the center of a mask area, and taking a pixel point of which the first pixel value is a second value as a third target contour point in the mask area according to a preset rule; and if the third target contour point is the end point of the target contour, identifying a target image enclosed
