Fruit body outer contour deformity detection method

The invention discloses a fruit body outer contour deformity detection method which comprises the following steps: S1, collecting a color image of a fruit outer contour, and converting the color imageinto a grayscale image; S2, performing image segmentation processing on the grayscale image, and extracting a boundary region of a fruit body in the image by adopting a canny algorithm; S3, pixel point coordinates of the fruit body boundary are obtained clockwise by adopting a pixel tracking method for the fruit body boundary; S4, judging the concavity and convexity of the outer contour of the fruit body by adopting a right-hand rule; and S5, comparing the number of concave property points of the outer contour of the fruit body with a preset threshold value to judge whether the fruit body isrejected or reserved. According to the method, the degree of concave-convex defects on the surface of the fruit body is detected by using software based on a computer, so that the abnormal fruit bodyis removed at a certain pre
