Large-area animal fur contour image cutting method based on radius increment constraint

Abstract

The invention discloses a large-area animal fur contour image cutting method based on radius increment constraint, and the method comprises the steps: horizontally placing animal fur on a rubber plate for preprocessing, and obtaining a contour image of the image; establishing a corresponding coordinate system to obtain a centroid coordinate, setting the centroid coordinate as a new coordinate system origin, and establishing a new coordinate system; taking the origin of coordinates as the center, drawing a ray clockwise along the positive direction of the X axis, dividing the contour into n equal parts with the same angle, marking the intersection point of the ray and the edge contour point as an initial point, and defining the Euclidean distance between the initial point and the center of mass as the radius length of the contour; defining the ratio of the contour radius length of the current initial point to the contour radius length of the previous initial point as the contour radius growth rate of the current initial point, detecting the contour initial points in sequence, and removing non-conforming points; and the satisfied points are reserved, and the points are connected to form a final cutting route. According to the invention, animal fur images with different shapes and sizes can be cut, and corresponding cutting lines are provided.

Description

technical field [0001] The invention relates to the technical field of cutting large-area animal fur outline images, in particular to a cutting method for large-area animal fur outline images based on radius increment constraints. Background technique [0002] Fur cutting is the primary processing procedure in the fur tanning industry. However, due to the heavy smell of large raw hides and the poor working environment, each cut requires 4 to 8 knives. It is easy to be physically exhausted at work, so the work intensity is high, and there is a lack of new young labor force, which makes it difficult for enterprises to recruit workers. However, the automation level of the existing technology is low, so there is an urgent need for a method that can identify the characteristics of the cutting part of a large area of ​​animal fur and give the cutting path. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of th...
