Embodiment Construction

[0022] As we all know, the commonly used algorithms for edge point detection can include Sobel algorithm, Prewitt algorithm, Roberts algorithm, Krich algorithm, Canny algorithm, etc. Although the performance of different algorithms is different, no matter which algorithm is used for edge detection, the detected edge There are fractures in the contours obtained by point connection. In order to solve the problem of contour fracture, the technical solution of the embodiment of the present invention is proposed.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creati...

Abstract

The invention discloses a contour connection method. The method comprises: looking for a fractured contour from basic contours; by taking one of fractured edge points of the fractured contour as a target edge point, calculating a distance between each of other fractured edge points and the target edge point; when the distance between each of the other fractured edge points and the target edge point is smaller than a preset threshold, determining the position of connection between the fractured edge point and the target edge point; calculating an angle difference between a virtual contour and the fractured contour; and when the angle difference between the virtual contour and the fractured contour is less than a preset angle threshold, connecting the target edge point with the fractured edge point. The invention furthermore discloses a contour connection apparatus. Compared with the prior art, the technical scheme provided by embodiments of the invention has the characteristics that the fractured edge points belonging to the same contour can be screened out through distance and angle parameters after the basic contours are obtained, and the fractured edge points belonging to the same contour are connected, so that the complete contour can be obtained.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a contour connection method and device. Background technique [0002] Image inspection, as an efficient automatic inspection method, detects the nature or defects of the target through the identification and analysis of the pixel distribution, brightness and contrast of the target image. Generally, after the image detection software receives the image, it first determines the outline of the image, and then determines the area contained in the image through the outline. Among them, the contour of the image is composed of edge points. Therefore, in related technologies, the edge points in the image are first detected, and then the edge points are connected to obtain the contour. [0003] Commonly used algorithms for edge point detection can include Sobel algorithm, Prewitt algorithm, Roberts algorithm, Krich algorithm and Canny algorithm. Among them, because the detecti...
