Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] In the embodiment, the reference printed matter and the first printed matter to be matched (actually matched) and the reference printed matter and the second printed matter to be matched (actually not matched) are compared and illustrated. Such as figure 1 As shown, a kind of local line segment deviation degree feature matching method based on printed matter provided by the present invention comprises the following steps:

[0046] Step 1: Perform linear deviation feature extraction on the image parts of the reference printed matter, printed matter 1 to be matched, and printed matter 2 to be matched respectively;

Abstract

The invention discloses a local line segment degree of deviation feature matching method based on a printed matter. The method comprises steps of extracting a line segment degree of deviation feature of the printed matter; performing matching method by using a minimum superposed length and a symbol difference; and determining the local matching relation of the printed matter according to a line segment matching result. The method solves a matching problem between different length features and prevents incapable matching and distance errors due to line segment position point inaccuracy.

Description

technical field [0001] The invention relates to image processing technology, in particular to a feature matching method based on printed matter of partial line segment deviation. Background technique [0002] Image feature extraction and feature matching has always been the focus and hotspot in the field of image processing, and is one of the key steps in image registration, image fusion and other related fields. Image features mainly include point features, line features and surface features. Image matching is mainly divided into two categories: feature-based and grayscale-based. [0003] At present, among feature-based matching schemes, SIFT-based feature extraction and matching algorithms are most widely used. It can handle translation, rotation and scale changes well, but for parts of prints with few point features, the matching effect is not satisfactory. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a ...
