Abstract
The setting structure of pattern image-taking range is mainly used for defining image-taking range on a carrier, on the carrier at least the following portions are distinguished: the image-taking range information part is used for generating image-taking shape and relative size information which takes the positioning part as a reference and extends to each peripheral side from the reference, so as to form an image-taking range at least comprising the image sample area.
Description
Technical field
The invention relates to the setting structure of pattern capture scope, particularly relates to one kind and is easy to distinguish regarding operation, can be effective
Simplify capture program, the setting structure of the overall pattern identification efficiency of lifting.
Background technology
Fluorescent fibre image is effective anti-fake label a kind of in recent years, and it is by the way that fluorescent material stained with chemical fine
Tie up on carrier, and this fluorescent fiber is added in paper pulp according to certain ratio in paper-making process and is made.False proof
In labeling identification process, the image containing rectangle frame is picked up by imaging sensor, the region in rectangle frame is fluorescent pars fibrosa, institute
Positioning and segmentation with rectangle frame are to identify the first step of anti-counterfeiting information.Generally, the localization method of pending image has two kinds：
One kind fits for straight line, i.e., fits straight line by some points of scan image, obtains linear equation, forms rectangle, but such a side
The situation of rectangle frame boundary fault occurs in method；Another kind is using projection, but such a method is dry to having outside rectangle frame in image
Disturb, it is difficult to obtain linear equation exactly, and then be difficult to obtain required rectangular image.In addition, picked up by imaging sensor
After taking pending image, geometric distortion will usually occur for real rectangle frame, become in general quadrangle, so as to be difficult to lead to
Cross rectangle to define to carry out the positioning of target image, and position with partitioning algorithm to different application environments, including background, color
Difference there is no good adaptability yet.Therefore, prior art is bad to the recognition capability of anti-counterfeiting information.
Therefore, it is to disclose CN 1794267A just like China " to be used to rectangle frame in anti-counterfeiting information identification process position
Method " patent of invention case produces, and it comprises the following steps：Pending image containing rectangle frame, square are picked up by imaging sensor
Region in shape frame is the pars fibrosa for anti-counterfeiting information identification；Marked in pending image a bit, be referred to as interior point；It will wait to locate
Manage image and carry out image binaryzation processing；Since the interior point of pending image, it is scanned, edge point set is formed, to edge
Point set carries out lines detection, forms a quadrangle；Geometric correction is carried out according to quadrangle, forms rectangle frame.To pending image
Binary image processing is carried out, avoids background, the difference of color to framing and the influence of segmentation, moreover, from pending figure
The interior point of picture proceeds by scanning, obtains edge point set, and carries out lines detection to edge point set and obtain quadrangle, reduces image
Outside interference, in addition, carrying out geometric correction according to quadrangle, the quadrangle of generation geometric distortion is set to form rectangle, it is reliable to know
Other anti-counterfeiting information.
However, above-mentioned such a positioning method still has complicated determining program, and substantial amounts of numerical operation, can not only consume
Take the calculation resources of data processing unit, also influence the efficiency of data processing, economic benefit is not met in practical application yet.
And in current application form, on foregoing Anti-forgery reeling mark in addition to security pattern and sign, also there is display two
The structure of bar code is tieed up, but this two-dimensional bar is all to provide logistics（Transport, storekeeper）The logistics code of message, and there are no
By the two-dimensional bar（Logistics code）Assign other functions related to capture or pattern recognition.
In view of common by having above-mentioned inconvenience during acquirement security pattern on Anti-forgery reeling mark, inventor is to be directed to
The road of those shortcoming Improvements, there is the generation of the present invention finally.
The content of the invention
