Problems solved by technology

[0003] In order to solve the technical problem of insufficient accuracy of current fingerprint deduction, the present invention provides an instant payment system based on fingerprint collection, which determines whether the fingerprint deduction operation can be performed based on the angle at which the recognized fingerprint outline deviates from the vertical plane, and when the angle reaches the predetermined Fingerprint checkout operations are allowed only when within the set range, otherwise, on-site reminders will be provided, which improves the efficiency of subway on-site payment, reduces the number of subway management personnel, and saves the operating expenses of the subway management side; at the same time, a set of targeted and sharp images are designed detection mechanism, and on the basis of sharp detection, the frequency domain processing mode of the image is customized to improve the effect of image frequency filtering

Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Fingerprint extraction is a precision electronic instrument that uses the different characteristics of human fingerprints for identification. Its working principle includes four functions: collecting fingerprint images, extracting fingerprint features, saving data and comparing fingerprints. Among them, reading the fingerprint image is the most basic and important function of the fingerprint collector. Imaging is performed by using the uneven pattern of fingerprints. Usually, we call the convex pattern "ridge", and the concave pattern is called "valley". The process of fingerprint collection is essentially the process of fingerprint imaging. process.

[0018] The principle is to obtain different optical or current resistance feedback signals according to the geometrical, physical and biological characteristics of ridges and valleys, and use diffe...

Abstract

The present invention relates to an instant payment system based on fingerprint collection. The system includes: a fingerprint extraction device, which is arranged on a subway payment control device, and is used to collect the fingerprint image of a checkout requester to output a corresponding payment fingerprint image; a liquid crystal display The screen is arranged on the subway payment control device, and is used for on-site display of the deviation angle when receiving the deviation angle; the grayscale analysis device is connected with the fingerprint extraction device, and is used to receive the payment fingerprint image, Detecting the gray balance degree of the payment fingerprint image to obtain the current balance degree corresponding to the payment fingerprint image, and outputting the current balance degree corresponding to the payment fingerprint image.

Description

technical field [0001] The invention relates to the field of fingerprint deduction, in particular to an instant payment system based on fingerprint collection. Background technique [0002] Fingerprint extraction includes the center (upper, lower) and triangular points (left, right), etc. The detailed feature points of the fingerprint mainly include the starting point, ending point, joint point and bifurcation point of the ridge line. Extract the feature point information (terminal point, bifurcation point...) of the fingerprint from the preprocessed image. The information mainly includes parameters such as type, coordinates, and direction. The detailed features in the fingerprint usually include endpoints, bifurcation points, isolated points, short forks, rings, etc. The ridge line endpoints and bifurcation points have the most opportunities to appear in fingerprints, are the most stable, and are easy to obtain. These two types of extraction points can match the fingerpri...
