Problems solved by technology

[0003] In order to solve the technical problem of insufficient accuracy of current fingerprint deduction, the present invention provides a method for on-site subway payment, which determines whether the fingerprint deduction operation can be performed based on the angle at which the identified fingerprint outline deviates from the vertical plane, and if the angle reaches a preset range The fingerprint checkout operation is allowed at the time, otherwise, on-site reminders are 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 sharp detection mechanisms are also designed for images. And on the basis of sharp detection, the image frequency domain processing mode 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 invention relates to a metro field payment method. The method comprises: using a metro field payment system to carry out field payment. The metro field payment system comprises a fingerprint extracting device arranged on a metro payment manipulating device, which is used for collecting fingerprint images of a bill settlement requestor to output corresponding payment fingerprint images. A liquid crystal display screen is arrange on that metro pay manipulation device, and is used for perform on-site display on the deviation angle when the deviation angle is received; a gray level analyzing device connected with the fingerprint extracting device, configured to receive the paid fingerprint image, detect a gray level balance degree of the paid fingerprint image to obtain a current balance degree corresponding to the paid fingerprint image, and output the current balance degree corresponding to the paid fingerprint image.

Description

technical field [0001] The invention relates to the field of fingerprint fee deduction, in particular to a method for on-site subway fee payment. 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, and 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 fingerprint feature...
