EXTRACTING CARD DATA FROM MULTIPLE CARDS

摘要

Extracting financial card information with relaxed alignment comprises a method to receive an image of a card, determine one or more edge finder zones in locations of the image, and identify lines in the one or more edge finder zones. The method further identifies one or more quadrilaterals formed by intersections of extrapolations of the identified lines, determines an aspect ratio of the one or more quadrilateral, and compares the determined aspect ratios of the quadrilateral to an expected aspect ratio. The method then identifies a quadrilateral that matches the expected aspect ratio and performs an optical character recognition algorithm on the rectified model. A similar method is performed on multiple cards in an image. The results of the analysis of each of the cards are compared to improve accuracy of the data.

主权项

1. A computer-implemented method for extracting financial card information from multiple cards, comprising:
identifying, by the one or more computing devices, one or more quadrilaterals formed by a plurality of intersections of lines from an image of a plurality of cards; determining, by the one or more computing devices, a corresponding aspect ratio for each of the quadrilaterals; comparing, by the one or more computing devices, the determined aspect ratios for each of the quadrilaterals to an expected aspect ratio, the expected aspect ratio being based at least in part on a type of card represented in the image; identifying, by the one or more computing devices, one or more particular quadrilaterals that match the expected aspect ratio; and performing, by the one or more computing devices, an optical character recognition algorithm on each of the particular quadrilaterals to extract financial card information from each quadrilateral.
