High-speed photographing instrument voucher intelligent edge cutting and correcting system and high-speed photographing instrument voucher intelligent edge cutting and correcting method based on silhouette extraction

Abstract

The invention discloses a high-speed photographing instrument voucher intelligent edge cutting and correcting system based on silhouette extraction. The high-speed photographing instrument voucher intelligent edge cutting and correcting system based on silhouette extraction comprises a high-speed photographing instrument camera (1), a high-speed photographing instrument light supplementing lamp (2), a display (3) and a processor (4) with an image edge cutting and correcting function, wherein the high-speed photographing instrument camera (1) is used for acquiring voucher images in a video; the high-speed photographing instrument light supplementing lamp (2) is used for improving brightness under the condition that an external environment is dark; the high-speed photographing instrument camera (1) and the high-speed photographing instrument light supplementing lamp (2) are connected with the processor (4) with the image edge cutting and correcting function; the voucher images which are acquired by the high-speed photographing instrument camera (1) are subjected to edge cutting and correction treatment by the processor (4); and the display (3) is connected with the processor (4) and is used for displaying a processing result of the processor (4). By the high-speed photographing instrument voucher intelligent edge cutting and correcting system, manual operation is not required; and the anti-interference property and the adaptability of the voucher bill edge cutting method are improved.

Description

technical field [0001] The invention relates to a contour segmentation-based intelligent edge trimming and correction system for Gaopaiyi vouchers and a method for edge trimming and tilt correction of voucher images using the system, belonging to the field of digital image processing. Background technique [0002] Bank certificates are divided into two categories: important certificates and common certificates. Important vouchers mainly refer to the bills (such as deposit certificates, passbooks, money orders, checks, etc.) and cards (such as debit cards, credit cards, etc.) used in financial activities, and ordinary vouchers mainly refer to the documents used to record financial activities, such as general bookkeeping vouchers , financial documents, etc. With the widespread and frequent use of financial certificates in financial transactions, and the variety of financial certificates, the demand for trimming and tilt correction of image information of financial certificate...

AI Technical Summary

Problems solved by technology

For example, using manual screenshot-style trimming requires manual calibration of boundaries. This method not only consumes a lot of time and human resources, but also generates errors due to the operator's subjective placement of vouchers and subjective selection of boundaries.

Another example is the edge trimming method based on the Hough transform and the edge trimming method based on a rectangle. These two methods are relatively mature and stable in theory, but the edge trimming method based on the Hough transform can only be used to find linear boundaries and has poor anti-interference ;The rectangle-based edge trimming method can only be used to find the rectangle boundary, and has poor adaptability

[0004] The main disadvantages of these methods are low efficiency, low accuracy, poor anti-interference and adaptability, and cannot well meet market demand.
