Embodiment approach

[0103] After obtaining the image displayed by the host device, the image identification code contained in it can be detected and located by scanning the entire image. In order to improve the processing speed of this process, this application provides a preferred implementation for the case where the image identification code is a rectangle. method, that is: first detect the rectangular area in the current image, and then detect whether there is an image identification code for each rectangular area, thereby avoiding scanning in the entire image, which can effectively improve the performance of the method provided by this application, and is relatively fast to detect the image identification code.

[0104] By analyzing the acquired image, according to the characteristics of the four straight sides and four right angles of the rectangle, the rectangular area can be detected from the acquired image. In this embodiment, Hough transform is used to detect rectangular regions.

Abstract

The invention discloses a method and a device for acquiring an image identification code displayed by host equipment. The method for acquiring the image identification code displayed by the host equipment includes that acquiring an image displayed by the host equipment; detecting and locating an image identification code region in the image; analyzing the image in the image identification code region to acquire the content of the image identification code. The method for acquiring the image identification code displayed by the host equipment is capable of simplifying the operation steps of an existing scanning method and quickly and directly acquiring the image identification code displayed by the host equipment so as to be convenient for a user to use.

Description

technical field [0001] The present application relates to the technical field of image recognition, and in particular to a method and device for obtaining an image recognition code displayed by a host device. Background technique [0002] Barcode and two-dimensional code technology, born with the development and application of computer and information technology, is a new technology that integrates coding, printing, identification, data collection and processing, and is the most economical and practical automatic identification so far. technology. [0003] Among them, a barcode (also called a one-dimensional barcode) is a graphic identifier for expressing a set of information by arranging multiple black bars and blanks with different widths according to certain coding rules. The one-dimensional barcode is only in one direction (generally The two-dimensional code technology that is widely used at present is a new generation of barcode that uses specific geometric figures to ...
