Picture recognition method and device

Abstract

The embodiment of the invention provides a picture recognition method and device. The picture recognition method comprises the steps: scanning a to-be-recognized picture, and obtaining a first image region of a pixel point belonging to a target object according to the pixel value of each pixel point in the to-be-recognized picture; according to the first image area, obtaining a second image area in the to-be-identified picture, wherein the second image area comprises the first image area; obtaining an image area of the target object according to the first image area and the second image area;setting the position of the image area of the target object in the to-be-identified picture as a target position; and identifying related information of the target object according to the image area of the target object after the target position is set, wherein the contour vertex of the target object in the image area of the target object is located on the contour of the second image area. Accurate positioning of the position of the target object on the to-be-identified picture is realized, so that the position of the information on the target object picture is accurately positioned, and the accuracy of information identification on the target object picture is improved.

[0003] However, some departments input ID card information through ID card pictures (for example, copied ID card pictures). The ID card picture contains a lot of background text (that is, non-ID card information), which will lead to inaccurate positioning when positioning the text lines on the ID card picture, and affect the accuracy of ID card recognition.
