Abstract

The invention discloses a region identification method and device, and belongs to the field of image processing. The region identification method comprises that a predetermined edge of a certificate in a certificate image is identified; at least one information region is determined in the certificate image according to the predetermined edge; and the information region is cut to obtain at least one character region. The problems that certain information region is hard to identify and in accurate in positioning when the certificate image is directly short in the prior art are solved, the information region is determined via the predetermined edge of the certificate image and cut, and thus, the information region is accurately positioned, and the character region in the information region is accurately identified.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an area recognition method and device. Background technique [0002] The automatic identification technology of the ID card is a technology to identify the text information on the ID card through image processing. [0003] The related technology provides an automatic identification method for an ID card. The ID card is scanned by an ID card scanning device according to a fixed relative position to obtain a scanned image of the ID card; text recognition is performed on n predetermined areas in the scanned image to obtain At least one of name information, gender information, ethnicity information, date of birth information, address information and citizenship number information. However, it is still difficult to recognize the ID card image obtained by direct shooting. Contents of the invention [0004] In order to solve the problems in related technologies, the pres...
