Abstract

The invention discloses an area extraction method and device, belonging to the image processing field. The area extraction method comprises: obtaining the area position of a first information area in a certificate image; determining a second information area according to the area position of the first information area; and obtaining at least one character area through dividing the second information area. The method and device solve the problems of large difficulty in recognizing certain information area in a directly shot certificate image, and inaccuracy of certain information area positioning, determine the second information area according to the area position in the first information area in a certificate image, and divide the second information area, thereby accurately positioning the second information area, and identifying the character area in the second information area.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular to a region extraction 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 existing in related technologies, the...
