The invention relates to an identity card identification method and device. The method comprises steps that on the condition that a target image is determined by a first full convolutional network tocontain an ID card, a character location area of the target image is determined through a second full convolutional network; characters of the character location area of the target image are identified through a third full convolutional network; the ID card information of the target image is determined according to the characters of the target image. The method is advantaged in that the ID card information of the image can be rapidly and accurately identified.
