Embodiment 1
[0066] figure 1 It is a process schematic diagram of a method for extracting ID card information provided by an embodiment of the present invention, and the process includes the following steps:
[0067] S101: Based on the pre-trained deep learning network model, determine the information of the area where the ID card number is located in the input ID card image.
[0068] The ID card information extraction method provided by the embodiment of the present invention is applied to an electronic device with an image acquisition function, such as an image acquisition device, or a smart phone, a PC, a server, a tablet computer, and the like.
[0069] In the embodiment of the present invention, in order to extract the ID card information in the ID card image, it is first necessary to obtain the ID card image. card image.
[0070] After the electronic device obtains the ID card image, it processes the ID card image based on the pre-trained deep learning network model to determine th...
Embodiment 2
[0089] In order to determine the area where each character is located in the area where the ID card number is located, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, according to the area where each character is located in the area where the ID card number is located, determine the area that contains all characters. Before the subregion of the region where each character is located, the method also includes:
[0090] Carry out binarization processing to the pixel points in the area where the ID card number is located, and determine each connected domain in the area where the ID card number is located according to the pixel value of each pixel point after the binarization processing, and divide each connected domain The above connected domain is determined as the area where each character is located.
[0091] After determining the information of the area where the ID card number is located in the ID card image, in order to determine...
Embodiment 3
[0095] In order to determine each connected domain in the area where the ID card number is located, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, according to the pixel value of each pixel after the binarization process, determine the Each connected domain within the area where the ID number is located, including:
[0096] According to the pixel value of each pixel point after binarization processing, determine each target pixel point whose pixel value is the set pixel value;
[0097] For each target pixel, determine each first point set consisting of the target pixel and other target pixels adjacent to the target pixel;
[0098] For each first point set, if there are other first point sets having the same target pixel as the first point set, the first point set is updated based on other first point sets having the same target pixel, Until other first point sets do not have the same target pixel as the updated first point set;
