The method is characterized by comprising the following steps: (1) setting a photographing device, wherein the photographing device comprises a 180-degree wide-angle lens; the lens is positioned on one side of the large-sized plane advertising board, facing towards the advertising board and photographing contents on the advertising board; (2) adjusting the angle between the lens and the advertising board so that all contents on the advertising board can be photographed; (3) photographing an instant image of the advertising board by the photographing device, and then performing distortion correction processing on the photographed image to normalize the photographed image so as to finish the photographing of the large-sized plane advertising board at the time. The invention also discloses a photographing construction of the large-sized plane advertising board formed by the method. By using the 180-degree wide-angle lens, the advertising board can be photographed with high definition at a short distance; in order to overcome the defect of image distortion produced by the wide-angle short-distance photographing, an image processing step is specially designed to perform the distortion correction processing on the photographed image so as to normalize the image.
