Abstract: A method for acquiring information of a foot, the method includes: acquiring an image captured by simultaneously photographing a user's foot and an item having a standardized size; and calculating information of the user's foot from the image. The calculating the information of the user's foot from the image includes: calculating positions of vertices of the item from the image; and calculating a region where the user's foot is located in the image. The calculating the positions of the vertices of the item from the image includes: calculating one or more feature points corresponding to a corner in the image; and selecting the vertices of the item among the one or more feature points, and the one or more feature points are calculated by using brightness values of pixels in the image.
