The invention discloses a method for digitalizing a cutting template, comprising the following steps of: marking parameters for a camera device of a measuring system to obtain internal parameters; utilizing the camera device to obtain an original image of a background and performing imaging correction and/or distortion correction and gray processing on the image to obtain a background gray image; putting a plane reference object with known area in the background, imaging the plane reference object, performing imaging correction and/or distortion correction, gray processing, differential operation and binary processing on the image to obtain nonzero pixels of an binary image of the plane reference object, and obtaining pixel equivalence of the measuring system; putting an object to be measured in the background, and obtaining nonzero pixels of an binary image of the object to be measured; transforming an binary image of the cutting template into an edge profile image of the cutting template; and according to pixel equivalence of the digitizing system of the cutting template, transforming the edge profile image of the cutting template into a vector image of the cutting template.
