An embodiment of the present invention provides a method for acquiring sign data of a target object. The method comprises: acquiring a 3D depth image of a target object, the depth image being a two-dimensional image with distance information, and the distance information comprising a distance between the target object and an imaging device; acquiring a graphic outline and skeleton parameters of the target object according to depth values of pixels in the 3D depth image of the target object, the depth value being a distance that is obtained according to the distance information and indicates a distance from a point on the target object to the imaging device; retrieving in a 3D model base for a 3D model matching the graphic outline and the skeleton parameters of the target object, and acquiring parameter proportions of the 3D model; acquiring at least one real size of the target object; and acquiring sign data of the target object according to the parameter proportions of the 3D model and the at least one real size. Accordingly, experience of "what you see is what you get" is provided to users. |
