Abstract
A method for generating a personalized 3D model using a plurality of 2D images and a generic 3D model is provided. The method includes the following steps: extracting a plurality of feature points from the plurality of 2D images; extracting a plurality of landmark points from the generic 3D model; mapping the plurality of features extracted from the plurality of 2D images to the plurality of landmark points extracted from the generic 3D model so as to generate relationship parameters for a mapping algorithm; morphing the generic 3D model into a personalized 3D model with the plurality of landmark points, the relationship parameters and the mapping algorithm; iteratively refining the personalized 3D model with the plurality of feature points extracted from the plurality of 2D images; and when a convergent condition is met, the step of iteratively refining the personalized 3D model is complete and the personalized 3D model is saved to the 3D model database.
