Embodiment Construction

[0080] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0081] The purpose of the present invention is to automatically generate a three-dimensional human face model according to a person's photo retrieved from a mobile phone through a method for automatically converting a single frontal photo of a human face into a three-dimensional model.

[0082] The present invention is realized through the following technical solutions: the method is mainly applied to the automatic extraction module of the face feature points of the picture, the standard three-dime...

Abstract

The invention provides a method and a system for generating a 3D model by calling a picture from a mobile phone photo album. The method comprises the following steps: obtaining an image from a mobile device, and carrying out face detection to the image; regulating a face; determining face feature points in the image; generating a model chartlet; and cutting the face in the model chartlet according to a facial form outline, and adding the cut face onto a specified position of a three-dimensional face model M2. Compared with the prior art, the invention has the beneficial effects that a figure picture called from a mobile phone can be automatically converted into a three-dimensional feature facial form, and the invention has the advantages of being easy in implementation and high in conversion speed.

Description

technical field [0001] The invention relates to the field of three-dimensional character generation, in particular to a method and a system for generating a 3D model by retrieving photos from a mobile phone album. Background technique [0002] In the existing 3D face shape change technology, the methods of 3D reconstruction are different. A 3D laser scanner can be used, or a set of 2D images can be used to generate a 3D model. 3D laser scanner technology requires complex equipment and has certain limitations on the size of physical objects. The equipment needed to take pictures in 2D images is simple, and there is no limitation on the size of physical objects that 3D scanners face when shooting outdoor scenes, but the algorithm of this method is complex. At present, photos are used to restore the spatial entity model by using the principle of perspective imaging, and the optical center of the camera is used as the observation point, and the object on the photo is the projec...
