2D 3D the automatic 3D modeliing method using 2D facial image

摘要

The present invention relates to a method for generating a 3D model from a 2D image, and more particularly, to a method for automatically generating a 3D model from a single two-dimensional frontal face photograph using a technique capable of easily generating a 3D model .A method for automatically generating a 3D model from a 2D face image,(102) converting a color image to a gray image, detecting (103) a face from the gray image converted from the step, detecting (104) eye concealment on the detected face, A method comprising: executing a filter (105); detecting an edge in a gray image (106); separating foreground and background from edge information detected in the step (110); distributing a foreground vertex Step 111: Computing the front and back three-dimensional vertices from the distributed vertices 107, creating a rear partial surface 108, and calculating the front vertex calculated in the step 107 in the step A step 109 of resetting the front partial vertex using the information extracted in steps 103, 104, and 105, and a step 109 of generating a front partial surface using the vertex information calculated in step 109 And a step (112) of creating a final 3D model using the information generated through the steps (113) and all the steps.In addition, the present invention may further include calculating (107) the forward and backward three-dimensional vertices from the distributed vertices,(CenterX, centerY) of the image in each of the imaginary horizontal lines and calculates the vertex coordinate V (V) of the three-dimensional model corresponding to the coordinate (x, y)_X,V_Y, V_Z) Of the 2D facial image. The 3D model is automatically generated from the 2D facial image.The present invention also includes the steps of resetting the forward partial vertex (109)V_Z= V_Z+ I (x, y) / G_MaxAnd the 3D model is automatically calculated from the 2D face image.;
