1 3D Model Wan-Yu Chen NTUEE

2 Outline Introduction Motivation Method Demo

3 Introduction - 3DAV(Audio-Visual)
3D image(X,Y,Z) 2D image(X,Y only)

4 3DAV Display Method Display-Holographic 2D graphic Display
Volumetric Display 2D graphic Display This page is OK However, what display method we are using is the “2D Graphic Display” We display the 3D things onto a 2D screen by projection and camera Maybe you can add one line about this, then our display method would not be too strange Using particles in the box to display 3D model Display 3D video without stereo glasses

5 Motivation 可以看你想看的(可以選擇) :比較有互動性.(比2D好),可以看到真實的畫面

6 MPEG Extension - 3DAV Exploration Experiment
EE1 Omni-directional Video EE2 Free-Viewpoint Video EE3 Interactive Stereo Video EE4 Depth/Disparity of 3DTV Omni-directional (Panoramic) Video Free-Viewpoint Video

7 Method to get free viewpoint video
Use calibrated 2D images to reconstruct 3D model Derive free viewpoint to camera position 3D Video Applications Viewpoint to camera position You can combine this page with the next page into one page~~~ 3D 體積模型

8 Inputs 2D images(Mashimaro)
Angle 0 Angle 0 Angle 30 Angle 60 Cute Mashimaro Angle 90 Angle 120 Angle 150

9 3D model 製作---切割主角 把2D 影像中的主角的輪廓切割出來

10 Process Silhouette Extraction
Remember the word “silhouette”~~ Silhouette image Original image

11 3D model 製作—體積模型 把2D 影像的輪廓組成3D的立體體積模型

12 Voxelization(2/2) 模擬結果 切出來的3D體積模型 一開始用來切的盒子 利用2D不同方向的輪廓來切體積
The blank area above can be eliminated 模擬結果 切出來的3D體積模型 一開始用來切的盒子 利用2D不同方向的輪廓來切體積

13 3D model 製作—加顏色 加體積模型顏色

14 Add Particle color 利用2D影像的顏色貼到3D模型上 每一個3D小體積上的顏色都由2D影像決定
Left figure: Before add particle color Right figure: After add particle color
