报告摘要: With the development of the multimedia technology, 3-dimensional TV (3DTV) is becoming one of the main TV products in the market nowadays. 3DTV can provide a user 3D impression as if he is really over there, by displaying 3D images on the 3D display monitors of glasses/non-glasses types. There are two disadvantages for 3DTV. One is that 3D display sets themselves are much more expensive than 2D ones are. The other is that 3D videos/movies are much more expensive and difficult to shoot than 2D ones are, as more advanced equipment and techniques are needed. Even though users choose to buy a 3DTV, they have to use it as a conventional TV in most of the time due to the lack of 3D video resources. In our daily life, 2-dimensional (2D) displays are still dominated, including conventional TV sets, computer monitors, mobile phones, etc. In this situation, developing a low cost and convenient technique to support easy shooting 3D video resources, meanwhile generated 3D videos can be watched on both 2D and 3D displays with glasses, will be of significance and practice for normal users in general entrainment and family video records.
There are two steps in converting 2D videos into 3D ones, including depth map generation and depth image based rendering (DIBR). Both techniques are hot topics in computer vision. In this study, a practical depth map generation approach will be introduced, which fuses the motion estimation, color information and linear perspective information together. A multidirectional hole-filling technique in DIBR will also be introduced in this study. Combined those two steps, we can convert the 2D videos to 3D ones. This technique can be used for non-professional 3D video generation applications, including school educational purposes and family entertainments.
