Image-Based 3D Photography and Video Technology

三維攝影及影像技術


Image-Based Rendering is an emerging and promising technology for rendering new views of real-world and synthetic scenes from a collection of densely sampled images. It opens up new opportunities for developing revolutionary virtual reality and visualization systems such as 3D photography, video and television systems. Other important applications include cultural heritage preservation, computer vision and intelligence, etc.

基於圖像的繪制技術是一項被受廣泛關注的科技。此技術是通過拍攝一系列真實或虛擬場景的圖片或影像，重新繪制出不同及新的視點。對於在革命性發展的虛擬現實與視覺系統，例如三維攝影、三維影像和三維電視等，起着關鍵的作用。此外，這項技術亦可應用在文化保育、計算機視覺與人工智能等重要領域。


Examples:


Snapshots of an 8 camera-based plenoptic video.
 
 


Example of a concentric mosaic. Using the concentric mosaics, new views of the scene can be rendered at very high quality.

  
   
 
   

Some of the rendered views of the concentric mosaics.
Some of the renderings of the plenoptic video at different time instants. This dynamic representation is the generalization of traditional videos to support immersive viewing.
