A self-reconfigurable camera array

Cha Zhang, Tsuhan Chen
2004 ACM SIGGRAPH 2004 Sketches on - SIGGRAPH '04  
This paper presents a self-reconfigurable camera array system that captures video sequences from an array of mobile cameras, renders novel views on the fly and reconfigures the camera positions to achieve  ...  Such camera reconfiguration naturally leads to a nonuniform arrangement of the cameras on the camera plane, which is both view-dependent and scene-dependent.  ...  Conclusions We have presented a self-reconfigurable camera array in this paper.  ...
