Multi-face real-time tracking based on dual panoramic camera for full-parallax light-field display

摘要

We propose a full-parallax light-field display method, based on mull-face real-time tracking with dual panoramic annular cameras. In the proposed method, the images acquired from two cameras are used to optimize the mull-face tracking method to obtain the precise spatial position of a viewer. A mull-frame refreshment mechanism is also proposed to detect whether there are new viewers in the tracking process, facilitating better interaction experience. Experiments show that our proposed method can be used to calculate the spatial position of a viewer accurately and track a maximum of seven viewpoints simultaneously such that a perfect three-dimensional display can be realized without crosstalk for viewers at different observation distances and heights.
