We have developed omnidirectional-view 3D displays using multiple mini-projectors. Three types of synchronization structure are developed to ensure the accurate synchronization between the projectors and the rotating screen. Therefore, low-cost and low-speed display devices can be used to realize natural-looking three-dimensional (3D) scene with full color and high resolution.
This paper introduces a novel augmented reality shooting game named “Soul Hunter”, which has been successfully operating in a theme park in China. Soul Hunter adopts an innovative infrared marker scheme to build a mobile augmented reality application in a wide area. It is an extension of the traditional first person game, in which a player is able to fight with virtual ghost through a gunlike device...

We propose a novel local feature descriptor named Enhanced Point Descriptor (referred to as EPD) for dense stereo matching applications. The existing local feature descriptors, e.g., SIFT and SURF, can only be used to represent sparse image extreme points which make stereo matching sparsely. We design EPDs to represent common image points. To generate an EPD, we first build image characteristics vectors...
In this paper, we propose a real-time and adaptive method for labeling and recognition of multiple infrared markers. A single-frame based iteration process is developed to obtain the suitable threshold. A sliding window is proposed to propagate the preliminary labels and to reduce the capacity of equivalent tables handling. The labeling and recognition are realized by merging the results of domains...
