Synchronization-free single-shot detection of imperceptible AR markers in a high-speed video display

抄録

In this paper, we propose a method of embedding augmented reality (AR) markers in a displayed video so that they are imperceptible to human eyes. Using a high-speed projector, we display a set of markers that change their positions rapidly so that human eyes cannot perceive them, while a camera with a sufficiently short exposure time is able to detect at least one marker in the image even if there is no means of synchronization between the projector and the camera. Details of the marker design are presented.
