説明
We present a method for detecting on-screen markers to identify physical displays and to estimate camera poses against these displays. It is difficult for humans to perceive the variation of two alternating colors when these colors switch in a frequency higher than the flicker fusion threshold. On the other hand, the variation is detectable by of-the-shelf rolling shutter cameras which have certain frame rate setting. Leveraging on the difference between the human visual characteristics and the camera characteristics, imperceptible markers can be embedded onto a display screen. In this paper, we introduce our technique in mobile device based user interfaces for manipulating digital content on large distributed displays. Furthermore, we show that our prototype system enables an augmented reality application on a mobile device using the marker embedded displays. Lastly, we discuss potential scenarios and applications.
