This paper proposes a method of embedding AR (augmented reality) markers in a high-speed video sequence so that they are imperceptible to human eyes. The embedded markers appear for very short periods and keep changing their positions at lightning speed. By carefully designing the timings of marker display, a camera with a sufficiently short exposure time running at any frame rate is able to detect at least one marker in the image even if there is no means of synchronization between the display and the camera. Experimental results show that different types of markers such as 2D barcode markers and spatially distributed markers are able to be used with the proposed method.
