  • The augmented reality is a technology which expresses the information hardly obtained in the real world by synthesizing virtual objects in the real world. This study uses IR LED marker to obtain the coordination of real world for registration of virtual objects. Since the IR LED marker is inserted in target object thus it has properties of invisible markers. To realize the augmented reality, the existence of marker can be observed in camera input image. Therefore, this paper provides a method to give the properties of perfect invisible marker by using inpainting technology when realizing IR LED marker.

  • With technologies available now, there are only a few virtual objects that augmented reality content can create. So, wider application of it is limited. If people want to realize any augmented reality content, out of a vast amount of materials available as well as virtual objects, the number of virtual objects that markers can render should be made to go up along with the content. In a precedent study, IR LEDs markers render marker information following On-Off signals. The number of LEDs should be raised to render as much information as possible, subsequently leading to the problem of oversized markers. This problem can be solved by generating data signals through the blinking of LEDs. This research puts forward OOK Code algorithm that represents the mode of data transmission using the light of LEDs. The amount of information that can be rendered by a marker increases and the size of the marker gets smaller, which is a merit, when it receives data signals from light.
