The present invention relates to a head mounted display installation structure for augmented reality. More specifically, the present invention relates to an installation structure in which a head mounted display is installed in an exhibition room or the like for viewing augmented reality.

In general, augmented reality means that a virtual object created by graphics is inserted into a video image captured by a commercial video camera to match the motion of the video camera. It's a technique that makes you appear. Recently, with increasing interest in augmented reality, augmented reality has been studied by many researchers. Application methods in various fields have been studied, and technologies for development are also developing. The development of hardware and software for augmented reality has been applied to a wider field.

On the other hand, many modeling software exists for modeling, and the modeling work was performed using such software. However, many modeling softwares presented in the related art can be used only when the expertise with many repetitive uses and trainings is acquired. There was a problem that is difficult to do.

In general, virtual reality includes Immersive VR, Desktop VR, and Augmented Reality. Among them, augmented reality is a computer-generated image that is generated by a user in a realistic image It is a user interface technology that accurately matches virtual images. Through this augmented reality it is possible to provide a user with improved realism and awareness.

In order to implement such augmented reality, accurately estimating the motion of a camera or a tracking object is an important core technology, and the method of implementing the augmented reality is generally divided into two methods. The first is the use of feature points collected from objects in the real world, which is the ultimate approach in augmented reality, but still has poor performance when there is little feature point information collected from objects or unstable environmental conditions such as lighting. There is a disadvantage that greatly falls. The second is to use a marker known in advance, which generally has a stable performance compared to the former.

Vision-based augmented reality device using such a marker will be described with reference to FIG. 1 is a block diagram of a conventional vision-based augmented reality device. The conventional vision-based augmented reality device shown in FIG. 1 includes an imager 11 for photographing a tracking object TO having a visible marker VM and a marker image displayed on the tracking object by the imager 11. An image processor 12 for monitoring the position of the marker in the image based on the position and direction of the tracking object, and rendering a virtual image prepared in advance in the tracking object image to generate a new image; An output device to display device 13 for outputting the image from the image processor 12 to the screen.
