How to match and interact with virtual reality space and real space

It scans the world around you to gather information and merges the real and virtual worlds to create mixed reality. By placing virtual objects on the collected images, the virtual 3D stereoscopic image appears as if it were actually in space. Through 3D spatial mapping using a sensor that can extract depth values, 3D images can be visualized realistically and naturally, and it is used in various solutions such as VARLOS and Smart Worker.

Spatial Mapping refers to the process of mapping a real surface to a virtual world, and this feature enables realistic interactions between virtual content and reality. In order to naturally place virtual objects in the mapped space, a device equipped with a sensor function that can extract depth values scans the limited surrounding space and maps the three-dimensional space by extracting position and depth values.

To measure the mapping error through vector operation, a virtual marker is created based on two markers placed in reality using a device that can extract depth values, and the Extract the coordinates. When extracting the coordinates of markers from the virtual environment, it is necessary to map them to the real coordinate system for comparison. The value of the extracted location information measures the straight line distance between markers through vector operation and calculates the error between the virtual measurement distance and the real measurement distance.

Indoor positioning for setting up a virtual reality experience space  recognizes a location in real space using a device that can extract position and rotation values including depth. Position a device equipped with a location-tracking sensor, compare the location of the real sensor with its location in virtual space, and set the scope of the playground for a safe VR experience.

Posture recognition using motion sensors compares real posture with posture in virtual space. The position and direction are extracted from each attached sensor by wearing the sensor-attached posture recognition device on the area to recognize the posture (upper/lower body) and moving a part of the joint. It can be seen that the posture of the avatar is changed in the changed 3D virtual space according to the extracted information.
