Mixed Reality Content Providing Device with Coordinate System Calibration and Method of Coordinate System Calibration using it

摘要

The present invention relates to a mixed reality content providing device with an automatically correctable coordinate system and an automatic coordinate system correcting method using the same, capable of automatically correcting two coordinate systems so that a coordinate system of a projection area, projected by a beam projector, is matched with a coordinate system of a depth camera. According to an embodiment of the present invention, the mixed reality content providing device includes: a beam projector projecting a beam for limiting a user′s motion area; a depth camera recognizing a motion of the user; and a data processing part generating a mixed reality image by analyzing the user′s motion recognized by the depth camera, and then, transmitting the generated mixed reality image to the beam projector. The data processing part extracts an image area from a floor image, formed by the beam projected from the beam projector, and obtains projection area coordinate information from the extracted image area, and then, compares the obtained projection area coordinate information with preset reference coordinates of the depth camera to correct the reference coordinates of the depth camera with the projection area coordinate information if the reference coordinates of the depth camera are different from the projection area coordinates.
