Abstract: Provided are an apparatus and method for managing a feature point map. The method includes generating an initial travel path through which an environmental information collecting entity moves, determining the generated initial travel path as a travel path for detection and controlling the environmental information collecting entity along the determined travel path for detection, receiving environmental information from the environmental information collecting entity, extracting feature point information from the environmental information, generating a feature point map from the feature point information, and storing the feature point map.

Abstract: There are provided a device for displaying virtual reality overlapping the real world and a method thereof. A collimated display device for augmented reality includes a virtual image providing unit configured to modulate an image of the virtual object to light and project the result; and a collimation mirror made of a translucent material that reflects light of the image of the virtual object to a user's field of vision and provides the image of the virtual object overlapping the real world. Therefore, it is possible for the user to see an image of the virtual object that is an additional image matching the real world.
Abstract translation: 提供了一种显示与现实世界重叠的虚拟现实的装置及其方法。 用于增强现实的准直显示装置包括虚拟图像提供单元，其被配置为将虚拟对象的图像调制为光并投影结果; 以及由半透明材料制成的准直镜，其将虚拟对象的图像的光反射到用户的视野，并提供与现实世界重叠的虚拟对象的图像。 因此，用户可以看到作为与现实世界相匹配的附加图像的虚拟对象的图像。
