摘要： A camera system for object recognition is disclosed. In one aspect, the system includes an active three-dimensional (3D) sensor configured to obtain a 3D point cloud which corresponds to 3D position values of an object, and a controller configured to generate control data for controlling a zoom value, a pan value, and a tilt value which correspond to the 3D position values. The system also includes a camera configured to photograph the object by performing one or more of zooming, panning, and tilting on the basis of the control data.

摘要： The present application relates to a method of representing content of an augmented reality (AR) simulator, and more specifically, to a service method for representing AR content in a simulator for a moving apparatus (an automobile, a monorail car, a cable car, a drone, etc.) according to a background. The method of representing content of an AR simulator includes recognizing AR code using background image content presented by a background screen controller and synchronizing AR content corresponding to the recognized AR code with the background image content and outputting the synchronized AR content.

摘要： Provided are a device and method for recognizing a gesture. The device includes a video image acquirer configured to acquire a video including a gesture object by photographing the gesture object, a center point detector configured to detect a center point of the gesture object in frames of the acquired video, a velocity calculator configured to calculate a velocity of the gesture object by calculating a difference between motion coordinates on each axis on the basis of the center point of the gesture object, and a gesture recognizer configured to recognize a gesture of the gesture object by comparing the calculated velocity of the gesture object with a preset velocity.

摘要： A method for inserting information into a 3D structure and recognizing information in a non-destructive method is provided. A 3D printing method according to an exemplary embodiment of the present invention includes: generating a tag having specific information recorded thereon to be inserted into a 3D structure, and printing the tag on the inside of the 3D structure while printing the 3D structure. Accordingly, since the tag having information recorded thereon is printed on the inside of the 3D structure when the 3D structure is printed by a 3D printer, it is impossible to forge/falsify information.
