摘要： An apparatus and method for providing augmented reality-based realistic experience. The apparatus for providing augmented reality-based realistic experience includes a hardware unit and a software processing unit. The hardware unit includes a mirror configured to have a reflective characteristic and a transmissive characteristic, a display panel configured to present an image of an augmented reality entity, and a sensor configured to acquire information about a user. The software processing unit presents the augmented reality entity via the display panel based on the information about the user from the hardware unit after performing color compensation on the color of the augmented reality entity.

摘要： Disclosed herein are an apparatus and method for verifying and correcting degree of 3D-printed joints movement. A method for correcting a print position of a three-dimensional (3D) object is performed by a 3D object print position correction apparatus, and includes setting at least one adjacent mesh of a 3D object in which multiple shells are connected to each other through a joint structure, calculating movement degree information for the joint structure of the 3D object using the set adjacent mesh, and correcting a print position of the 3D object such that the print position matches the calculated movement degree information.

摘要： An apparatus and method for capturing a light field image. The light field image capture apparatus includes a mirror array or a micro-lens array. An activated mirror selected from among the multiple mirrors of the mirror array provides light to the multiple elements of an image sensor. An activated lens, selected from among the multiple lenses of the micro-lens array, provides light to the multiple elements of the image sensor. Based on timesharing, the mirror, selected as the activated mirror from among the multiple mirrors, is changed, and the lens, selected as the activated lens from among the multiple lenses, is changed.

摘要： Disclosed herein are a method and apparatus for matching 3D terrain information based on aerial images captured at different altitudes. The method includes receiving a high-altitude numerical height model based on a terrain image captured at a specific high altitude; receiving 3D terrain information observed from a low altitude, which is generated based on a terrain image captured at an altitude lower than the specific high altitude; generating a low-altitude numerical height model by converting the 3D terrain information into a numerical model in the same form as the high-altitude numerical height model; measuring the cross-correlation between the high-altitude numerical height model and the low-altitude numerical height model, thereby calculating matching parameters for enabling the low-altitude numerical height model to match the high-altitude numerical height model; and adjusting the geospatial coordinates of the 3D terrain information based on the matching parameters and outputting georeferenced 3D terrain information in the same coordinate system as the high-altitude numerical height model.

摘要： Method and apparatus for calibrating multiple cameras. A first mirror and a second mirror are arranged opposite each other. An object is disposed between the first mirror and the second mirror. Calibration of the multiple cameras is performed using a figure of the object formed on the second mirror via reflection from the first mirror and the second mirror.
