Abstract: A method for transmitting virtual reality (VR) content by a device is provided. The method includes obtaining at least two images captured from a target, arranging the at least two images and projecting the at least two images onto a planar surface to configure a 360-degree image corresponding to the VR content, detecting an overlapped region of the at least two images projected and generating rearrangement information about the overlapped region, and transmitting the rearrangement information and the at least two images.

Abstract: The present invention relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present invention can be utilized for intelligent services (smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) based on the technology. The present invention relates to an efficient image processing method and device for virtual reality content, and according to one embodiment of the present invention, the image processing method for projecting an image of virtual reality content comprises the steps of: acquiring a first planar image projected by dividing a front part and a rear part of a spherical image for expressing a 360-degree image; generating a second planar image projected by sampling the first planar image on the basis of a pixel position; and encoding the second planar image.

Abstract: Methods and apparatuses are provided for transmitting information about an omni-directional image based on user motion information by a server. Motion parameters are received from an apparatus worn by a user for displaying an omni-directional image. User motion information is generated based on the received motion parameters. First packing information corresponding to a user position is generated based on the user motion information. Second packing information corresponding to a position in close proximity to the user position is generated based on the user motion information. Third packing information is generated based on the first packing information and the second packing information At least one of the first packing information, the second packing information, and the third packing information is transmitted to the apparatus.
