A system and method for supporting augmented reality in an ocean scene is provided. According to the system and method, camera rotation information is extracted from horizontal line information of a sea extracted from an original image including a focal length and at least two first natural feature point tracking data existing on a sea plane and a plane parallel to the sea plane, using long-distance background features; camera movement is sequentially calculated from the camera rotation information and at least two natural feature point tracking data existing on the sea plane of the original image; and a computer graphics object is placed on a ground plane by importing camera position data, and a rendering is performed as moving the camera. Accordingly, the camera rotation and the camera movement can be accurately calculated, assuming that the camera focal length information is known at the time of capturing a moving image with a sea image for a background, and thus the CG/real scene synthesis with the sea for a background can be accomplished more realistically and accurately during the production of videos such as movie and drama.

A system for simulating NAT (network address translation) performed in an internet protocol (IP) sharing device to be selectively operated in one of different network address translation (NAT) schemes includes a first network interface linking the IP sharing device with an internal network and a second network interface linking the IP sharing device with an external network. A Network Driver Interface Specification (NDIS) interface hooks packets incoming to the external network or outgoing from the internal network. A NAT unit has a mapping table and performs a network address translation of the hooked packets with reference to the mapping table, wherein the mapping table identifies IP addresses and port numbers of the packets to be translated by the NAT unit.

Provided is a mouse interface apparatus using a camera, and system and method using the mouse interface apparatus. The mouse interface apparatus detects image coordinates (xi, yi) of a plurality of points existing on edges of a camera-photographing computer window image from the camera-photographing computer window image, obtains a homography using the detected image coordinates (xi, yi) and plane coordinates (Xi, Yi) of the plurality of preset points on a plane of a real computer window, the homography converting the detected image coordinates (xi, yi) into the plane coordinates (Xi, Yi) on the real computer window, converts an arbitrary coordinate on the camera-photographing image into the plane coordinate on the computer window according to a movement of the camera using the obtained homography, and positions a cursor on the plane coordinate to move the position of the cursor according to the movement of the camera.

A high-speed marker-free motion capture, which is capable of powerfully detecting a body's feature points corresponding to a body's end portions such as a head, hands, feet, trunk, arms and legs at a high speed in an illumination change or background or noises of cameras. The extracted feature points of the body can be directly tracked stably in a 3-dimensional space. The position errors of the feature points due to the change of the illumination conditions or a shadow can be automatically corrected and the feature points can be stably tracked with respect to overlapping and disappearance of the feature points. Further, when coordinates of the middle joints are estimated using 3-dimensional coordinates of the extracted feature points of the body, the present invention restores a human model by estimating the positions of the middle joints of the actor with high accuracy without using a motion database, thereby securing the stability and reality of the 3-dimensional motion data required in the motion capture.

Disclosed herein is an apparatus for collecting game data in order to test performance of a game server. The apparatus includes a capture and filtering module, a control module, and a data management module. The capture and filtering module captures packets, transmitted and received between the game server and each of a plurality of game clients, using the plurality of game clients, and extracts a plurality of necessary data by performing filtering on the results of the capturing. The control module determines the movement route of a game character in such a way as to correspond to the plurality of necessary data, and controls the plurality of game clients based on the movement route. The data management module stores and manages the plurality of necessary data.
