摘要:
An apparatus and method for processing a virtual world. According to certain embodiments of the present disclosure, real-world biometric information on the user may be collected using a bio sensor, and the collected information may be controlled based on the sensor characteristics of the bio sensor, thereby enabling interaction between the real world and the virtual world, as well as between virtual worlds. In addition, an interactive game which is executed in the virtual world on the basis of the collected biometric information may be controlled to thereby produce a virtual world having enhanced realism. Moreover, the real-world health status of a user may be determined and displayed on the basis of the collected biometric information, thereby enabling the health status of the user to be seen.
摘要:
A virtual world processing apparatus and method. Information on sensor capability is converted to binary data and then transmitted, or converted to eXtensible Markup Language (XML) data, or the XML data is further converted to binary data and then transmitted. Accordingly, data transmission rate may be increased and a low bandwidth may be used. In a data-receiving adaptation real world to virtual world (RV) engine, complexity of the adaptation RV engine may be reduced by omitting an XML parser.

An apparatus and method for processing a virtual world. The apparatus for controlling a facial expression of an avatar in a virtual world using a facial expression of a user in a real world may include a receiving unit to receive sensed information that is sensed by an intelligent camera, the sensed information relating to a facial expression basis of the user, and a processing unit to generate facial expression data of the user for controlling the facial expression of the avatar, using initialization information representing a parameter for initializing the facial expression basis of the user, a 2-dimensional/3-dimensional (2D/3D) model defining a coding method for a face object of the avatar, and the sensed information.
摘要:
Disclosed are a virtual world processing device and method. By way of example, data collected from the real world is converted to binary form data which is then transmitted, or is converted to XML data, or the converted XML data is further converted to binary form data which is then transmitted, thereby allowing the data transmission rate to be increased and a low bandwidth to be used, and, in the case of a data-receiving adaptation RV engine, the complexity of the adaptation RV engine can be reduced as there is no need to include an XML parser.

A method and apparatus of correcting geometric information and providing a panoramic view. In the method of providing a panoramic view, a tilting vector (X′, Y′) is generated by applying matrices H(a,b) and HF to a source image vector (X,Y). The matrix H(a,b) is defined by distortion angles “b” towards a plane direction and a distortion angle “a” towards a depth direction of the source image, and the matrix HF is defined according to a camera parameter matrix K. Also, a two-dimensional vector (x,y) of a source image is converted into a three-dimensional vector (X,Y,W) on a retinal image plane having a unit radial distance from an origin of a ground plane. Also, a warped image width (WIW) is estimated from a width and a field of view (FOV) of the source image. A warping vector (x′,y′) is generated based on the converted vector (X,Y,W) and the WIW.
