COMMUNICATION SYSTEM AND COMMUNICATION METHOD

Title:

COMMUNICATION SYSTEM AND COMMUNICATION METHOD

Document Type and Number:

Japanese Patent JP2009077394

Kind Code:

A

Abstract:

To communicate a representation of an event to one or more client devices via a communication network from a server, and to view one or more objects in a video image.

A communication system comprises an image processing apparatus and a distribution server. The image processing apparatus receives video images and processes them so as to extract one or more image features from each object, and generates object path data which provides the positions of identified objects over time. Furthermore, the image processing apparatus calculates a projection matrix to project the position of each object based on the object path data into a three-dimensional model. The distribution server receives the object path data and the projection matrix generated by the image processing apparatus, and distributes them to one or more client devices.
