Abstract:
The present invention relates to an advertisement providing system and a method thereof. The advertisement providing system of the present invention receives first contents registration information and second contents registration information for providing an advertisement from an advertisement provider, stores the received information, the first contents registration information including basic advertisement contents and the second contents registration information including additional advertisement contents that corresponds to the basic advertisement contents, and provides a stored web page and the basic advertisement contents to a user terminal. When receiving a user action on the basic advertisement contents for activating the additional advertisement contents from the user terminal, the advertisement providing system provides the additional advertisement contents to the user terminal. According to the present invention, an advertisement is provided by re-selling existing advertisement contents instead of providing a location-based basic advertisement, thereby increasing advertising efficiency with minimum expenses.

Abstract:
Disclosed is a spatial image information method and system for rapid and efficient storage in a relation type database and retrieval and management of spatial images acquired by a combined system of a global positioning system (GPS), an inertial navigation system (INS), and an image acquisition device (i.e., CCD camera). The spatial image acquired by the GPS/INS/CCD camera combined system is combined with an exterior orientation composed of a camera position (x,y,z), accelerated velocity, slope and direction at the moment the image is acquired and an interior orientation acquired by a camera calibration, so that calculation of a specified spatial coordinate information becomes possible. The spatial image information system includes a section for efficiently storing a chain of still spatial image sequences acquired by the GPS/INS/CCD camera combined system, the exterior orientation, and the interior orientation in the relation type database, a section for storing spatial information recognized as the same object by a user as maintaining the relationship with the stored still spatial image sequences, a section for efficiently retrieving images that satisfy a certain spatial information operation from the still spatial image sequences, and an interface section for external systems.
