First Claim
1. A spatial image information system for efficient storage and retrieval of spatial images acquired by an image acquisition device provided with a navigation system, the system comprising:
- a spatial image query interface component section for performing an interface function for interfacing with an external client, and processing a spatial image database construction query, spatial image retrieval/insertion/deletion queries, and a spatial object information manipulation query in the spatial images;
a spatial image meta information component section for managing schema and index information of spatial image sequences, and processing a query about index information if the query about the index information is inputted from the spatial image query interface component section;
a spatial image storage/retrieval component section for processing storage, retrieval and management of the spatial image sequences according to the query of the spatial image query interface component section;
a spatial image to real coordinate conversion component section for receiving and converting the spatial image and a specified position in the image into a real-world coordinate (x,y,z) or receiving and converting the real-world coordinate (x,y,z) and the spatial image into the specified position in the spatial image according to the query of the spatial image query interface component section; and
an open type spatial image database interface component section for storing and managing the spatial images by interfacing the spatial image meta information component section, the spatial image storage/retrieval component section and the spatial image to real coordinate conversion component section with a storage system irrespective of a kind of the storage system.

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.

14. A method for retrieving spatial images including a designated area in a spatial image information system for storing the spatial images acquired by an image acquisition device provided with a navigation system using a database structure composed of spatial image sequence tables for storing the spatial images and information, spatial image object tables for storing information on spatial objects existing in spatial image sequences, a spatial image sequence information table including schema information and indexes of the spatial image sequences and summary information, and a spatial image sequence index table for managing indexes so as to promptly retrieve the spatial image sequence tables, the method comprising:
-
a spatial image sequence filtering step of retrieving the spatial image sequences including the designated area using the spatial image sequence indexes of the spatial image sequence index table;
a spatial image filtering step of retrieving the spatial images including the designated area with respect to the spatial image sequences retrieved at the spatial image sequence filtering step; and
a spatial image refining step of checking whether a real spatial image includes the designated area by loading the spatial images, which are retrieved at the spatial image filtering step, from the spatial image sequence tables. - View Dependent Claims (15)
