Abstract:
A moving object data system having an index managing function for improving access speed to moving object data and a method for managing the index are provided to dynamically support insertion/search/deletion of a moving object by using the present index. A query processing component(200) inserts location information of the moving object by a location report of the moving object or processes a search/deletion request for the stored location information of the moving object. A data managing component(300) stores/manages the location information of the inserted moving object. An index managing component(400) includes more than one index component(500) differently applied to each moving object, and manages each index component according to the insertion/search/deletion request for the location information of the moving object. A disk managing component(600) stores the location information and the index information of the moving object. A screen outputting component(100) outputs location of the moving object or the information included by the searched object to a screen.
Abstract:
PURPOSE: A location obtaining system of a moving object for minimizing a communication load is provided to reduce a frequency of obtaining future moving object location information by using past location information of a moving object in an LBS(Location Based Service), thereby minimizing a communication load. CONSTITUTION: A moving object location obtaining time checker(202) stores moving objects in a standby queue to maintain a standby state, checks time of each moving object by going round a loop, and removes a moving object whose obtaining time elapses from the standby queue. A location obtaining framework portion(204) receives information on the removed moving object to store the information in the standby queue, and assigns the information to an empty thread within a thread pool for obtaining location information of the multiple moving objects. A location obtaining device portion(206) accesses to various location obtaining sources, and obtains substantial location information. A location obtaining model portion(208) resets location obtaining time of the obtained moving object, and calculates the time by applying various location obtaining processes.
Abstract:
PURPOSE: A position information management system of numerous moving objects is provided to manage a position store room by dividing it in a store unit having a specific store period to perform management and search of the large capacity position information effectively. CONSTITUTION: A position acquisition sub system(100) acquires the present position of a moving object by a specific position acquisition strategy. A position store sub system(200) temporarily stores the position information reported from the position acquisition sub system in a memory buffer(210) where a memory slot is allocated per each moving object, and divides the memory slot in a store unit having a specific store period and then stores it in the position room permanently when all of the position information of a corresponding moving object is stored. A position inquiry sub system(300) searches position information of the moving object stored in the position store sub system by performing a position inquiry as to the position information of a specific moving object.
Abstract:
PURPOSE: A device for synthesizing images using multi satellite images is provided to use saturation when synthesizing more than two satellite images to make new images, thereby maintaining maximum information and implementing high-density image synthesis. CONSTITUTION: A receiver(210) receives images of a Landsat TM satellite. A band selector/combiner(220) selects bands of the received satellite image, and combines the bands. An HIS(Hue Intensity Saturation) converter(230) performs an HIS conversion with band units combined by the band selector/combiner. A 3S component extractor(240) extracts 3S components of an HIS-converted image of the HIS converter. An image synthesizer(250) synthesizes the extracted 3S components with an image of a high-resolution satellite.
