Abstract:
The present invention relates to a radar device, and a device, a method and a system for detecting an object using image mapping. According to the present invention, the device for detecting an object comprises: a radar sensor unit to receive radio signals reflected by one or more objects using an antenna; an image processing unit to generate an image on certain space including one or more objects; and a calculating unit to detect one or more objects from the reflected radio signals by giving an intrinsic identifier (ID) to each of one or more objects, wherein the calculating unit generates detection information on one or more objects by mapping one or more objects detected from the reflected radio signals with the image based on the intrinsic ID.

Abstract:
PURPOSE: A road monitoring method using radar and an apparatus thereof are provided to inform accurate road conditions of drivers by monitoring the state of the road through radar. CONSTITUTION: Reflected wave of a radar signal is collected by a road information collecting apparatus(S510). A radar signal is projected on the surface of the road by the road information collecting apparatus. The surface state of the road is determined by using a dielectric constant(S520). The dielectric constant information is included in the reflected wave. An obstacle on the road is detected trough the reflected wave. The risk levels of the road are determined(S540).

PURPOSE: A method for storing and managing an extendable mark-up language document and a medium storing a software being programmed for performing the method are provided to store and search a XML document as a database form through an interface by linking to all existing database schemata by performing a mapping between the used database schema structure and a DTD document defining a XML document structure. CONSTITUTION: A network connecting unit of a XML repository program for a user terminal controls a network adapter of a user terminal and connects to a server through an information communication network(S210). If the user selects a menu for storing a XML document previously prepared on a user interface screen in a database, a browser controls a display of a user interface screen and reads a XML document wanted by a user(S220), and judges whether the user selects a XML document(S230). A XML processing unit analyzes a DTD of a XML document to be transmitted from a user terminal and a DTD managing unit judges whether the DTD of the XML document is the DTD being stored in a DTD repository of the server(S240). If the user selects a predetermined node in a tree structure of a DTD using a keyboard or a mouse, a browser displays contents of DTD of a node of a DTD tree selected by a user on a user interface screen(S250). The browser displays DMD list transmitted from a server on a user interface screen(S260) and controls the display for making the user select each DMD item(S270). The browser checks whether the user selects a displayed item(S280), and outputs a transmission request of DMD contents information selected by the user. The network connecting unit of a XML repository program transmits DMD contents information to an interface unit(S290). The browser controls the display for selecting a storage of a XML document(S300). The XML processing unit reads and maps DMD contents information and stores the information in the database(S310).
