Abstract:
Disclosed are a device and a method for recovering three-dimensional information which calculate a normalized cross correlation value using brightness information included in two or more stereo images, calculate a normalized edge correlation value using local edge information, and extract disparity surface information from a composite disparity image generated based on two types of matching costs.
Abstract:
Disclosed are a method and a device for matching a signal by measuring average exchange similarity. The present invention is proposed to efficiently find a peak with the highest similarity in two or more pieces of inputted signal information. The present invention determines a matching peak showing maximum similarity matching by calculating a plurality of matching factors with a similarity measuring unit based on average exchange and collecting the calculation results.

PURPOSE: An apparatus for an emergency vehicle stop is provided to stop a vehicle by spreading an emergency vehicle stop map in a cell area in wireless to stop a specific vehicle. CONSTITUTION: In an apparatus for an emergency vehicle stop, an ID management unit(102) assigns ID according to a connection request by using vehicle ID. The ID management unit generates an ID map by mapping ID information to the ID of the vehicle. An emergency vehicle stop map generation unit(104) generates an emergency vehicle stop map according to ID information and external emergency stop command. A map changing unit(106) updates the emergency vehicle stop map. A communications unit wirelessly spreads the vehicles emergency stop map.

CONSTITUTION: The vehicle control system(400) includes; a communications manager(402) taking charge of data communications with the region server device; a local path generating unit(404) created the local path according to the sensing information and a driving control command received according to the autonomic driving service request from the region server device; a route control part of slaved tracking(406) controlling the vehicles actuator for the vehicles to follow the local path; and a vehicle drive unit(408) performing the autonomic driving of the vehicles according to vehicles actuator. The driving control command includes; a full path from source to the destination location; an additional information including the vehicle speed and near-side lane; and an avoidance route corresponding to the generation of obstacle or event.
Abstract:
PURPOSE: A method of providing event situation guiding service to a user terminal is provided to interpret a message which is exchanged with a local server according to sequence message in an application program of a nomadic device. CONSTITUTION: A local server registers a user terminal in a client list if the user terminal is an effective terminal(408,410). The local server transmits meta data to the user terminal(414). The user terminal exchanges the local server, a request frame and a data frame(416). The local server checks generation of an event(418). The local server transmits an event situation guide message to the user terminal(420).

Abstract:
A method and an apparatus for producing the imaginary difference line are provided, which can produce the exact imaginary difference line by selecting the lane pattern. The road lane recognition part(20) analyzes the front road image of camera and recognizes lane. The attitude information of camera is produced from the information about the acknowledged lane. The lane pattern generation part(30) is supplied with the road linear information including linear toward the lane of the front road in the current position of vehicle to the basis from the electronic map information and produces the lane pattern. The imaginary difference line generating unit(40) selects the optimal lane pattern among a plurality of lane patterns. The imaginary difference line generating unit produces the imaginary difference line by using the selected lane information of the selected lane pattern.
Abstract:
An apparatus and a method for estimating the location of vehicles using the pixel size and the location of facilities as images are provided to enhance user convenience by compensating for GPS(Global Positioning System) signals through map matching with lanes. Images of current position is photographed through a video camera mounted on vehicles and traffic facilities are identified based on the photographed images of current position(201). Types of traffic facilities are identified by comparing the identified facilities with stored facilities, and the pixel size and the location of the facilities are extracted(202). The distance between the facilities and vehicles are identified by comparing the distances on pixel sizes of extracted facilities with stored facilities(203). Lanes are corrected according to the comparison of lane information and the location of the extracted facilities(204). The position of the vehicles is predicted based on the distance information, the lane information, and traveling information of the vehicles(205).
