A vehicle controller includes a communications unit for performing data communications with local servers; a local path generation unit for generating, in response to an automatic vehicle guidance service request, a local path based on a driving control command and sensing information received from the local servers via the communications unit; a path-following control unit for generating actuator control signals for controlling actuators of a vehicle to drive the vehicle along the local path; and a vehicle driving unit for driving the actuators according to the actuator control signals. Each local server pre-processes and merges sensor data received from the infra-sensor to generate the sensing information. A global server generates the driving control command based on the sensing information and transmits the driving control command to the local servers.

Automatic vehicle guidance system

A system for remotely controlling a vehicle in a service area divided into plural service sectors includes: an infra sensor module installed in each service sector for periodically sensing obstacles and vehicles within the service sector; a vehicle controller mounted in each vehicle for requesting the driving guidance service and automatically controlling the vehicle in accordance with a vehicle control signal; and a local server installed in each service sector for communicating with the vehicle controllers through a driving guidance network based on information on the obstacles and vehicles sensed by the infra sensor module. The system further includes a global server for allocating network resources of the driving guidance network to allow the local server to communicate with the vehicle controllers using the allocated network resources.

Provided are a method and apparatus for estimating a center line of an intersection by recognizing a crosswalk on a road input through a camera installed in a vehicle. The apparatus includes a road information providing unit which provides information about a road being traveled based on location information of a traveling vehicle; a crosswalk recognizing unit which recognizes a crosswalk based on an input image of the intersection and the information about the road and obtains a distance from the traveling vehicle to the crosswalk; and an intersection center line estimating unit which estimates the center line of the intersection based on the information about the road and the distance from the traveling vehicle to the crosswalk. Since the center line of the intersection is estimated, the apparatus and method of estimating a center line of an intersection according to the present invention can prevent traffic accidents occurring frequently at an intersection and helps indicate direction information of 'real vehicle navigation.'

Disclosed is a method for providing services on online geometric correction using, in which information related with GCP (Ground Control Point) used for correcting geometric distortion of an image collected by an aircraft or a satellite are transmitted online through Internet network, thereby allowing a user at a remote place to perform geometric correction or ortho-rectification. In the geometric correction process, the image information related with the GCP is provided but the precise geographic coordinate of the GCP itself is not provided to thereby maintain the secretion of detailed geographic information.
