A method for controlling autonomous lane change of a vehicle is disclosed. The method comprising: receiving a destination from a user; determining a current position of the vehicle; calculating a driving route from the current position to the destination; when an intersection exists within in a predetermined distance on the driving route while performing the route guidance according to the calculated driving route, confirming a ranking of a search link positioned on the calculated driving route among search links exiting from an end node corresponding to the intersection; comparing rotation direction information of the search link corresponding to the confirmed ranking of the search link with moving direction information of a lane of a lane link corresponding to the lane on which the vehicle is currently positioned; and performing lane change guidance of the vehicle according to a comparison result of the rotation direction information and the moving direction information.

Apparatus, method, computer program, and computer readable recording medium for route guidance

A method for controlling autonomous lane change of a moving body is disclosed. The method includes calculating a driving route from a current location of the moving body to a destination; determining whether an intersection or a forked road exists at a predetermined distance from the current location of the moving body on the calculated driving route; checking, when the intersection or the forked road exists, link information corresponding to a lane in which the moving body is located, and determining a moving direction toward the intersection or the forked road; determining an entry route for entering the intersection or the forked road according to the determined moving direction; and generating a control signal for controlling a moving direction of the moving body according to the determined entry route.

Device, method, computer program, and computer readable-recording medium for route guidance

Disclosed is an image processing method. The method includes the steps of receiving an image obtained from a plurality of vehicles positioned on a road, storing the received images according to acquisition information of the received images; determining a reference image and a target image based on images having the same acquisition information among the stored images, performing an image registration using a plurality of feature points extracted from each of the determined reference image and target image, performing a transparency process for each of the reference image and the target image performed with the image registration, extracting static objects from the transparency-processed image, and comparing the extracted static objects with objects on an electronic map pre-stored to updating the electronic map data, when the objects on the electronic map data pre-stored are different from the extracted static objects.

Image processing apparatus, image processing method, computer program and computer readable recording medium

Provided is an image processing method. The image processing method includes receiving images acquired from a plurality of vehicles positioned on a road; storing the received images according to acquisition information of the received images; determining a reference image and a target image based on images having the same acquisition information among the stored images; performing an image registration using a plurality of feature points extracted from each of the determined reference image and target image; performing a transparency process for each of the reference image and the target image which are image-registered; extracting static objects from the transparency-processed image; and comparing the extracted static objects with objects on map data which is previously stored and updating the map data when the objects on the map data which is previously stored and the extracted static objects are different from each other.

Disclosed herein are an apparatus and a method for route guidance.
