Abstract: 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.

Abstract: 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.

Abstract: Provided herein is a method for generating a road surface. The method for generating a road surface includes: obtaining a view height of a laser scanner used in an operation process through a mobile mapping system (MMS); determining a reference height on the basis of the obtained view height and a height measured by a global positioning system (GPS); extracting point cloud data positioned in a predetermined height range from the determined reference height among point cloud data obtained in the mobile mapping system; and generating the road surface on the basis of the extracted point cloud data.

Abstract: Disclosed herein is a method for measuring a position. The method for measuring a position includes: determining a GPS satellite visible area and a GPS satellite invisible area depending on whether or not an area is an area in which a predetermined number or more of GPS satellites are observable; measuring a position of a moving object on the basis of a first position measuring scheme using GPS satellites in the case in which the moving object enters the GPS satellite visible area; and measuring the position of the moving object on the basis of at least one of the first position measuring scheme and a second position measuring scheme other than the first position measuring scheme in the case in which the moving object enters the GPS satellite invisible area.
