  • Publication number: 20210254989
    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.

  • Publication number: 20210224560
    Abstract: A method for measuring an inter-vehicle distance includes acquiring a driving image photographed by a photographing device of a first vehicle which is being driven; detecting a second vehicle from the acquired driving image; detecting first feature points of a second vehicle region in a first frame corresponding to a frame in which the second frame is detected before a frame in which the second vehicle is not detected among a plurality of frames constituting the driving image, when the second vehicle is not detected from the driving image; detecting second feature points in a second frame corresponding to a current frame by tracking the detected first feature points; calculating a feature point change value between the first feature points and the second feature points; and calculating an inter-vehicle distance from the photographing device of the first vehicle to the second vehicle based on the calculated feature point change value.

  • Publication number: 20210044425
    Abstract: An electronic device and an operating method thereof according to various example embodiments may be configured to acquire video data and audio data, to scramble audio data of a time interval (?T) in non-time order, and to store the video data and the scrambled audio data together. According to an example embodiment, the time interval (?T) may be fixed to be the same with respect to continuous audio data. According to another example embodiment, the time interval (?T) may vary using a function of receiving an input of a secret key and order and outputting a unique value, such as a Hash-based Message Authentication Codes (HMAC)-based One-time Password (HOTP) algorithm.

  • Publication number: 20190383630
    Abstract: Disclosed herein are an apparatus and a method for route guidance. The method for route guidance includes receiving a destination from a user; determining a current position of a 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 existing on 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 on which the vehicle is positioned; and performing lane change guidance of the vehicle according to a comparison result of the rotation direction information and the moving direction information.
