Abstract: Provided are a method and apparatus for determining the location of a pedestrian, and the method includes obtaining, from a camera, a plurality of images of an outside of a vehicle and obtaining, from a radar, a plurality of radar measurement values of the outside of the vehicle, determining a pedestrian object included in the plurality of images, setting a plurality of object size candidate values for the pedestrian object, and determining longitudinal location candidate values for the plurality of object size candidate values, respectively, selecting radar measurement values located within a preset distance from the plurality of longitudinal location candidate values, and determining a final longitudinal location value of the pedestrian object, based on the selected radar measurement values.

Abstract: Provided are a method and device for annotating a detected object. The method of annotating a detected object may include classifying a class of the object, generating a bounding box including a first quadrangle and a second quadrangle both sharing one side, for the object based on the class of the object, and generating an annotation on the object in units of the bounding box.

Abstract: A method of generating an improved training data video includes recognizing an object included in a first image by applying at least two recognition techniques to the first image acquired during driving, applying at least two detection techniques to a result of recognizing the object and detecting a frame by each of the applied detection techniques, generating a frame set including a plurality of frames by integrating the detected frames, and generating a second image by sampling the integrated frame set.

Abstract: Provided is a method of improving an object recognition rate including recognizing a first object in a first image obtained while driving, detecting whether the recognized first object has disappeared for a preset time period and then reappeared in the first image, based on detecting that the first object has reappeared, calculating training data for the first object, and controlling such that a recognition model for recognizing an object included in an image is to be trained based on information based on the calculated training data.
