Abstract: A method and apparatus for calibrating a camera are provided. The method and apparatus include obtaining a driving image captured by a camera mounted on a vehicle, segmenting line regions including straight lines from the captured driving image, extracting feature points of the straight lines from the line regions, projecting the feature points of the straight lines into a world coordinate system, and estimating an error for a calibration parameter of the camera including at least one of a pitch, a roll, or a yaw so that the feature points projected into the world coordinate system satisfy a line parallel condition.

Abstract: Disclosed is a method of detecting a traffic light with an object recognition model configured to recognize traffic lights. The method includes: obtaining an input image from a camera included in a vehicle, the input image among frames, including previous frames, captured by the camera; estimating, based on prior information about traffic light objects, a first region of interest (RoI) for the input image; determining a second RoI based on the first RoI and based on detection results of the previous frames, wherein the detection of results correspond to recognition results of recognizing traffic lights in the previous frames by the object recognition model; and recognizing, by the object recognition model, a traffic light in the input image, wherein the recognizing is based on the input image and the second RoI.
