Abstract: A vehicle camera calibration apparatus and method are provided. The vehicle camera calibration apparatus includes a camera module configured to acquire an image representing a road from a plurality of cameras installed in a vehicle, an input/output module configured to receive, as an input, the acquired image from the camera module, or output a corrected image, a lane detection module configured to detect a lane and extract a feature point of the lane from an image received from the input/output module, and a camera correction module configured to estimate a new external parameter using a lane equation and a lane width based on initial camera information and external parameter information in the image received from the input/output module, and to correct the image.

Abstract: A camera calibration method includes obtaining a plurality of images of surroundings of a vehicle captured by a plurality of cameras, setting a region of interest (ROI) in each of the images, detecting one or more feature points of the set ROIs, matching a first feature point of a first ROI and a second feature point of a second ROI based on the detected feature points, calculating a first bird-view coordinate of the first feature point and a second bird-view coordinate of the second feature point, and calibrating the cameras by adjusting an extrinsic parameter of each of the cameras based on an error between the first bird-view coordinate and the second bird-view coordinate.
