US 2021/0343044 A1 · VEHICLE CAMERA CALIBRATION APPARATUS AND METHOD

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.
