Abstract
A method for camera-Lidar calibration includes acquiring an image captured by a camera at a specific time point and a Lidar point cloud captured by a Lidar and projected onto a camera coordinate system at the specific time point, extracting a ground edge image corresponding to an edge of a ground surface, from the image extracting a road mark point cloud representing a road mark on the ground surface, from the Lidar point cloud, generating a first variation indicating a predicted position variation by predicting a position variation of the road mark point cloud to the ground edge image, through a neural network, and calibrating the camera and the Lidar, based on the first variation.
