چکیده

In this paper, we present an extensive study about the influence and the behavior of the intrinsic camera calibration imprecisions and their propagation into the extrinsic calibration between a camera and a multi-layer lidar. Usually, the extrinsic calibration process involves the pose estimation of a reference object in the Cartesian frame of each sensor. From this fact, it is necessary to know the camera intrinsic parameters for estimating the position of an object on an image. Therefore, the extrinsic calibration process is directly dependent of the intrinsic camera parameters. By using different projective camera models, we estimate the influence with respect to the computation of the extrinsic parameters.

Indirect Correspondence-Based Robust Extrinsic Calibration of LiDAR and Camera

LiDAR and cameras have been broadly utilized in computer vision and autonomous vehicle applications. However, in order to convert data between the local coordinate systems, we must estimate the rigid body transformation between the sensors. In this paper, we propose a robust extrinsic calibration algorithm that can be implemented easily and has small calibration error. The extrinsic calibration...

Automatic Extrinsic Calibration of Vision and Lidar by Maximizing Mutual Information

This paper reports on an algorithm for automatic, targetless, extrinsic calibration of a lidar and optical camera system based upon the maximization of mutual information between the sensor measured surface intensities. The proposed method is completely data driven and does not require any fiducial calibration targets—making in situ calibration easy. We calculate the Cramér-Rao lower bound (CRL...

Cross-Calibration of RGB and Thermal cameras with a LIDAR

In this paper we present a method for combining data from an RGB camera, a long-wave-infrared (LWIR) thermal camera, and a LIDAR to obtain a registered RGB-depththermal (RGBDT) point cloud. Our method assumes that the intrinsic parameters of the cameras are known. For geometric calibration of the thermal camera, we discuss the calibration target used. For cross-calibration, our method requires ...
