Automatic Targetless Extrinsic Calibration of a 3D Lidar and Camera by Maximizing Mutual Information
11 years 10 months ago
This paper reports on a mutual information (MI) based algorithm for automatic extrinsic calibration of a 3D laser scanner and optical camera system. By using MI as the registratio...
