AUTOMATIC CALIBRATION OF ODOMETRY AND ROBOT EXTRINSIC PARAMETERS USING MULTI-COMPOSITE-TARGETS FOR A DIFFERENTIAL-DRIVE ROBOT WITH A CAMERA

Automatic Calibration of Odometry and Robot Extrinsic Parameters Using Multi-Composite-Targets for a Differential-Drive Robot with a Camera

This paper simultaneously calibrates odometry parameters and the relative pose between a monocular camera and a robot automatically.Most camera pose estimation methods use natural features or artificial landmark tools.However, there are mismatches and scale ambiguity for natural features; the large-scale precision landmark tool is also challenging
