odom_extrinsic_calibrate

Introduction

This C++ library supports the following tasks:

  1. Intrinsic calibration of differential-driven mobile robot odometer(radius_left, radius_right).
  2. Extrinsic self-calibration of sensor-odometer(3D, delta_x, delta_y, delta_theta).

The workings of the library are described in the this paper:

     Brookshire J, Teller S. Automatic calibration of multiple coplanar sensors[J]. Robotics: Science and Systems VII, 2012, 33.
