CalibrationGrid

The CalibrationGrids are fundamental tools for verifying the accuracy of the rc_visard and for implementing hand-eye calibration in robotic applications.

  • Available in two sizes (small/large)
  • Hand-eye calibration and/or camera calibration

Beschreibung

When an application requires knowledge of the spatial transformation from sensor frame to external frame, the necessary hand-eye calibration can be performed using a CalibrationGrid together with the rc_visard’s on-board software modules. A (re)calibration may also be needed if the rc_visard is exposed to strong mechanical impact (e.g. dropped).

The CalibrationGrid (small) is suitable for checking camera calibration and performing camera recalibration of the rc_visard 65. It can also be used for hand-eye calibration of all rc_visards; its compact size making the handling very convenient. Please note that this grid is not suitable for camera calibration of the rc_visard 160.

The CalibrationGrid (large) is suitable for checking camera calibration and performing camera recalibration of all rc_visards. It can also be used for hand-eye calibration of all rc_visards; but please note that its size may make the handling a bit difficult in conjunction with small robot systems.

Please note that while the calibration grids are printed on a sturdy substrate (6 mm alu-dibond); the painted surface is delicate and must be handled with care.
