Hand-eye calibration

Compute offset from tracker 1 to tracker 2 given sequences of matrices of every tracker. Depends on module and Math.Net Numerics.

See "Hand-eye calibration", Horaud et Dornaika, Intl. Journal of Robotics Research, Vol. 14, No 3, pp 195-210, 1995 for details.

Usage

Call the following static method:

static public bool HandEyeCalibration.Compute(List<Matrix4x4> a, List<Matrix4x4> b, out Matrix4x4 origin_offset, out Matrix4x4 tracker_offset)

with:

a: Sequence of tracker A matrices (For example a robot 'hand' coordinate system). Size has to be > 3

b: Sequence of tracker B matrices (For example a robot 'eye' coordinate system). Size has to be > 3

outpout parms:

origin_offset: Transformation from A origin to B origin, expressed in A

tracker_offset: Transformation from tracker A to tracker B, expressed in A

It is advised to feed the method with 10+ couples of matrices, depending on the quality of the measurements.

Tested on Win10, Unity 2019, Math.Net v4.5.
