New chessboard pattern

New chessboard pattern had been applied. The pattern is 8*5 in size, and each block is 26 mm.

The two sets (RGB and IR) of pictures used for calibration are shown as following:
Once images were taken, I applied them separately in GML calibration tool. It gives intrinsic matrices, extrinsic matrices, and distortion parameters.

The extrinsic matrices for RGB camera is:
42.92  73.12  316.15  -2.00  2.06  0.42
63.21  -48.93  319.51  -0.02  3.03  0.24
57.10  -36.59  366.05  -0.06  2.51  -0.29
39.41  -72.19  361.86  0.63  2.60  -0.16
-31.39  -55.33  219.10  -1.73  -2.10  -0.78
42.52  15.09  495.30  0.25  3.07  -0.03
47.00  -92.77  482.56  1.44  2.23  -0.59
The intrinsic matrices for RGB camera is:
524.10  0  312.14
0  524.91  249.84

The extrinsic matrices for IR camera is :

58.14  75.58  330.03  -1.99  2.04  0.40

80.93  -46.85  333.38  -0.03  3.00  0.26

57.72  -92.78  502.68  1.45  2.19  -0.57

The intrinsic matrices for RGB camera is:

612.32  0  326.70

0  614.54  242.53

Further calculation of mapping RGB to IR camera will be applied.
