How is the calibration formula derived?
According to the tri stimulus method, color sensors are calibrated with the following formula:
K=(XYZ*XsYsZs T)*( XsYsZs * XsYsZs T)
variables are:
K : 3x3 correction matrix
XYZ: 3x4 target data
XsYsZs : 3x4 sensor data
T: transponse of matrix-1: Inverse of matrix
