You will need the mounting values R, X and Angle of the individual sensor.
x = MachineX - X
y = MachineY - R

// rotation matrix from machine coordinates (centre of die holder) to sensor coordinates
SensorX = cos(Angle) * x + sin(Angle) * y
SensorY = -sin(Angle) * x + cos(Angle) * y

 

Example Values (rectangle ROI):

 

P = Machine Coordinate Points
S = Sensor Coordinate Points

See chapter 11.5 for calculation.
