what is the signifincance and the use of "scaleFactor" and "translationToGlobalCoordinates" from the calibrations of each camera

There is a file named map.png whose resolution is 1920x1080. and it is pre-defined ground plane.
So, (coordinates + translationToGlobalCoordinates) * scaleFactor transforms your coordinates (or world coordinate x,y of specific camera) to the ground plane.

@visionNoob Your understanding is correct. Note that the origin is the bottom left of the map.png.
