Calibration of two real-life projectors - possible?

Is it possible to calibrate two (real-life) projectors with unity?
The calibration should fulfill following requirements:

  • Both projectors project the parts of a full image onto a square floor.
  • There is overlapping of the projections on the floor.
  • The resulting superposed image is supposed to look like the full image.
  • The edges of the projections should match the edges of the square floor

There’s nothing built into Unity to do what you want. Projector calibration is really its own field usually with dedicated software to do all of the structured light work necessary to calibrate and align the projectors.
