An example system for projector image alignment. The system for projector image alignment can include a processor to compare a first calibration-pattern image projected by a first projector and at least a portion of a second calibration-pattern image projected by a second projector and generate a geometric model of an aligned image for display by both the first projector and the second projector. The processor can also send a first projector portion of the aligned image to the first projector based on the geometric model of the aligned image.
