A projection system includes a projection device including a projector unit and a camera unit, a signal transmitter unit mounted to a projection screen, and a processing unit. The camera unit captures an image of a projection image projected by the projector unit onto the projection screen, and the processing unit obtains a position of the projection image accordingly. The processing unit obtains a position of the projection screen based on signals wirelessly transmitted by the signal transmitter unit and adjusts setting parameter(s) related to the projector unit based on a comparison between the positions of the projection image and the projection screen to reduce dimensional and/or positional differences between the two.
