1. A setting method, adapted to a projection system, wherein the projection system comprises a processing device and at least one projector, the projector comprises a projection unit and an image capturing unit, and the setting method comprises:
firstly, projecting an image frame onto a projection plane by the projection unit, wherein the image frame comprises a grid point array;
secondly, capturing the image frame on the projection plane by the image capturing unit according to different values of at least one setting parameter of the image capturing unit, so as to obtain a plurality of captured images corresponding to the different values of the at least one setting parameter; and
then, analyzing the captured images to determine whether the captured images meet a preset image condition,
when one of the captured images meets the preset image condition, selecting the one of the captured images,
setting the image capturing unit with a value of the at least one setting parameter corresponding to the selected captured image automatically, or
when all of the captured images fail to meet the preset image condition, projecting a prompt image onto the projection plane by the projection unit for reminding a user manually adjusting values of the at least one setting parameter of the image capturing unit of the projector.
