Abstract
A projection system and an image processing method thereof are provided. The system includes a projector module, a photography module and a processing module. The projector module projects a first image frame to an object surface. The photography module photographs the object surface to derive a second image frame including the first image frame and an indication point, wherein the indication point is formed by light projected on the object surface by an external device. The processing module analyzes the second image frame to derive coordinate of the indication point in the second image frame, derives coordinate of at least a feature point of the first image frame in the second image frame according to a linear-approximation method, and transforms the coordinates of the indication point in the second image frame to the coordinates in the first image frame by using two-dimensional coordinate transformation equations.
