Abstract
A projection system including a projection device, an image capturing device and a processing device is provided. The projection device projects a plurality of grid patterns to a projection target. The projection target includes a border region and a projection region. The border region surrounds the projection region. The grid patterns are deformed at the border region. The image capturing device captures a capturing image including an image of the projection target. The image of the projection target includes a deformation region. The processing device receives the capturing image including the image of the projection target, and determines a position of the border region according to the deformation region of the image of the projection target, and controls the projection device to project a projection image to the projection region of the projection target according to the position of the border region.
