Abstract:
A projection system and a projection method are provided. The projection system includes a first projector and a second projector. The first projector is configured to project a first grid picture onto a projection surface. The second projector is configured to project a second grid picture onto the projection surface. The second grid picture and the first grid picture are blended into a blended projection picture. The first grid picture includes a first overlap region. Grid lines of the first overlap region are displayed in a first color. The second grid picture includes a second overlap region. Grid lines of the second overlap region are displayed in a second color. The first color and the second color are complementary colors. When the blended projection picture is formed, grid lines of an overlap region of the first grid picture and the second grid picture are displayed in a recognition color.
