The disclosure provides a method for adjusting pixel values of blending image. The method includes projecting, on a projection surface, a first projection image onto a first projection range and a second projection image onto a second projection range by a first projector and a second projector, and blending the first projection image and the second projection image to generate a blending image; calculating positions of a plurality of boundaries of the first projection range and the second projection range; adjusting a range of an overlapping area between the first projection range and the second projection range; and adjusting image parameters of a non-overlapping area outside the overlapping area, to enable pixel values of the non-overlapping area to be close to pixel values of the overlapping area.

Method for adjusting pixel values of blending image and projection system thereof

A method and device for homogenizing images of projectors is provided, and includes: projecting a first test pattern on respective projection images of projectors, projection images between a first and a second projectors among the projectors having an overlapping area, and the first test pattern having grid lines; selecting, in the grid lines of the first test pattern on the projection image of the first projector, an inner and an outer boundaries of the overlapping area of the first projector; selecting, in the grid lines of the first test pattern on the projection image of the second projector, an inner and an outer boundaries of the overlapping area of the second projector; gradually reducing a brightness from the inner to the outer boundaries of the overlapping area of the first projector; gradually reducing a brightness from the inner to the outer boundaries of the overlapping area of the second projector.

Method and device for homogenizing images of multiple projectors

A projection system and a projection method thereof are provided. The projection system includes a projection device, a memory, an image capturing device, and a processor. The memory records a corresponding relationship between a plurality of test patterns and a plurality of sets of image capturing parameters. The projection device projects the plurality of test patterns toward a projected area. The processor controls, according to the corresponding relationship recorded in the memory, the image capturing device to shoot the projected area with the plurality of sets of image capturing parameters to obtain a plurality of first reference images corresponding to the plurality of test patterns, and controls, according to the plurality of test patterns and the corresponding plurality of first reference images, the projection device to project a projection image.
