Abstract: A method for adjusting a projection parameter and a projection system are disclosed. In the projection system, a processor is configured to drive multiple projectors to project multiple projection images respectively and obtain a full projection range through calculation, select a target area from at least one overlapping area included in the full projection range and obtain a target projection parameter value of the target area, obtain multiple intersection points of the overlapping area on a boundary of the full projection range, define connecting lines between a center point of the target area and the intersection points as dividing lines to divide the full projection range into multiple sub-areas, respectively adjust a projection parameter value of each of the sub-areas according to the target projection parameter value of the target area, and perform projection through the corresponding projector based on the adjusted projection parameter value of each of the sub-areas.

Abstract: A method for adjusting a projection boundary and a projection system are provided. Multiple imaging apparatuses corresponding to multiple projection apparatuses are driven, and each imaging apparatus obtains a corresponding captured image by capturing projected image projected by corresponding one projection apparatus and surrounding area of the projected image. All captured images are displayed on a display, and a main bounding box corresponding to each projected image and a reference bounding box corresponding to the surrounding area are displayed on each captured image. The main bounding box of each captured image is independently adjusted relative to the reference bounding box to obtain an adjusted main bounding box. A full image boundary is calculated based on the respective adjusted main bounding boxes. The projection apparatuses are driven to project an adjusted full image based on the full image boundary.

Abstract: A projection system and a projection image adjustment method thereof are provided. The projection image adjustment method is applicable to a processing device connected to multiple projectors, a display, and an input device, and includes the following steps. Arrangement information between the multiple projectors is obtained. Multiple adjustable areas corresponding to a projection image of each projector are simultaneously displayed on the display and the multiple adjustable areas are simultaneously displayed on projection images of the multiple projectors according to the arrangement information. A parameter setting interface corresponding to a first adjustable area among the multiple adjustable areas is displayed on the display. The first adjustable area corresponds to a first projector among the multiple projectors.

Abstract: 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.
