  • Patent number: 12155928
    Abstract: A projection system and a method for selecting an image capturing number for image blending are provided. Multiple projection devices are driven one-by-one to project a pattern; multiple image capturing devices are driven to capture the pattern projected by each projection device, so as to obtain multiple image capturing results corresponding to the image capturing devices. Finally, at least one of the image capturing devices is selected to serve as an image capturing source for image blending based on the image capturing results. An image capturing range is identified through projected patterns, and an effective range is calculated and then selected for use, which is used for calculations required for automatic blending, so as to avoid a problem of being unable to maintain blending and merging due to environmental influences or failure of the image capturing device when performing image recognition and calculation required for automatic blending and merging.

  • Publication number: 20240106996
    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.
