  • 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.
