Abstract
A method for triggering projection fusion calibration and a projection system is provided, including the following. First and second display contents are projected respectively onto a projection surface by a first projection device and a second projection device and fused into a complete display content including an overlapping area and a first non-overlapping area corresponding to a part of the first display content. A first image on the projection surface is captured, a first sharpness value corresponding to the first non-overlapping area and a specific sharpness value corresponding to the overlapping area based on the first image are obtained, and a first sharpness value difference between the first sharpness value and the specific sharpness value is obtained. In response to determining the first sharpness value difference being greater than a first threshold a fusion calibration operation is triggered, or a fusion calibration prompt is provided.
