Title:
PROJECTION SYSTEM AND METHOD FOR ADJUSTING PROJECTION SCREEN
Document Type and Number:
WIPO Patent Application WO/2021/174989
Kind Code:
A1
Abstract:
A projection system, comprising a projection screen (100), two or more than two screen frames (200), and a projector (300). Each screen frame (200) comprises a support member (210), a sliding block (230), and a drive controller (250). The sliding block (230) is fixedly connected onto the projection screen (100), and is movably connected to the support member (210). The drive controller (250) drives the sliding block (230) to move to generate a tractive force on the projection screen (100). The projector (300) is used for acquiring, by means of a camera (330), a projection image (303) formed when a screen adjustment feature pattern (301) is projected to the projection screen (100), generating adjustment parameters of the two or more than two screen frames (200) according to the reference value comparison of the projection image (303) and the screen adjustment feature pattern (301), and sending same to the drive controller (250), so that the drive controller (250) is driven to determine, according to the adjustment parameters, whether the fixing and installation of the projection screen (100) are smooth, and according to the adjustment parameters, the sliding block (230) moves to generate a tractive force on the projection screen (100), and thus the projection screen (100) is fixed and installed on the wall surface smoothly, achieving the optimal projection effect and facilitating improving the user viewing experience. Also provided is a method for adjusting the projection screen (100).
