Title:
超短焦点スクリーンの位置合わせ方法、装置、超短焦点投影機器及び媒体
Document Type and Number:
Japanese Patent JP7263546
Kind Code:
B2
Abstract:
This application provides an ultra-short-throw picture and screen alignment method which includes that: a first lateral projected image and a second lateral projected image are acquired by two cameras when an ultra-short-throw projector projects a picture; image processing is performed on the first lateral projected image and the second lateral projected image to obtain a projection position in a projection area and a screen position in a screen area; and the picture is adjusted according to the screen position and the projection position, so that a position of an adjusted projection picture and a target position coincide. In this application, the projected images are acquired by the two cameras, thereby ensuring acquisition of complete images; the projection position and the screen position are obtained by cooperative processing, the picture is adjusted according to the projection position and the screen position, so that accuracy in projection picture adjustment and display effects are improved. This application also provides an ultra-short-throw picture and screen alignment apparatus, an ultra-short-throw projection device, and a computer-readable storage medium all having the above advantages.
