Document Type and Number:
WIPO Patent Application WO/2023/112558
Kind Code:
A1
Abstract:
A video adjustment system of this disclosure comprises: a video projection device that projects a projection video to a projection target; an imaging device that acquires a first image which captures a first region that includes a portion of the projection video, and a second image which captures a second region that includes a different portion of the projection video and that includes an overlapping region in which the first region and the second region overlap; and a control unit that controls the projection position of the projection video. The control unit: converts a first coordinate system of the first image and a second coordinate system of the second image into a composite coordinate system shared in common by the first image and the second image; generates correction information which includes position information indicating a projection range of the video projection device, in the composite coordinate system; and generates a projection video on the basis of the correction information.
