Title:
IMAGE PROJECTION SYSTEM, IMAGE PROJECTION DEVICE, AND IMAGE PROJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/110022
Kind Code:
A1
Abstract:
In this image projection system, an arithmetic device generates, on the basis of the positional relationship between a projection pattern image and a captured pattern image, conversion information used for performing conversion between camera coordinates used by an imaging device and projector coordinates used by an image projection device, and the imaging device captures an image of a photographic subject including a person, and the arithmetic device detects a first position that indicates a position concerning camera coordinates of a specific region of a person, and the arithmetic device converts, on the basis of the conversion information, first position information into second position information that indicates a position concerning projector coordinates of the specific region, and the image projection device projects, on the basis of the second position information, a warning image so as to overlap over the entire area of the specific region.
