Title:
PROJECTION SYSTEM AND IMAGE PROJECTION METHOD
Document Type and Number:
Japanese Patent JP2022145612
Kind Code:
A
Abstract:
To provide a projection system, where the projection system includes a projection target, a projection device, an image acquisition device, and a processor circuit.SOLUTION: A projection target includes a reflective surface and an anti-reflective film affixed on the reflective surface. The anti-reflective film defines a projection range. An image capturing device captures a first captured image containing the projection target. The first captured image includes an image of the anti-reflective film. A processor circuit determines a position and a shape in the anti-reflective film in the first captured image based on the first captured image. A projection device projects a projection image on the projection target. The projection device adjusts the projection image based on the position and the shape of the anti-reflective film, and correspondingly adjusts the projection image to the projection range. In addition, an image projection method is also provided. The projection system and the image projection method of the present invention can automatically adjust the projection image to correspond to the projection range.SELECTED DRAWING: Figure 1
