Abstract
A projection control method includes causing a projector to project a projection image including projection indexes, causing a camera to capture the projection image, causing a display to display an instruction for a user to position camera indexes within an imaging range, the camera indexes indicating positions relative to the projection indexes in a camera coordinate system obtained by capturing the projection image, detecting camera coordinates which are the coordinates of the camera indexes positioned, and determining, according to relative positional relations between the projection indexes and the camera indexes, the correspondence relations between the camera coordinates and projection coordinates.
Claims16
A projection control method performed by a processor to control projection of an image by a projector, the projection control method comprising:
- causing a camera to capture a plurality of projection indexes positioned within a projection range of the projector within an imaging range in order to generate a projection index image;
- causing a display to display an instruction for a user to position a plurality of camera indexes within the imaging range, the plurality of camera indexes indicating positions relative to the plurality of projection indexes in a camera coordinate system obtained by capturing the projection index image;
- detecting camera coordinates which are coordinates of the plurality of camera indexes positioned;
- and
- generating , according to relative positional relations between the plurality of projection indexes and the plurality of camera indexes, a set information indicating correspondence relations between the camera coordinates and projection coordinates in a projection coordinate system of a projection image projected by the projector.
A projection control device that controls projection of an image by a projector, the projection control device comprising:
- a detection controller that causes a camera to capture a plurality of projection indexes positioned within a projection range of the projector within an imaging range in order to generate a projection index image;
- a display controller that causes a display to display an instruction for a user to position a plurality of camera indexes within the imaging range, the plurality of camera indexes indicating positions relative to the plurality of projection indexes in a camera coordinate system obtained by capturing the projection index image;
- a camera coordinate detector that detects camera coordinates which are coordinates of the plurality of camera indexes positioned;
- and
- a controller that generates, according to relative positional relations between the plurality of projection indexes and the plurality of camera indexes, a set information indicating correspondence relations between the camera coordinates and projection coordinates in a projection coordinate system of a projection image projected by the projector.
