Abstract
An image processing unit of the disclosure includes an imaging section that acquires a plurality of partial images as a captured image, by imaging a projection screen provided by a projector through division of the projection screen into a plurality of regions to have partially overlapping imaging regions, and an estimation section that performs an operation a plurality of times on a basis of the captured image, the operation being performed to estimate a projection transformation matrix for linking of the partial images adjacent to each other.
Claims10
An image processing unit, comprising:
- circuitry configured to:
- image a projection screen, wherein the projection screen is provided by a projector;
- acquire a plurality of partial images as a captured image based on a division of the projection screen into a plurality of regions, wherein the plurality of regions has partially overlapped imaging regions;
- and
- perform first estimation of a projection transformation matrix based on the captured image, wherein
- the first estimation of a projection transformation matrix is performed in a case where a first image pattern composed of the plurality of partial images is projected by the projector as the projection screen, and
- each partial image of the plurality of partial images has an image feature point with a unique local feature amount.
An image processing method, comprising:
- imaging a projection screen, wherein the projection screen is provided by a projector;
- acquiring a plurality of partial images as a captured image based on a division of the projection screen into a plurality of regions, wherein the plurality of regions has partially overlapping imaging regions;
- and
- performing first estimation of a projection transformation matrix based on the captured image, wherein
- the first estimation of the projection transformation matrix is performed in a case where a first image pattern composed of the plurality of partial images is projected by the projector as the projection screen, and
- each partial image of the plurality of partial images has an image feature point with a unique local feature amount.
A projection system, comprising:
- a projector configured to project a projection screen;
- and
- circuitry configured to:
- image the projection screen;
- acquire a plurality of partial images as a captured image based on a division of the projection screen into a plurality of regions, wherein the plurality of regions has partially overlapped imaging regions;
- and
- perform first estimation of a projection transformation matrix based on the captured image, wherein
- the first estimation of the projection transformation matrix is performed in a case where a first image pattern composed of the plurality of partial images is projected by the projector as the projection screen, and
- each partial image of the plurality of partial images has an image feature point with a unique local feature amount.
