Abstract:
The present disclosure relates to an image processing apparatus and a method capable of performing on-line sensing without synchronizing and without using a specialized device. An image corner corresponding point detection unit detects an image corner of an input image from a captured image captured by a camera, and associates four image corner points of a corrected image to be projected by a projector with four image corner points of the detected captured image, thereby detecting four image corner corresponding points. An attitude estimation unit estimates a relative attitude of the projector and the camera from the four image corner corresponding points. The present disclosure can be applied to, for example, a projection imaging device that projects an image with a projector, captures the image projected by the projector, and updates a presentation position.

Claim (Index 1):
An image processing apparatus, comprising:\n a correction unit that generates a corrected image by correcting an input image on the basis of attitude estimation information indicating an attitude estimation result of a projector; an image corner correspondence detection unit that detects image corner corresponding points by associating an image corner point of a captured image with an image corner point of the corrected image, the captured image being generated in such a manner that the corrected image corrected by the correction unit is projected by the projector and a projection image is captured; and an attitude estimation unit that generates the attitude estimation information by estimating an attitude of the projector on the basis of the image corner corresponding points detected by the image corner correspondence detection unit.
