IMAGE PROCESSING DEVICE AND METHOD

The present disclosure relates to an image processing device and method capable of suppressing a reduction in the accuracy of corresponding point detection. A homography transformation is applied to a captured pattern image obtained as a result of an imaging unit capturing an image of a predetermined structured light pattern projected by a projection unit, and using the captured pattern image with the homography transformation applied to detect corresponding points between the projected image projected by the projection unit and the captured image captured by the imaging unit. The present disclosure can be applied to, for example, an image processing device, an image projection device, a control device, an information processing device, a projection imaging system, an image processing method, a program, and the like.
