Abstract
The present technology relates to an information processing device and an information processing method, capable of inhibiting corresponding-point detection accuracy from degrading. The information processing device according to the present technology, allows a projecting unit to project a second pattern including a first pattern including repetition in first cycles in a first direction, inverted in phase in second cycles in a second direction orthogonal to the first direction, in order to acquire corresponding relationship in pixel between the projecting unit and a capturing unit. The present technology can be applied to an electronic instrument including the function of a projector or the functions of both a projector and a camera, and a computer that controls the functions.
Claims19
An information processing device, comprising:
- a projecting device;
- a capturing device;
- and
- circuitry configured to:
- control the projecting device to project an image that includes a first pattern, wherein
- the first pattern is inverted in phase in first cycles in a first direction,
- the first pattern includes a second pattern repeated in second cycles in a second direction, and
- the second direction is orthogonal to the first direction;
- control the capturing device to capture the projected image that includes the first pattern;
- and
- acquire, based on the captured image, a relationship between a pixel of the projecting device and a pixel of the capturing device.
