Abstract
There is provided an image processing apparatus and a method that allow for corresponding point detection at a higher speed and with higher accuracy. By outputting invisible light and visible light via the same optical system, an image of the invisible light and an image of the visible light are projected to cause a portion or all of the image of the invisible light and a portion or all of the image of the visible light to be projected in the same region on a projection surface. The present disclosure is applicable to, for example, an image processing apparatus, an image projecting apparatus, an image projection imaging apparatus, a control apparatus, an information processing apparatus, a projection imaging system, an image processing method, a program, or the like.
Claims20
An image processing apparatus comprising:
- a projector configured to
- output invisible light and visible light via a same optical system, and
- project an image of the invisible light and an image of the visible light to cause a portion or all of the image of the invisible light and a portion or all of the image of the visible light to be projected in a same region on a projection surface,
- wherein the projector projects the image of the invisible light based on prior calibration information, and
- wherein the image processing apparatus further comprises circuitry configured to perform correction on a pattern image on a basis of the prior calibration information, the pattern image including a predetermined feature point and a predetermined variable pattern, the pattern image being directed to detection of corresponding points of a projected image projected by the projector and a captured image captured by a camera, the correction correcting a captured image of the projected image to cause the feature point and the variable pattern to be positioned at a predetermined pixel, the captured image of the projected image being captured by the camera.
An image processing method comprising:
- outputting, by an image processing apparatus, invisible light and visible light via a same optical system;
- and
- projecting an image of the invisible light and an image of the visible light to cause the image of the invisible light and the image of the visible light to be superimposed on each other,
- wherein the image of the invisible light is projected based on prior calibration information, and
- wherein the image processing method further comprises performing correction on a pattern image on a basis of the prior calibration information, the pattern image including a predetermined feature point and a predetermined variable pattern, the pattern image being directed to detection of corresponding points of a projected image projected by the projector and a captured image captured by a camera, the correction correcting a captured image of the projected image to cause the feature point and the variable pattern to be positioned at a predetermined pixel, the captured image of the projected image being captured by the camera.
