Image processing apparatus and image processing method

摘要

An index extraction unit detects indices from a sensed image sensed by a sensing unit which senses an image of a physical space on which a plurality of indices is laid out. A convergence arithmetic unit calculates position and orientation information of the sensing unit based on the detected indices. A CG rendering unit generates a virtual space image based on the position and orientation information. A sensed image clipping unit extracts, as a display image, an image in a display target region from the sensed image. An image composition unit generates a composite image by compositing the extracted display image and the generated virtual space image. A display unit displays the composite image.

1. An image processing apparatus comprising:
a sensing unit configured to sense an image of a physical space on which a plurality of indices is laid out; a detection unit configured to detect the indices from the sensed image; an acquisition unit configured to acquire a motion amount in the sensed image; an extraction unit configured to extract an extraction area, whose size is smaller than that of the sensed image, from the sensed image based on a displayable range of a display unit; a display area acquisition unit configured to acquire, as a display area, an area obtained by moving the extraction area in the sensed image based on the motion amount; a weighting unit configured to weight the detected indices based on the display area and locations of the detected indices; a calculation unit configured to calculate position and orientation information of said sensing unit based on the indices weighted by said weighting unit; a generation unit configured to generate a virtual space image based on the position and orientation information calculated by said calculation unit; a composition unit configured to generate a composite image by compositing a display image within the display area and the virtual space image generated by said generation unit; and a display unit configured to display the composite image generated by said composition unit.
