Abstract
In stereo matching based on standard area matching, in order to suppress a decrease in matching accuracy, it is effective to adaptively change a matching area in accordance with the local properties of an image. However, this requires high calculation costs. Thus, the present invention provides a stereo image processing apparatus including an image pickup unit 101 configured to take a plurality of image data using a plurality of cameras, an image memory 102 configured to store the plurality of image data taken by the image pickup unit 101, a calculated disparity storage unit 105 configured to store disparity data determined based on the plurality of image data, a matching area control unit 103 configured to set a matching area for each pixel based on the plurality of data read from the image memory 102 and the disparity data read from the calculated disparity storage unit 105, and a disparity calculating unit 104 configured to perform matching on the image data based on the plurality of image data read from the image memory 102 and the matching area for each pixel set by the matching area control unit 103 to calculate disparity data.
