Abstract
An object detection processing sectiondetects an object region, using at least one of multiple viewpoint images (e.g., left-viewpoint image) with different viewpoint positions on the basis of information learned through prior learning. A distance measuring sectionperforms ellipse fitting on the object region detected by the object detection processing sectionto set a distance measurement point arrangement region, and sets multiple distance measurement points in the distance measurement point arrangement region. The distance measuring sectionperforms a stereo matching process using the multiple viewpoint images to calculate a parallax with sub-pixel accuracy for each of the distance measurement points corresponding to the object indicated by an image of the object region and, on the basis of the calculated parallaxes, generates distance measurement information regarding the object. Thus, the distance measurement information regarding the object can be generated without elongating a baseline distance between imaging sections that acquire the multiple viewpoint images with different viewpoint positions to such an extent that the object can be distinguished from the background.
