ABSTRACT:
A mobile body surrounding surveillance apparatus comprises an image capturing section for capturing an image of a surrounding of a mobile body, a setting section for setting a landscape, band-like particular region parallel to a frame image with respect to image data captured by the image capturing section, an extraction section for taking image data of the particular region every one or more frame images captured in time series by the image capturing section, and extracting movement vector information based on the image data of the particular region, and a detection section for detecting another mobile body present in the surrounding of the mobile body based on the movement vector information.
