Mobile body surrounding surveillance apparatus, mobile body surrounding surveillance method, control program and computer-readable recording medium
First Claim
1. A mobile body surrounding surveillance apparatus comprising:
- an image capturing section for capturing an image in a surrounding of an own mobile body;
a particular region setting section for setting a particular region for image data captured by the image capturing section, the particular region being parallel to the horizontal direction of a frame image and rectangular having a long edge in the horizontal direction;
an own mobile body movement direction detection section for detecting a movement direction of the own mobile body and outputting a movement direction information indicating the detected movement direction;
a movement vector information extraction section for taking the image data of the particular region for each of one or a plurality of frame images captured by the image capturing section in time series and adjusting a detection sensitivity based on the movement direction information so as to extract a movement vector information on another mobile body; and
a change detection section for detecting a moving state of the other mobile body which is present in the surrounding of the own mobile body based on the movement vector information.

18. A mobile body surrounding surveillance method comprising:
-
an image capturing step of capturing an image data in a surrounding of an own mobile body as a frame image, the image data being captured by an image capturing section in time series; a setting step of setting a particular region which is parallel to the horizontal direction of the frame image and rectangular having a long edge in the horizontal direction for each of one or a plurality of captured frame images; an own mobile body movement direction detection step of detecting a movement direction of the own mobile body and outputting a movement direction information indicating the detected movement direction; a movement vector information extraction step of taking the image data of the particular region for each of one or the plurality of the captured frame images and extracting a movement vector information on another mobile body based on the image data of the particular region and the movement direction information; and a change detection step of detecting a moving state of the other mobile body which is present in the surrounding of the own mobile body based on the movement vector information. - View Dependent Claims (19, 20, 21, 22)
