Human being detection apparatus, method of detecting human being, and human being detecting program
First Claim
1. A human being detection apparatus for detecting a human being in a plurality of picture images including a moving object shot by a plurality of cameras, comprising:
- a moving object detecting part that detects a target region of the moving object in the picture images and a target distance to the moving object from the camera as moving object information on the basis of parallaxes in picture images and a difference between picture images sequentially entered;
a head region setting part that sets a head region as having a predetermined size corresponding to the target distance in the target region detected by the moving object detecting part when it is assumed that the moving object is the human being;
a sample image storing part for storing a sample image having a predetermined size corresponding to the head region of the human being; and
a human being determining part that determines whether the moving object is the human being by converting the head region, set by the head region setting part, in the picture image into an image having the predetermined size and comparing the converted head region with the sample image to determine that the moving object is the human being.

Abstract
A human being detection apparatus includes a moving object detecting part for detecting a target region from the picture image as a region of the moving object and a target distance as a distance to the moving object, a head region setting part for setting the head region corresponding to the target distance, a sample storing image part for storing a sample image having a predetermined size corresponding to the head region of the human being, and a human being determining part for determining whether or not the moving object is a human being by comparing the head region in the picture image converted to have a predetermined size with the sample image.

7. A method of detecting a human being included in a plurality of picture images including a moving object shot by a plurality of cameras, comprising the steps of:
-
detecting a target region of the moving object in the picture images and a target distance to the moving object from the camera as moving object information on the basis of parallaxes in picture images and a difference between picture images sequentially entered;
setting a head region as having a predetermined size corresponding to the target distance in the target region when it is assumed that the moving object is the human being;
generating a head edge image as an edge image corresponding to the head region;
converting the head edge image into a normalized image having the predetermined size;
generating a complemented image in which gaps in the normalized image converted by the size normalizing part are filled;
calculating a similarity between the complemented image and a sample image of the head region having the predetermined size previously stored in a sample image storage; and
determining that the moving object is the human being on the basis of the similarity.

8. A human being detecting program for causing a computer to operate, to detect a human being from a plurality of picture images shot by a plurality of cameras, to have functions of:
-
a moving object detecting part that detects a target region of the moving object in the picture images and a target distance to the moving object from the camera as moving object information on the basis of parallaxes in picture images and a difference between picture images sequentially entered;
a head region setting part that sets a head region as having a predetermined size corresponding to the target distance in the target region detected by the moving object detecting part when it is assumed that the moving object is the human being;
a sample image storing part for storing a sample image having a predetermined size corresponding to the head region of the human being; and
a human being determining part that determines whether the moving object is the human being by converting the head region set by the head region setting part in the picture image into an image having the predetermined size and comparing the converted head region with the sample image to determine the moving object is the human being.
