Moving object detection apparatus and moving object detection method
First Claim
1. A moving object detection apparatus that analyzes a photographic image captured by an onboard camera and detects a moving object in the photographic image, comprising:
- an imaging portion that captures the photographic image at a predetermined time interval;
a storage portion that stores a first template representing a figure characteristic of a first moving object having a size smaller than a predetermined size, and stores a second template representing a figure characteristic of a second moving object having a size larger than the predetermined size,a peripheral region detection portion that compares the photographic image with the first template or the second template, and detects the first moving object and the second moving object as the moving object in a peripheral region provided on each of right and left sides in the photographic image; and
a central region detection portion that detects the first moving object as the moving object in a central region provided at a center of the photographic image,wherein;
the central region detection portion detects the first moving object and the second moving object as the moving object when the second moving object has been detected in the peripheral region of the photographic image obtained at a previous time.

Abstract
A moving object detection apparatus that analyzes a photographic image captured by an onboard camera and detects a moving object is provided. The moving object detection apparatus includes an imaging portion that captures the photographic image at a predetermined time interval; a peripheral region detection portion that detects a first moving object of a size smaller than a predetermined size and a second moving object of a size larger than the predetermined size as the moving object in a peripheral region; and a central region detection portion that detects the first moving object as the moving object in a central region. The central region detection portion detects the first moving object and the second moving object as the moving object when the second moving object has been detected in the peripheral region at a previous time.

11. A moving object detection method of analyzing a photographic image captured by an onboard camera and detecting a moving object in the photographic image, comprising:
-
capturing the photographic image at a predetermined time interval; setting a central region detection template for a central region and a peripheral region detection template for a peripheral region from a storage portion that stores a first template representing a figure characteristic of a first moving object having a size smaller than a predetermined size and stores a second template representing a figure characteristic of a second moving object having a size larger than the predetermined size; detecting the first moving object and the second moving object as the moving object through comparison with the first template or the second template, in the peripheral region provided on each of right and left sides of the photographic image; detecting the first moving object as the moving object through comparison with the first template, in a central region provided at a center of the photographic image; and storing detection results of the detecting the first moving object and the second moving object in the peripheral region and the detecting the first moving object in the central region, wherein; the detecting the first moving object in the central region detects, in addition to the first moving object, the second moving object as the moving object when the second moving object has been detected in the peripheral region of the photographic image obtained at a previous time.

12. A moving object detection apparatus that analyzes a photographic image captured by an onboard camera connected to an imaging portion capturing the photographic image at a predetermined time interval, and detects a moving object in the photographic image, comprising:
-
a storage portion that stores a first template representing a figure characteristic of a first moving object having a size smaller than a predetermined size, and stores a second template representing a figure characteristic of a second moving object having a size larger than the predetermined size, a peripheral region detection portion that compares the photographic image with the first template or the second template, and detects the first moving object and the second moving object in a peripheral region provided on each of right and left sides of the photographic image as the moving object; and a central region detection portion that detects the first moving object in a central region provided at a center of the photographic image as the moving object, wherein; the central region detection portion detects the first moving object and the second moving object as the moving object when the second moving object has been detected in the peripheral region of the photographic image obtained at a previous time. - View Dependent Claims (13)

14. A moving object detection apparatus that analyzes a photographic image captured by an onboard camera and detects a moving object in the photographic image, comprising:
-
an imaging portion that captures the photographic image at a predetermined time interval; a storage portion that stores a first template representing a first figure characteristic of a first moving object having a size smaller than a predetermined size, and stores a second template representing a second figure characteristic of a second moving object having a size larger than the predetermined size; a peripheral region detection portion that is configured to compare the photographic image with the first template and the second template, and detects the first moving object and the second moving object as the moving object in a peripheral region provided on each of right and left sides in the photographic image; and a central region detection portion that compares the first template with a central region provided at a center of the photographic image, wherein; the central region detection portion compares the central region with the first template and the second template in response to the second moving object being detected in the peripheral region of a preceding photographic image obtained at a previous time.
