Image processing apparatus
First Claim
1. An image processing apparatus that processes comprising:
- a stereo camera including a reference camera to capture a reference image and a comparison camera to capture a comparison image;
an image processing controller configured toobtain disparity information of each point commonly found in the reference image andthe comparison image for calculating three-dimensional distance information to be used to specify an obiect captured by the stereo camera;
a recognition processing controller configured to;
specify a target object area encircling the object in one of the reference image andthe comparison image based on the three-dimensional distance information,the object including a plurality of objects located within a predetermined distance;
perform spatial filter processing of the target object area to extractan image feature amount including at least one of a brightness mode value which is cumulative frequencies of edge strength of the object in the target area, andan average value of the edge strength of the object in the target area; and
determine whether or not the object in the target object area is a smoky object, based on the image feature amount in the target object area.

Abstract
An image processing apparatus which employs a basic configuration including an image processing controller which processes images captured by a stereo camera and a recognition processing controller which recognizes an object based on information from the image processing controller includes a target object area specifying unit, feature amount extracting unit and smoke determining unit as functions of enabling recognition of a smoky object. The target object specifying unit specifies an area of an object which is a detection target, by canceling the influence of the background, the feature amount extracting unit extracts an image feature amount for recognizing a smoky object in a target object area and the smoke deciding unit decides whether the object in the target object area is a smoky object or an object other than the smoky object, based on the extracted image feature amount.
