TARGET RECOGNITION SYSTEM AND TARGET RECOGNITION METHOD EXECUTED BY THE TARGET RECOGNITION SYSTEM
First Claim
1. A target recognition system to recognize one or more recognition targets, operatively connected to a stereo imaging device to capture a stereo image of an area ahead ofthe target recognition system,the target recognition system comprising:
- a parallax calculator to calculate parallax of the stereo image including two captured images acquired by the stereo imaging device;
a target candidate detector to detect a candidate set of recognition target areas, based on a luminance image of one of the captured images; and
a target recognition processor to limit the candidate set of recognition target areas detected by the target candidate detector within a range of threshold values of characteristics in the candidate set of recognition target areas set in advance based on the parallax calculated by the parallax calculator to extract and output the one or more recognition targets.

Abstract
A target recognition system operatively connected to a stereo imaging device to capture a stereo image of an area ahead of the target recognition system, includes a parallax calculator to calculate parallax of the stereo image including two captured images; a target candidate detector to detect a candidate set of recognition target areas based on a luminance image of one of the captured images; and a target recognition processor to limit the candidate set of recognition target areas detected by the target candidate detector within a range of threshold values of characteristics in the candidate set of recognition target areas set in advance based on the parallax calculated by the parallax calculator to extract and output the one or more recognition targets.

3. A target recognition method executed by a target recognition system to recognize one or more recognition targets, operatively connected to a stereo imaging device to capture a stereo image of an area ahead of the target recognition system,
the method comprising the steps of: -
calculating parallax of the stereo image including two captured images acquired by the stereo imaging device; detecting a candidate set of recognition target areas, based on a luminance image of one of the captured images; limiting the candidate set of recognition target areas within a range of threshold values of characteristics in the candidate set of recognition target areas set in advance based on the parallax; and extracting and outputting the one or more recognition targets.
