Patent ID: 7376247

Claim:
A target detection system comprising: a radar for scanning an interior of a specified area by radiating a radio wave, for outputting target data responsive to a target being detected in the specified area based on receipt of a reflected wave, for outputting a flag in a first state in response to the target being detected in a first distance range, for outputting the flag in a second state in response to the target being detected in a second distance range, and for outputting no flag in response to the target being detected in a third distance range; an image acquisition unit for acquiring an image of the specified area and outputting corresponding image data; an image recognition unit for outputting edge data by processing the image data output from said image acquisition unit; and a processing unit for selecting the edge data associated with a distance in the first distance range in response to the flag being output in the first state, for selecting the edge data associated with a distance in the second distance range in response to the flag being output in the second state, and for selecting the edge data associated with a distance in the third distance range in response to no flag being output, and for detecting the target based on the selected edge data and the target data output from said radar.
