Integrated Radar-Camera Sensors: The Next Generation of Sensor Fusion William A. Bauson Delphi Electronics and Safety Jan. 27, 2010 Active Safety Sensor Functions Detect objects - “There’s something out there” Determine salient features of the object y Location – “It’s in front of me” y Range – “It’s really close” y Range rate – “It’s coming closer” y Size – “It’s really big” y Classification – “It’s a semi truck” Assess threat level – “This looks bad” Initiate appropriate countermeasures – “Hit the brakes!” 2 Commonly Used Sensors Cameras (visible, thermal) yBest suited to detecting and identifying objects RADAR – RAdio Detection And Ranging or LIDAR – LIght Detection And Ranging yBest suited to detecting and measuring range to objects 3 Radar Camera Comparison Characteristic Radar Camera + - Target range + - + - Range rate + - + - Detecting objects in inclement + - weather Sensor Fusion + - Long range operation + - combines the - + strengths of both Target angle - + sensing technologies - + Angular rate - + - + Size or angular extent (edges) - +
