APPLICATION OF HUMAN FACIAL FEATURE RECOGNITION TO AUTOMOBILE SAFETY

摘要

PPROBLEM TO BE SOLVED: To provide an imaging system whose determination precision has been improved when using face recognition software. PSOLUTION: The imaging system uses an infrared emitter 30 that emits an infrared signal along a predetermined field-of-view, and an infrared sensor 34 for receiving reflected infrared illumination from objects in the field-of-view. A processor including the face recognition software is used to detect human faces to identify and track a person. The infrared emitter is subjected to pulse operation for a prescribed number of frames in video data for a prescribed time interval, and is subjected to pulse stop for a prescribed time interval over the same number of frames in video data. The processor performs frame difference to obtain the difference in frames so that the background can be excluded. PCOPYRIGHT: (C)2007,JPO&INPIT
