IPC: A61B5/16
Filed: 2006-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To early detect sleepiness and lack of vigilance by imaging a face image using a camera etc., detecting sight line from the face image, analyzing detailed motion of the sight line, and determining vigilance.  <P>SOLUTION: In a means to detect the sight line by measuring the face image using the camera etc., a middle point of eyeballs is presumed through acquisition of feature points, basic reference points, etc. of the face from the face images, trace of feature points of the face in consideration of direction or rotation of the face, and detection of blink, etc. The sight line can be presumed by calculating the amount of displacement of iris of the eye by computing a projected point on an image surface from the middle point of presumed eyeballs. When gazing at front, usually minute motion of the sight line is active, its coverage is large and information can be acquired correctly. Meanwhile, when sleepiness arises or vigilance declines, minute motion of the sight line becomes inactive and its coverage is narrow, and information cannot be acquired correctly. Therefore, if the coverage of the minute motion of the sight line is analyzed, sleepiness and lack of vigilance can be determined and early detected.  <P>COPYRIGHT: (C)2008,JPO&INPIT
