摘要：Although automobile is an indispensable vehicle to modern life, it also
serves as a social problem with a big traffic accident. Among the reasons of
traffic accidents, careless driving accounts for the largest part. So in order
to avoid the careless driving, a system which can measure the posture of a
driver and warns driver to drive carefully in the case of looking aside is
necessary. Although the image measurement method is used broadly, there is a
problem on which measurement accuracy is influenced by environment light,
makeup of the driver, etc. in the general method based on the two-dimensional
image. Therefore, in this study, we propose an image measurement method to
obtain the head posture of driver. First we use three-dimensional measurement
method which based on the infrared pattern projection to get 3-D information of
head, and then we calculate the angle for faces. In this paper, we explain the
composition method of an experiment system, and the results of head posture measurement
experiment.
