Abstract: Provided are a method and system for noncontact vision-based 3D cognitive fatigue measuring. The method comprises: acquiring pupil images of a subject exposed to visual stimuli; extracting a task evoked pupillary response (TEPR) by using the pupil images; detecting dominant peaks from the TEPR; calculating latency of dominant peaks; and determining cognitive fatigue of the subject by comparing a value of the latency to a predetermined reference value.

Abstract: A space registration system includes a display apparatus, an image sensor, a processor, and a plane mirror. The display apparatus has an inherent display coordinate system which defines a coordinate of the virtual space. The image sensor has an inherent sensor coordinate system which defines a coordinate of the real space. The processor analogizes a transformation equation of the sensor coordinate system and the display coordinate system by means of symmetry of an incidence angle and a reflection angle of light with respect to the mirror surface, compares a coordinate of the reflection image with respect to the display coordinate system with a known coordinate of the reflection image with respect to the sensor coordinate system, and adjusts the transformation equation of the sensor coordinate system and the display coordinate system.
