Abstract:
The present invention relates to an apparatus and a method for storing brain activity data using image and distance information, which are capable of automatically correct noises that are generated when a subject moves in a bio-signal detection system. To this end, the apparatus for storing brain activity data using image and distance information is configured to comprise: a brain activity measuring sensor for measuring brain activity; an image measuring unit for measuring image and distance information; a movement detecting unit for detecting movement of the subject using the image and distance information measured by the image measuring unit; and a brain activity data storing unit for storing brain activity data measured by the brain activity measuring sensor, wherein the brain activity data storing unit stores the brain activity data excluding a part of the brain activity data in a range where the movement of the subject is detected by the movement detecting unit. [Reference numerals] (AA) Subject;(BB) Measure image and distance information;(CC) Measure brain waves;(DD) sense a movement;(EE) Trigger generated;(FF) Store the trigger;(GG) Store the brain waves;(HH) Eliminate noises
Abstract:
The present invention relates to an apparatus and a method for correcting the position of an MEG sensor and the position of the head of a person under test by using image and distance information and, more in detail, to an apparatus for enhancing the accuracy of measured MEG data by correcting automatically the position of the sensor and the head of the person under test in the case that the MEG sensor attached to the head of the person under test moves because the person moves. For this, the apparatus for correcting the position of an MEG sensor and the position of the head of a person under test by using image and distance information comprises: the MEG sensor for measuring activities of the brain; an initial position storing part for prestoring the position of the head of the person under test relative the position of the MEG sensor at an initial stage of sensing in the MEG sensor; an image measuring part for measuring the image and distance information; a position correcting part for detecting a movement of the person under test by using the image and the distance information measured from the image measuring part and correcting the position of the MEG sensor based on the position of the head relative to the position of the MEG sensor; and an MEG data storing part for storing MEG data measured from the MEG sensor.
