The invention discloses an eye movement monitoring method and an eye movement monitoring device; the method comprises the steps of collecting an image frame of puil; extracting a pupil pixel set (S) according to the predetermined threshold; extracting a boundary value of the pupil pixel set; setting a center point based on the boundary value and dividing the pupil pixel set into four quadrant sets (S1, S2, S3 and S4), wherein pixels of the first and third quadrant sets (S1 and S3) form a straight line, and the pixels of the second and fourth quadrant sets (S2 and S4) also form the straight line; calculating the coordinate of crosspoints of the two straight lines and traversing points in the four quadrants, wherein the crosspoints form a pupil center coordinate set (S5); and calculating an average value of horizontal and vertical directions according to the pupil center coordinate set (S5), wherein the average value is a center point position of the pupil. According to the eye movement monitoring method and the eye movement monitoring device, the eye movement image can be observed and recorded directly, and the eye movement state can be analyzed, recorded and displayed in a graphics mode timely. |
