The present invention relates to the field of robot visual sense technology. The digital video eye motion analyzer consists of video input unit, image collecting card, microprocessor and display. Eye motion locus recognition in robot visual sense technology includes the steps of: image collection of serial eye motions, digital image processing and analysis, and storing and displaying. The analyzer has the advantages of non-contact non-destructive detection, digitalizing, adjustable sampling period and capability of real-time tracking pupil motion and displaying eye motion locus. The present invention may be used widely in the psychological and behavioral analysis of people and animal in various fields as well as in medical diagnosis.
Description
Technical field:
The present invention relates to a kind of digital video eye motion analyzer, belong to the machine vision technique field.
Background technology:
The technology that adopts machine vision technique to discern identity according to the physiology and the behavior characteristics of human body self has caused the extensive concern of international academic community and business circles.People's physiological feature mainly comprise fingerprint, face picture, iris, etc., people's behavior characteristics mainly comprises person's handwriting, sound etc.Adopt the research that people's eye pupil and iris image are discerned to be primarily aimed at people's authentication [1] at present.And discern human or animal's the rarely found report of mental activity according to human or animal's physiological feature (pupil and iris).Cited paper [1]:
