A high-precision eye movement tracking system based on a novel magnetoresistance effect quantum sensing

Abstract

The application discloses a high-precision eye movement tracking system based on a novel magnetoresistance effect quantum sensing, and relates to the technical field of eye movement tracking. The high-precision eye movement tracking system based on the novel magnetoresistance effect quantum sensing comprises the following modules: a collection and preprocessing module, which is used for preprocessing observation data and configuration data; an array observation differentiation discrimination module, which is used for array screening and risk marking according to array observation differentiation analysis results; a mapping reversible discrimination module, which is used for pose interval screening and working interval constraint processing; a constraint eye movement solving module, which is used for pose decision and pose solving; and a dynamic compensation and trajectory output module, which is used for correction, trajectory output and archiving. The high-precision eye movement tracking system solves the problems that, in the prior art, the phenomenon of local folding of a magnetic field-pose mapping relationship or overlapping of observation responses is prone to occurring in part of an eye rotation interval, different eye poses correspond to similar magnetic field measurement results, and thus multiple solutions exist in pose solving or the stability of the pose solving is insufficient.
