Title: METHOD AND DEVICE FOR DETERMINING FIXATION POINT MAPPING FUNCTION AND METHOD AND DEVICE FOR DETERMINING FIXATION POINT
Abstract:
A method and device for determining a fixation point mapping function, and a method and device for determining a fixation point. The function determining method comprises: combining all parameters to be solved in a fixation point mapping function to obtain a mapping vector of the fixation point mapping function, and determining a preferred solving parameter and a secondary solving parameter which correspond to the mapping vector (S102); carrying out solving on a preferred solving parameter of a first user according to an eye image of the first user and corresponding fixation point information thereof (S104); determining the solution of a secondary solving parameter of the first user according to a mapping vector obtained by performing solving on a plurality of second users (S106); and determining a fixation point mapping function of the first user according to the solution of the preferred solving parameter of the first user and the solution of the secondary solving parameter of the first user. The method is able to solve the problems of large user workload and disbenefit to user experience in which a fixation point mapping function is determined by utilizing a plurality of calibration points.
