Abstract

The embodiment of the invention discloses an eyeball tracking processing method and a related device, which are applied to electronic equipment, and the method comprise the following steps: when eyeball tracking calibration is carried out by using a first calibration point, obtaining a first face image through an eyeball tracking assembly; calculating a reference user sight vector and a head posture vector according to the first face image; converting the reference user sight vector into a standard user sight vector according to the head posture vector and the first calibration point; and obtaining a first parameter group according to the standard user sight vector and the coordinate of the first calibration point, adding a training set to the first parameter group, and training a calibration model through the training set to obtain a trained calibration model. According to the method of the invention, the method facilitates the improvement of the processing efficiency during the calibration of eyeball tracking.

Description

Technical field [0001] This application relates to the technical field of mobile terminals, and in particular to an eye tracking processing method and related devices. Background technique [0002] With the widespread application of smart phones and other mobile terminals, smart phones can support more and more applications and more powerful functions. Smart phones are developing in a diversified and personalized direction and become an indispensable electronic product in users’ lives. . For smartphones with eye-tracking function, when performing eye-tracking calibration points, due to factors such as ambient light, changes in head posture, and slight jitter of the phone’s posture will affect the smartphone’s judgment of the user’s eye gaze point, so eye-tracking calibration The efficiency and accuracy of the process are low. Summary of the invention [0003] The embodiments of the present application provide an eye tracking processing method and related devices, which are benef...
