Abstract

The invention provides a method for determining a fixation position and a related device, which are used for solving the problems of poor universality, tedious process and low efficiency of a fixation position determination mode in the related technology. According to the method, the left eye region, the right eye region and the face region are decomposed from the image shot by the camera, then the three regions are analyzed to obtain the comprehensive features, and the left eye feature expression and the right eye feature expression are obtained by analyzing the left eye region image and the right eye region image on the basis of the comprehensive features; and finally, combining the comprehensive features and the facial features to obtain a fixation position. In the whole process, only important features including the facial features, the comprehensive features, the left eye feature expression and the right eye feature expression need to be extracted, and then the watching positions of the human eyes can be classified based on the features. A user does not need to watch a fixed point, correction data are collected, and the accuracy of the fixation position can be ensured through feature description of multiple layers.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to a method and a related device for determining a gaze position. Background technique [0002] Eye sight usually contains a lot of information, which can reflect points of interest, concentration, and even psychological state. Automatic real-time estimation of eye sight is of great value to various researchers and daily production and life. However, in the past, it was usually necessary to purchase professional equipment to achieve a more accurate line of sight estimation. [0003] In the field of gaze estimation, many different technical routes have been proposed recently, which are mainly classified into three categories: the technical route based on eye model reconstruction to estimate the three-dimensional direction of sight; the technical route based on regression-based two-dimensional eye features to estimate the gaze point of the screen; technic...
