Abstract
A determination apparatus and method for gaze angle are provided. The apparatus analyzes an image to generate a plurality of facial triaxial positioning values and a plurality of facial landmark points. The apparatus obtains a plurality of specific facial landmark points from the facial landmark points to generate a heatmap, and compares the heatmap with a standard heatmap to generate an image compensation value. The apparatus performs a facial correcting process based on the image and the image compensation value to generate a virtual corrected image. The apparatus analyzes the virtual corrected image to obtain a displacement of pupil. The apparatus determines a gaze angle of a user according to a determination model for gaze angle, the facial triaxial positioning values and the displacement of pupil.
