Abstract

Embodiments of the invention provide a fixation point calculation method, device and equipment. The method comprises the steps of determining a three-dimensional space model of a first scene; obtaining a first panoramic image shot in the first scene, wherein the first panoramic image comprises a face image of a face; determining a spatial position of the face according to the first panoramic image; according to the first panoramic image, determining a sight line direction of human eyes in the human face; and determining a fixation object of the human eye according to the three-dimensional space model, the space position and the sight line direction. According to the invention, the precision of tracking the sight of the human eyes in the three-dimensional space model is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a gaze point calculation method, device and equipment. Background technique [0002] With the rapid development of computer vision and human-computer interaction technology in recent years, human eye gaze tracking technology is of great significance for user behavior analysis and efficient human-computer interaction. For example, the user unlocks the mobile phone, computer and other operations by controlling the movement track of the line of sight. [0003] In the prior art, the human eye gaze tracking technology usually uses infrared light source and camera to locate the line of sight. For example, infrared rays are reflected from the surface of the eyeball to the camera, which will change the imaging of the eyeball, and the pupil of the human eye will turn white. Reflection points also turn white. However, this technology usually requires the use of multiple infra...
