Abstract

The invention discloses a human eye tracking method and a human eye tracking device. The human eye tracking method comprises performing face detection on a current face image when a user views a target screen to obtain a current face model; according to the current face model, determining a current position of the centers of pupils of both eyes; obtaining sight parameters of both eyes according toa calibrated face image when the user views a calibration point on the target screen; calculating a current position of a sight fixation point of both eyes according to the sight parameters of both eyes and the current position of the centers of the pupils of both eyes; and performing fusion on the current position of the sight fixation point of both eyes to obtain the current position of a sightdroppoint on the target screen. According to the tracking method, a specified infrared camera does not need to be used, and an infrared light source also does not need to be arranged additionally. Therefore, complex hardware architecture is not required, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a human eye tracking method and a human eye tracking device. Background technique [0002] Eye tracking technology is a technology that recognizes the operation of the human eyeball, analyzes the changes in the gaze of the human eye, and then realizes the related operations of using the human eye to control the device according to the change in the gaze. This technology can be applied to virtual reality and human-computer interaction. and other fields. [0003] The existing eye tracking technology needs to use multiple invisible infrared light sources to supplement the light of the human eye, and then use the infrared camera to obtain the eye image when the human eye moves, and then to construct the operating condition of the human eye in space. Modeling and analysis calculates the line of sight changes of human gaze. [0004] The above-mentioned eye tracking technolo...
