WEARABLE APPARATUS FOR SIGHT LINE FOCUS POSITIONING AND METHOD FOR SIGHT LINE FOCUS POSITIONING

摘要

A wearable apparatus for sight line focus positioning and a method for sight line focus positioning. The apparatus comprises: a glasses stand (1), wherein left and right eyeglass frames of the glasses stand (1) are respectively mounted with a plurality of infrared light sources (2), the plurality of infrared light sources (2) are distributed at different positions on the left and right eyeglass frames for illuminating irises from different angles, and the left and right eyeglass frames are further respectively mounted with a camera (3) used for shooting an iris image illuminated by the infrared light sources; the glasses stand (1) is further mounted with a signal processing unit (4), wherein the signal processing unit (4) comprises: a synchronization control module used for controlling turn-on of the plurality of infrared light sources respectively according to a set order, and while the infrared light sources are turned on, synchronously triggering the cameras (3) on the eyeglass frames where the infrared light sources are turned on to shoot the iris image illuminated by the infrared light sources, and an image processing module used for processing the iris image to establish a 3D model of the left-eye and right-eye irises; and a left-eye and right-eye sight line focus is positioned according to the 3D model of the left-eye and right-eye irises. Sight line focus positioning of high precision can be realized.
