Abstract:
An eyeball tracking module for video glasses, including: at least two infrared light sources, at least one image sensor assembly and at least one infrared cut-off filtering device. Each of the image sensor assembly comprises an image sensor body and an infrared filter provided in front of the image sensor body. The at least two infrared light sources are fixedly provided in an area laterally in front of an eyeball and are used for emitting infrared light to the eyeball, so as to form, on the eyeball which reflects the infrared light, a reflection point. The at least one image sensor assembly is fixedly provided at an edge or outside of a visual angle of video glasses. The at least one infrared cut-off filtering device is provided in an overlapping area between a reflection light path of the eyeball and an acquisition area of an image sensor.
