Description

Technical field

[0001] The invention relates to machine vision and automatic control technology, in particular to a device and method for recognizing gaze direction of human eyes and its application in intelligent control. The invention is a new technology for judging the gaze direction of human eyes based on video images. This technology does not require additional auxiliary equipment except for a single camera, a processor and an image interface. The recognition method is simple and fast, and can be used in machine vision and intelligence Many application fields of control make the machine's response to humans more active, friendly and accurate. Background technique

[0002] In the process of human-human interaction, human beings have a very sensitive ability to distinguish facial expressions, especially the gaze direction of human eyes, while machine vision is still at a very low level compared with human vision. Level. The identification of the existing gaze direction ...
