Abstract
The present disclosure provides a method for detecting the focus of attention. The method includes: obtaining the face of a person in the first image, as well as the result of facial recognition; determining whether the distance between the person and the target is within an effective attention range; determining whether the face is frontal; determining whether the effective attention period is not shorter than a period threshold; detecting the focus of attention for the person to the target.
