Abstract

The invention provides a driver face detection method, a computer device and a computer readable storage medium. The driver face detection method comprises the steps of obtaining a frame of image andinputting the image to a detection network unit, wherein the detection network unit comprises multiple stages of detection modules, and each level of detection module acquires a plurality of face candidate areas and performs non-maximum suppression calculation; calculating the intersection-parallel ratio of the face candidate region with the highest classification score in the face candidate regions output by the detection module to the detection region of the historical information; when the cross-parallel ratio is smaller than a cross-parallel ratio threshold value, applying a next-stage detection module to detect the face candidate area output by the current-stage detection module; and when the cross-parallel ratio is greater than the cross-parallel ratio threshold value, and after non-maximum suppression calculation is performed on the face candidate area output by the current-level detection module, outputting a calculation result of the current-level detection module when the number of the output face candidate areas is not more than one. The invention further provides a computer device and a computer readable storage medium for implementing the driver face detection method.According to the driver face detection method, the calculation amount of face detection can be reduced.

Description
