Title:
ACTION RECOGNITION METHOD AND DEVICE, AND DRIVER STATE ANALYSIS METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/062969
Kind Code:
A1
Abstract:
The present disclosure relates to an action recognition method and device, and a driver state analysis method and device. The action recognition method comprises: detecting a target part of a face in a detection image; cropping, according to a detection result of the target part, the detection image to obtain a target image corresponding to the target part; and recognizing, according to the target image, whether an object, to which the face belongs, performs a set action. The embodiments of the present disclosure are applicable to faces of different areas in different detection images, and are also applicable to faces of different shapes. The embodiments of the present disclosure are applicable in a wide range. The target image can include enough information for analysis, or can also alleviate the problem of low system processing efficiency due to the cropped target image having a too large area and too much useless information.
