Abstract

The invention 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 human face in a detection image; intercepting a target image corresponding to the target part from the detection image according to the detection result of the target part; and according to the target image, identifying whether an object to which the human face belongs executes a set action or not. The embodiment of the invention can be suitable for faces with different areas in different detection images, and canalso be suitable for faces with different facial forms. The embodiment of the invention is wide in application range. Therefore, the target image can comprise enough information for analysis, and theproblem of low system processing efficiency caused by too large area of the intercepted target image and too much useless information can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an action recognition method and device, and a driver state analysis method and device. Background technique [0002] Action recognition has a wide range of applications in the security field. The traditional action recognition technology includes classifying the monitoring images in time series, and then using the key points of the target object in the sorted images to perform action recognition. Due to the small motion range of subtle actions, the effect of using multiple images for subtle action recognition is poor. Contents of the invention [0003] The present disclosure proposes an action recognition technical solution. [0004] According to an aspect of the present disclosure, an action recognition method is provided, the method comprising: [0005] Detect the target part of the face in the detection image; [0006] Intercepting a target image c...
