Micro-expression recognition method and device and computer readable storage medium

The invention discloses a micro-expression recognition method and device and a computer readable storage medium, and the method comprises the steps: extracting a first optical flow feature and a second optical flow feature from a to-be-processed video, the to-be-processed video comprises at least one target, the region where the target is located comprises a face region, the face region comprises a region of interest and a rigid region, and the region of interest comprises a first optical flow feature and a second optical flow feature; the first optical flow feature is the feature of a region of interest, and the second optical flow feature is the feature of a rigid region; based on the second optical flow feature, correcting the first optical flow feature to obtain a third optical flow feature; and performing expression recognition processing on the third optical flow feature by using a micro expression recognition model to obtain a first expression recognition result. In this way, the micro-expression recog
