Abstract

The invention provides a face expression recognition method and device and a storage medium, and the method comprises the steps: obtaining a target face image of a to-be-detected target, extracting face key points of the image, determining the position relation between the key points, and inputting the face key points and the position relation into a face expression recognition model, therefore, the facial expression of the to-be-detected target is recognized by using the facial expression recognition model. According to the embodiment of the invention, face expression recognition is carried out based on the face key points, the problem of information redundancy of the face picture is solved, the face expression recognition accuracy is improved, the data input speed is high, and the face expression recognition time of the face expression recognition model is shortened. Besides, the position relationship is input into the preset facial expression recognition model, so that the information of the to-be-detected target input into the preset facial expression recognition model is richer, and the accuracy of the subsequent facial expression recognition result of the to-be-detected target is further improved.

Description

technical field [0001] The present application relates to image processing technology, in particular to a facial expression recognition method, device and storage medium. Background technique [0002] With the continuous development of economy and technology, people's travel methods are becoming more and more diversified, such as traveling by operating vehicles such as taxis and online car-hailing. However, while the above-mentioned travel methods bring convenience to people, some new problems also arise. For example, taking online car-hailing as an example, when the vehicle is driving, the driver may drive the vehicle in an abnormal state, such as driving the vehicle in an angry state, so that passengers have a certain degree of safety in the daily travel process of using the online car-hailing car. Hidden danger. [0003] In order to solve the above problems, in the related art, usually, the terminal device collects the face image of the driver, and performs facial expre...
