Problems solved by technology

Pain is regarded as an important indicator in medicine. Correctly judging pain can make treatment more effective. The gold standard for pain detection is the patient's "self-report". However, this is not a method that is applicable to all patients. Feelings and judgments are subjective, and reporting of the scale may vary significantly between individuals

Abstract

The invention discloses a facial pain expression recognition method and system based on depth information. The method comprises the following steps: establishing a pain expression data set containing the depth information; preprocessing the acquired pain expression data set; inputting the preprocessed pain expression data set into a frame attention network for training to obtain a pain grading model, wherein the frame attention network comprises a feature embedding module and a frame attention module; and sending expression data which are acquired in real time and preprocessed to the pain grading model for identification, and judging whether to carry out alarm processing according to an identification result. According to the invention, abnormal state detection can be stably carried out on the identified target, early warning can be timely sent to a worker, and the method has great practical value in the fields of public medical treatment, smart old-age care and the like.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a facial pain expression recognition method and system based on depth information. Background technique [0002] The International Association for the Study of Pain defines "pain" as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or a description of such damage". Pain is regarded as an important indicator in medicine. Correctly judging pain can make treatment more effective. The gold standard for pain detection is the patient's "self-report". However, this is not a method that is applicable to all patients. Feelings and judgments are subjective, and reporting of the scale may vary significantly between individuals. Behavioral observation of patients, particularly facial expressions, as key behavioral indicators of pain assessment, has been identified as an important way to assess pain, especially when the ...
