Embodiment Construction
[0058] In this example, if figure 1 As shown, a real-time monitoring method for pain symptoms of bedridden patients based on expression recognition is carried out as follows:
[0059] Step 1. Establish a pain expression training data set:
[0060] Step 1.1. Set A pain levels from low to high according to the pain grading scale, and collect corresponding pain expression picture data according to different pain levels;
[0061] In the specific implementation, according to the World Health Organization Pain Level Classification Table, the value of A is 5, which is divided into five levels from 0 to IV in turn, corresponding to no pain, mild pain, moderate pain, severe pain, and intolerable five levels. Pain level, and use this to build a data set of pain expression pictures.
[0062] Step 1.2, use the dlib tool to preprocess all the pain expression picture data to obtain an RGB image containing face information of k×k pixels; here, the pixel value k of the picture is 64, and an...
