Embodiment Construction
[0028] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.
[0029] refer to Figure 1-3 , a classroom student behavior detection method, the method comprises:
[0030] Convert the original image of the classroom students to a grayscale image;
[0031] Input the grayscale image into the deep learning model to detect the head and shoulders frame and identify the lying table, and obtain the head and shoulders frame;
[0032] Determine the hand-raising detection area according to the head-and-shoulder frame, and perform hand-raising detection in the hand-raising detection area.
[0033] According to the formula:
[0034] f(i,j)=0.2999R+0.587G+0.114B,
[0035] Perform grayscale processing on the original image to obtain a grayscale image, where f(i,j) is the grayscale value of the pixel at the image coordinates (i,j) after grayscale, and R, G, and B are the color image RGB respectively Three-componen...
