Embodiment 1
[0088] In this embodiment, the above method is described by taking the classroom environment of primary and middle school students as an example. Collect 40,000 samples and make hand samples in the format of the PASCALVOC dataset. Through the clustering of the sample size, the final clustered 9 anchor box sizes are:
[0089] (37,59)(44,72)(53,80)(56,96)(67,105)(75,128)(91,150)(115,184)(177,283).
[0090] The training process in this embodiment has been iterated a total of 20,000 times, and a hand-raising detection model with better effect is obtained. Some renderings of the trained hand-raising detection model are as follows: Figure 7 shown.
[0091] After using the tracking algorithm to combine different frames of hand-raising movements, count the number, record the number of hand-raising movements in the entire classroom, and complete the count of hand-raising movements in a classroom, so as to evaluate the classroom atmosphere and provide a basis for the classroom atmos...
