[0071] Example: The implementation of a statistical method for store entry rate based on yolo and centroid tracking is as follows:
[0072] (1) Select experimental data
[0073] The experimental data selected by the present invention is the video of the flow of people in the experimental building collected by ourselves, with a duration of 5 minutes, recording the people passing by the door of the experiment and the flow of people entering and leaving the experimental building within this hour.
[0074] The present invention uses the YOLOv3 model. First, the image needs to be preprocessed, and the resolution of each input frame image is adjusted to 416*416. as attached figure 2 , The feature extraction network used by YOLOv3 is DarkNet53. This network is superimposed by residual units, which greatly reduces the difficulty of training deep networks. Unlike the previous YOLO version, YOLOv3 performs prediction tasks from feature maps of three different scales. The input image ...
