Smoking behavior detection method based on YoLov5

The invention relates to a smoking behavior detection method based on YoLov5. The method comprises the following steps: shooting through an arranged camera to obtain a real-time monitoring picture; an original YoLov5 network is improved, and an improved YoLov5 network is obtained; detecting a driver face position and a cigarette end position in a monitoring picture by improving a YoLov5 network; performing gesture detection on a driver in the monitoring picture to obtain a driver gesture; smoking behavior characteristics are obtained based on the cigarette end position, the driver face position and the driver gesture detection, so that whether a smoking behavior exists or not is detected. The method has the advantages that whether the driver has the smoking behavior or not is judged according to the combination of the face position of the driver, the cigarette end position, the gesture of the driver and the like through the YoLov5 network, and the smoking behavior of transportation personnel in the transporta
