The embodiment of the invention provides a human body behavior identification method and device. The method comprises the steps that a graphical user interface (GUI) is provided, the GUI is used for displaying a control panel and a display panel, the control panel comprises a network loading button, an image loading button and an identification button, and the display panel is used for displayinga to-be-identified image and a behavior identification result; if it is monitored that the network button is triggered to be loaded, a pre-trained GoogLeNet model is loaded; if it is monitored that the image loading button is triggered after the GoogLeNet model is loaded, displaying the image in a display panel after the image to be identified is received; and if the image is displayed on the display panel and the trigger identification button is monitored, the image is inputted to be identified into the GoogLeNet model, a behavior identification result is outputted and the behavior identification result is displayed in the display panel. When the GUI is constructed, the human body behavior recognition process can be displayed directly and the purpose of repeated recognition can be achieved only by loading the model once during application.
