Behavior recognition and action detection recognition method and system based on double-flow CNN

The embodiment of the invention provides a behavior recognition and action detection recognition method and system based on a double-flow CNN, and belongs to the technical field of computer vision. The identification method comprises the following steps: acquiring optical flow information and image information of field camera equipment; according to the optical flow information and the image information, a convolutional neural network is adopted for calculation, so that the recognition probability of the field action is obtained; and selecting the field action with the maximum identification probability average value as an identification result. According to the technical scheme, the behavior recognition and action detection recognition method and system based on the double-flow CNN, provided by the invention, perform calculation and distribution by collecting the optical flow information and the image information of the site and combining the two neural networks, and realize accurate detection of behaviors a
