Construction area safety monitoring method

The invention discloses a construction area safety monitoring method which comprises the following steps: acquiring a picture, judging whether the acquired picture is a construction dangerous area or not, and fixing the pose of a camera at the same time; marking objects with different semantic category features in the picture belonging to the construction dangerous area by using a neural network, and marking different colors; after the pose of the camera is fixed, video shooting is started, a certain frequency is set to intercept the video, and an image obtained through interception is sent to a neural network to be processed; when the neural network processes the intercepted picture, a constructor or an object entering the construction dangerous area is marked as a specific color; and calculating an overlapping region with different colors marked by semantic categories in the specific color area region and the original construction dangerous region to obtain the position of a person or an object entering the
