The invention is suitable for the technical field of monitoring and provides a video monitoring method and device for a pipe gallery channel. The method comprises the following steps of obtaining a monitoring picture in the pipe gallery channel as a reference video frame through video monitoring equipment; determining an area of interest which is selected in the reference video frame by a user; carrying out binarization processing on the reference video frame and a real-time video frame obtained by the video monitoring equipment; comparing the reference video frame and the real-time video frame after binarization processing and computing the number of pixel variations of the area of interest; and if the number of pixel variations exceeds a first preset threshold, triggering the alarm. The video monitoring equipment is arranged in the pipe gallery channel, and the video monitoring of the pipe gallery channel is completed through comparing the reference video frame and the real-time video frame, so that the troubleshooting of each engineering pipeline in the pipe gallery channel can be carried out remotely, and thus the efficiency for troubleshooting is improved.
Description
technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a video monitoring method and device for a utility tunnel. Background technique [0002] The pipe gallery is a structure and ancillary facilities built underground to accommodate two or more types of urban engineering pipelines. It can integrate various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage, and is a guarantee for urban operation. critical infrastructure. [0003] Since the on-site environment of the pipe gallery tunnel is relatively closed, it is not conducive for engineers to check the environmental conditions in the pipe gallery tunnel in time when a fault occurs or there is a hidden danger of failure, which affects the efficiency of troubleshooting. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a video monitoring method and device for a utility...
