Navigation mark monitoring method based on video recognition and ship-borne navigation mark intelligent inspection equipment

Abstract

The invention discloses a navigation mark monitoring method based on video recognition and a ship-borne navigation mark intelligent inspection device, which collects standard image information of various types of navigation marks, sets corresponding navigation mark type labels for the standard image information, and extracts the standard image information Corresponding standard coloring information and standard structure information; create a navigation mark recognition model based on the standard image information, standard coloring information, and standard structure information; input the key image frame by extracting the key image frame in the video information of the current navigation mark The AtoN recognition model realizes the intelligent identification of the AtoN type, the coloring state of the AtoN, and the structural state of the AtoN, thereby automatically obtaining the accurate state of the AtoN, facilitating timely maintenance of the faded or structurally damaged AtoN, timely repairing the abnormal AtoN, and improving the usability of the AtoN. Ensure the continuous and stable performance of the navigation mark, promote the transformation of the inspection, maintenance and management of the navigation mark from informatization to intelligentization, and greatly improve the quality and efficiency of the navigation mark inspection.

Description

technical field [0001] The invention relates to the technical field of navigation mark management and monitoring, in particular to a video recognition-based navigation mark monitoring method and equipment applying the method. Background technique [0002] Navigation mark is the abbreviation of navigation aid mark, which indicates the direction of the channel, the boundary and the obstacle, including the river crossing mark, the coastal mark, the guide mark, the transition guide mark, the head and tail guide mark, the side mark, the left and right navigation marks, and the position indication mark , flood marks and bridge and culvert marks, etc. Aids to navigation are set in and around navigable waters to indicate waterways, anchorages, obstructions, shoals, etc., or as signs for positioning and turning, etc., and are also used to transmit signals, such as marking water depth, forecasting weather, and commanding traffic in narrow waterways Wait. [0003] The buoy system is ...
