Navigation mark identification method and device based on video inspection, and storage medium

The invention discloses a navigation mark identification method and device based on video inspection and a storage medium. The method comprises the following steps: establishing a navigation mark data table for each navigation mark; performing multiple times of image acquisition on each navigation mark, wherein all the acquired images of each navigation mark form an image material package; recording first image acquisition data corresponding to each acquisition image, binding the first image acquisition data and the first image acquisition data, and storing the bound data in a navigation mark data table; obtaining current image acquisition data, and calculating a difference value between the current image acquisition data and the first image acquisition data in each navigation mark data table; obtaining the minimum value and querying the navigation mark corresponding to the minimum value as an identification object; traversing the image material package of the recognition object, and determining a reference i
