Abstract: A battery assembly for supplying power to an atomizer includes: a battery core have two electrode terminals; an electrical connecting base, two insertion holes being formed on the electrical connecting base, the two electrode terminals being respectively in pluggable fit with the two insertion holes and detachable; and a battery cover. The two electrode terminals form an electrical connection with the electrical connecting base after being inserted into the two insertion holes. The electrical connecting base is electrically connectable to the atomizer. The battery cover detachably covers a side of the battery core facing away from the electrical connecting base.

Abstract: The invention relates to the technical field of image processing, and in particular to a method, a system and a device for acquiring a seaweed bed area, and a storage medium. In the acquisition method, firstly, an initial seaweed bed image with fog is firstly subjected to the fog thickness removal which is convenient for quick calculation, checking whether the quality of the fog thickness removal chart meets the requirements. If the quality of fog thickness removal chart is not up to the standard, a more detailed fog concentration removal method is used to improve the image quality of the initial seaweed bed image until the fog concentration removal chart is up to the standard and then feature extraction is performed. If the quality of fog thickness removal chart is up to the standard, the feature extraction is performed directly.
