The invention provides a video key frame extraction method and device, equipment and a storage medium, and the method comprises the steps: obtaining an original frame sequence of an input video; performing content analysis on the original frame sequence, and identifying whether a user-defined attention target exists or not; if the concerned target is not recognized, selecting a key frame from the original frame sequence according to a preset extraction strategy; and if the attention target is identified, constructing a candidate frame set based on the frames containing the attention target and calculating visual difference measurement among the frames in the candidate frame set, and selecting a key frame from the candidate frame set based on the visual difference measurement and outputting the key frame. By adopting the method, the key frame extraction efficiency, pertinence and information density can be improved, and the accuracy of subsequent video analysis is further improved.

This invention provides an electrode rod for multipole ion transport, comprising a rod body. In a cross-section perpendicular to the axis of the rod body, the rod body includes a curved section, a mounting section, and a transition section for extending the distance between the curved section and the mounting section. The curved section has a bent surface for forming an electrode field. The mounting section is located opposite to the bent surface and is used for positioning and mounting. The transition section extends along the opposite direction of the bent surface and connects to the mounting section. A multipole assembly is also provided, including a fixing member and at least two pairs of electrode rods positioned and mounted by the fixing member. This invention provides an electrode rod and a multipole assembly for multipole ion transport, ensuring both convenient installation and ion focusing capability when the number of electrode rods increases.
