Abstract: A jujube harvesting apparatus with adjustable suction vector includes: an air duct assembly, where one end of which is arranged with an air duct inlet; a wind power device arranged on one end of the air duct assembly deviating from the air duct inlet and connected to the air duct assembly, where the wind power device is used for generating wind power; an ionization device arranged on the air duct assembly and positioned between the air duct inlet and the wind power device, where the ionization device is used for ionizing air in the air duct assembly to generate plasma; a magnetic field generating device including a first strip-shaped permanent magnet and a second strip-shaped permanent magnet; and a suction vector adjustable device including two moving assemblies, two rotating assemblies, an electromagnetic sensor component, and a control module.

Abstract: A method and an apparatus for generating a video fingerprint are disclosed. The method includes: performing shot boundary detection on content of a video; determining a time duration of each shot according to positional points of the shot boundary, and compose the time duration of each shot into a shot boundary time slice sequence; and obtaining video fingerprint information according to the time slice sequence.
