Video retrieval device based on big data service and using method of video retrieval device

Abstract

The invention discloses a video retrieval device based on big data service. The video retrieval device comprises a base, a motor is fixedly installed on the top face of the base, a fixing plate is fixedly installed at the top end of an output shaft of the motor, one ends of cameras are hinged to one sides of long-strip shaped boxes, one ends of two connecting rods located between the two cameras are hinged to the middles of the opposite faces of the two cameras correspondingly, first chain wheels are fixedly installed at the top end of a worm, a second chain wheel is fixedly installed at the top end of an output shaft of a forward and reverse rotation motor, and the two first chain wheels are movably connected with the second chain wheel through a chain. According to the device, the face of a pedestrian can be shot at all angles folded by the cameras, the pedestrian breaking traffic rules can be better recorded, shooting recording is achieved, the shooting effect is better, when the upper connecting rod returns to the initial position, the upper connecting rod is pushed towards the direction of a through groove through the elastic force of a spring, and the structure of the connecting rods is more stable through limiting and supporting of a circular ring.

Description

technical field [0001] The invention belongs to the field of video retrieval, in particular to a video retrieval device based on big data service and a method for using the same. Background technique [0002] In recent years, pedestrian retrieval (also known as pedestrian re-identification (Pedestrian re-identification)) has become a hot topic that is both valuable and challenging. [0003] With the needs of the society, more and more monitoring systems composed of large-scale camera networks are deployed in public spaces such as airports, shopping centers, banks, stations, docks, campuses, squares, office buildings, and residential areas. These geographical spaces span a large A network of cameras with non-overlapping fields of view provides people with very large video data. By analyzing such video data with a video retrieval device, a specific target person can be retrieved therefrom—for example, a person who has been previously specified by a certain camera or a person ...
