Automatic tracking holder and camera shooting system

Abstract

The invention discloses an automatic tracking holder and a camera shooting system. The automatic tracking holder comprises a shell and a cover. A horizontal rotation driving mechanism and an up-down rotation driving mechanism are arranged in the shell. The up-down rotation driving mechanism comprises an up-down rotation drive motor with a first driving gear and an up-down rotation transmission assembly. The up-down rotation transmission assembly comprises two fixing bases and two rotation pieces. Each rotation piece is provided with a swing arm. At least one swing arm is provided with a rotation gear which is in meshing transmission with a first gear on a rotation disc. A second gear on the rotation disc is in transmission connection with the first driving gear. The automatic tracking holder is further provided with a first elastic component making the first driving gear make tight contact with the second gear. Due to the arrangement of the first elastic component making the first driving gear make tight contact with the second gear, the requirement for matching precision between the components is lowered, the component machining difficulty is lowered , meanwhile, noise and shaking caused by the too large or too small fit clearance are avoided, and running stability is improved.

Description

technical field [0001] The invention relates to the technical field of camera pan-tilts, in particular to an automatic tracking pan-tilt and camera system. Background technique [0002] Existing cloud platforms are widely used in the field of video surveillance, although the existing cloud platforms can realize multi-angle movement, such as horizontal rotation. It can rotate up and down again, and can also rotate up and down while rotating horizontally, but its structure is complicated when realizing horizontal rotation and up and down rotation, and the volume is relatively large. At the same time, the processing precision of the transmission parts of the gimbal is high, that is, the precision of the cooperation between the transmission parts is high, otherwise it is easy to appear. When the gap between the transmission parts is too small, it is easy to appear stuck during operation, causing the collected video image to shake. Discontinuity and other phenomena; when the mat...

It can also rotate up and down, and it can also rotate up and down while rotating horizontally, but its structure is complicated when it realizes horizontal rotation and up and down rotation, and its volume is large

At the same time, the processing precision of the transmission parts of the gimbal is high, that is, the precision of the cooperation between the transmission parts is high, otherwise it is easy to appear. When the gap between the transmission parts is too small, it is easy to appear stuck during operation, causing the collected video image to shake. Discontinuity and other phenomena; when the matching gap between moving parts is too large, it will also cause jitter and other phenomena in the collected video image, and the noise is relatively large during operation
