Driving method for monitoring camera based on rotary motor

Abstract

There is no surveillance camera system optimum for monitoring an important monitor place by a surveillance camera mainly for crime prevention day and night without humans in attendance, which can automatically monitor the place without humans in attendance and, when something suspicious is found, follow the suspicious without humans in attendance, and accurately monitor the suspicious at high precision. The present invention provides a surveillance camera driving method achieving such a system having the function of obtaining video image signals by two or more surveillance cameras each having a three-dimensional positioning pan tilt head function, organically processing the video information, comparing the processed information with input data of a plane picture or the like or data of pictures of a front view and a side view or the like, and determining whether the processed video signal is the same as the input data or not.

Description

technical field [0001] The present invention relates to a method of driving a surveillance camera by a rotating motor which is most suitable for driving the surveillance camera. Background technique [0002] In the case of unmanned monitoring of important surveillance locations day and night through a surveillance camera with the main purpose of prevention, a surveillance camera device that can be positioned in three dimensions is necessary. Therefore, a panning motor that rotates horizontally and passes through This motor drives the camera horizontally, while the camera is driven by a tilt motor that swings the camera vertically. [0003] Fig. 4 is a block diagram of a conventional three-dimensional positioning monitoring camera. 31 is a motor driving the horizontal shaft, 32 is its output pinion, 33 is a reduction gear meshing with it, and 35 is a cylindrical shaft used for the horizontal rotation of the video camera 10, which is supported by a bearing 34 with a large inn...

Problems solved by technology

[0005] However, if you do not use a slip ring, if you continue to rotate several times in one direction, the wires and cables that supply power to the tilt motor or camera will be twisted together, making it impossible to rotate.

Even if a slip ring is used, if the horizontal rotation axis of the rotating motor and the horizontal rotation axis of the camera are not concentric, the structure will be complicated, the shape will be large, and the camera will be conspicuous, so it may not be suitable for this purpose.

[0006] Using surveillance cameras mainly for the purpose of prevention, in order to monitor important surveillance locations day and night without people, use the most suitable surveillance camera device to perform automatic surveillance without people. There is no such surveillance camera device that can continuously track suspicious situations and accurately monitor with high precision, and the development of a surveillance camera drive method that can solve these problems has become a problem
