Focusing driving motor device of smart dome camera, and focusing method

Abstract

The invention relates to a focusing driving motor device of a smart dome camera. The device comprises a controller arranged in a dome camera body, and the controller is connected with a background computer, a network module, a first stepping motor, a second stepping motor, a nine-axis gyroscope and a geomagnetic sensing module. A focusing method of the focusing driving motor device of the smart dome camera comprises the following steps: 1) setting an initial viewing angle of the dome camera; 2) sending, by the background computer, a viewing angle adjustment command; 3) adjusting, by the dome camera, the viewing angle according to the instruction of the background computer. The focusing driving motor device provided by the invention has the advantages of good imaging effect, rapid response,flexible configuration, capable of saving the input of the dome camera, and clear imaging.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional vision imaging, and in particular relates to a focusing drive motor device and a focusing method of an intelligent dome camera. Background technique [0002] Smart dome camera is a representative of the development of modern video surveillance. It integrates multi-functions such as color integrated camera, pan / tilt, decoder, and protective cover. It is easy to install, simple to use but powerful in function, and is widely used in the monitoring of open areas. It can be used in different occasions. [0003] The smart dome camera is a product with a high degree of integration. It integrates the pan-tilt system, communication system, and camera system. The pan-tilt system refers to the rotating part driven by the motor. The communication system refers to the control of the motor and the image and the signal processing part, the camera system refers to the all-in-one movement used; and the ...

Problems solved by technology

[0004] However, the geographic positioning and angle adjustment of the current smart dome cameras are not accurate enough. The dome camera cannot be automatically calibrated, and the slight deviation of the dome camera will cause a large image quality deviation during long-distance monitoring, which will affect the shooting effect of the smart dome camera; moreover, the current smart dome camera is locking the target object. When shooting, the adjustment angle is not accurate enough, and the sensitivity is not high, which will also lead to a large deviation in the image quality of the shot, which will affect the shooting effect of the smart dome camera
