Embodiment Construction

[0091]In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0092]In the background art, when the surveillance area of ​​a camera is calibrated, manually re-adjusting the position of the camera to realize the adjustment of the surveillance area of ​​the camera is specifically divided into two types. One is to manually adjust the installation of the camera. It is time-consuming and labor-intensive, and it is more restricted by the environment, which is prone to the problem of delay in the calibration of the monitoring area; the other is that the camera comes with a two-axis motor, such as a dome, which requires manual control of the two-axis rotation of the motor. Drive the position adjustment of the camera to adjust the monitoring area of ​​the camera. This method still requires manual participation, and the prob...

Abstract

The invention discloses a monitoring area calibration device for a camera, and the device comprises the steps: recording the reference position of the camera when the monitoring area of the camera accords with a preset monitoring area; acquiring a real-time position of a camera, and comparing the real-time position with the reference position; and when the deviation position value is obtained through comparison, adjusting the position of the camera according to the deviation position value so as to enable the monitoring area of the camera to accord with a preset monitoring area. Therefore, theembodiment of the invention can automatically calibrate the monitoring area of the camera in real time.

Description

Technical field[0001]The invention relates to the field of automatic control, in particular to a camera monitoring area calibration device.Background technique[0002]With the development of surveillance technology, cameras, such as network cameras (IPC) or dome cameras, will be installed in areas that need to be monitored. After the camera is set up, in the process of monitoring its set monitoring area, due to its own gravity factors or vibration factors, the position of the camera will shift, such as sagging, etc., which will change its monitoring area, which will not The set monitoring area is different. In this case, it is necessary to calibrate the position of the camera from time to time so that the surveillance area of ​​the camera remains unchanged.[0003]At present, to calibrate the surveillance area of ​​the camera, manually re-adjust the position of the camera to realize the adjustment of the surveillance area of ​​the camera. Using this method is time-consuming and labor-in...
