Embodiment Construction

[0014] Such as figure 1 As shown, it is a structure diagram of a preferred embodiment of the network camera correction system of the present invention. The network camera calibration system 11 (hereinafter referred to as “calibration system 11 ”) runs in the network camera 1 . The network camera 1 includes a monitoring unit 10 , a processor 12 , an alarm unit 13 and a communication unit 14 .

[0015] The monitoring unit 10 is used to monitor the three-axis (X, Y, Z) gravitational acceleration value of the network camera 1 in the preset coordinate system. The monitoring unit 10 may include a gravity sensor, for example, a G-sensor (acceleration sensor). The monitoring unit 10 may also include an orientation sensor, such as an electronic compass, for monitoring the orientation parameters of the network camera 1 , such as the azimuth and pitch angle of the network camera 1 .

[0016] The processor 12 is used to execute the program codes of each program segment in the correctio...

Abstract

A method for calibrating a network camera, the method comprising: regularly reading the acceleration of gravity value sensed by the gravity sensor in the network camera; when the acceleration of gravity value is different from the preset acceleration of gravity, judging whether the current acceleration of gravity value exceeds The preset critical value; when it is determined that the current acceleration of gravity value exceeds the preset critical value, it is judged whether the acceleration of gravity value of the network camera has undergone continuous and irregular changes; when it is determined that the acceleration of gravity value of the network camera has sustained and irregular changes When changing, the alarm unit controlling the network camera sends out an alarm using a preset alarm mode. The invention also provides a network camera correction system. The invention can timely and conveniently correct the network camera.

Description

technical field [0001] The invention relates to a calibration method, in particular to a network camera calibration system and method. Background technique [0002] Network camera is a new generation of camera produced by combining traditional camera and network technology. The manager can check the situation of the camera through the local area network or the Internet. At present, network cameras are of great significance to the security of enterprises and families. However, if a traditional network camera is displaced or moved by an external force, this situation is often not detected immediately, and further corrective measures cannot be taken in a timely manner. required screen. Contents of the invention [0003] In view of the above, it is necessary to provide a network camera calibration system and method, which can use the monitoring unit to monitor the state changes of the network camera in real time and perform correction in time. [0004] A network camera cal...
