Problems solved by technology

However, due to the difference between the gun camera and the ball camera equipment, there will be differences between the two even if they are aimed at the same target. In the existing system, it is usually necessary to manually correct the coordinates of the two before collaborative tracking, which requires not only skilled It is operated by personnel, and there is a problem of troublesome adjustment and low precision

Embodiment 1

[0032] The above-mentioned registration process includes the step of starting to count the accumulated registration time; between step E and step G of the registration process, a timeout detection step is also included, and the timeout detection step includes judging whether the registration time exceeds the set time, and if it exceeds , then go to step G, otherwise go to step F.

[0033] By adding timing to the registration process, the adjustment time of the automatic registration process can be controlled from the whole, and the problem of repeated unsuccessful registration due to complex environment can be avoided and the problem of falling into an endless loop can be avoided.

Embodiment 2

[0035] The method for collaborative tracking and monitoring of the trigger and the dome also includes a setting process for the trigger and the dome.

[0036] said Bolt camera and dome camera setup process Including: using a wide-angle camera for the bolt; the distance between the bolt and the ball camera should not be greater than 0.5 meters.

[0037] The hardware part of the usual gun ball system tracking video surveillance system consists of a gun machine and a high-speed ball, both of which can be installed on the wall, column or crossbar. Among them, the shotgun is required to be a wide-angle camera, and there is no special requirement for the high-speed dome. The shotgun can be installed vertically or horizontally according to the actual environment; minimizing the distance between the two can reduce the calibration time. It is recommended that the distance not exceed 0.5 meters.

Embodiment 3

[0039] The method for collaborative tracking and monitoring of the trigger and the dome camera also includes a tracking, monitoring and control process.

[0040] said Tracking, monitoring and control process Include steps:

[0041] A), click / frame any position on the panoramic screen to select the target to be tracked and monitored;

[0042] B), calculate the center coordinates of the click position coordinates / box selection;

[0043] C), calculate the ball machine offset coordinates;

[0044] D), control the rotation and scaling of the speed dome.

Abstract

The invention provides a box camera and ball camera cooperative tracking and monitoring method, The registering process comprises the steps of setting an original point of a box camera, recording the monitoring picture of the box camera and the monitoring picture of a ball camera, calculating the coordinates difference, judging the threshold value, controlling the ball camera and setting an original point of the ball camera. The box camera and ball camera cooperative tracking and monitoring method has the advantages that manual registering operation complexity in the actual application is fully taken into consideration, an intelligent automatic registering method is provided, the simplicity of the operation is improved while the registering precision is improved, and the client experience is better.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method for collaborative tracking and monitoring of a bolt camera and a dome camera. Background technique [0002] In security monitoring, bolt cameras and ball cameras are common cameras. However, in security monitoring, it is difficult to solve the problems of target occlusion and continuous tracking of targets across cameras if only a single gun is used. Specifically, although the above-mentioned center ball machine can flexibly track the target, it has a limited viewing angle, while the gun machine has a wide viewing angle but cannot track the target. [0003] Therefore, it is usually necessary to implement tracking and monitoring by using multiple cameras and coordinating between multiple cameras, so as to achieve the purpose of expanding the observation range and increasing the observation angle of the monitoring system. As a result, the accuracy of target dete...
