The monitoring client switches to the corresponding camera channel according to the response message returned by the switching server.

A specific embodiment of a video surveillance scenario switching method provided by the present invention is described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a video surveillance scenario switching method according to an embodiment of the present invention. As shown in FIG. 1 , the video surveillance scenario switching method provided by this embodiment includes the following steps:

Step S101: monitoring the front end camera pair of the camera channel currently monitored by the client is monitored The area is monitored in real time, and when there is a monitoring object moving into the monitored area, the monitoring client is notified.

The monitored area can be delineated by a warning line set in advance on the upper, lower, left, and right boundaries of the range monitored by the front-end camera, and these warning lines are displayed correspondingly on the display screen of the monitoring client.

Step S102: The monitoring client prompts the user to issue an operation instruction indicating a moving direction of the monitoring scene.

In this step, the user issues an operation instruction that coincides with the moving direction of the monitoring object according to the prompt. For example, when the monitoring object moves to the lower side of the screen, an operation instruction indicating downward movement is issued.

Step S103: The monitoring client receives an operation instruction sent by the user to indicate a moving direction of the monitoring scene, and queries whether the front camera of the currently monitored camera channel has a PTZ control function; if yes, execute S104; if not, execute S105.

Since the front camera of the camera channel currently monitored by the monitoring client may have the function of pan/tilt operation, it may not have the function of pan/tilt operation. Therefore, after the monitoring client receives the operation instruction from the user indicating the direction of movement of the monitoring scene, further inquiry is needed. Whether the front camera has PTZ operation function.

Step S104: The monitoring client continues to determine whether the monitored object has moved out of the set monitored area. If not, the process proceeds to step S106; if it has been removed, the process proceeds to S105.

Step S105: The monitoring client initiates a channel switching request to the switching server.

In the channel switching request, the corresponding switching direction information is included, and the switching direction is consistent with the direction indicated in the operation command issued by the user.

Step S106: The monitoring client performs corresponding pan/tilt operation on the front end of the camera channel of the monitored camera channel according to the received operation instruction.

For example, when the monitoring client receives the downward operation instruction from the user, the pan head operation is performed on the front end camera hair, and the angle of the front camera after the operation is adjusted downward by a certain angle. 2 is a flowchart of monitoring a client to initiate a channel switching request to a switching server according to an embodiment of the present invention.

Set a main camera channel. When the main camera channel selection fails, select the secondary camera channel; that is, set the priority between each camera, and select them in order of priority.

In the second way, the orientation of the plurality of camera channels is further divided so that there is only one camera channel in each orientation. In this case, the monitoring client also needs to be in the direction indicated by the user's operation instruction (upward, Down, left, or right), further analyze the movement angle of the monitored object, and notify the switching server through the channel switching request, switching the server root Selecting the corresponding camera channel according to the channel switching request;

In the third way, the list of all camera channels in the direction is returned to the monitoring client, and the user selects in the list through the display interface.

Step S202: The switching server notifies the selected client to the monitoring client by using a response message.

Here, the switching server is not limited to notifying the selected client via the response message to the monitoring client.

Step S203: The monitoring client switches to the corresponding camera channel according to the response message returned by the switching server.

In the third mode described in step S201, when the switching server selects multiple camera channels, the monitoring client provides the information of the plurality of camera channels in the response message to the user for selection, and according to the user selected one. The information of the camera channel is switched to the corresponding camera channel.
