Example one
In order to improve the operation efficiency when using a video monitoring system and reduce the operation difficulty of the video monitoring system, as shown in fig. 1, a video monitoring system control method is provided in an embodiment of the present invention, and includes the steps of:
s11, generating relative space coordinate data of the whole monitoring area of each camera according to the monitoring video of each camera, and converting the relative space coordinate data of the whole monitoring area of each camera into uniform space coordinate data in the same coordinate system;
the typical application scenario of the embodiment of the invention is that the system comprises a plurality of cameras respectively arranged at a plurality of positions of a monitored place, generally speaking, most monitored areas are provided with more than two paths of cameras for monitoring by shooting monitoring videos; in some areas (e.g., a major monitoring area or an area with more environmental occlusion), there are more cameras to monitor in multiple directions at different viewing angles. At the monitoring control end, an operator can switch the monitoring videos of all the cameras in the interface of the display of the monitoring terminal.
In the embodiment of the invention, firstly, the monitoring video of the camera is utilized to generate the relative space coordinate data of the whole monitoring area of the camera; specifically, the camera head is operated to obtain the monitoring video data of the whole monitoring area including the camera head, and then relative space coordinate data with the camera head as a reference coordinate is generated.
After each camera generates corresponding relative spatial coordinate data according to the whole monitoring area of the camera, further unifying the spatial coordinate data of the monitoring areas of all the cameras into a coordinate system through coordinate system conversion, and further generating unified spatial coordinate data of the monitoring areas of all the cameras; in practical application, the relative spatial coordinate data of the monitoring area in the monitoring video of each camera can be converted into unified spatial coordinate data in the same coordinate system by performing spatial vectorization.
S12, according to unified space coordinate data of a current monitoring area in a monitoring video of a current camera, determining other cameras comprising the current monitoring area as associated cameras of the current monitoring area;
in the embodiment of the invention, the monitoring video displayed by an operator in the interface of the display of the monitoring terminal is called the current monitoring video, and the space area corresponding to the current monitoring video is called the current monitoring area; the camera that generated the current surveillance video is referred to as the current camera.
In the embodiment of the invention, each monitored area corresponds to the unified space coordinate data; therefore, according to the unified space coordinate data of the current monitoring area, the fact that the whole monitoring area of which cameras comprise the current monitoring area can be known; therefore, the space area corresponding to the monitoring video in the display of the operator can be found by which cameras can monitor.
And then, identifying the cameras capable of monitoring the space area corresponding to the monitoring video in the display of the operator as the related cameras.
Further, according to the needs of the operator, after identifying the associated cameras of the current monitoring video, the monitoring video of the current monitoring area shot by the associated cameras at their respective viewing angles can be generated and acquired, specifically, the method may include:
s21, acquiring unified space coordinate data of the current monitoring area and a parameter current value of the associated camera holder;
the camera in the embodiment of the invention is arranged on the cloud deck, and the parameter value of the cloud deck can be adjusted through the control command, so that the rotating angle of the cloud deck of the camera is driven, that is, the orientation of the camera can be adjusted through the control command sent by the control center, and different monitoring areas can be monitored in the whole monitoring area.
After the associated cameras are determined, the current monitoring area of the associated cameras is not necessarily the current monitoring area; therefore, on one hand, uniform space coordinate data of the current monitoring area needs to be acquired to determine the monitoring area needed by the associated camera; on the other hand, the current values of the parameters of the associated camera pan-tilt are also acquired as reference values for driving the pan-tilt rotation amplitude and the rotation direction.
S22, determining a parameter target value of the associated camera holder according to the unified space coordinate data of the current monitoring area;
because each camera has the unified space coordinate data of the whole monitoring area corresponding to the camera, after the monitoring area required by the associated camera is determined, the parameter target value of the associated camera holder is determined according to the unified space coordinate data corresponding to the monitoring area; that is to say, when the parameter of the pan/tilt head of the associated camera is the parameter target value, the monitoring area corresponding to the monitoring video shot by the associated camera is the same as the current monitoring area corresponding to the current monitoring video shot by the current camera.
And S23, generating a control instruction for taking the associated monitoring video shot by the associated camera as the current monitoring area according to the target value and the current value of the pan-tilt parameter of the associated camera.
According to the target value and the current value of the cradle head parameter of the associated camera, the specific numerical values of the cradle head rotation amplitude and the rotation direction can be calculated, and then a control instruction for taking the associated monitoring video shot by the associated camera as the current monitoring area can be generated.
S13, embedding a link icon of a related camera of a current monitoring area in a monitoring video of the current camera;
in the embodiment of the invention, a monitoring video (namely the current monitoring video) in a display of an operator also enters a link icon of a related camera in the current monitoring area; therefore, when the operator observes the current monitoring area through the current camera, the interface also comprises the link icons of all the related cameras in the current monitoring area.
In practical application, the link icon in the embodiment of the invention comprises an identifier of each associated camera or an embedded video playing interface with associated monitoring video; the serial numbers or positions of the associated cameras can be identified by including the identifiers of the associated cameras. The current visual angle of each associated camera can be visually distinguished through the zoomed video of the embedded video playing interface included in the link icon.
S14, switching the associated monitoring video shot by the associated camera corresponding to the link icon into a currently played video according to the trigger event of the link icon in the current monitoring area; the associated monitoring video comprises the current monitoring area.
The link icon in the embodiment of the invention has the important purpose of facilitating the switching of videos by operators, and the corresponding associated camera is selected by the generation mode of trigger events such as mouse clicking or keyboard selection, so that the monitoring video played currently in the display can be switched to the monitoring video of the current monitoring area shot by the corresponding associated camera.
In practical application, the embodiment of the invention can achieve the following use effects: when an operator adjusts the cloud platform of a certain current camera in the interface of the display, the current monitoring area of the current camera can be changed, at the moment, according to the updating of the current monitoring area, a new associated camera (the current camera faces different current monitoring areas and can correspond to different associated cameras) can be determined by acquiring the updated unified space coordinate data corresponding to the current monitoring area, then the updated current monitoring area of the orientation of the newly determined associated cameras can be driven, and further the overall linkage of a plurality of cameras is realized, so that the multi-angle observation and the multi-angle recording of a monitored target are carried out.
It should be noted that, in the embodiment of the present invention, each time the monitoring video of the camera is switched, the camera corresponding to the current monitoring video in the display may be used as the current camera, so that a corresponding link icon is generated by using the technical solution in the embodiment of the present invention, thereby facilitating subsequent view angle switching.
In summary, in the embodiments of the present invention, first, relative spatial coordinate data of an area that can be monitored by each camera is respectively established according to a monitoring video of the camera, and then unified spatial coordinate data of the monitored area of each camera is established through coordinate transformation; therefore, the position of the current monitoring area of the camera in the unified coordinate system can be calculated according to the monitoring video of the camera, and then the current monitoring area can be monitored by other related cameras, so that the specific monitoring object can be observed in multiple directions conveniently through the visual angles of other cameras.
In the embodiment of the invention, when an operator controls a certain camera, a corresponding control instruction can be generated according to the unified space coordinate data of the current monitoring video of the camera, so that other related cameras capable of monitoring the corresponding positions of the unified space coordinate data automatically adjust the cloud deck to face the current monitoring area, thereby not only reducing the process of manual judgment, but also reducing the operation amount and operation difficulty of the operator; further, in the embodiment of the present invention, when an operator needs to observe a current monitoring area through the viewing angles of other associated cameras, the monitoring video shot by the corresponding associated camera can be switched to only according to the link icon of the associated camera in the current monitoring video, so that the control efficiency of the video monitoring system can be effectively improved.
