Third embodiment
A security visualization management method, which relates to invoking a management device to perform security management, as shown in fig. 7 to 8, the management method includes the following steps:
arranging a plurality of sets of management devices so that the first camera 205 of any one management device is positioned in the visual field range of the first camera 205 of the adjacent management device, and the second camera 303 of any one management device is positioned in the visual field range of the second camera 303 of the adjacent management device; after the first camera 205 of any management device is artificially damaged, the first camera 205 of the management device closest to or adjacent to the management device can be remotely adjusted in angle by the control platform to shoot information of the damaged person, so that the management devices cooperate with each other to improve the monitoring stability of the monitoring environment.
When the first camera 205 of any one of the management devices is damaged by human damage, the control platform calls the management device closest to the first camera 205 and adjusts the viewing angle of the first camera 205 above the management device to monitor the real-time image of the damaged first camera 205, so that the monitoring image of the damaged person can be obtained in time through the first camera 205 closest to the first camera to improve the monitoring stability of the monitoring environment. However, when the first camera 205 of the adjacent management apparatus is far away, the first camera 205 of the management apparatus closest to the adjacent management apparatus cannot capture the personal features clear to the broken person; moreover, as the destroying person intentionally destroys the first camera 205, in the destroying process, the face part is often avoided from the monitoring angle of the adjacent or closest first camera 205, so as to prevent the face part from being shot by the adjacent or closest first camera 205; therefore, in order to ensure that the face picture of the person who is damaged can be accurately shot, the method comprises the following steps:
the control platform simultaneously adjusts the visual angle of the second camera 303 of the management device closest to the control platform, then controls the second camera 303 of the management device closest to the control platform to extend out of the management device, and simultaneously calculates the descending height to enable the second camera 303 of the management device closest to the control platform to reach the height position capable of monitoring the personnel destroying the first camera 205; through the operation, the control platform enables the second camera 303 closest to the control platform to shoot the height position of the destructor through remote operation, and calculates and records the descending height of the second camera 303, and the descending height is used for controlling the platform to subsequently control the descending height of the second camera 303 in the destructed management device, so that the face picture of the destructor can be shot quickly and effectively.
The control platform identifies personal characteristics of the destructor according to the picture of the destructor shot by the second camera 303 in the management device closest to the control platform, calls the destructed management device and adjusts the angle of the second camera 303 in the destructed management device; through the operation, the shooting angle of the second camera 303 is adjusted in the management device in advance, and the personal characteristics of the destructor can be rapidly shot after the second camera 303 rapidly extends out of the management device, so that the time for adjusting the shooting angle is saved, and the destructor is prevented from being found and damaged when the shooting angle is adjusted.
The operation steps specifically include the following steps:
the control platform acquires a damaged person picture shot by a second camera 303 in the management device closest to the control platform;
the control platform analyzes the picture of the destructor to judge the position of the destructor relative to the destructed management device and the face orientation of the destructor; through the control of the internal processing software of the platform or the auxiliary judgment, the position of the destructor relative to the damaged management device and the face orientation of the destructor are analyzed, and preparation is made for adjusting the shooting angle of the second camera 303 in the damaged management device.
The control platform calculates the angle alpha of rotation required for the second camera 303 in the damaged management device to horizontally rotate from the initial position to the position facing the face of the damaged person;
the control platform calls the damaged management device and drives the second camera 303 inside the control platform to horizontally rotate by an angle alpha from the initial position to reach the position facing the face of the damaged person, so that preparation is made for shooting the face picture of the damaged person.
The control platform controls the second camera 303 inside the damaged management device to extend out of the management device according to the descending height of the second camera 303 inside the management device closest to the control platform, and controls the descending height of the second camera 303 inside the damaged management device, so that the second camera 303 inside the damaged management device shoots the damaged person, and clear image information of the damaged person is obtained.
Specifically, in order to make the present invention easier to implement, a plurality of sets of management devices are installed in the monitoring environment, the installation heights of the plurality of sets of management devices are all equal, and the height of the second camera 303 in the management device with the control platform damaged is equal to the height of the second camera 303 in the management device closest to the damaged first camera 205, so that on one hand, the mutual cooperation between the first camera 205 and the second camera 303 in the plurality of management devices is realized, and the monitoring stability of the monitoring environment is improved; on the other hand, the first camera 205 and the second camera 303 in the destructed management apparatus and the destructed management apparatus are made to support and associate with each other, which is specifically represented by: when the first camera 205 of one management device is damaged, the first camera 205 of the management device closest to the management device adjusts the angle of view and monitors the damaged first camera 205 to acquire a picture of the damage condition; meanwhile, the control platform controls the descending height of the second camera 303 in the damaged management device and personal characteristics of the damaged person in the shot picture to serve as reference bases, controls the second camera 303 in the damaged management device to adjust the monitoring angle in advance, and controls the descending height, so that the personal characteristics of the damaged person can be rapidly shot after the second camera 303 rapidly extends out of the management device, the time for adjusting the shooting angle is saved, the damaged person is prevented from being discovered and damaged when the shooting angle is adjusted, the accuracy and the reliability of the personal characteristics (such as facial characteristics) of the damaged person are guaranteed to be obtained, the effectiveness of monitoring protection is greatly improved, and the reliability of creating a safe monitoring environment is improved.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
