The present invention relates to an emergency shooting apparatus and method of a surveillance camera, for example, in a specific place where a PTZ surveillance camera equipped with a Pan, Tilt, Zoom function is installed, The emergency situation photographing apparatus of a surveillance camera for distributing and installing a temperature detection sensor, a gas detection sensor, and the like, and for monitoring and photographing a main position preferentially when an emergency occurrence is detected by the detection sensors. And to a method.

Generally, a PTZ surveillance camera equipped with a pan / tilt / zoom function is mounted on a pan & tilter fixedly installed on a ceiling of a specific place, for example, as shown in FIG. 1. The PTZ monitoring camera 100 may move the surveillance area to another direction by a panning operation rotated in the horizontal direction by the pan / tilt 200 and a tilting operation rotated in the vertical direction. Can be changed.

In addition, in the PTZ surveillance camera, the zoom lens may be variably adjusted in a tele or wide direction to enlarge or photograph a subject, and to capture the captured video image. As shown in FIG. 1, the digital video recorder 300 is located at a remote place.

On the other hand, the digital video recorder 300 outputs and displays the video image photographed by the PTZ surveillance camera through a monitor screen and records it on a hard disk (HDD) included in the device. For example, an administrator who monitors a corresponding region through the monitor screen may arbitrarily remotely control a pan / tilt angle of the pan / tilt 200 to control the PTZ camera. When the photographing angle of 100 is a desired specific angle, it is set as a preset.

In the digital video recorder 300, when the administrator selects and selects a preset number from among a plurality of presets, the pan and tilt angles stored in association with the preset number are read out. Pan / tilt operation of the pan / tilter 200 is controlled, and the pan / tilter 200 controls the pan / tilter 200 so that the shooting angle of the PTZ camera 100 is a preset shooting angle. Since the tilt operation is performed, an administrator located at a remote location may monitor and check a video image at a desired shooting angle by using preset information that is pre-stored and managed.

On the other hand, after installing a detection sensor (Sensor) for detecting whether the door is opened or closed at a location such as an entrance door or window in a specific place where the PTZ camera 100 is installed, the detection signal is output by the detection sensor In this case, in the digital video recorder, the pan angle and the tilt angle of the pan / tilter 200 are variably adjusted so that the photographing angle of the PTZ surveillance camera 100 faces the position where the corresponding detection sensor is installed. Or, an intruder who intrudes through a window or the like is monitored and photographed.

However, when an emergency situation such as a fire or gas leak occurs in a specific place where the PTZ surveillance camera is installed, the main location where the emergency situation occurs is first determined automatically, and the corresponding position is quickly determined. Since there is not yet a solution to be able to shoot and monitor quickly, it is urgently required to prepare an effective solution.

Therefore, the present invention was created in view of the above circumstances, and for example, distributed a plurality of temperature detection sensors or gas detection sensors in a specific place where a monitoring camera is installed, and in addition to the detection sensors. When the occurrence of an emergency situation is detected, the detection values output from the respective detection sensors are compared with each other to determine the priority (Priority_Order) for the main positions where the emergency situation occurs, and then sequentially change the photographing angle of the surveillance camera. And to provide an emergency situation shooting apparatus and method of the surveillance camera for taking a picture, to be able to quickly and more efficiently cope with an emergency situation, the object is to.

Emergency situation shooting method of the surveillance camera according to the present invention for achieving the above object, a step of comparing the detection values output from a plurality of sensors distributed in different locations; Determining photographing priorities of the surveillance cameras according to the magnitudes of the detection values; And three steps of variably controlling the rotation operation of the pan / tilt on which the surveillance camera is mounted according to the determined shooting priority.

In addition, the emergency shooting apparatus of the surveillance camera according to the present invention, the surveillance camera for photographing a specific place; A pan / tilter on which the surveillance camera is mounted; A plurality of sensors distributed in different locations in the specific place; And a digital video recorder for determining the shooting priority of the surveillance camera according to the magnitude of the detection values output from the plurality of sensors, and then variably controlling the rotation operation of the pan / tilt according to the shooting priority. Characterized in that comprises a.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the emergency shooting apparatus and method of the surveillance camera according to the present invention will be described in detail.

2 is a view illustrating a state in which a pan / tilt equipped with a surveillance camera and a plurality of sensors are connected and connected to a digital video recorder to which the present invention is applied. For example, the digital video recorder 300 may include an interface unit. 30, the CPI 31, the HDR (HDD Record) system 32, the hard disk 33, the OSD generator 34, and the memory 35 may be included.

On the other hand, through the interface unit 30, the surveillance camera 100 mounted on the pan / tilter 200 is connected and connected, and distributed installation in different locations in a specific place where the surveillance camera 100 is installed A number of detection sensors, for example gas detection sensors or temperature detection sensors 400, 401, 402, may be connected.

In addition, as shown in FIG. 3, the CPI 31 stores and manages a plurality of preset information arbitrarily set by an administrator in the memory 35. For example, a first detection sensor may be used. The pan angle 0 degrees and the tilt angle 30 degrees for capturing the position where the # 1) is installed are stored and managed as the first preset (Preset # 1) together with the first detection sensor number, and the second detection sensor (Sensor # 2) The pan angle -45 degrees and the tilt angle 20 degrees for capturing the installed position, together with the second detection sensor number, are managed as a second preset (Preset # 2), and a third detection sensor (Sensor # 3) is installed. The pan angle +45 degrees and the tilt angle 25 degrees for capturing the position are stored and managed as a third preset (Preset # 3) together with the third detection sensor number.

In addition, when performing an automatic preset monitoring operation (Auto Preset Monitoring) at the request of the administrator, the pan / tilt 200 at the pan / tilt angle of the first preset stored and managed in the memory 35. Operation control, and then operation control of the pan / tilt 200 at the pan / tilt angle of the second preset, and operation control of the pan / tilt 200 at the pan / tilt angle of the third preset. A series of automatic preset monitoring operations are performed sequentially.

On the other hand, in the CPI 31, for example, while the surveillance camera 100 is photographing the position corresponding to the first preset (Preset # 1), the detection signal from the third detection sensor (Sensor # 3) Is output, it is determined that an emergency situation has occurred at the position where the third detection sensor is installed, and the operation of the pan / tilter 200 is performed to control the third preset (Preset # 1) in which the third detection sensor is installed. The location corresponding to the is taken.

In addition, when a detection signal is output from both the third detection sensor # 3 and the second detection sensor # 2, the priority signals Priority_Order are compared in order of increasing signal magnitude. After the determination, the operation of the pan / tilter 200 is sequentially performed according to the priority, and the main part of the emergency situation is photographed first, which will be described in detail as follows.

FIG. 4 is a flowchart illustrating an emergency shooting method of the surveillance camera according to the present invention. As described above, in the CPI 31, the surveillance camera 100 is requested by an administrator. After arbitrarily variably adjusting the pan angle and tilt angle of the mounted pan / tilt 200, the pan angle and tilt angle are stored in association with the preset information.

Meanwhile, as described above with reference to FIG. 3, the preset information includes a unique number of a detection sensor installed at a position corresponding to each preset information, for example, a temperature detection sensor installed to detect a fire occurrence. ) May be linked together and recorded (S10).

In addition, when the CPI 31 performs an automatic preset monitoring operation at the request of the administrator, the CPI 31 searches and reads the preset information stored and managed as described above, and operates the pan / tilt 200. By controlling, the photographing angle of the surveillance camera 100 is changed to a position corresponding to the first preset, the second preset, and the third preset, respectively, to sequentially perform a series of operations of photographing (S11). ).

In the case where the above-described series of operations are performed, when the temperature detection sensor is operated due to the occurrence of a fire to output a detection signal (S12), in the CPI 31, the detection signal is a plurality of detection sensors. It is checked whether they are simultaneously outputted from the devices (S13).

For example, when only the third temperature detection sensor (Sensor # 3) outputs a voltage of 6.5 V exceeding a 5 V voltage previously set as a reference voltage, and the other temperature detection sensor outputs a voltage less than 5 V, The CPI 31 determines that a fire has occurred at a position where the third temperature detection sensor is installed, and controls the pan / tilter 200 to operate the surveillance camera so that the surveillance camera performs a third preset (Preset # 3). It is possible to quickly photograph the position corresponding to (S14).

In addition, the CPI 31 operates and controls the OSD generator 34 to display an OSD image of a guide message indicating that a fire has occurred at a location where a third temperature detection sensor is installed, on a monitor screen. In addition, the HDR system 32 is controlled to record and store the video image photographed by the surveillance camera 100 on the hard disk 35.

On the other hand, when the detection signal is output from the plurality of sensors, for example, as shown in FIG. 5, the 6.5 V voltage is output from the third temperature detection sensor # 3 and the second temperature detection sensor ( When the 5.5V voltage is output from the sensor # 2, the CPI 31 compares the voltage values of the detection signal with each other and determines the priority in order of the magnitude of the voltage values. In this case, the first priority Priority_Order # 1 is determined at the third temperature detection sensor, and the second priority Priority_Order # 2 is determined at the second temperature detection sensor (S15).

In the CPI 31, the pan / tilter 200 is operated and controlled so that the surveillance camera first and rapidly photographs a position corresponding to the third preset (Preset # 3), and then, In order to capture the position corresponding to the second preset (Preset # 2) (S16), at this time, the operation of the OS generating unit 34, the third temperature detection sensor and the second temperature detection sensor in the installed position The OSD image of the guidance message indicating that a fire has occurred is superimposed on the monitor screen, and the HDR system 32 is operated to control the video image captured by the surveillance camera 100. The record will be saved to disk.

In addition, when an emergency situation release is requested by the manager (S17), the above-described monitoring operation is repeatedly performed, or any corresponding operation requested by the administrator, for example, operation control of the HDR system, An operation of reproducing and outputting a video image recorded on the hard disk is performed (S18).

On the other hand, in the CPI 31, an emergency situation occurs when the voltage values of the detection signals output from the respective temperature detection sensors are compared, and the deviation between the voltage values exceeds a predetermined reference value set in advance. After determining that the video signal is received, the priority of photographing the surveillance camera may be determined in an order corresponding to the magnitude of the voltage values of the detection signal.

For reference, the temperature detection sensor may be replaced by another type of detection sensor such as a gas detection sensor or the like, or may be mixed with other detection sensors.
