The present invention relates to a preset setting method using a virtual map, for example, in a digital video recorder (DVR) to which a plurality of surveillance cameras are connected, for setting preset information for each surveillance camera. In this case, the present invention relates to a preset setting method using a virtual map for preventing a plurality of preset information from overlapping each other.

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 surveillance camera 100 may include a surveillance area by a panning operation rotated 360 degrees in the horizontal direction by the pan / tilt 200 and a tilting operation rotated 180 degrees in the vertical direction. Can be changed in the other direction.

In addition, in the surveillance camera, a 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.

Meanwhile, the digital video recorder 300 outputs and displays the video image photographed by the surveillance camera through a monitor screen and records and stores the hard disk (HDD) included in the device. For example, a user who monitors a corresponding area through the monitor screen may remotely adjust a pan / tilt angle of the pan / tilt 200 as illustrated in FIG. 2. When the photographing angle of the surveillance camera 100 reaches a desired specific angle, the surveillance camera 100 is set to a preset.

In addition, the pan / tilter 200 stores and manages a plurality of preset information that is arbitrarily set by the user as described above. In the preset information, as shown in FIG. Preset Number, Pan_Angle, and Tilt_Angle may be stored in a table.

In addition, when the user selects a predetermined preset number or performs an auto preset control operation, in the pan / tilt 200, for example, the surveillance camera 100 may be used. The shooting angle is set to the pan 0 degree and tilt 0 degree states set in the first preset (Preset # 1).

Then, when a predetermined time (for example, 5 seconds) elapses, a series of photographing angles of the surveillance camera 100 are set to 170 degrees of pan and 150 degrees of tilt of the second preset (Preset # 2). Since the preset control operation is performed sequentially, the surveillance area corresponding to each preset is taken in order.

Recently, however, many surveillance cameras have been connected to a single digital video recorder. For example, after installing a large number of surveillance cameras in a large space, a number of major surveillance areas are taken and monitored. In order to set a preset, the user must manually select and manually select an optimal surveillance camera for each surveillance region, and then input a pan / tilt / zoom value. There is a problem that the setting decreases the monitoring performance.

Therefore, the present invention was created to solve the above problems, for example, in a digital video recorder (DVR) connected with a plurality of surveillance cameras, preset information for each surveillance camera is stored. When setting, using a three-dimensional virtual map (Virtual Map), to provide a preset setting method using a virtual map so that a plurality of preset information does not overlap each other, the purpose is to.

Preset setting method using a virtual map according to the present invention for achieving the above object, the first step of displaying a three-dimensional virtual map image for selecting and specifying the pan / tilt angle of the camera; And if any one virtual map is selected from the displayed virtual map images, setting a pan / tilt angle corresponding to the virtual map as preset information of the corresponding camera.

In addition, if a virtual map previously set as preset information is duplicated among the virtual map images, displaying a corresponding guidance message or displaying the duplicated selected virtual map differently from other virtual maps; And storing the virtual map as preset information for the corresponding camera, and then controlling the preset operation of the corresponding camera using the pan / tilt angle applied to the virtual map.

Hereinafter, a preferred embodiment of a preset setting method using a virtual map according to the present invention will be described in detail with reference to the accompanying drawings.

First, in the preset setting method using the virtual map according to the present invention, as described above with reference to FIG. 1, the pan / tilt / zoom (Pan / Title) of the monitoring camera 100 mounted in the pan / tilt 200. / Zoom) to control the operation more efficiently, a plurality of surveillance cameras can be connected to the digital video recorder 300 to which the present invention is applied.

On the other hand, in the digital video recorder 300, as shown in Figure 3, when performing a preset setting operation in response to a user's request, a three-dimensional virtual map image, the user interface (User) Interface) is displayed as a menu screen, and the number of virtual maps shown in FIG. 3 can be variably increased or decreased by the size of the monitoring location.

In addition, each virtual map displayed on the virtual map image is given a unique virtual map number, for example, a user manipulates a shift key or a mouse to display various virtual map images. When the 56th virtual map is selected and specified among the virtual maps, the digital video recorder associates and stores the pan / tilt angle corresponding to the 56th virtual map as preset information of the corresponding camera.

For example, as shown in FIG. 4, when the user selects and designates a 56 th virtual map as preset information for the first camera, unique position information on which the first camera is installed and the 56 th virtual map are installed. The pan / tilt angle of the first camera is set to 15 degrees and 45 degrees by referring to and calculating the corresponding pan / tilt angle.

Accordingly, the user can more conveniently perform a preset setting operation for specifying a pan / tilt angle for each camera by using the three-dimensional virtual map image. For example, as shown in FIG. As described above, when the 56th virtual map set as the preset of the first camera is repeatedly designated as the preset of the second camera, the digital video recorder indicates that the 56th virtual map is previously set as the preset of the first camera. The guidance message may be displayed or the 56th virtual map may be displayed in a different color to distinguish it from other virtual maps.

Then, after setting the preset information for each camera through the above-described process, as shown in Figure 6, in the digital video recorder, the preset at the pan / tilt angle corresponding to the virtual map for each camera For example, when the 56th virtual map (VM = 56) is set as preset information with respect to the first camera CAM 1, any pan / tilt assigned to the 56th virtual map is performed. The angle is used to control the pan / tilt operation of the first camera.

In addition, when the 48th virtual map (VM = 48) is set as preset information with respect to the second camera CAM 2, by using an arbitrary pan / tilt angle given to the 48th virtual map, Since the preset operation is performed using a series of virtual maps controlling the pan / tilt operation, it is possible to efficiently prevent a plurality of preset information from overlapping each other.

As mentioned above, preferred embodiments of the present invention described above are disclosed for the purpose of illustration, and those skilled in the art can improve other various embodiments within the spirit and technical scope of the present invention disclosed in the appended claims below. Changes, substitutions or additions will be possible.

In the preset setting method using the virtual map according to the present invention as described above, for example, in a digital video recorder (DVR) to which a plurality of surveillance cameras are connected, the pan / tilt angle for each camera is selected and designated as preset information. Display a three-dimensional virtual map image, and if any one of the displayed virtual map images is selected, by setting the pan / tilt angle corresponding to the virtual map as preset information of the corresponding camera, It is a very useful invention to be able to conveniently set the preset information per star more efficiently, and also to prevent a plurality of preset information from overlapping each other in advance.
