The automatic mapping process of the CCTV information based on the spatial information according to the embodiment of the present invention has been described in detail. Hereinafter, specific examples implemented in accordance with the embodiments of the present invention will be described.

Example

It is possible to collect the specification information of the corresponding CCTV in order to display each CCTV installed in the geographical position on the electronic map. The specification information may be acquired by field survey of each area, or may be directly received from each CCTV. Examples of the CCTV specification information include installation location (e.g., longitude and latitude), installation purpose, manufacturer, model name, address, monitoring direction, monitoring distance, angle of view and the like.

The surveillance zone data can be calculated according to the embodiment of the present invention based on the collected information. For example, as an item for displaying a surveillance area on an electronic map, a position, a surveillance direction, a surveillance distance, a maximum surveillance distance, a wide view angle range, a telephoto view angle range, It can be changed.

Then, a file in a format such as SHP, KML, or the like may be generated and the monitoring area may be mapped on the electronic map from each of the items.

Then, the appropriateness of the installation can be evaluated by GIS analysis of the density on the electronic map where each CCTV is installed and the redundancy of the monitoring range. According to the above evaluation, the CCTV may be newly installed, the installation position may be changed, or unnecessary CCTV may be removed. In this way, when the installation information of the CCTV is changed, the specification information and the installation information of the changed CCTV are updated in the database through the update of the specification information.

Meanwhile, in the above description, the step of automatically calculating each item for displaying the surveillance region and converting it into a DB can be realized as shown in FIG.

4 is a flowchart showing an example of calculating various attribute data according to an embodiment of the present invention.

Referring to FIG. 4, CCTV data is loaded by receiving a file (e.g., an excel file) in which collected CCTV specifications are arranged. Then, the user inputs the required specification values for each item to be displayed.

Then, set the geometry type to match the characteristics of each item. For example, as shown in FIG. 4, the position information can be set in the form of multipoint, the monitoring direction can be set in the form of a line, and the monitoring distance (or the maximum monitoring distance) For example, a wide angle mode or a telephoto mode, etc.) can be set in the form of a polygon.

Next, a unique number (FID) for the attribute values of the database may be defined, and the FID may be concatenated to match the data of each item according to the CCTV position.

Next, attribute data of each element may be input or required attribute data may be calculated from the inputted specification value. For example, information such as a CCTV name, a CCTV manufacturer, a CCTV model name, an address, and a URL (Uniform Resource Location) can be automatically extracted for a FID set for specific location information and converted into a database. In addition, the geometric data for the surveillance direction can be calculated and stored in the form of a line. In addition, the monitoring distance (or the maximum monitoring distance) or the photographing mode (for example, the wide angle mode or the telephoto mode, etc.) may be calculated and stored in the form of a polygon.

In this manner, the items calculated and stored in the database can be output as SHP files or the like.

As described above, the type of each item and the information to be stored in the database for the surveillance area to be displayed on the electronic map can be expressed as shown in Table 1 below.

As described above, each item for making a GIS DB can be classified into four types, for example. That is, as shown in Table 1, there are a 'Location' indicating a location where the CCTV is installed, a 'Direction' indicating a direction in which the CCTV is monitored, a 'Monitoring distance' Wide Mode "or" Tele Mode "indicating a range that can be confirmed through the angle of view of the CCTV, and the like.

For 'location', you can define the file name and then retrieve the longitude and latitude data from the specification information. In the case of the CCTV location, the geometric type can be defined as multipoint as described above, and the coordinates of the CCTV can be represented by the point data.

In addition, a unique number (FID) for attribute values received from the information for classifying the database is defined. In order to provide various information of CCTV together with location information, CCTV classification, manufacturer, model name, installation place, and URL information are retrieved and stored in DB.

In the case of 'Surveillance direction', after defining the file name, the assumed azimuth (angle measured in the clockwise direction with respect to the north or arbitrary direction of the planar rectangular coordinate system) is taken from the specification information. At this time, since the direction is represented by a line along the direction angle from the starting point of the CCTV position, the geometric type can be set as a line. In case of FID, it should be matched according to the attribute data based on the location information, so it is connected with the FID of the location information. If the CCTV is a Pan-tilt-zoom (PTZ) camera, the main monitoring direction is not present, so the attribute information is calculated only for a fixed camera.

The fixed camera calculates the end point (coordinate) of the line representing the viewing direction based on the CCTV position coordinate. At this time, the coordinates to be calculated are calculated by the direction angle, the position coordinates connected to the FID, and the maximum monitoring distance. The calculated value and position coordinates are data that can define the monitoring direction and are stored in the GIS DB.

In case of 'Surveillance distance' or 'Maximum surveillance distance', after defining the file name, the distance information (or maximum distance) that the CCTV can monitor from the specification information is obtained. At this time, the monitoring distance can be defined as a maximum distance at which the license plate can be recognized. In addition, since the monitoring distance is represented by a circular buffer with a monitoring distance (or a maximum monitoring distance) as a radius around the CCTV position, the geometric type can be set to 'polygon'. The FID can be connected to the position data as described above. The data coordinates of the circle (circumference-0 ~ 2Π) can be calculated with the monitoring distance (or the maximum monitoring distance) as the radius and the position coordinates connected with the FID as the center point. like this. The calculated data is a value that can define the monitoring distance or the maximum monitoring distance and is stored in the GIS DB.

In the case of 'Wide mode' or 'Tele mode', the file name is defined, and angle angle data of CCTV in wide angle mode or telephoto mode is received from the specification information. A wide angle lens (Zoom out) in the wide angle mode, and a zoom lens (Zoom in) in the telephoto mode. In addition, since the angle of view at this time is displayed on a two-dimensional map, only information on the horizontal angle is needed.

Since the surveillance range can be displayed in a fan shape having an angle of view at an angle around the CCTV position, the geometric type can be set as a 'polygon'. The FID is associated with the location data as described above. The fiducial data coordinates are calculated by using the coordinates of the position connected to the FID as the center point, setting the monitoring distance (or the maximum monitoring distance) as the radius, and defining the angle of view as an angle. The calculated data is stored in the GIS DB as a value that can define the surveillance range in the wide angle mode or the telephoto mode.

Hereinafter, an example of a method of geometrically displaying the surveillance region of the CCTV using the calculated attribute data for each item will be described with reference to FIGS. 5 to 12. FIG.

5 is a diagram showing an example of a surveillance direction display method according to an embodiment of the present invention. Referring to FIG. 5, coordinates for drawing a line expressing a surveillance direction are represented by x ₁ , y ₁ , a maximum monitoring distance L ₂ , a surveillance direction angle θ, another end point coordinate x ₂ , y ₂ , it can be calculated by the following equations (1) and (2).

The direction of the CCTV monitors, as shown in FIG. By connecting the x _2, y ₂ and CCTV position of x _1, y ₁ is computed in the 5 can be represented by a line.

6 is a diagram showing an example of a monitoring distance display method according to an embodiment of the present invention. 6, coordinates for drawing a circle expressing the monitoring distance (or the maximum monitoring distance) include CCTV position coordinates x ₁ , y ₁ , monitoring distance (or maximum monitoring distance) L ₂ , coordinates Hear x ₂ ... x _n , y ₂ ... y _n , it can be calculated by the following equations (3) and (4).

As shown in FIG. 6, by dividing 0 to 2? Into n equations, n coordinates constituting the circumference can be obtained through Equation (3) and Equation (4) .

7 is a diagram showing an example of a surveillance range display method according to an embodiment of the present invention.

Coordinates for drawing a sector representing the angle of view and the surveillance range of the wide angle mode or telephoto mode can be obtained by setting the CCTV position coordinate x ₁ , y ₁ , the monitoring distance (when in wide angle mode) or the maximum monitoring distance (in telephoto mode) to L ₂ , The viewing direction angle is θ, the view angle is α, the coordinates constituting the sector are x ₂ ... x _n , y ₂ ... y _n , it can be calculated by the following equations (5) and (6).

In this manner, when the angle of view is divided into n equally about the monitoring direction angle and n coordinates forming the arc are obtained through Equation (5) and Equation (6) The surveillance range can be displayed as a sector as shown.

On the other hand, for simple visualization, the representation is a sector, but the actual range (horizontal distance) that can be detected by the image is the shape of the straight line, not the arc, so the database stores the straight distance, not the arc length.

In the case of arcs, it is drawn based on the monitoring distance, but the distance that can be clearly monitored is shown, but it may not be clear in practice. This is because the photographed image covers more than the displayed range.

Therefore, in order to calculate the actual monitoring range, the monitoring distance or the maximum monitoring distance is L ₂ , the angle of view is α, and the monitoring range is L ₁ .

When the focal length of the camera is f and the size (horizontal) of the image is H, a method of verifying the above can be calculated as Equation (8) and Equation (9) below.

At this time, it can be confirmed that the error range of the calculated two monitoring ranges (L ₁ ) results is about 0.3 to 0.4 m.

Fig. 8 shows a calculation method of an actual monitoring range, and Fig. 9 shows a verification method of an actual monitoring range.

Thus, finally, the result as shown in Fig. 10 can be displayed.

10, the position 1, the surveillance direction 2, the surveillance distance 3, the maximum surveillance distance 4, the wide angle view angle range 5, The information of the telephoto angle range 6 can be displayed.

Meanwhile, according to another embodiment of the present invention, in order to evaluate the redundancy of the CCTV installation position, the total monitorable area can be calculated according to the monitoring direction and angle of view. Then, redundancy can be evaluated by checking the overlapping area when displaying multiple CCTV data.

The redundancy evaluation layer may be a monitoring area in the wide-angle mode and all the areas included in the monitoring range in the telephoto mode. When visualized, the redundancy evaluation layer can be displayed as shown in FIG.

At this time, although the area that can be monitored by the CCTV can actually be monitored more than the area calculated above, the distance that can be recognized by the user (for example, the distance at which the license plate can be recognized) In this case, the area of the surveillance area can also be defined as shown in FIG.

For example, as shown in FIG. 11, a CCTV monitorable range is confirmed by a redundancy layer defined by a pentagon, and an overlapping area between the CCTVs is calculated as shown in FIG. 12, can do.

13 to 16 are views showing the results of displaying each CCTV specification on an actual electronic map by a method of displaying each CCTV specification as described above.
