FIG. 1 is a flowchart illustrating a method of selecting a ccive installation point using a geographic information system according to the present invention. FIG. 2 is a diagram showing a step included in the selection method on a map. FIG. FIG. 4 is a diagram showing another step included in the selection method on a map, FIG. 5 is a diagram showing a position selected by the selection method on a map Fig.

Referring to FIGS. 1 to 5, a method of selecting a location for installation of a ccive using a geographic information system according to the present invention includes: (S10) confirming a location required for selection of a ccive; (S30) of calculating a predetermined radial area around the positions, a step (S40) of overlapping the predetermined radial area with respect to the positions (S40), and a step (S50) of calculating the density of the weight, and displaying the position information corresponding to the calculated density on a map (S60).

For example, the location of the selection of the ccive should include, for example, a location 10-1 for educational facilities for a child or a teenager, a location 10-2 for a life protection subject, a location 5-3 for a crime scene 10-3, A complaint request position (10-4), and the like.

In the case of the education facility location 10-1, installation of a ccive is required to protect children and adolescents, and the livelihood protection residence location 10-2 includes a living alone elderly person living alone, Installation is required to protect the buddies.

In addition, in the case of the five crime locations (10-3), five crimes such as murder, robbery, sex crime, violence, and theft occurred. As a result, the crime scene can be photographed It is aimed at preventing a crime in a certain way.

Here, predetermined positive (+) weights are assigned to, for example, the education facility location 10-1, the welfare recipient residence location 10-2, the five crime occurrence locations 10-3, and the like.

The weight is determined according to the degree of need for installation of the ccive, and in the case of the five crime occurrence locations 10-3, a higher positive weight can be given to a location where a more serious crime occurs.

Meanwhile, it includes a step S15 of confirming a selection unnecessary position together with the selection position of the ccive.

The selection unnecessary position may be, for example, a police or earth position 10-5, a streetlight or security position 10-6, an existing ccive installation position 10-7, and the like.

In the case of the police station or the earthquake location (10-5), the police station or the earthquake itself has an effect of preventing the occurrence of crime to some extent, and the position (10-6) such as the streetlight or security is kept bright even at night. This is due to statistical reasons that are somewhat lower than in the region.

A predetermined negative weight is assigned to the selection unnecessary position.

In addition, a minus weight can be applied by dividing the distance on the road centered on the police station or the earth station, that is, the distance on the road from the police station or the earth station, by predetermined ranges.

In this case, a minus weight value of a smaller absolute value is applied to a distance on a more distant road centered on the police station or an earth station, and a minus weight value of a larger absolute value is applied to a distance on a closer road.

As described above, the weight is applied to a predetermined radius area on the map, while confirming the installation location and the selection unnecessary position of the ccive and assigning the weight.

That is, for example, since the visible distance of the ccivi is about 80 m, the weight distribution area is set as the weight distribution area applied to the 80 m radial area centering on the ccvip necessary position and unnecessary position.

Then, it can be calculated and displayed on the map 20 as a region having a constant weight density as a result of overlapping of the positive weight and the negative weight with respect to the specific position.

At this time, a region having a higher weight density and a region having a lower weight density with respect to the calculated density can be classified on a map and displayed on a map.

That is, as shown in FIG. 3, the area having the highest weight class is displayed in red on the map 22, and the area having the lower weight density is displayed in blue or yellow on the map 24 Can be displayed.

For example, if the region having the highest weight class is referred to as a first class region and the region having the next highest weight class is defined as a second class region, Can be displayed on the screen.

In addition, by superimposing the map 40, which is displayed by a certain radius with respect to the point where installation of the ccive is absolutely unfavorable, and the map 30 combining the first-rank region and the second-rank region, The map can be represented by the map 60 of FIG. 3 by displaying on the combined map 30 the aerial photograph 50 excluding the point at which the installation of the above-mentioned cc is unnecessary.

In the aerial photograph 60 shown above, the area indicated by red color is the first grade area, and the area indicated by blue is the area where the existing ccive is installed.

However, in the above-described aerial photograph 60, the land use form of the first grade area indicated in red, or the empty space 64 or the apartment area 66 is excluded as a ccive installation exclusion zone.

In the case of the vacant space 64, it is very uncommon for people to travel in the first place. In the case of the apartment area 66, the bright state is maintained at night due to the streetlight or the security lamp installed in the complex, Because.

The points selected as the installation areas of the cisco through the above process can be displayed on the map 70 by being divided into green colors as shown in FIG.

While the present invention has been described with reference to the exemplary embodiments and the drawings, it is to be understood that the technical scope of the present invention is not limited to these embodiments and various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. Various modifications and variations may be made without departing from the scope of the appended claims.
