Description

A system applying a digital map information management method by comparing geographical information is proposed.

[0001] The present invention relates to a system to which a digital map information management method based on terrain information comparison is applied, and more particularly to a system to which a digital map information management method is applied, The present invention relates to a system to which a digital map information management method based on terrain information comparison capable of precisely managing a numerical value map by securing an accurate photographed image is provided.

Generally, a digital map based on three-dimensional image information is produced from images collected through aerial photography, and the collected images are completed with complete images through interconnections between neighboring images, Through this, a 3D image information digital map is completed and various GIS information is stored in the digital map.

However, the above-mentioned digital map production does not know the exact height and shape of the feature such as the building, and thus it is impossible to produce an accurate numerical map.

In this case, a worker directly dispatches a person to the site to perform a ground-level photographing operation through the camera, or an image-drawing system (see Korean Patent Application No. 10-2010-0091756, 2010.09.17, "), Which is used to acquire accurate information about the feature by capturing the feature image on the ground by putting the vehicle equipped with the vehicle directly on the field, thereby producing a more accurate numerical map.

However, in the case of the conventional ground photographing, birds and the like approach to the photographing equipment, and the photographing operation can not be performed smoothly.

In addition, in the case of the conventional ground photographing, since the feature is photographed from the ground, there is a limit to the photographing angle, and therefore, a precise image can not be obtained.

Therefore, it is possible to smoothly carry out shooting work without being disturbed from the surrounding environment, and it is necessary to check the change of the feature map and obtain a precise image of the captured image of the changed feature map, It is a fact that has been raised steadily.

Although a conventional digital map updating system based on comparison of existing geographic information and updated geographic information has been disclosed in Korean Patent Registration No. 10-1210543 (2012.12.10.), And the air can not be immediately charged when the air is blown out, so that a defect may occur.

10 to 14 are operation diagrams showing the operation of the present invention, and the operation of the present invention will be described with reference to FIGS. 10 to 14. FIG.

First, aerial photographing images are collected through aerial photographing using the aerial photographing apparatus 100.

The operator then compares the collected aerial photographic image with the existing aerial photographic image through the feature change detection device 300 to find the area where the change occurred.

Then, the operator moves the vehicle 210 so that the ground imaging device 200 is placed in the area where the change occurs.

At this time, the operator installs the first reflection mechanism (R1) and the second reflection mechanism (R2) in the ground photographing apparatus (200).

Subsequently, the operator injects air into the airship 230 through a separate air injection device (not shown), drives the driving devices 225c and 226c of the first and second winding devices 225 and 226, 225b, and 226b are released from the respective drums 225a2 and 226a2.

Then, the airship 230 is lifted as shown in FIG. 10, and the camera 242 of the photographing mechanism 240 photographs the feature B.

11, the sunlight is reflected to the surroundings and the birds or the like are prevented from approaching the ground-based photographing apparatus 200, whereby the photographing operation is smoothly performed . At this time, the first reflection mechanism (R1) and the second reflection mechanism (R2) are rotatable, and the reflection effect is maximized.

On the other hand, when photographing the feature B, when it is necessary to accurately photograph a certain portion of the feature B, when the airship 230 is positioned at the corresponding position as shown in FIG. 12, The driving devices 225c and 226c of the first and second fixing mechanisms 227 and 226 are stopped and the fixing hooks 227b and 228b of the first fixing mechanism 227 and the second fixing mechanism 228 are fixed to the airspeed (231) of the airbag (230) so that the airship (230) stays in a stable position.

At this time, the operator can adjust the elevation angle of the camera 242 through the driving device 243 of the photographing mechanism 240 and photograph the corresponding position precisely at various angles.

The operator then returns the camera 242 of the photographing mechanism 240 to the original position and then the first fixing mechanism 227 and the second fixing mechanism 228 and the airship 230 And the driving devices 225c and 226c of the first and second winding devices 225 and 226 are driven so that the wires 225b and 226b are continuously released and the airship 230 is moved upward.

On the other hand, when the camera 242 of the photographing mechanism 240 photographs the feature B along with the movement of the airship 230, the control unit 290 obtains the height information of the photographing position from the first ultrasonic device 261 And confirms to what degree the image is taken.

Also, the second ultrasonic device 262 of the device 260 measures the presence of the feature B by outputting ultrasonic waves as shown in FIG.

Therefore, when the airship 230 rises above the apex of the feature B, the second ultrasonic device 262 does not detect the feature B. At this time, the control unit 290 stops the driving of the driving devices 225c and 226c of the first and second winding devices 225 and 226 upon receiving the undetected signal from the second ultrasonic device 262.

At this time, the height data from the first ultrasonic device 261 of the device for height-measuring device 260 is stored as the height of the feature B.

14, the first movable body 222 and the second movable body 223 are moved as necessary so that the wires 225b of the first retracting device 225 and the wires 225b of the second retracting device 226 are moved, The airbag 230 can be stably fixed.

When the above photographing operation is completed, the operator returns the airship 290 to its original position and finishes the operation.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, it is possible to smoothly perform a ground photographing operation by preventing access to birds and the like from the surroundings.

Further, according to the present invention, an accurate image image of a feature item that can not be confirmed through aerial photographing is obtained, so that the feature map can be expressed precisely when performing a drawing operation, and the numerical map can be updated precisely.

Further, according to the present invention, the elevation angle of the camera 242 of the photographing mechanism 240 can be adjusted, so that the feature can be photographed even at a square angle, thereby obtaining a more precise image image, thereby making it possible to produce a precise digital map.

Further, according to the present invention, it is possible to acquire a video image of the feature item and to secure the height data of the feature item, so that a more precise numerical map can be produced or updated.

Further, since the ground photographing apparatus 200 has mobility, the present invention can quickly produce or update a digital map in the digital map maker 400 remote from the ground photographing apparatus 200.

15, the present invention provides a structure capable of stably lifting and lowering the airship 230 and air filling the airship 230 so as to prevent an emergency failure during use, thereby improving the accuracy and efficiency of image acquisition. .

A further embodiment according to the present invention will be described in more detail as follows.

As illustrated in FIG. 15, the airship 230 floats due to the air injection method, so that it floats in an irregular shape. Therefore, even if pulled out from both sides without a guide, it is difficult to fix it to a specific position. Moreover, it is even better if the wind blows.

In addition, there is a disadvantage that, when used for a long time, the air does not come out easily because of the air being blown out, and when the air is blown off during floating, it sinks.

Thus, in a further embodiment of the present invention, a multi-stage drawing rod (ROD) is further provided at the center of the upper surface of the imaging apparatus main body 221.

The multi-stage drawing rod (ROD) is a coaxial superposition structure in which a plurality of cylinders are superposed on each other and drawn out in a non-powered manner, and is formed into a generally known antenna type, more precisely, a telescopic type.

At the uppermost end, a latching piece (HAN) is fixed in a direction orthogonal thereto, and a through hole (HAL) is formed in the latching piece (HAN).

In particular, an air injection pump (PM) is installed on the upper surface of the latching piece (HAN). The air injection pump (PM) is a small pump and is means for supplying air.

An extension pipe CL extends to an output end of the air injection pump PM and is connected to an injection port 232 of the airship 230.

In addition, the bottom surface of the retaining piece HAN is coated with a highly viscous urethane resin and is excellent in adhesion when it comes in contact with the surface of the airship 230, that is, the airship 230 mainly formed of a synthetic resin tube, Therefore, the airship 230 can be closely adhered without slipping.

The airship 230 is provided with a pressure sensor SS and the pressure sensor SS is connected to a control box CB integrally provided at one side of the air injection pump PM.

At this time, the control box CB includes a controller and a battery for driving, and determines whether to operate the air injection pump PM according to the measured value of the pressure sensor SS.

For example, when the internal pressure falls below a predetermined level, the controller incorporated in the control box CB drives the air injection pump PM to inject air, and stops the internal air So as to prevent defects.

In addition, when the airship 230 is lifted up, the multi-stage withdrawing rods ROD are lifted up by the engaging pieces HAN that contact the airships 230, so that the airships 230 can not escape The airship 230 moves only on a predetermined route.

Of course, the pair of the multi-stage drawing rods ROD may be installed in front and rear.

At the lower ends of the supports 225a1 and 226a1 for fixing the drums 225a2 and 226a2, a multi-stage drawing cylinder CYR is connected through the movement bars 222a and 223a.

Since the support rods 225a1 and 226a1 can be lifted up to a certain height, the multi-stage drawing cylinder CYR can accurately control the height of the airship 230 up to a certain height.

In addition, the multi-stage drawing cylinder CYR is fixed to the upper surface of the vehicle 210.

As described above, the additional embodiment according to the present invention guides accurate launching of the airship 230 when the airship 230 floats, and more precisely control is possible up to a certain height, thereby enabling a more effective and efficient image capturing operation.
