Description

Numerical map error checking system based on the secured data}

The present invention relates to a numerical map error checking system based on data secured in the field of numerical map technology, and more specifically, to the original coordinate value of the ground reference point by stably performing the role of a reference point to duplicate the coordinate data of the numerical map It is possible to recognize the degree of error of the reference point by providing both the absolute coordinate information and the relative coordinate information of the ground reference point according to the change and comparing them. It is related to the numerical map error checking system.

In general, in order to express a ground object image expressed on a numerical map as a geometric element, point, line, and plane drawing elements are used.

Specifically, if we look at the case of expressing planes in a numerical map, various topographic features such as road boundary surfaces, buildings, actual width rivers, and water topographic boundary surfaces are expressed in surface form and displayed in color and pattern.

That is, in most cases, one surface-shaped object is used to express one feature, but there are cases where two or more surface-shaped objects are formed to express one feature.

Currently, most systems that edit or manage numerical maps express a surface shape with a polygon object.

In addition, a plurality of polygons to form a single object is called a multipolygon (MultiPolygon).

At this time, in the case of expressing the color of the polygon, the hole does not display the color. That is, it represents a perforated surface shape.

In the case of performing input and editing operations for producing a numerical map (DWG file) using the above-described method, polygons and multi-polygons can be expressed only as a closed-polyline with both endpoints connected.

These numerical maps are produced from images collected through aerial and ground photography, and the images collected in this way are completed as a complete image through interconnection between neighboring images and are produced as a numerical map.

However, in order to interconnect the images collected in this way, a standard for an accurate connection between the images is required.

That is, it is necessary to accurately perform aerial photography for each GPS coordinate and to collect an accurate aerial image image for each GPS coordinate.

However, an accurate numerical map can be produced only by providing accurate coordinates for the shooting point. If the coordinates of the ground reference point used for this purpose are changed due to changes in the terrain or the development environment, it was not possible to create an accurate numerical map by reflecting this. .

In addition, since aerial photography is performed at a high altitude, there is a limit to increasing the resolution with a camera equipped with a telephoto lens with limited magnification.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as limited to the embodiments described herein.

As shown in Figure 1, the system according to the present invention is mounted on a ground reference point 100 installed at a specific photographing location, an aircraft 200 used for aerial photography, and the aircraft 200, and a ground reference point 100. A numerical map maker 300 that communicates with and receives absolute coordinate information and relative coordinate information to check an error and at the same time produces a numerical map based on the video image taken by the aircraft 200, and the ground reference point 100 and It includes a satellite (GPS) that communicates and provides relative coordinate information.

At this time, the ground reference point 100 is capable of wireless communication as shown in FIG. 2 , and may be designed to respond only in response to a specific signal transmitted within a communication distance with the aircraft 200 .

That is, the aircraft 200 is configured to transmit coordinate information possessed by the ground reference point 100 to the aircraft 200 in response to a specific signal transmitted by the aircraft 200, and when there are a plurality of ground reference points 100, a unique number is assigned to each They are constructed so that they can be distinguished from each other by receiving.

Here, the ground reference point 100 includes a fixed housing 110 fixed to the reference point installation floor, a generator 120 built into the fixed housing 110, and a storage battery 130 connected to the generator 120 . and a housing door 140 that is formed on a part of the outer peripheral surface of the fixed housing 110 and can be opened and closed, a reference point controller 150 installed on the inner surface of the housing door 140 and including a memory, and the fixed housing ( A spherical rotating shaft ball 160 fixed to the upper end of 110) and partially open, a pair of hemispheres 170 fitted on the rotating shaft ball 160, and each hemisphere 170 A wing plate 180 fixed integrally, a generator shaft 122 fixed to the insertion end 172 of the hemisphere 170, and a wireless communication antenna connected to a wireless communication module mounted on the reference point controller 150 ( 190).

At this time, the rotation shaft ball 160 is a kind of spherical rotation shaft. The reason for doing this is to ensure that the rotational degree of freedom is very free for 360°, so that it can be rotated well even in a small wind.

In addition, an opening 162 having a predetermined radius is formed at the upper apex of the rotating shaft ball 160 , and a pair of hemispheres 170 are seated on the outer periphery.

Here, the hemisphere 170 is a member formed in a hemispherical shape and becomes a rotating body that rotates using the rotating shaft ball 160 as a rotation axis while being fitted in the rotating shaft ball 160 .

In this case, the insertion end 172 is formed at one end of the hemisphere 170 to face each other, and the wing plate 180 is integrally formed at the other end.

Then, the insertion end 172 of the hemisphere 170 is fixed to the generator shaft 122 after being fitted into the opening 162 formed at the upper end of the rotating shaft ball 160 .

In particular, the wing plate 180 has lattice grooves 182 formed on both sides thereof so that it can easily and largely receive resistance to wind.

In addition, the moisture absorption foam 132 is fixed to the lower portion of the storage battery 130 to absorb moisture generated therein, and the housing door 140 can be opened and replaced if necessary.

With such a structure, self-charging is possible, enabling semi-permanent use without drawing commercial electricity.

In particular, the reference point controller 150 is configured to transmit the absolute position value it has as a response signal in response to a specific signal sent by the aircraft 200 .

On the other hand, the numerical map making machine 300 includes a plurality of processing modules (M) for big data processing, as in the example of FIG. 3 , and the processing modules (M) are equipped with a main board (B), all of which are enclosed 310 has a built-in structure. Therefore, it is necessary to implement an efficient cooling means for the processing modules (M).

To this end, in the present invention, it is possible to have a structure to cool the main board (B) in order to prevent deterioration of such a plurality of processing modules (M) to increase durability and to maintain a longer lifespan of the digital map making machine (300). Since the board (B) is in the form of a PCB that processes electronic signals, most are cooled using a fan. However, in the case of using a fan, a lot of dust is trapped in the fan in a short time, so there is a disadvantage that the cooling efficiency is lowered, and a short circuit may occur due to the dust.

In addition, in the present invention, since soldered marks remain on the back side of the main board (B) in the form of a PCB, there is a possibility of a short circuit when the cooling plate is faced. By fixing (CH), the cooling air flowing inside the cooling chamber (CH) is continuously circulated by the cooler 1500 and the air circulation fan 1510 to indirectly cool the main board (B).

At this time, the inter rod SA is a member having an insulating function, sealing property and heat dissipation property, and is closely provided in a rectangular frame shape along the edge.

Therefore, since the liver rod (SA) has to perform an important function, it is not simply composed of a general silicone resin, but must be prepared in a specially combined composition. To this end, in the present invention, 10% by weight of XanthanGum, It is composed of 10% by weight of the pin, 10% by weight of copper powder, 10% by weight of polysiloxane, 10% by weight of aluminum oxide powder, 5% by weight of graphite powder, 20% by weight of ethyl acetate and the rest of the acrylic resin.

At this time, xanthan gum is very useful as a component of the acrylic heat-dissipating adhesive of the present invention because it has excellent transparency and light transmittance, and has a low viscosity and does not need to be dissolved in a separate solvent. In addition, triphenylphosphine is added to promote curing and stabilize curing of the pressure-sensitive adhesive.

In addition, copper powder has excellent malleability and ductility, and has excellent electrical conductivity as well as thermal conductivity. In addition, polysiloxane is added to prevent cracks or drop-offs by suppressing an increase in hardness after curing of the pressure-sensitive adhesive to maintain elongation.

In addition, aluminum oxide powder is added to improve heat dissipation properties by implementing thermally conductive filler properties while maintaining the formability after adhesion of the pressure-sensitive adhesive. In addition, ethyl acetate is usually used as a diluent or solvent for paints, but in the present invention, as a dispersion stabilizer, uniform dispersion induction and anti-agglomeration are used to prevent deterioration of heat dissipation properties due to agglomeration or micro-dispersion of a large number of powders in the process of dispersion. added for

And, the acrylic resin has a low specific gravity and high adhesive properties while maintaining colorless transparency, so it is the most suitable base resin as an adhesive according to the present invention.

On the other hand, the cooler 1500 is a small thermoelectric element (TEM), and is configured to generate cooled cooling air by allowing the cooling air to contact only the heat absorbing side.

In addition, the cooling air is configured to be smoothly circulated by the air circulation fan (1510).

In other words, the digital map maker 300 has a main board B on which a plurality of processing modules M are mounted, a main board SA in close contact along a rim on the back side, and a main board under the interposition of the gap SA. A cooling chamber (CH) fixed to the rear surface of (B) and a circulation pipe 1520 for continuously supplying cooling air to the cooling chamber (CH), wherein the circulation pipe 1520 has a cooler 1500 and , an air circulation fan 1510 for circulating the cooled air is further installed.

Accordingly, it is possible to stably cool the main board (B) so that the system can be stabilized as well as the efficiency of the system can be maintained.

In particular, in the present invention, as in the example of FIG. 4 , since the numerical mapping machine 300 has the shape of the housing 310 , the main causes of deterioration of the processing modules M are moisture and dust (dust), so it can be periodically removed. A vacuum processor 1600 is further installed on one side of the housing 310 so as to be there.

The vacuum processor 1600 can also improve the cooling efficiency through the cooler 1500 by maintaining the inside of the housing 310 at the same level as atmospheric pressure or slightly lower than atmospheric pressure.

The vacuum processor 1600 includes a cylindrical vacuum chamber 1610 . The vacuum chamber 1610 includes a plurality of connection pipe portions 1620 so as to be in communication with the inside while being sealed through one side of the housing 310 .

In addition, a discharge pipe 1630 is provided at one end of the vacuum chamber 1610, a solenoid valve 1640 is installed on the discharge pipe 1630, and a valve controller 1650 is installed in the solenoid valve 1640.

At this time, although not shown, the valve controller 1650 may be connected to and controlled with the above-described controller (not shown). Alternatively, it may be controlled by connecting a separate computer. In this case, the vacuum processor 1600 is not always operated, but is periodically attached and detached and used.

In particular, a moisture absorber 1660 is installed at the end of the exhaust pipe 1630 , and an exhaust port 1662 is installed in the center of the outer surface of the moisture absorber 1660 after moisture absorption and dust are collected through the moisture absorber 1660 . Only purified air is discharged into the atmosphere.

In this case, the moisture absorber 1660 is configured to be replaceable in a cylindrical shape.

In addition, a vent hole 1652 is formed in the valve controller 1650 to vent in the event of a sudden overload or to induce air intake through the vent hole 1652 to induce rapid facility stabilization.

In addition, a tube body 1612 communicating with the inside is fixed to a part of the outer peripheral surface of the vacuum chamber 1610, a vacuum detection sensor 1670 is installed in the tube body 1612, and the vacuum detection sensor 1670 is a controller and connected

Here, the vacuum detection sensor 1670 preferably uses a digital vacuum sensor, and a digitized numerical value of the vacuum degree inside the vacuum chamber 1610 can be measured.

Accordingly, the controller can continuously check and manage the degree of vacuum inside the housing 310 .

By configuring in this way, it is possible not only to secure cooling efficiency, but also to keep the inside of the housing 310 in a clean state, thereby optimizing the drive environment of the mounted processing modules (M).

On the other hand, in the present invention, the optical structure of the camera (CAM) is improved to increase the photographing efficiency.

To this end, as shown in FIG. 5 , the camera (CAM) according to the present invention includes a body housing 1200 having an optical system implemented therein, an imaging unit 1210 exposed to an upper portion of the body housing 1200, and the A telephoto lens 1220 exposed to a lower portion of the body housing 1200 is included.

At this time, the imaging unit 1210 is a means for storing a digital image, and the telephoto lens 1220 is a lens that can be adjusted to various magnifications so as to take a close-up photograph of a feature.

Here, since aerial photographing according to the present invention is photographed by the aircraft 200 at a high altitude, only the magnification of the telephoto lens 1220 is limited. Therefore, in addition to this, it is necessary to implement so that high magnification and ultra-high magnification can be adjusted, and the present invention implements this.

To this end, a first beam split 1230 is installed directly above the telephoto lens 1220, and a first reflection mirror 1240 is installed in parallel with the first beam split 1230 at an interval, and the second A first magnification lens 1250 is installed directly above the 1 beam split 1230, and a second magnification lens 1260 is installed directly above the first reflection mirror 1240, and the first and second magnifications are provided. A second beam split 1280 is completely divided between the lenses 1250 and 1260 by a partition wall 1270, and is disposed directly above the first magnification lens 1250 to coincide with the immediately below of the imaging unit 1210. is installed, a second reflection mirror 1290 is installed directly above the second magnification lens 1260, and a sliding guide SLG is installed on the upper end of the partition wall 1270, and the sliding guide SLG. is provided with a slider SL that selectively opens the first and second magnification lenses 1250 and 1260 while sliding along it, and the slider SL is toothed and moved with a gear GR driven by a motor. configured to be able to

Thus, it is possible to increase the magnification that can be raised by the telephoto lens 1220 alone. At least two high magnifications, that is, a high magnification and an ultra-high magnification can be further utilized, so that even detailed features can be captured.

For example, if the telephoto lens 1220 has a high magnification, for example, the first magnification lens 1250 , the slider SL blocks the beam flow to the second magnification lens 1260 and the beam to the first magnification lens 1250 . Only the flow is in an open state, which is controllable by moving the gear GR by controlling the driving of the motor by a controller (not shown).

Then, the subject is imaged in the order of the telephoto lens 1220 → the first beam split 1230 → the first magnification lens 1250 → the second beam split 1280 → the imaging unit 1210 .

On the other hand, in the case of passing through the second magnification lens 1260, which is an ultra-high magnification, the slider SL opens the beam flow to the second magnification lens 1260 and blocks only the beam flow to the first magnification lens 1250. This is controllable by controlling the driving of the motor by a controller (not shown) to move the gear GR.

Then, the subject is the telephoto lens (1220) → the first beam split (1230) → the first reflection mirror (1240) → the second magnification lens (1260) → the second reflection mirror (1290) → the second beam split (1280) → Images are captured in the order of the imaging unit 1210 .

After all, according to the present invention, it is possible to combine two high magnifications (high magnification, ultra-high magnification) in spite of a very narrow space, so that it is easy to control various magnifications, and a clearer image can be obtained.

In addition, in the present invention, as shown in the example of FIG. 6 , when the wireless communication antenna 190 is connected to a wireless communication module (not shown) to enable signal transmission, it is better to configure as shown in the figure to increase reception sensitivity.

That is, a module connection port 1910 is connected to the wireless communication module built in the reference point controller 150 , and a connection terminal 1920 is provided at an upper end of the module connection port 1910 .

In addition, the module connector 1910 is assembled in such a way that the antenna connector 1930 is inserted.

At this time, when the antenna connection port 1930 is connected, first, an insulating rod 1940 in which a silicone resin and ceramic are mixed and molded in a weight ratio of 2:1 is inserted into the connection terminal 1920, and the insulating rod 1940 is connected to An insertion hole 1940a having a diameter corresponding to that of the terminal 1920, and a loss attenuation hole 1940b extending the same length from the insertion hole 1940a and enlarged to have twice the diameter are formed.

In this loss attenuation hole 1940b, cable resistance loss occurs when the connection terminal 1920 is connected to the signal terminal 1950 of the antenna connection port 1930, and the insulating rod 1940 has a dielectric constant of 3-4. This will reduce the resistance loss. At this time, the length and size of the loss attenuation hole 1940b are designed to reduce the maximum loss by calculating the attenuation rate. That is, the resistance of about 25 ohms could be reduced as a result of the test when it had the same length as the insertion hole 1940a and had twice the diameter.

In addition, an insulating rod insertion groove 1960 is formed inside the antenna connection port 1930 for assembly, and a signal guide line 954 connected to the wireless communication antenna 990 is bound to the antenna fixing end 1970 .

In this way, it is possible to further increase the transmission/reception sensitivity of the wireless communication antenna 990 .
