Description

A method for providing a spatial imaging system with improved drawing precision using drones and aerial surveying images {Providing method for spatial imaging system}

The present invention relates to a method of providing a spatial image drawing system that improves the precision of drawing using drones that quickly draw video images of features in the field of spatial image drawing technology and aerial surveying images, and more specifically, topographical features concentrated in downtown areas It is possible to draw the landmark images of various buildings, which are waters, according to the actual features and apply them to the exact location in the drawing image, but the cost of aerial photography is lower than that of aerial photography, which is expensive and has a long term. And it relates to a spatial imaging system that enables the completion of a drawing image that can guarantee reliability by quickly reflecting the changing topographical image image using a drone that is easy to shoot periodically in a short term.

In general, the drawing image used for making a numerical map is made as a simple image if possible in order to help the understanding of the user using the map and to minimize the visual objection.

For example, in the case of a device in which a user can quickly and easily check and understand a drawing image being output on a monitor, such as a navigation device, the background of the drawing image is inevitably different from the actual appearance.

(a) of FIG. 1 is a drawing image that has simplified topographic information as much as possible, and (b) is a drawing image showing the appearance of the actual terrain. The arrangement of B) can be easily and quickly understood by the user, but when comparing the corresponding drawing image with the topography in the actual field as in the case of FIG. ) and the features, users will feel confused about whether the actual site and the drawing image are identical.

In order to solve this problem, a system that can correct and update the drawing image has been developed. The spatial image drawing correction and update system installs a location measuring device on an actual feature on the site to check the image of the feature, and separately collects the coordinate values and location information of the location measuring device from the GPS, It can be said that the existing drawing image stored in the numerical map DB is updated by combining the image with the separately measured coordinate values and location information.

However, since the position measuring device used in the spatial image drawing correction and update system works in a state in which it is combined with the GPS at the site, it was common to be produced exclusively for the wilderness or relatively secluded outlying areas that are not obscured by various landforms. .

Therefore, in the city center where high-rise buildings are concentrated, it is difficult to communicate with GPS satellites, and numerous jammers are flooded. There was also a limit to installing a measuring instrument, and since aerial photography requires high cost, it is difficult to quickly reflect changes in topographical features because it cannot be taken periodically and repeatedly.

Furthermore, in aerial photography, since the aircraft passes the filming point at high speed, it is impossible to stay in the filming area, so if necessary, the aircraft must be turned and re-photographed every time. Have.

Then, a flight means to replace aerial photography using an aircraft is required. A means capable of taking low-cost, short-term periodic photographing and ensuring flight stability and precise photographing is required.

Since the side image may not appear properly when (200) is taken, the side image is acquired as a stereoscopic image and then synthesized with a planar image to convert the overall exterior image into a 3D stereoscopic image.

In the present invention, the RF transmitter (R1, R2, R3) oscillates RF so that the drone 200 can receive it, and the oscillated signal has a different frequency band for each RF transmitter (R1, R2, R3). Since the unique RF is included, the drone 200 will be able to identify the RF transmitters R1, R2, and R3 that oscillated the RF through the received RF.

Therefore, it can be calculated by the Pythagorean theorem.

In this way, based on the ground point directly below the drone 200 in the shooting zone, the coordinate values obtained by each GPS receiver (G1, G2, G3) and the distance information from the reference point to the RF transmitters (R1, R2, R3) are known. Therefore, in the end, the location information of the RF transmitters (R1, R2, R3) can be displayed on the video image of the photographed zone. becomes possible

In the present invention, the drone memory 217 performs a function of recording the photographed image synthesized with location information in the form of a storage and then transmitting it to the drawing module 330 according to the control signal of the drone controller 210 .

6A is an exemplary view showing the coupling relationship between the battery and the vibration-free unit according to the present invention, and FIG. 6B is an exemplary view showing the coupling relationship between the storage battery and the vibration-free unit according to the present invention.

On the other hand, the micro gas turbine generator 241 and the storage battery 270 are each provided with a plurality of lower legs at the lower portion thereof to be seated and coupled to the vibration-free unit 800, and the vibration-free unit 800 includes the engine chamber 230. It consists of at least two damping parts 500 fixedly installed on the inner lower surface or on the storage battery installation groove 250, and a fluid buffering part 600 inserted into the insertion space of the damping part.

Of course, in the reverse case, the vibration transmitted when the micro gas turbine generator 241 or the storage battery 270 is driven is blocked from being transmitted to the drone body 220 or the engine chamber 230, resulting in the drone 200. It contributes to securing a precise video image by maintaining stable operation during flight of the drone and maintaining a shake-free posture when shooting the camera 211 mounted on the bottom of the drone.

Hereinafter, the damping unit 500 and the fluid buffering unit 600, which are each component constituting the vibration-free unit 800, will be described in detail.

Figure 7a is a perspective view of the damping part according to an embodiment of the present invention, Figure 7b is a cross-sectional view of the damping part according to an embodiment of the present invention.

The damping unit 500 is formed on the inner lower surface of the engine chamber 230 or on the storage battery installation groove 250, the cylindrical damping case 510 in which the insertion space 511 is formed in the center, on the side of the damping case A plurality of damping holes 512 perforated in the transverse direction, a damping elastic part 520 that can be selectively inserted into the plurality of damping holes, respectively, and coupled to the side of the damping case to prevent the damping elastic part from being separated from the damping hole It is configured to include a damping lock (530).

The lower leg 271 of the storage battery 270 is introduced into the insertion space 511 to be fixedly coupled. It goes without saying that the lower leg of the miniature gas turbine generator 241 is similarly introduced into the insertion space 511 to be fixedly coupled. A rail 513 is installed on the inner upper end of the damping case 510 in the transverse direction, and a plurality of elastic rings 514 are slidably coupled to the rail 513 . The plurality of elastic rings 514 may be made of an elastic material, and may be contracted or expanded according to an applied impact.

The plurality of elastic rings 514 slide along the rail 513 when the fluid buffer unit 600 inserted into the insertion space 511 is strongly shaken back and forth, left and right, and collide with each other to apply the external applied to the fluid buffer unit 600 . It can perform the function of mitigating the impact. The plurality of damping holes 512 are formed in four directions in the front, rear, left, right, and right directions of the damping case 510 to form a set of four damping holes.

The four damping holes 512 constituting a set are stacked up and down, and the damping lock 530 is longitudinally coupled to cover these damping holes 512 . The damping lock 530 may be coupled with a conventional bolt or the like.

It may be configured to include a damping cover 523 coupled to the other end.

The damping elastic part 520 may be selectively inserted into the damping hole 512 or separated from the damping hole 512 . That is, the user can insert the damping elastic part 520 only into the desired damping hole among the 16 damping holes 512, and accordingly, the overall buffering force of the damping part 500 can be adjusted.

The damping insertion part 521 is made of a magnetic material such as metal, and since a permanent magnet 515 is coupled to the inner end of the damping hole 512, the damping elastic part 520 is attenuated when the damping hole 512 is inserted. The insertion part 521 may be naturally located at the inner end of the damping hole 512 .

The damping cover 523 is formed to have the same size as the size of the damping hole 512, and the damping lock unit 530 coupled in the longitudinal direction to the damping case 510 blocks the damping cover 523, thereby damping. The elastic part 520 does not separate from the damping hole 512 . As described above, in the present invention, when the fluid buffer unit 600, which will be described later, is inserted into the insertion space 511, the damping unit 500 surrounds the fluid buffer unit 600 from front to back, left and right, so that the fluid is buffered from external shocks or vibrations. It is possible to protect the unit 600 and the miniature gas turbine generator 241 or the storage battery 270 coupled thereto.

In addition, since the present invention can insert the damping elastic part 520 only into the desired damping hole among the plurality of damping holes 512 in consideration of the surrounding circumstances or the weight of each part, the user can freely adjust the buffering force according to the situation. There is an advantage that

8 is an exploded view of the fluid buffer according to an embodiment of the present invention.

The fluid supply unit 610 is formed in an empty cylindrical shape so that a fluid can be accommodated therein, and a fluid supply hole 611 is perforated to supply a fluid to the lower surface. The upper part of the fluid supply unit 610 The surface is made of a material having elastic force, such as rubber, and accordingly, when the lifting unit 700 coupled to the upper portion of the fluid supply unit 610 shakes up and down, the fluid inside comes out from the fluid supply hole 611 by pressure. .

The fluid upper plate 620 is disposed under the fluid supply unit 610, and the upper plate through hole 621 is perforated up and down on one side. The fluid upper plate 620 is formed in a disk shape, and the upper plate through hole 621 is formed at a position corresponding to the fluid supply hole 611 .

The fluid rotating plate 630 is disposed under the fluid upper plate 620, and a rotating through hole 631 is perforated vertically on one side. A hollow 633 is formed in the central portion of the fluid rotating plate 630 so that the fluid rotating plate is formed in a ring shape as a whole.

A ring-shaped rotary communication groove 632 communicating with the rotary through hole 631 is recessed in the upper surface of the fluid rotary plate 630 . Since the fluid rotating plate 630 is rotatable, the fluid transferred from the upper plate through-hole 621 to the lower side is transmitted directly down through the rotating through-hole 631 or through the rotating through-hole 631 through the rotating communication groove 632 . ) and then down.

The fluid lower plate 650 is disposed under the fluid rotating plate 630, and a lower plate through hole 651 is perforated up and down on one side. The lower fluid plate 650 is formed in a disk shape, and a ring-shaped lower plate communication groove 652 communicating with the lower plate through hole 651 is recessed in the upper surface of the fluid lower plate 650 . Since the fluid rotating plate 630 is rotatable, the fluid transferred to the lower part through the rotating through-hole 631 is transmitted directly down through the lower plate through-hole 651, or through the lower plate through-hole ( 651) and then down.

The fluid rotating part 640 is disposed inside the hollow 633 of the fluid rotating plate 630 and is coupled to the upper surface of the fluid lower plate 650 to rotate the fluid rotating plate 630 .

The fluid rotation motor 641 may be electrically connected to the central control unit 90 to operate, and as the fluid rotation motor 641 operates, the fluid rotation gear 642 rotates so that the fluid rotation plate 630 is connected to the fluid rotation unit. It can be rotated based on (640). The fluid accommodating part 660 is disposed under the fluid lower plate 650 and is formed in a cylindrical shape with an empty inside so that the fluid can be accommodated therein.

A fluid accommodating hole 661 is perforated to accommodate the fluid in the upper surface of the fluid accommodating part 660 . The fluid connection part 670 connects between the fluid receiving part 660 and the fluid supply part 610 . That is, the fluid supplied from the fluid supply unit 610 and transferred downward may be accommodated in the fluid receiving unit 660 and then transferred back to the fluid supply unit 610 through the fluid connection unit 670 .

A one-way valve 671 is coupled to the central portion of the fluid connection part 670 . In the one-way valve 671 , the lifting unit 700 and the information unit 300 coupled to the upper portion of the fluid supply unit 610 are shaken by an external impact, so that the fluid pressure inside the fluid supply unit 610 increases and the fluid is transferred downward. When it becomes, it is not transmitted through the fluid connection part 670 but is transmitted through the fluid upper plate 620 , the fluid rotating plate 630 and the fluid lower plate 650 .

In other words, the fluid is transferred from top to bottom through the fluid supply unit 610, the fluid upper plate 620, the fluid rotating plate 630, the fluid lower plate 650 and the fluid receiving part 660 as shown by the dotted line in the drawing. As such, in the present invention, since the fluid rotating plate 630 can be rotated by the fluid rotating unit 640, the moving distance of the fluid transferred from the fluid supplying unit 610 to the fluid receiving unit 660 can be varied depending on the situation. .

That is, as shown by way of example in the drawings, the rotation through hole 631 of the fluid rotating plate 630 is rotated (longest distance) to form 180 degrees with the upper plate through hole 621 and the lower plate through hole 651, The fluid supplied from the fluid supply unit 610 sequentially passes through the upper plate through hole 621, the rotary communication groove 632, the rotation through hole 631, the lower plate communication groove 652, and the lower plate through hole 651. It is accommodated in the receiving part (660).

Although not shown, when the rotation through hole 631 of the fluid rotating plate 630 is disposed on the same axis (shortest distance) to form 0 degrees with the upper plate through hole 621 and the lower plate through hole 651, the fluid supply unit ( The fluid supplied from the 610 sequentially passes through the upper plate through hole 621 , the rotational through hole 631 , and the lower plate through hole 651 and is received in the fluid receiving part 660 .

If, the rotation through hole 631 of the fluid rotating plate 630 is rotated (intermediate distance) to form an upper plate through hole 621 and a lower plate through hole 651 and more than 0 degrees and less than 180 degrees, the moving distance of the fluid is also in this changed according to

The frequency applied by external shock or vibration is in inverse proportion to the moving distance of the fluid. That is, in order to control the high-frequency vibration, the moving distance of the fluid must be set short, and in order to control the low-frequency vibration, the moving distance of the fluid must be set long.
