Description

A spatial image-drawing system that changes the geographic information}

The present invention relates to an image processing system of terrain information image image including GPS information in the field of image processing technology. It can be applied to the exact location in the topographical image image, but instead of aerial photography using a long and expensive aerial shooting term, it is possible to use a drone that can be periodically and inexpensively used to take a video image of a feature that is changed frequently. Secured and reflected quickly to complete reliable terrain information image image, and in particular, it is convenient to mount the image signal processing modules constituting the management server for image processing to prevent deterioration from heat generation to achieve long life and to prevent processing errors in advance. Terrain that contains GPS information It relates to an image processing system of the beam images.

In general, the topographical image image used for digital map production is produced as simple image image as possible to help the user of the electronic map and to minimize the visual rejection.

Particularly, in the case of a device that requires a user to easily and quickly identify and understand the terrain information image image output on the monitor, such as a navigation, the background of the terrain information image image may be significantly different from the actual appearance.

As can be seen through Figure 1, in the case of (a), the road state of the terrain and the layout of the terrain image (B) can be easily and quickly understood by the user, the terrain information image image in the actual site When comparing the terrain with the terrain, the user may feel confused about whether the actual site and the terrain information video image are identical due to the appearance of the terrain image (B, B ') and the terrain.

In order to solve such a problem, a system has been developed that can modify and update the terrain image image.

This system checks the image of the feature by installing the positioner on the actual feature of the site, and collects the coordinate value and the position information of the positioner separately from the GPS, and the image processing system measures it separately from the image of the identified feature. Coordinate values and location information are combined with each other to update the existing terrain information image image stored in the digital map DB.

By the way, the position measuring device used in this system is in the field combined with the GPS (PS), so the work proceeds, it was made for the wilderness or relatively secluded outland by the unobstructed by various terrain.

Therefore, it is difficult to communicate with GPS satellites in urban centers where high-rise buildings are concentrated, and numerous jammers overflow, and accurate positioning of terrain is impossible in urban areas where various malfunctions of various sensors occur.

In addition, there is a limit to the installation of a position measuring device in every building.

In addition, aerial photography is expensive, and thus it is difficult to periodically and repeatedly photographed, so it is difficult to quickly reflect the shape characteristics of the feature that changes frequently.

In addition, aerial photography is limited to the hassle of having to stay in the shooting area because the aircraft passes through the shooting spot at high speeds, causing the need for turning the aircraft and re-taking each time if necessary, resulting in significant waste of time and money. Have.

However, this is not intended to limit the embodiments in accordance with the concept of the present invention to a particular disclosed form, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

As shown in FIG. 2, the image processing system of the terrain information image image including the GPS information according to the present invention has an RF transmitter (R1, R2, R3) and a GPS receiver (G1, G2, G3) to perform a coordinate reference point function. At least three movable vehicles (100, 102, 104) mounted thereon; The RF signals R1, R2, and R3 are identified through the RF signals received from the RF transmitters R1, R2, and R3, and the coordinate information received from the GPS receivers G1, G2, and G3 is adjusted to the photographing zone. A drone 200 generating a captured image coded for each transmitter R1, R2, and R3; And a management server 300 having an image processing module 330 which receives the photographed image generated by the drone 200 and performs image processing.

At this time, the vehicle (100, 102, 104), as shown in the example of Figure 3, includes a vehicle controller 110 is mounted with a memory, RF transmitter (R1, R2, which transmits RF in accordance with the control signal of the vehicle controller 110, One R2) is installed in each vehicle.

In addition, each of the vehicles (100, 102, 104) is also provided with a GPS receiver (G1, G2, G3) to check the position information, that is, coordinate information by communicating with the satellite under the control signal of the vehicle controller (110).

In addition, a vehicle stereo camera 120 is further installed on the roof of each of the vehicles 100, 102, and 104 so that a stereoscopic image can be taken. Since the side image may not appear properly, it is possible to convert the overall appearance image into a 3D stereoscopic image by acquiring the side image as a stereoscopic image image and then synthesizing it with a planar image.

In addition, the RF transmitters (R1, R2, R3) is to be received by the drone 200 by oscillating the RF, the oscillated signal has a unique frequency band having a different frequency band for each RF transmitter (R1, R2, R3) Since the RF is included, the drone 200 may identify the RF transmitters R1, R2, and R3 that have oscillated the RF through the received RF.

In addition, the RF transmitter (R1, R2, R3) is controlled by the vehicle controller 110 installed in each vehicle (100, 102, 104) when the drone 200 enters the shooting target ground (that is, the shooting zone), respectively, a single or constant It can be controlled to continuously transmit at intervals.
At this time, the vehicle (100, 102, 104) should be stopped after entering the shooting zone to communicate in a fixed state of the position of the RF oscillator (R1, R2, R3).

On the other hand, the drone 200 is equipped with a drone controller 210 for the control necessary to implement a function, including wireless communication with the management server 300 and the vehicle (100, 102, 104).

At this time, the drone controller 210 is located in the camera 211, the RF receiver 212 for receiving a signal transmitted from the RF transmitter (R1, R2, R3) and the drone 200 is located An altimeter 213 for measuring altitude, a coordinate system 214 for checking the GPS coordinates of the point where the drone 200 is currently located through communication with a satellite, and position information and a coordinate system 214 received by the RF receiver 212. A calculator 215 for calculating a distance on the ground to each of the RF transmitters R1, R2, and R3 using the position information checked by the < RTI ID = 0.0 > and the altimeter < / RTI > A location information synthesizer 216 for synthesizing the location information on the captured image of the video image photographing zone by checking the distance information and the location information received by the RF receiver 212, and a drone memory 217 for storing the synthesized image image; It includes.

In this case, the camera 211 is a general camera for capturing the shooting zone, analog or digital may be applied, but particularly preferably a stereo camera for the drone to secure a stereoscopic image.

In addition, the RF receiver 212 checks and distinguishes RF included in the oscillation signal corresponding to different frequency bands transmitted by the RF transmitters R1, R2, and R3, and distinguishes the distinguished information by the drone controller 210. do.

In addition, the calculator 215 is a vehicle (100, 102, 104) equipped with RF receivers (R1, R2, R3) and GPS receivers (G1, G2, G3) disposed in at least three of the circumference of the shooting zone as shown in the example of FIG. ) And an image of the size of the unit space that the camera 211 mounted on the drone 200 can shoot at one time through the information provided by the drone 200 hovering at an upper predetermined height in the shooting zone. How far apart from the drone 200 to insert the coordinate values, that is, the location information into the image to accurately position the vehicle 100, 102, 104 so that the image processing module 330 can accurately process the image. It is to calculate whether there is.

At this time, the position of the drone 200 is known through the coordinate system 214, and the ground point directly below the drone 200 of the photographing zone is known through the altimeter 213, and each RF transmitter (R1, R2, R3). Since the distance to each other can be known through the speed of the RF and the time received by the RF receiver 212, the distance from the ground point directly below the drone 200 in the shooting zone to each RF transmitter R1, R2, and R3 is a right triangle. As a result, it is calculated by Pythagorean theorem.

In this way, the coordinate values obtained by the GPS receivers G1, G2, and G3 based on the ground points directly below the drone 200 in the shooting zone, and the distance information from the reference point to the RF transmitters R1, R2, and R3 are known. Therefore, in the end, it is possible to display the position information of the RF transmitters R1, R2, and R3 on the image image of the shooting zone, and when the image processing is performed based on the respective position information when the image image of the shooting zone is processed. Accurate image processing becomes possible.

The drone memory 217 records the captured image obtained by synthesizing the position information in the form of a storage material and transmits the image to the image processing module 330 according to the control signal of the drone controller 210.

The drone memory 217 may be, for example, an external disk having a temporary storage function such as RAM (a recording medium detachable from a USB method or a recording medium in the form of an SD card), a general disk, or a removable hard disk. It could be a drive.

On the other hand, the management server 300 is installed at a remote location, and includes a server controller 310 as a main control unit, the server controller 310 receives the video image necessary for image processing by wireless communication with the drone 200 The server communication unit 320, the image processing module 330 for image processing using the image image received through the servo communication unit 320 and the server connected to the server controller 310 and stores the information transmitted and received Memory 340.

In addition, although not shown in addition to the image processing module 330, the management server 300 is provided with a database (Data Base) for storing information, and a plurality of processing modules (MOD, see FIG. 5) required for calculation, The detailed description is omitted.

However, since a plurality of processing modules including the image processing module 330 perform a great number of repetitive tasks quickly, a lot of heat is generated, and also because they are mounted in the form of a server rack inside the enclosure when the processing modules (MODs) are replaced or used. To remove this, many safety accidents occur, such as opening the door of the enclosure itself, unscrewing and tightening the bolts in a narrow space, resulting in increased fatigue, and injuries to the fingers due to stenosis. Unless the cooling equipment is installed, the deterioration problem due to heat generation causes a drastic deterioration of the performance of the system.

Thus, in the present invention, as shown in Figure 5, the base plate 400 is provided on the bottom surface on which the management server 300 is installed.

At this time, the base plate 400 has a shape in which the square groove 410 is formed in a concave-convex shape with a predetermined interval in the width direction.

The square groove 410 is also a circulation passage of air, but may be utilized as a cold air supply passage for supplying cold air as needed.

When the temperature inside the space in which the management server 300 is installed rises rapidly, when supplying cold air in conjunction with an air conditioner, the supply is provided through the square grooves 410 instead of the upper part of the space, so that the uniform cooling is possible. It is configured to increase the cooling efficiency of the block-type board 500 installed on the base plate 400.

As described above, in the present invention, a plurality of processing modules (MOD) are arranged in an open state so that they are always cooled by air, and thus the cooling efficiency is good, and since the space is open, there is no need for maintenance work such as replacement in a narrow space. First of all, since the worker can work in a horizontal state by rotating the block-type board 500 in a straight line, it is possible to obtain many advantages such as improving work efficiency, reducing working time, preventing accidents, and improving convenience.

In addition, the block-type board 500 is formed with a plurality of slots 510 at regular intervals on one side.

The slot 510 is a space in which the modules including the DB or the image processing module 330 constituting the management server 300, that is, the processing module MOD is mounted, are screwed to maintain a stable connection relationship. do.

Although the block-type board 500 is not shown, it is designed to be supplied with commercial power, which may be considered to be an extension of a general board mounting structure in a block form.

In addition, the lower portion of the block-shaped board 500 is provided with a fan box 520 at intervals with the lower end, the fixing plate 530 is fixed to the lower surface of the fan box 520.

At this time, the fixing plate 540 is fixed vertically to the fixing plate 530, the horizontal stand 550 is integrally fixed to the upper end of the fixing stand 540 in a direction orthogonal thereto, and the horizontal stand 550 Both sides of the upper end of the block-type board 500 is rotatably fixed by the rotation shaft 560.

Therefore, the block-type board 500 is excited while being slightly spaced apart from the upper end of the fan box 520, and can be freely rotated because its upper end is hinged around the rotation shaft 560.

For example, it can be rotated clockwise or counterclockwise.

Of course, since the lead wire for the electrical supply is connected, the rotation direction is preferably determined in a specific direction, and the lead wire should be designed so that the lead wire does not break when the block-type board 500 rotates using the flexible coiled lead wire.

In addition, as illustrated in FIG. 6A, an air flow path 570 is formed in the block-shaped board 500, and a lower end of the air flow path 570 is formed on an upper end of the fan box 520. It is arranged to communicate with the slit-shaped blower (SLT) formed long in the longitudinal direction, the cross-flow fan (FAN) is built in the fan box 520.

In addition, a suction hole 522 is formed on one side of the fan box 520, and a plurality of discharges communicating with the air flow path 570 on the wall between the slots 510 of the block-type board 500. A ball 524 is formed.

Therefore, when the crossflow fan (FAN) is operated, the dry indoor air is sucked into the suction hole 522, and then flows through the air passage 570 and the discharge hole 524 sequentially through the air vent (SLT) and is discharged into the slot ( The processing modules MOD mounted in the 510 are cooled.

In particular, the temperature drop phenomenon occurs when passing through a small hole at a high pressure, so increasing the pressure may discharge slightly cooled air which is more effective.

In addition, an auxiliary piece 526 is further fixed to an upper surface of one end of the fan box 520 to restrain the rotation of the block type board 500, and the auxiliary piece 526 penetrates the block type board ( A stopper screw 528 which is screwed to one side of the 500 may be further provided.

Therefore, when the block-type board 500 is fixed, the stopper screw 528 is fastened, and when the block board 500 is rotated for maintenance, the stopper screw 528 may be loosened.

In addition, as illustrated in (b) of FIG. 6, when the heating wire HET that is heated on the fixing plate 530 is arranged, the block-type board 500 may be effectively used when it is necessary to warm the air instead of cooling it. have.

For example, when a cold weather situation occurs and the interior space of the vehicle in which the block-type boards 500 are installed is cooled and needs to be warmed up, if the heating wire (HET) is operated to protect the system, the crossflow fan (FAN) is operated. Heat generated from the hot wire (HET) is spread through the air flow path 570 between the slots 510 and warmed to an appropriate temperature to prevent the modules and DBs mounted in these slots 510 from freezing. .

In another method, as shown in FIG. 7, a hole having a predetermined size is installed in the fixing plate 530 at a position corresponding to the square groove 410, and has a size corresponding to the installation hole 580. The block-type thermoelectric element 590 is inserted into and fixed to the installation hole 580, and the heat absorbing side is disposed upward and the heat generating side is disposed toward the square groove 410.

Then, when electricity is applied, the portion suctioned through the suction hole 522 to blow the slot 510 side is always made of cooled air, and hot air flows toward the square groove 410, so that convection naturally occurs. It can also be configured to smoothly guide the air circulation.

This configuration allows for effective cooling and air circulation.

In addition, the present invention also requires a humidity control function inside the space in which the block-type board 500 is installed for stable driving of the processing modules MOD mounted on the block-type board 500.

To this end, in the present invention, one or two of the plurality of square grooves 410 formed in the base plate 410 may be inserted into the mesh network (MESH) as shown in FIG.

The mesh network (MESH) is a rectangular box-shaped closed member, for example, it can be regarded as a woven network woven fiber.

In addition, the mesh network (MESH) and 8% by weight of yttria powder, 5% by weight of montmorillonite powder, 20% by weight of silica gel to achieve stabilization by including humidity control and insect repellency, deodorant, flame retardancy , A resin composition consisting of 10% by weight of charcoal powder, 3% by weight of resorcinol, 5% by weight of hydrolyzed keratin, 3% by weight of coffee powder and the remaining acrylic emulsion into a spherical shape of 4-5 mm diameter The moisture absorbing ball is filled.

At this time, the yttria is added for the hygroscopic and deodorizing effect, and the montmorillonite powder is added for the insecticidal effect while improving the adsorption efficiency of the fine foreign matter because it has strong adsorption and insecticide.

In addition, silica gel is added in the most amount for moisture control as a representative moisture absorbent, charcoal powder is added for dehumidification, deodorization using many pores between the charcoal.

In addition, resorcinol is added to increase the wetting and drying strength and the high temperature resistance to increase the crosslinking strength. Hydrolyzed keratin is added to increase the slip property and to remove the harmful substances, and the coffee powder increases the adsorption function. It is responsible for increasing the surface area.

In order to confirm the adsorption, adsorption, and deodorization characteristics of the adsorption balls thus prepared, a transparent experimental case having a size of 15 cm × 15 cm × 10 cm was made, and the adsorption ball was filled with about 2/3 and charcoal smoke was injected into the inside.

Then, the time taken to absorb and deodorize charcoal smoke was checked.

For comparison, other experimental cases were tested in the same manner with commercially available deodorants in the form of tea bags.

As a result of the test, the hygroscopic ball according to the present invention was adsorbed and deodorized in 38 minutes, and almost no smell was found. In addition, the comparative object took 48 minutes, but the smell remained.
