Description

Drone System For Supporting Cadastral Boundary Restoration Measurment}

The present invention relates to a drone system for supporting cadastral boundary restoration surveying, and more particularly, a method for quickly and accurately responding to the mark of a laser launched to the ground during a stationary flight of a flying drone as a method for a modified cadastral boundary surveying of the terrain. It relates to a drone system for surveying support for cadastral boundary restoration that can easily mark and restore cadastral boundary points.

In general, cadastral boundary surveying for boundary display mostly uses a method using a total station and an electronic flat panel system, but a lot of time and manpower are being invested in measuring and displaying a single point, so improvement is needed.

Moreover, to mark the boundary, workers measure the ground distance of the area by using distance measuring tools to mark the ground boundary points of the area based on the topographic information data provided by the total station and the electronic flat plate system. As the ground boundary points are identified, a lot of time is required to identify the boundary points, and the input of manpower is bound to increase.

In addition, even if the cadastral boundary surveying of a specific area is performed, the terrain is transformed according to the development of a large-scale project, for example, in relation to government policy or investment by private organizations. In performing the same task again, there is a problem of repeating the inefficient cadastral boundary surveying, which requires a lot of time and a lot of manpower as before.

In order to mark the ground boundary points, identification of boundary points must be prioritized, and when these boundary points are identified, workers relocate the boundary points by installing a horse tree and lacquering a crosshair of about 1M around the horse tree to mark the boundary points again. Will be marked.

As such, since the cadastral boundary surveying work has to be repeated according to frequent changes in the terrain due to factors such as regional development issues, technical development in which the cadastral boundary surveying method needs to be fundamentally changed is urgently needed.

Meanwhile, the patent documents disclosed in the following prior art documents may be referred to as technologies related to drone systems.

Patent Document 001: Patent Document No. 10-1915294

The present invention for solving the above-described problems is to provide a drone system for supporting cadastral boundary restoration surveying to easily and easily perform the entire operation from surveying cadastral boundaries of terrain to restoration of cadastral boundaries. It has a purpose.

The present invention for achieving the above-described objects is a drone that flies over the sky and photographs the terrain, a control terminal that wirelessly controls the flight of the drone, a server for editing and restoring data information on the terrain photographed from the drone, And based on the data information edited and restored from the server, to identify the flight transit point of the drone, and to quickly respond to the firing marker point of the laser launched as an intellectual border marker in the stop flight of the drone to indicate the ground boundary point. There is a feature of a drone system for cadastral boundary restoration survey support including a portable terminal that guides and guides an operator.

The server has a characteristic feature of a drone system for supporting cadastral boundary restoration surveying to which a method of processing a position of a transit point of a flight path for editing data information on the terrain is applied.

In the method of processing the location of the transit point of the flight route, the data file related to the terrain may be edited through a series of work processes through sequential execution of a route editing unit, a file conversion unit, a route guidance program, and a route guidance map. The data file finally converted by the route guidance map is restored to a portable terminal, and the portable terminal provides the operator with a flight stop point of the drone and a laser launch indication point according to the stopped flight of the drone based on the restored data file. There is a feature of the drone system for cadastral boundary restoration and survey support that is informed by guidance.

The data edited in the path editing unit is stored as a file extension that can be opened in the path guidance program through the file conversion unit, while the file opened from the path guidance program is displayed as a map in the latest state through the path guidance map. The map is edited, and the route guidance map is characterized by a drone system for supporting cadastral boundary restoration surveying that converts the map into a file having a file extension operable in the portable terminal.

The drone displays a laser from a laser device to a boundary point of the ground to mark an intellectual boundary during a stationary flight, and the response to the laser launch mark according to the stop flight of the drone is provided by the mobile terminal. There is a feature of a drone system for cadastral boundary restoration and survey support that is performed through the point of the drone.

The stationary flight of the drone is detected through a detection sensor installed in the drone, and the detection sensor is a contact type electrical contact between the electrode rod and the conductor box according to the degree of air wind strength encountered in the flight direction generated during the flight of the drone. The drone does not detect the flight stop when it is energized, but in the non-contact time difference between the electrode and the conductor box, the drone detects the flight stop and transmits the authorization signal necessary for the laser launch of the laser machine. The drone system has a feature.

The present invention as described above is capable of grasping the flight transit point of a flying drone in real time through a mobile terminal in a line of work ranging from cadastral boundary surveying of terrain to restoration, and stopping the drone in the process of flying the drone. Since it is possible to quickly and easily identify the point of laser emission according to flight and mark the ground boundary point through the map file operated by the mobile terminal, it is easy to work in a line from surveying to restoration of cadastral boundary. Most of all, unlike the existing cadastral boundary surveying method, which has been caused by excessive time-consuming and excessive manpower input, the time-consuming and manpower input involved in cadastral boundary surveying is reduced, and thus cost can be saved.

The present invention should be interpreted in a manner that includes the scope of the rights to the technical idea through various modified embodiments, only these embodiments make the posting of the present invention complete, and common knowledge in the technical field to which the present invention pertains. It is provided to completely inform the scope of the invention to those who have it, and the invention is only defined by the scope of the claims.

Moreover, the drawings attached to the present invention are attached as a way to help the understanding of the description of the present invention to the last, and the technical idea of the present invention should not be interpreted as being limited by the attached drawings.

The drone system for cadastral boundary restoration survey support according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Fig. 1, the present invention is a new cadastral model that has undergone correction and restoration of data information on cadastral boundaries of a drone 100, a control terminal 110 for remotely controlling the drone, and a terrain photographed from the drone. A portable terminal 120 that provides the user with the location of the transit point of the flight path on the boundary, and a server that creates and stores a new cadastral boundary file through editing work to modify and restore data information on cadastral boundary photographed from the drone ( 130).

The drone 100 may be equipped with an infrared camera capable of shooting at night as well as a high-performance camera for terrain shooting, and an automatic flight navigation device capable of automatically flying from the starting point of the flight to the arrival point of the flight is also provided. Can be equipped.

The drone 100 may fly a desired flight distance by wireless remote control according to the operation of the control terminal 110, and automatically fly the desired flight distance based on the flight setting value information set by the automatic flight navigation system. have.

Accordingly, the drone 100 may collect data information on the intellectual boundary of the terrain by photographing with a high-performance camera or an infrared camera of the terrain changed during the flight process. Here, the changed topography can mean the topography itself has changed through a large-scale project-like development process that can bring about a change in the topography itself, such as regional development, and the cadastral boundary display can also be changed in this changed topography. Of course.

Therefore, the cadastral boundary based on the changed topography is changed compared to the existing cadastral boundary, and the necessity to be newly restored through the editing process is required.

As shown in Fig. 2, the data information on the cadastral boundary of the terrain photographed by the drone 100 can be newly restored through a processing method called the transit point position 140 of the flight path in the server 130. In addition, the portable terminal 120 shown in FIG. 1 is a device capable of utilizing the method of processing the transit point position 140 of the flight path in the flight of the drone 100.

The way of processing the position of the transit point 140 of the flight path can make it mandatory to check the position of the drone 100 according to occasional communication between the drone 100 and the control station, and a designated point in the middle of the flight route of the drone 100 The location of the drone 100 can be determined in a way that the drone 100 passes through.

Of course, the drone 100 may be equipped with a wireless transceiver capable of wireless communication with a control station, and such a wireless transceiver may be applied with a DMB broadcast transmission transceiver capable of precise position correction in cm class, so that the location accuracy of drone flight Can be improved.

The method of processing the transit point location 140 of the flight path is used as a means of operating a milestone or landmark that can help guide the path on the flight path of the drone 100. Since the location of the operator cannot be identified and confirmed by the operator's eyes, a unique name is given to a specific milestone or landmark consisting of latitude and longitude, and the drone 100 and the control station communicate with each other based on the name. You can check the location by identifying it. The unique name may be, for example, a 5-character assignment code, but is not limited thereto.

The way of processing the transit point location 140 of the flight route is a route editing unit 141, a file conversion unit 142, a route guide program 143, and a route guide map 144 in the server 130 as shown in FIG. It can be performed through the execution processing process of, and according to the execution processing process, data information on the cadastral boundary of the terrain can be edited in a manner such as correction, addition, or deletion, and can be restored to the updated cadastral boundary.

In the method of processing the transit point location 140 of the flight route, for example, in Korea, among the geographical milestones for the sky near Gimpo Airport, for example, Arisu, Vinyl, Head Office (BONSA), National Highway (GUKDO) ), it is possible to determine the location of the drone 100 in a way that the drone 100 passes a milestone or landmark assigned unique names such as HODOL and HANQU.

Components necessary for implementing the processing method of the transit point location 140 of the flight path include, for example, a route editing unit 141, a file conversion unit 142, a route guidance program 143, and a route guidance map 144. I can.

The path editing unit 141 is activated according to the execution as shown in FIG. 3, and the activated path editing unit 141 can load a course file, and such a course file can be modified while being displayed on a window screen. In addition, the course file may be loaded as a file having a file name (Gimpo Sang-Gong_01), for example. Here, the course file may be data information on an intellectual boundary of the terrain photographed by the drone 100.

When viewing the course file, as shown in Fig. 3, for example, you can check the map with 4 flags stamped on the map, and add one additional arbitrary flag to the milestones of the 4 flags stamped on the map or 4 flag milestones. It can be edited and saved by changing the flag or deleting any one of the four milestones.

For example, you can provide a total of 4 stopover points such as Start/Finish, No. 1 Gasan (stop point), No. 2 Baekhak (stop point), and No. 3 Munbal (stop point). If you need to shoot, you can load the course file, edit it and save it here.

In this way, the modified course file (Gimpo Sang-Gong_01) can be converted to a specific file name extension, which can be achieved through the file conversion unit 142 linked to the path editing unit 141 as shown in FIG. 4.

Here, the waypoints stamped on the map may be used by converting the x,y values of plane rectangular coordinates used for cadastral surveying into coordinates of the flight waypoints of the drone 100.

The file conversion unit 142 may perform file conversion by selecting a file extension for conversion, such as a PRW file, following selection of the course file (Gimpo Sang-Gong_01) to be converted.

That is, as shown in Fig. 4, after the course file to be converted is loaded by pressing the file selection button, a file extension called Path Route Way PRW can be selected. Subsequently, the course file is immediately uploaded, and when the button called Convert is pressed, the conversion of the course file file can be completed.

The PRW file converted in this way may be stored in a file storage path of a specific folder of the server 130 with a file name of Example_text.prw as shown in FIG. 5, for example.

In this way, when the converted PRW file is stored in a specific folder file storage path of the server 130, as shown in FIG. 6, the path guide program 143 may be executed and activated, and the path guide program ( 143), the converted PRW file can be reloaded through a series of processes such as file check, import check to current account, and course check displayed in the window. In this process, the file format is, for example, Figure 7 As shown in the above, the converted PRW file, that is, the file called Example_text_prw, can be called while being displayed in the window only when *.PRW is selected.

When the PRW file called Example_text_prw is loaded, the course is displayed in the course list window as shown in Fig. 8, for example, and when this course is pressed, it is possible to check whether the course is displayed on the map.

The above map can be viewed as the latest map by changing the route guidance map 144 to the latest version as shown in FIG. 9 and executing it. When this map is enlarged, even the road name address can be seen.

In this way, the map displayed in the latest state in the route guidance map 144 may be modified through editing. Editing of the map may be performed, for example, by clicking a right mouse button on a stopover point shown on the map and checking the waypoint edit of the course. Of course, in some cases, it is also possible to edit the route route in the same window as the route route registration information shown in FIG. 10 activated by double-clicking the mouse at the route point shown on the map.

When a window such as the course transit registration information is displayed, as shown in FIG. 10, the course transit may be changed through editing and modification of the name, symbol, and icon, but the desired name, symbol, and icon may be changed. In this way, the course name can also be changed by right-clicking.

In this way, editing of the course file is completed, and then, by right-clicking the mouse on the title of the course file and pressing the Export button, the file extension can be selected as shown in Fig. 11. At this time, the file extension is For example, you can select a format called Path Route Way File (*.qcx).

Thereafter, a file having an extension name of qcx may be stored as a specific folder path of the path editing unit 141 in, for example, a folder called course editing, and the file having the extension name qcx is stored in the path editing unit 141 as shown in FIG. You can copy and paste it to the NewFiles folder of the route map of the same mobile device.

A file with such a qcx extension is a data file containing cadastral boundary information newly restored through editing of cadastral boundaries in the changed terrain.

Of course, the file with the extension name is a file set by selecting the boundary restoration point on the CAD cadastral map or manually entering the survey coordinates.These files are copied and installed on a small computer, for example, configured in the automatic flight navigation system installed in the drone 100. As a result, the drone 100 can fly based on the set file.

The mobile terminal 120 is disconnected from the computer called the server 130 and disconnected, and then turns on the power of the mobile terminal 120 and loads a newly restored course file, that is, a file with the copied qcx extension, and 100) When the driving for flight is pressed, information on the flight end point of the drone 100 is automatically displayed as shown in Fig. 12 below the screen of the mobile terminal 120. Is fixed, but information about the list of transit points can be displayed sequentially according to distance.

At this time, as the drone 100 takes off and moves above the input cadastral map boundary selection point, it stops and flies and fires the laser to the cadastral boundary display point, so that a poleman (a worker carrying a pole) among the workers is a drone. It is possible to mark the boundary point on the ground by moving to the point where (100) is still flying and measuring the cadastral boundary with reference to the laser emission mark point.

After the boundary point is installed, the crosshair of about 1m around the horse's neck is marked with lacquer, and the drone 100 takes a crosshair marked with lacquer above the mark and saves it as a picture or transmits it to the mobile terminal 120 in real time. have.

The crosshairs, which are ground boundary points photographed by the drone 100, are subsequently processed in the server 130 to execute the route editing unit 141, the file conversion unit 142, the route guidance program 143, and the route guidance map 144 Can be edited via

Of course, at this time, a laser device capable of laser emission may be further installed in the drone 100, and a detection sensor for applying a laser emission signal to the laser device by recognizing this when the drone 100 is in stop flight may be further installed. .

The detection sensor is a sensor capable of applying a laser firing signal to the laser device by detecting the stopped flight of the drone in a non-electrical manner through the presence or absence of contact between the electrode rod and the conductor according to the air strength hitting the air wind during the flight of the drone. .

Of course, at this time, a laser device capable of laser emission may be further installed in the drone 100, and a detection sensor for applying a laser emission signal to the laser device by recognizing this when the drone 100 is in stop flight may be further installed. .

The detection sensor is a non-conductive method through the presence or absence of contact between the electrode electrode (E1) and the conductor box (E2) as shown in Fig. 14 according to the intensity of the air wind encountered in the flight direction during the flight of the drone 100. It is a sensor that can apply a laser beam firing signal to the laser device by detecting the stationary flight.

The electrode (E1) is installed vertically while being supported by an elastic member (F) in the conductor box (E2) surrounding it, and the electrode (E1) is the conductor during the flight of the drone 100. Contact with the conductor box E2 due to the strength of air flowing into the inside through the through holes E2a of the ship E2 or contact with the conductor box E2 according to the speed and direction of the drone 100 flight It may be in a state that repeats and non-contact.

Therefore, in the flight process of the drone 100, the electrode E1 is in contact with the conductor box E2, or even for a short moment, the conductor box E2 repeats contact and non-contact with the conductor box E2. The connected ammeter (EM) can determine the current state through the contact between these electrodes (E1) and the conductor box (E2) by measuring current, but the timer (T) connected to the ammeter (EM) is an arbitrary time setting value. Based on the current measurement failure time of the ammeter EM is compared with an arbitrarily set time setting value and is operated when it exceeds, the drone 100 is recognized that it is currently in a stationary flight state. The current measurement disabling time means a non-contact holding time between an electrode and the conductor box.

Here, the time setting value may be set as a time difference in which the current measurement is impossible of the ammeter. For example, when the time difference in which the current measurement cannot be measured by the ammeter is set to, for example, a random 5 seconds It becomes the time set value above, and when the time difference in which the current measurement is impossible of the ammeter, that is, the non-energization maintenance time exceeds the value of 5 seconds (sec), as the timer T is activated, the detection sensor currently operates the drone 100 ) Is detected as being in a stationary flight state, and an application signal necessary for laser emission of the laser device is lowered.

According to the recognition of the stop flight of the drone 100, the detection sensor sends an application signal necessary for launching the laser to the laser device installed in the drone 100 based on the operation of the timer T, so that the laser device is the drone 100 The laser is fired in the direction of marking the boundary point on the ground required for cadastral boundary surveying in the state of flight stop.

As described above, the drone system for cadastral boundary restoration survey support according to the present invention can generate cadastral boundaries newly restored through the process of processing cadastral boundaries in the flowchart method of FIG. 13.

The terrain can be transformed over time, for example, in the same way as the development of large-scale projects in the region, and cadastral boundaries may also change according to the transformed terrain. Therefore, it is possible to restore the cadastral boundary in line with the changed cadastral boundary through editing operations such as correction, deletion, and addition of cadastral boundaries by shooting the transformed terrain to be photographed by flying a drone.

To this end, a drone flight (S10) process may be preceded as shown in FIG. 13 in order to photograph the terrain. In the process of flying the drone (S10), the drone 100 may be limited to a desired terrain and flying through the control terminal 110 or the automatic flight navigation system.

Accordingly, the drone 100 may fly over an area over the topography of a specific area and collect data on the existing intellectual boundary included in the data on the topography through photographing by a high-performance camera.

In this way, after the drone flight (S10) process is preceded, the process of comparing the stopover information of the drone flight path (S20) may be performed.In the comparison of the stopover information of the drone flight path (S20), the collected in the process (10) This is a process of comparing'data information on existing cadastral boundaries' with'data information on standard cadastral boundaries' included in the transit point location 140 of the flight route stored in the server 130.

If the'data information on the existing cadastral boundary' is compared with the'data information on the standard cadastral boundary', the'data on the existing cadastral boundary' is placed in the transit point location 140 of the flight route stored in the server 130. Information' is also considered to be reflected, and the drone re-flighting (S30) process based on the reflected cadastral boundary data described later can be performed immediately, but if the'data information on the existing cadastral boundary' is the'data on the standard cadastral boundary' If it is not compared with'information', the process of reflecting the existing cadastral boundary data (S25) on the flight path based on the cadastral boundary data described later prior to the execution of the drone reflight (S30) process based on the reflected cadastral boundary data described later It can be done first.

The process of reflecting the data on the existing cadastral boundary to the flight path based on the cadastral boundary data (S25) is'data information on the standard cadastral boundary' included in the transit point location 140 of the flight route stored in the server 130. It refers to a process of editing by reflecting the'data information on the existing cadastral boundary', which is a route editing unit 141, a file conversion unit 142, and a route for the point position 140 of the above-described flight route. It may be viewed as editing of the data file through the guide program 143 and the route guide map 144.

In this way, after the process of reflecting the data on the existing cadastral boundary (S25) on the flight path based on the cadastral boundary data is performed, the drone re-flighting (S30) process based on the reflected cadastral boundary data may be performed.

In the process of drone re-flighting (S30) based on the reflected cadastral boundary data, the drone is able to cover a specific sky area based on the data information in which both'data information on standard cadastral boundary' and the'data information on existing cadastral boundary' are reflected. You can re-flight.

After the process (S30) is performed, a process of photographing the changed terrain (S40) is performed, and the re-flighted drone flies in a specific airspace and photographs the changed terrain unlike the previous one.

After the above process (S40) is performed, the process of editing and restoring cadastral boundary data (S50) is performed, where the'standard cadastral boundary related to the standard cadastral boundary' included in the transit point location 140 of the flight route stored in the server 130 'Data information' and'data information on new cadastral boundaries' based on the changed topographic photographing information are also reflected in'data information on existing cadastral boundaries' and'data information on existing cadastral boundaries' and'data on new cadastral boundaries' Information' can be edited on the basis of'data information on standard cadastral borders' and restored to'other cadastral border data information'.

Of course, the editing work for restoring the'other cadastral boundary data information' is a route editing unit 141, a file conversion unit 142, and a route guidance program 143 for the above-described flight route transit point location 140. , And through the route guidance map 144, a line of editing operations such as correction, deletion, or addition of flight stops may be performed.

In this way, the data reborn as'other cadastral boundary data information' in the process (S50) is reflected in the process (S25) to function as'data information on the new standard cadastral boundary', and in the process (S20), the drone If the comparison of the waypoint information of the flight path is not made, the above process (S25) reflecting the'data information on the new standard cadastral boundary' is performed, and then the above process (S30) in which the drone is re-flighted is performed. Through repetition, it is possible to easily perform restoration work on cadastral boundaries according to terrain transformation.

Therefore, even if the terrain is changed, if the above-described processing processor is performed, the data on the cadastral boundary is easily updated in such a way that the data on the cadastral boundary is edited and restored according to the change of the terrain. It can also be done easily.
