Description

[0001] The present invention relates to a digital map making system using 3-dimensional data,

The present invention relates to a digital map technology which can reliably perform a role of a reference point in the production of a digital map with reference to an underground facility as a reference point, detect and modify, when there is a change in a reference point, And the reference point applying device for this purpose includes an external rotating device equipped with a solar cell and a fixed type container installed inside the rotating device with a coordinate signal transmitter of the reference point applying device incorporated therein, The photovoltaic cell can be protected from contamination by fine dust, ultrafine dust, and dust, and at the same time, the amount of the cleaning liquid used for cleaning the solar cell is maintained at an appropriate amount, and the lifetime of the foreign- The present invention relates to a digital map production system in which accuracy is improved using data.

Generally, a digital map recording three-dimensional position information is produced from images collected through aerial photography and ground photographing, and thus the images collected for the production of the digital map are transferred to a complete image And is completed with a numerical map.

In order to construct the digital map, it is necessary to establish a precise connection between the images in order to interconnect the collected images. In order to set the reference accurately, it is necessary to capture the accurate aerial image image and the ground image image according to the GPS coordinates Should be preceded. That is, the aerial photographing and the ground photographing are accurately performed according to the GPS coordinates, and accurate aerial image images and ground image images are collected according to the GPS coordinates.

In order to achieve this, a reference point is required as a reference of shooting, and a device capable of displaying such reference point as an external is also required.

Conventionally, various apparatuses have been proposed in which a camera receives a signal or light so that the position of the corresponding point can be recognized. However, most of the conventional devices have a technology that enables the camera to accurately receive and photograph the light irradiated by itself. Especially, since there is no self-managed function that is protected from external pollution, the life of the device is short. This problem is a problem to be solved urgently because it is a reason why the role of the reference point performed by the device can not be sufficiently exercised.

In addition, when a digital map is produced with reference to an underground facility, a reference point display device is installed at the location of the underground facility to display the fixed coordinate value of the underground facility.

However, when the location of the underground facility changes due to the earthquake or subsidence or weakening of the ground, the coordinate value displayed by the reference point display device installed on the ground does not coincide with the coordinate value of the actual underground facility.

In order to solve this problem, Korean Patent No. 10-1116289, entitled " Digital Map Updating System for Recording 3D Position Information along a Base Point Applied to Underground Facilities " has been proposed.

However, in the case of the above-described Korean Patent No. 10-1116289, " a digital map update system for recording three-dimensional position information along a reference point applied to an underground facility ", the position sensing unit of the reference point application apparatus includes the optical sensor and the reflection plate, It is judged whether or not the underground facility is moved through whether the laser beam emitted from the sensor is reflected through the reflector and received again by the optical sensor. Thus, the judgment range for the movement of the underground facility is too narrow, And the connection pipe accommodating the reflector must be exposed to the outside so that the moving direction of the underground facilities can be grasped.

In addition, since the solar cell of the reference point applying device is always exposed to the outside, the solar cell is rapidly polluted in the atmospheric condition where the concentration of at least one of fine dust, ultrafine dust, This leads to an increase in the amount of the cleaning liquid used in the cleaning liquid supply device and a frequent replacement of the foreign material removing member, resulting in an increase in the maintenance and management cost of the reference point application device.

The controller 14 controls the operations of the GPS device 11, the camera 12 and the receiver 13 and controls the GPS device 11 and the receiver 13 so that the GPS position signal from the GPS device 11 and the coordinates And when the GPS position signal has an error equal to or more than the reference signal with the coordinate signal of the reference point applying device A, the photographing area is designated as the re-photographing area.

More specifically, an aircraft which confirms the current position in real time through the GPS device 11 receives coordinate signals from at least three reference point application devices A further. At this time, the three reference point applying apparatuses A transmit the coordinate signals of the same intensity respectively, but the intensity of the coordinate signal finally received by the photographing apparatus 10 due to the difference in distance from the aircraft is different for each reference point applying apparatus A do. As a result, the controller 14 can track the relative position of the aircraft with respect to the positions of the three reference point applying apparatuses A through the coordinate signals received at different intensities, and furthermore, The GPS coordinates values of the absolute position at which the aircraft is positioned can be calculated. Of course, if the GPS coordinate value thus confirmed is compared with the position confirmed by the GPS device 11, the corresponding photographing area is designated as a re-photographing area, and the captured image is separately checked to clearly show that the object is an object of correction.

For reference, the controller 14 stores the dispatch intensity of the coordinate signal transmitted from the reference point applying apparatus A, checks the strength of the received coordinate signal on the basis thereof, and tracks the distance of the reference point dispensing apparatus A . Accordingly, the controller 14, which has received at least three coordinate signals as described above, can track and confirm the position of the aircraft relative to the position of the reference point applying apparatus A through a known and common triangulation method.

FIGS. 4 to 7 illustrate operation states of the reference point applying apparatus according to the embodiment of FIG. 2. Referring to FIG. 4, operation states of the reference point applying apparatus according to the present embodiment will be described.

The worker firstly fixes the reference point applying apparatus A on the floor where the underground facilities 1200 set as the reference point is installed and connects the connection pipe 1110 with the underground facilities 1200. Then, the operator sets each electric component to the usable state via the input device i.

At this time, the operator inputs the absolute coordinates of the position where the reference point applying apparatus A is installed in the control unit 900 of the reference point applying apparatus A, and transmits the coordinate signal of the absolute coordinates inputted by the control unit 900 to the transmitter 700 To the outside.

The control unit 900 of the reference point applying apparatus A receives the illuminance signal from the illuminance sensor 800 and drives the elevator 600 to transmit the illuminated signal to the transmitter 700 As shown in Fig. Therefore, the transmitter 700 can be placed at a relatively high position and exhibit a high transmission rate. At this time, the solar cell 200 converts solar energy from the sun into electric energy and stores it.

When the airplane is flying over the reference point applying apparatus A for aerial photographing in the above-described state, the receiver 13 of the photographing apparatus 10 receives the coordinate signal (A) from at least three reference point applying apparatuses A, . At this time, the controller 14 of the photographing apparatus 10 processes the coordinate signal received from the reference point applying apparatus A to confirm the position of the aircraft with reference to the reference point applying apparatus A, 11), and when the difference between the coordinate signals is equal to or greater than a predetermined reference value, the region is set as the re-photographing region, and the photographed image image is separately checked so that it can be reflected in the drawing.

On the other hand, the aerial photographing is usually carried out during the day, and the reference point applying device (A) does not need to be operated at night. The control unit 900 of the reference point applying apparatus A receives the illuminance signal indicating that the surrounding environment is dark from the illuminance sensor 800 and drives the elevation apparatus 600 to transmit the illuminating signal to the transmitter 700 of the reference point applying apparatus A. [ .

Then, the control unit 900 of the reference point applying apparatus A drives the trolley driving apparatus M to rotate the trolley 120. At the same time, the control unit 900 of the reference point applying apparatus A operates the cleaning liquid supply apparatus 300 and the air injection apparatus 400. Then, as shown in FIG. 5, the cleaning liquid supply device 300 supplies the cleaning liquid toward the rotary 120, and the air injection device 400 injects air toward the rotary 120.

At this time, the solar panel 210 of the solar cell 200 rotates along the rotating shaft 120, dust is removed by the air injected from the air injector 400, and the cleaning liquid injected from the cleaning liquid supply device 300 The surface is cleaned.

Thereafter, when the rotor 120 continuously rotates, the solar panel 210 comes into contact with the foreign material removing member 500 as shown in FIG. 6, and the residual dust and the cleaning liquid The foreign matter mixture liquid is freely dropped between the base 110 and the clearance of the rotating body 120 and is accommodated in the foreign matter receiving mechanism 130 while the mixed foreign matter mixed liquid is cleaned by the foreign body removing member 500. [

Meanwhile, some mixed liquids that flow into the spinneret 120 when the spinneret 120 rotates freely fall before being contacted with the foreign material removing member 500 and are accommodated in the foreign matter receiving mechanism 130.

The control unit 900 of the reference point applying apparatus A may include a rotary driving device M, a cleaning liquid supply device 300, an air injection device 400, Stops the driving of the reference point applying device A so that the reference point applying device A is in the initial state as shown in Fig.

The control unit 900 of the reference point applying apparatus A drives the elevating apparatus 600 and the transmitter 700 as described above so that the coordinate signal of the reference point applying apparatus A is transmitted.

In the case where the underground facility 1200 connected to the reference point applying apparatus (A) fixedly installed on the ground and the connection pipe (1110) is moved by the collapse of the ground, earthquake, construction or the like, The connection pipe 1110 is bent in the moving direction of the underground facility 1200. The laser light oscillated by the optical sensor 1120 does not reach the reflection plate 1130 due to the warping of the coupling tube 1110 and collides with the inner wall of the coupling tube 1120. Therefore, the light receiving unit of the optical sensor 1120 does not receive the oscillated laser light, and thus the optical sensor 1120 outputs the movement signal when the laser light is not received by the light receiving unit. The control unit 900 having received the movement signal transmits the identification signal to the second transmitter 1000 and the second transmitter 1000 wirelessly transmits the identification signal to the reference point application apparatus A. [ The manager receives the movement signal transmitted by the second transmitter 1000 and recognizes that the position of the reference point applying device and the location of the underground facility do not coincide with each other and can take measures quickly.

Therefore, it is possible to provide precise three-dimensional position information of underground facilities by directly connecting the underground facilities and the reference point application apparatus in the above-described manner when producing a digital map requiring precise location information of the installed facilities or facilities in the ground, When the location of the underground facility is moved, it can be immediately detected and corrected, and the digital map can be updated.

The digital map maker 20 includes an image image DB 21 for storing image images collected by the photographing apparatus 10, a figure image DB 22 for storing a figure image drawn on the basis of the image image, A coordinate synthesizing module 24 for synthesizing GPS coordinates in a video image or a picture image, an image drawing module 25 for creating a drawing image based on the image image, And an input / output module (26) for outputting a drawing image and generating and inputting an input signal for operation of the digital map maker (20). In addition, the digital map maker 20 links concrete geographical and geographical information based on a GIS (Geographic Information System) to an illustrated image so that the user can obtain a digital map that can output relevant information when the corresponding information is clicked on the digital map And an information link module 27 for producing the information.

The image editing module 23 links and edits a plurality of image images collected by the image sensing device 10 to complete one image image. In order to connect different image images, adjustment processing such as size and resolution is performed do. A general graphic editing application may be applied to the image editing module 23, and a known and common program may be applied to output and edit a three-dimensional image. As described above, the video image requiring re-imaging is processed so that it can be replaced at any time during editing. When a new video image is inputted by re-shooting, the video image at the corresponding position is updated and updated, So that the accuracy can be guaranteed.

The coordinate synthesizing module 24 synthesizes GPS coordinates, which are three-dimensional position information, on a video image or a drawn image, and ordinarily coordinates coordinates that are three-dimensional position information based on a reference point indicated in a video image or a drawing image. The reference point may be displayed in the process of creating a video image or a drawn image, and the display method may include a natural display method through shooting or an artificial display method through drawing.

The image drawing module 25 generates a drawing image as a background of the digital map by performing a drawing operation on the basis of the image image. It is also possible to use a drawing machine for direct drawing in writing. However, An application in a manner of recording on a computer may be applied. The application-based image drawing module based on a video image is a publicly known technique that is widely used in the field of digital map production, and therefore, a description thereof will be omitted here.

The information link module 27 links various pieces of information recorded in the GIS system to corresponding points in the displayed image so that linked information can be output when the user clicks the corresponding point. An object to be linked to specific information of the GIS system is displayed on the figure image as a target image in the drawing image creation process.

The completed numeric map is output through the input / output module 26
