Subsequently, the terrain to be built in the city center is a three-dimensional object of various shapes. The position measuring instrument 100 is disposed at each vertex of the terrain and receives signals of the neighboring other position measuring instrument 100.

7) is mounted on the head 120, and the head 120 is mounted on the head 120 to receive the ultrasound transmitted from the other position measuring instrument 100 It is preferable that the circumferential surface forms a curved surface in order to increase the horizontal reception ratio.

For reference, a curved groove portion 122 for increasing the reception ratio of ultrasonic waves can be formed on the circumferential surface of the head 120.

The rotary tool 130 is mounted with an ultrasonic transmitting device 170 (see FIG. 7) that projects upward from the head 120 and has independent fluidity and emits ultrasonic waves. That is, the rotary tool 130 equipped with the ultrasonic transmitting device 170 can be disposed at the top of the position measuring instrument 100 so that the ultrasonic wave can be effectively transmitted.

FIG. 6 shows the position measuring device of FIG. , FIG. 7 shows the combined state of the position measuring instrument of FIG. 6, and FIG. 8 shows the state where the position measuring instrument of FIG. 7 is arranged to be inclined.

The position measuring apparatus 100 according to the present invention is constructed such that the support table 110, the head 120 and the rotation tool 130 are sequentially constructed as described above and the control device 140 is installed in the support table 110 An ultrasonic receiver 160 is installed in the head 120 and a laser 150 and an ultrasonic transmitter 170 are installed in the rotary shaft 130.

The support base 110 includes ring-shaped first and second tubes 116 and 116 'horizontally fixedly arranged along the inner surface of the support tube 112 and first and second tubes 116 and 116' , Two hydraulic machines 117 and 117 ', and a boundary plate 118 horizontally disposed between the first and second tubes 116 and 116'. At this time, the first and second tubes 116 and 116 'are injected with a fluid having a large pressure change according to an external pressure.

More specific details are described below in more detail.

The control unit 140 is installed in the cavity of the support tube 112 having the shape of a mouthpiece to confirm and store the information received by the ultrasonic receiver 160 and to control the operation of the laser 150 and the ultrasonic transmitter 170 .

The controller 140 is provided with a control panel 142 and the control panel 142 can be protected by a door 112a formed on the outer surface of the support tube 112 so as to be openable and closable.

Accordingly, the measurer opens or closes the door 112a to manipulate or protect the control panel 142.

On the other hand, the controller 140 further includes a storage unit 143. [ The storage unit 143 stores distance information and direction information from the ultrasonic receiving apparatus 160 to the neighboring other position measuring apparatus 100 and may be a USB device or an MD that can be detached from the controller 140 It will be possible.

The thus separated storage means 143 is collected from the position measuring machines 100 so that the image acquirer 30 can process the same.

Subsequently, the control device 140 may further include an alarm lamp 144. [ The alarm lamp 144 operates according to the set command of the control panel 142 receiving the signals of the first and second hydraulic heaters 117 and 117 ', which will be described below again.

A transparent window 112b may be formed on the door 112a covering the control panel 142 so that the alarm lamp 144 can be visually confirmed.

As described above, the head 120 has a ring shape having a through hole 121 through which the support tube 112 is inserted at the center, and a circumferential surface has a curved groove portion 122 for enhancing the reception efficiency of ultrasonic waves . The ultrasonic receiving apparatus 160 is mounted on the head 120 having such a structure.

The ultrasonic receiving apparatus 160 includes a sensing module 161 for sensing ultrasonic waves collected in the groove 122, a light receiving module 162 for receiving laser light emitted from the laser 150, a sensing module 161, And a control module 163 for processing ultrasound information and laser light information sensed and received by the light receiving module 162 and transmitting the ultrasound information and the laser light information to the control device 140 through the second line L2.

At this time, a plurality of detection modules 161 and a plurality of light-receiving modules 162 are independently arranged in a row and independently receive ultrasonic waves and laser beams. The detection module 161 and the light receiving module 162 are both identified by a unique code and the control module 163 detects the detection module 161 and the light receiving module 162, And transmits the sensed ultrasonic wave information, the laser light information sensed by the light receiving module 162, and the arrangement data to the control device 140.

The ultrasonic receiving apparatus 160 is for receiving ultrasonic waves transmitted from another neighboring position measuring instrument 100 and confirming the distance and position to another neighboring position measuring instrument 100. The control module 163 controls the ultrasonic receiving apparatus 160 so that the predetermined intensity And confirms the distance between the position measuring device 100 and the position measuring device 100.

In addition, it is possible to track the direction of another neighboring position measuring device by checking the light receiving position of the laser beam received by the light receiving module 162. The laser 150 will be described in detail.

For reference, a detection module 161 for detecting ultrasonic waves and a light receiving module 162 for receiving laser beams are disposed along the outer circumference and the inner circumference of the head 120, respectively, so that ultrasonic waves and laser beams To be detected.

In addition, it is preferable that the inner surface of the head 120 is closed with a transparent body 123 through which laser light can pass, thereby increasing the transmittance of the rare low light.

A support jaw 115 may be formed around the support tube 112 for stable seating of the head 120 to enable attachment and detachment between the head 120 and the support base 110.

The rotary tool 130 is inserted into the through hole 121 of the head 120 in a spherical shape having a hollow for mounting the ultrasonic transmission device 170 and the laser 150, 112 are protruded from the anchor 131.

At this time, the anchor 131 may surround and protect the first line L1 connected to the controller 140 for controlling the laser 150 and the ultrasonic transmitter 170.

The laser 150 has a light gun 151 facing the light receiving module 162 of the ultrasonic receiver 160 and irradiates the laser light to the light receiving module 162 in accordance with the control signal of the controller 140.

At this time, as described above, the light receiving module 162 is arranged around the inner surface of the head 120, and a unique code is set for each spot, and the laser light is independently received.

That is, when the light receiving module 162 independently disposed along the inner surface of the head 120 transmits the laser light received by the controller 140 to the control device 140, the control device 140 determines which light receiving module 162 It can be traced in the direction centering on the position measuring device 100 by confirming that the laser beam of the laser 150 is received.

The support tube 112 is partitioned with the controller 140 and a partition wall 113 for waterproofing and the first and second gels G1 and G2 having different densities are injected into the upper portion of the partition wall 113 And the rotary tool 130 are arranged to float on the surface of the first and second gels G1 and G2.

That is, when the first gel G1 is a liquid having a density higher than that of the second gel G2, as shown in Fig. 7, the first gel G1, the second gel G2, .

For reference, the spinneret 130 will float on the surface of the first and second gels G1 and G2 by self buoyancy regardless of density.

The diameter of the rotary tool 130 is set to be larger than the diameter of the support tube 112 and smaller than the diameter of the through hole 121 in order to make the rotary tool 130 stable and free floating.

On the other hand, it is preferable that the second gel G2 directly contacting with the rotary tool 130 is made of a material having a high viscosity. This is to prevent the rotation hole 130 from moving unsteadily due to excessive movement of the second gel G2 and a wing.

The boundary plate 118 disposed between the first and second tubes 116 and 116 'is made of a material having a density lower than that of the first gel G1 and a density higher than that of the second gel G2, G1, and G2, respectively.

For reference, a through hole 118a through which the anchor 131 of the rotation hole 130 passes is formed in the boundary plate 118. [

Subsequently, the rotating shaft 130 is made of a magnet having its own magnetic force, and a mark capable of confirming the polarity can be inserted into the surface of the rotating shaft 130.

As described above, if the rotary tool 130 is placed on the water surface after the first and second gels G1 and G2 are injected into the support tube 112, the rotary tool 130 can automatically perform the function of the compass While the south pole is facing north.

At this time, the anchor 131 is inserted into the first and second gels G1 and G2 so that the rotation hole 130 is stabilized.

In addition, although not shown, a pair of bars centering on the rotary shaft 130 may be disposed opposite to each other, and the rod may be made of a magnetizable material or may be made of a permanent magnet so that the effect of the compass can be maximized .

The ultrasonic transmitter 170 is mounted on the rotary tool 130 and randomly transmits ultrasonic waves under the control of the controller 140.

At this time, the intensity of the ultrasonic waves is set so that all the position measuring devices 100 are constant, and the appearance of the terrain can be tracked based on the collected information.

Since the position measuring device 100 according to the present invention is disposed at a reference point on the ground surface, the position measuring device 100 may be inclined as shown in FIG. 8 depending on the surface state of the ground surface.

 The tilted arrangement of the position measuring instrument 100 makes it impossible to horizontally irradiate the laser light to the light receiving module 162 and restricts the direct sensing of the ultrasonic wave transmitted horizontally, which is disadvantageous in the distance measurement between neighboring position measuring instruments. can do.

Therefore, it is possible to include a function of warning the position measurer 100 when the position measurer 100 is inclined as shown in Fig. 8 so that the measurer can correctly position the position measurer 100 according to the surface state of the ground surface have.

8, even if the position measuring instrument 100 is inclined, the first and second gels G1 and G2 injected into the hollow of the support tube 112 are kept horizontal, Thus, the boundary plate 118 is also kept horizontal.

However, since the first and second tubes 116 and 116 'disposed on the upper and lower sides of the boundary plate 118 are inclined together with the inclination of the support tube 112, both ends of the boundary plate 118 are connected to the first and second tubes (116, 116 ').

Subsequently, the first and second hydraulic pumps 117 and 117 ', which sense the pressure of the fluid injected into the first and second tubes 116 and 116', sense the change in hydraulic pressure of the first and second tubes 116 and 116 ' 142).

As described above, the boundary plate 118 is positioned between the first and second gels G1 and G2, and is independently positioned regardless of the arrangement of the support tube 112.

Therefore, even if the position measuring instrument 100 is tilted to one side, the boundary plate 118 applies pressure to the first and second tubes 116 and 116 'while maintaining the horizontal state.

That is, the boundary plate 118 will exert pressure on both the first and second tubes 116, 116 'only when the positioner 100 is tilted to one side, The pressure will not be applied to all of the first and second tubes 116 and 116 ', or the pressure will be applied to either one of the first and second tubes 116 and 116'.

When the continuous sensing signal is transmitted from all of the first and second hydraulic pumps 117 and 117 ', the control panel 142 determines that the position measuring instrument 100 is tilted and operates the alarm lamp 144 according to the set contents.

The unexplained draw-out symbol "114" is a draw-in line formed in the partition wall 113. The first line L1 connecting the control unit 140 to the laser 150 and the ultrasonic transmission apparatus 170 It is a through space.

The undrawn drawing symbol "P" is a member for closing the inlet path 114 and blocks the first and second gels G1 and G2 from flowing into the control device 140 through the inlet path 114. [

The unexplored drawing symbol "111" is a drawing of a support which is a constituent of the support 110. The position indicator 100 includes a support base 110, a head 120 and a rotation tool 130, So that the lower end thereof is extended and formed so as to maintain the present position stably without shaking.

The unexplored lead-out symbol "141 " is a lead-out code which is inserted into the lead-in path 114 and guides the first line L1 to the control device 140. [

Hereinafter, the correction operation of the image drawing system of the feature item using the reference point according to the present invention will be described in detail.

Step 1

And the position measuring device 100 is disposed at the reference point P of the terrain.

Step 2

After the position measuring instrument 100 is physically stabilized, the state of the rotation tool 130 is observed.

At this time, it is confirmed whether the rotary tool 130 of all the position measuring machines 100 located at the reference point P of the terrain is positioned in the same direction.

Step 3

The control device 140 of each position measuring instrument 100 is operated through the control panel 142 to confirm the inherent code of the light receiving module 162 that has received the laser light of the laser 150, And determines the direction based on the module 162.

When the position of the rotary tool 130 is determined and the laser 150 is irradiated with the laser light in parallel with the position of the rotary tool 130 facing the forward direction of the light gun 151 of the laser 150, The light is irradiated straight toward north, and the light receiving module 162 receiving the light is immediately north.

Step 4

The control device 140 determines a direction around the position measuring instrument 100 to which the optical receiving device 140 belongs through the laser light reception of the light receiving module 162.

Step 5

The control device 140 of each position measuring instrument 100 is operated through the control panel 142 so that the ultrasonic transmitting device 170 emits ultrasonic waves having a constant frequency band and intensity.

At this time, in order to prevent the interference of the ultrasonic waves and to confirm the precise position of the neighboring position measuring device 100, the operation of the position measuring device 100 positioned at the reference point P of the terrain is sequentially performed one by one desirable.

That is, when the direction of all the position measuring machines 100 is determined in the fourth step, the ultrasonic transmitting apparatus 170 operates one by one for each of the position measuring machines 100 and makes ultrasonic waves to be transmitted to other neighboring position measuring machines on both sides, The ultrasonic transmitter of the other position measuring instrument which receives the ultrasonic wave transmits an ultrasonic wave so that another position measuring instrument neighboring the other position measuring instrument receives the ultrasonic wave.

Step 6

The ultrasonic waves of the neighboring position measuring devices are independently received by the independent sensing module 161 disposed along the circular head 120.

As is well known, since the ultrasonic waves are transmitted in the form of concentric circles centering on the position measuring instrument 100, and the sensing module 161 is disposed in a circular shape, the detection module (s) directly received from the ultrasonic transmitting device of the neighboring position measuring instrument 161 is relatively higher than the reception sensitivity of the ultrasonic waves received by the other sensing module 161. [

That is, the position measuring device 100 can confirm the position of the neighboring position measuring device which transmitted ultrasonic waves through the reception sensitivity.

Step 7

The control module 163 confirms the position of the sensing module 161 having the highest sensitivity among the sensing modules 161 that have received the ultrasonic waves, Confirm from which direction the ultrasonic wave of the position measuring instrument is transmitted.

More specifically, the angle between the light receiving module 162 receiving the laser beam and the detection module 161 having the highest receiving sensitivity of the ultrasonic wave is checked so that the neighboring position measuring instrument is located at the north And the direction of the neighboring position gauge from the position gauge 100 can be confirmed through the position gauge.

On the other hand, the intensity of the ultrasonic waves emitted from the ultrasonic transmitter 170 is constant.

Accordingly, the position measuring instrument 100 receiving the ultrasonic waves transmitted from the neighboring position measuring instruments can calculate the distance between the position measuring instruments by confirming the intensity of the ultrasonic waves reduced.

Step 8

The control module 163 of each of the position measuring devices transmits the data to the control device 140 and the control device 140 transmits the data to the storage device 143 And stores the data.

Step 9

The measurer collects the storage means 143 of all the position measuring instruments 100 and inputs them to the image acquiring apparatus 30. The image acquiring apparatus 30 acquires the data from the position measuring apparatus 100), and generates coordinates (x1 to x7, y1 to y7) for each reference point P as shown in Fig.

Since the position measuring apparatus 100 according to the present invention operates independently of the apparatus for measuring GPS, one reference point P among the coordinates x1 to x7, y1 to y7 is set as the origin (0, 0) To create the coordinates of the other reference points.

Step 10

The imager 30 calculates the center point of the polygon having the coordinates (x1 to x7, y1 to y7) as reference points using Equation (1).

Step 11

The new geographical feature image B 'is applied to the displayed image by matching the coordinates of the center point identified by [Equation 1] with the representative GPS coordinates of the geographical feature in the displayed image.

The updated picture image is stored in the digital map DB 10.
