Referring to FIG. 2, the measurement device 100 may include a lidar sensor and a gyro sensor, and the direction in which the light source and the light receiving unit of the lidar sensor are viewed and the imaging means 211 of the terminal device 200 are viewed. The measurement device 100 may be coupled to the terminal device 200 as shown in FIG. 3B so that the direction is the same.

For example, the measurement device 100 may be attached to the terminal device 200 with a permanent magnet or the like having adhesive force.

3A and 3B are diagrams for explaining the coupling relationship between the measurement device and the terminal device in more detail. When the measurement device and the terminal device are combined as shown in FIG. 2, FIG. 3A is a view of the combined devices viewed from the front and FIG. 3B is a view of the combined devices viewed from the side.

As described above, the measurement device 100 and the terminal device 200 may be functionally interlocked to calculate vertical and horizontal distances for a plurality of measurement points, and generate geo data of a facility.

Referring to FIG. 4, the measurement device 100 may include a sensing unit 110, a communication unit 120, and a control unit 130. The sensing unit 110 may include a lidar sensor 111 for measuring a straight line distance from the measurement point and a gyro sensor 113 for measuring an angle formed with the measurement point.

Referring to FIG. 5, a straight line distance Dt is measured through the lidar sensor 111 of the measurement device 100 for a measurement point p of the facility T, and a measurement point is measured through the gyro sensor 113. The angle (At) formed by and the horizon can be obtained. Facility T is buried in the ground, but may be exposed at the time of measurement.

In the present specification, unless a point of time is specifically mentioned, the distance of the end point or the distance to the end point means that the start point is the measuring device 100. Accordingly, the straight line distance Dt of the measuring point means a straight line distance between the measuring device 100 and the measuring point, and the horizontal distance Dh of the measuring point is the horizontal distance between the measuring device 100 and the measuring point, the measuring point The vertical distance (Dv) of refers to the vertical distance between the measurement device 100 and the measurement point. The same technique is used below.

The horizontal distance (Dh=Dt·sin(At)) and vertical distance (Dv=Dt·cos(At)) of the measurement point based on the straight line distance (Dt) of the obtained measurement point and the angle (At) formed with the horizon ). According to an embodiment, the horizontal distance (Dh) and the vertical distance (Dv) of the measurement point may be obtained by passing the values received from the sensing unit 110 to the control unit 130 and performing simple calculations.

The horizontal distance and vertical distance information of the measurement point may be provided to the terminal device 200 through the communication unit 120 of the measurement device 100. According to the present invention, the measurement device 100 and the terminal device 200 may transmit information through a serial communication method. As the horizontal and vertical distances from the measurement device 100 are provided as raw data, it can be utilized for various programs installed in the terminal device 200.

Returning to FIG. 4 again, the terminal device 200 receiving the measurement data shown in Table 1 from the measurement device 100 through serial communication may generate geo data for measurement points based on the received measurement data. . In addition, the terminal device 200 generating the geo data for the measurement points may transmit the geo data to the server 300 to update the geo data for the measurement point in the geographic information system.

The terminal device 200 may include an input/output unit 210, a communication unit 220, a measurement location identification unit 230, a data collection unit 240, and a geo data calculation unit 250.

Hereinafter, an operation performed by the terminal device 200 by the program will be described in detail with reference to FIGS. 6A to 9B along with FIG. 4.

6A is a diagram conceptually showing values that need to be measured through a measuring device in order to obtain geo data of a facility according to an embodiment of the present invention.

Referring to FIG. 6A, an operator (B) having a measuring device 100, a facility (T), and a terrain (B) to define a relative position with the facility (T) adjacent to the facility (T) may be located. . Geo data required to build a geographic information system includes the horizontal distance between the facility (T) and the terrain (B), the horizontal distance between the corner of the facility (T) and the terrain (B), and the depth of the facility (T). Information may be included.

To this end, the measurer extends from one measurement point (p1), one point (p1) of the facility (T) through the measurement device 100 and the first measurement point of the terrain (B) that meets the terrain (B) ( p2), and a straight line distance and angle are measured with respect to the second measurement point p3, which is an edge of the terrain B.

As the distance and angle of the straight line are measured for each measurement point, as described with reference to FIG. 5, the horizontal distance (h(L to p1)) of one measurement point p1 of the facility T, the topography ( Acquire the horizontal distance h(L~p2) of the first measurement point p2 of B) and the horizontal distance h(L~p3) of the second measurement point p3 of the terrain B can do. As described above, when the measuring device 100 is used, an accurate horizontal distance can be obtained even when the measuring device is not perfectly level.

Based on the horizontal distance data thus obtained, the present invention can calculate the horizontal distance between the facility T and the terrain B and the horizontal distance between the corners of the facility T and the terrain B. .

FIG. 6B is based on horizontal distance data obtained from the measurement device 100 (horizontal distance data may be included in measurement data provided from the measurement device 100 to the terminal device 200), to generate geo data. It is a conceptual diagram to explain how to calculate the required data value.

Referring to FIG. 6B, a straight line distance D1 between one measurement point p1 of the facility T and a first measurement point p2 of the terrain B is D1=h(L~p2)-h( L~p1).

The distance D2 between one measurement point p1 of the facility T and the second measurement point p3 of the terrain B is difficult to measure directly. This is because it is difficult for the measurer to measure the distance directly above the facility T. Accordingly, the horizontal distance D3 between the second measurement point p3 and the first measurement point p2 of the terrain B is calculated using Equation 1 of Pythagorean.

Based on the horizontal distance (D3) between the second measurement point (p3) and the first measurement point (p2) of the terrain (B) calculated through Equation 1, one measurement point (p1) of the facility (T) and The horizontal distance D2 between the second measurement points p3 of the terrain B may be calculated as shown in Equation 2.

Through the above process, in the present invention, the horizontal distance between the topography (B) and the facility (T) can be calculated without measuring at the top of the facility (T) through measurement of three measurement points.

7A to 7D show an example in which the steps performed through the programs installed in the terminal device 200 are visually represented.

Referring to FIG. 7A, a location of a facility to be measured by a measurer can be selected through a display. Referring again to FIG. 4, the input/output unit 210 included in the terminal device 200 may interact with a measuring device, including various input means such as a photographing means 211 and various output means such as a display means.

The terminal device 200 may communicate with the server 300 through the communication unit 220 to receive geographic information system data for a location searched by a measurer, and a GPS provided in the terminal device 200 according to an embodiment The geographic information system data may be received from the server 300 by obtaining the location information of the measurer from.

7A and 7B, the received geographic information system data may be visually displayed to a measurement person through output means included in the input/output unit 210. The measurer may check geographic information system data through the terminal device 200 and select a measurement point through the terminal device 200.

As described above, the measurement point selected by the measurer may include one measurement point of the facility T and at least two measurement points of the terrain B. As shown in FIG. 7A, the measurer may select one measurement point of the facility T and select two measurement points of the terrain B as shown in FIG. 7B to designate the location of the measurement point.

The measurement location identification unit 230 of the terminal device 200 may manage information on a measurement point selected by a measurement person through the input/output unit 210.

According to an embodiment, measurement point information designated by a measurement person may be managed as shown in Table 2.

Explanation Type Field Central X coordinate of selection Char CEN_X_COORDI Selection center Y coordinate Char CEN_Y_COORDI X-coordinate at the top left of the selection area Char UP_LEFT_X_COORDI Y-coordinate at the top left of the selection area Char UP_LEFT_Y_COORDI X-coordinate at the bottom right of the selection Char UP_RIGHT_X_COORDI Y-coordinate at the bottom right of the selection Char UP_RIGHT_Y_COORDI

For example, as illustrated in FIG. 7A, the selection area may refer to the entire map screen displayed on the corresponding selection screen when the measurer selects a feature adjacent to the measurement pipe. Accordingly, the central coordinates of the selected area are the geographical coordinates of the center of the entire map displayed on the screen provided to the measurer, the coordinates of the upper left corner are provided to the measurer, and the geographical coordinates of the upper left corner of the screen are provided to the measurer. It can indicate the geographical coordinates of the lower right corner of the screen. By managing the geographical coordinates of the selected point, it may be helpful to request an update of the map information to the future geographic information system, or to know the exact geographic location of the measured distance. The geographic coordinates may be provided to the terminal device from the geographic information system as geographic absolute coordinates.

When the selection information for the measurement point is not directly managed as described above, the information for the selection area may be managed while the information of the measurement points selected by the user in the selection area may be inferred.

After all the measurement points are selected through the output means (for example, a display) of the terminal device 200, measurement data is collected through the measurement device 100 and the imaging means 211.

The measurement device 100 obtains the linear distance and angle values of the measurement points, and obtains vertical and horizontal distances based thereon to transmit vertical and horizontal distance data as described with reference to Table 1 to the terminal device 200. Meanwhile, as illustrated in FIG. 7C, image data for a measurement point may be obtained through the imaging means 211 provided in the terminal device 200.

Accordingly, the data collection unit 240 receives vertical and horizontal distance data from the measurement device 100 with respect to the measurement point, and may store and store image data in association. However, as for the vertical and horizontal distance data, the distance information required for the geo data must be calculated through calculation. As shown in Table 3, image data can be separately managed.

Explanation Type Field Video information name VarChar2 ORIG_ATTACH_FILE_NM Attachment ID Number ATTACH_FILE_ID Drawing sketch history Blob BLUEPRINT_DRAFT_DESC

The attachment file ID may include information about the measurement point. That is, the terminal device 200 recognizes which measurement point is the video information and gives an identifier. The drawing sketch history may include image information for the selected area.

The geo data calculation unit 250 calculates a value required for the geo data based on the data collected by the data collection unit 240. 7D by calculating the horizontal distance between one measurement point p1 of the facility T and two measurement points p2 and p3 of the terrain B based on Equation 1 and Equation 2 as described above. The results as shown in can be displayed to the measurer.

After calculating the horizontal distance between the facility T and the topography in this way, the terminal device 200 may calculate the depth of the facility T through measurement. However, the order of calculating the horizontal distance and the depth is not limited to this, and may be performed simultaneously or the depth may be calculated first.

8 is a conceptual diagram for explaining a method for obtaining a depth value in the present invention, and FIGS. 9A and 9B are diagrams illustrating an exemplary screen for obtaining a depth value through a terminal device.

Referring to FIG. 8, the facility T, the virtual position L, from the virtual position L where the measurer standing on the ground surface G is holding the terminal device 200 to which the measurement device 100 is attached. The vertical distance between the ground surfaces G is measured. As described above with reference to FIGS. 6A and 6B, the imaginary position L may correspond to a position where the measurer is holding the measurement device 100.

Since the vertical and horizontal distances (v(L~p1), h(L~p1)) have already been obtained through the measurement of one measuring point (p1) of the facility T, the measuring person has one measuring point of the ground surface G The measurement is performed through the measuring device 100 with respect to (p4). Since the measurement method is the same as described above, it is possible to measure a straight line distance and an angle with respect to one measuring point p4 of the ground surface G through the measuring device 100. Simultaneously with this measurement, as shown in Fig. 9A, image data of the ground surface can also be obtained.

When the measurement of one measuring point p4 on the surface is completed, the measuring device 100 horizontally and vertically distances h(L to p4) and v (L to p4) from one measuring point p4 on the surface G )). Of course, according to an embodiment, since the horizontal distance information with one measurement point p4 on the surface is not required, the measurement device 100 may calculate only the vertical distance v(L to p4).

Accordingly, as shown in FIG. 8, the vertical distance (v(L to p1)) of one measurement point p1 of the facility T and the vertical distance (v() of one measurement point p4 of the ground surface G are shown. L~p4)) can be obtained, and the depth (H) of the facility (T) can be calculated through a simple method.

Measurement data for the ground surface G may also be processed into a data structure as shown in Table 1 and provided to the data collection unit 240 of the terminal device 200.

In conclusion, the data collection unit 240 is a horizontal and vertical distance through the measurement of a plurality of measurement points (p1, p2, p3, p4) of the facility (T), the topography (B), and the surface (G) After receiving all the data shown in Table 1 for each of the measurement points in accordance with the acquisition, it can be converted to the calculation data shown in Table 4.

The X coordinates and Y coordinates of the facility T, p2 measurement point, and p3 measurement point can be obtained based on the actual geographic X coordinate and Y coordinate of the selected area, which are described with reference to Table 2, respectively. The information of the last three rows of Table 5 is displayed as horizontal distance information '7.32' and '9.64' as shown in FIG. 9B, and may be displayed through the terminal device 200 at a depth of facility '1.24'. In addition, the locations where each of these are displayed may be based on the geographic coordinates obtained according to the previously selected region.

As described above, when geo-data including horizontal distance data between a facility and terrain and depth data of a facility is generated, a measurer may request a modification request from the server 300 through the terminal device 200. Geo data may be provided to the server 300 through the communication unit 220 of the terminal device 200 to update the geo data of the corresponding facility.

According to an embodiment, the geo data may include image data obtained for a measurement point through the imaging means 211 of the terminal device 200. For example, the geo data may be included as characteristic information for a facility, but image data for a plurality of measurement points may be obtained for one facility, and a plurality of image data may be linked for one facility It may also be transmitted to the server 300 as geo data.

The server 300 may identify the related facility T or the terrain B based on the received geo data and change the characteristic information of the identified facility T or the terrain B.
