Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a GPS (Global
The present invention relates to a curtain information registration system for registering curtain information in a reference point surveying operation using a positioning system (global positioning system), and a recording medium therefor.

[0002]

2. Description of the Related Art On-site observation work in GPS surveying is as follows.
To install a plurality of GPS antennas and receivers at a plurality of measurement points (given points whose coordinate values are already known and new points whose coordinate values are to be obtained), and receive radio waves transmitted from artificial satellites. . Before and after the GPS observation at such a site, observation planning work and result creation work are performed indoors using software.

[0003] In the case of GPS surveying, for example, before observation at the site, information taking into account the movement of the satellite is obtained.
As shown in FIG. 1, one observation (one session) performed in the same time zone can receive radio waves transmitted from four or more satellites located at an elevation angle of 15 degrees or more for a certain period of time. It is necessary to secure a time zone. In this case, the satellite arrangement state (PDOP) also needs to be dispersed to some extent, and the "curtain" must be sufficiently considered.

[0004] The "curtain" is an obstacle that exists between the artificial satellite and the GPS antenna and blocks radio waves transmitted from the satellite, and mainly corresponds to structures such as buildings, forests, and the like. In Japan, many points are located in mountainous areas, and there are many curtains around the station, as shown in Fig. 2, which block satellite signals. It is necessary to investigate and calculate the observable time zone satisfying the above conditions.

That is, in the GPS survey, it is necessary to confirm the location of the curtain in advance, and to perform observation in consideration of a time zone in which satellite radio waves are not cut off. However,
In the conventional method, as shown in FIG. 3, the curtain shape (azimuth angle, altitude angle) observed by a total station or the like is manually input, which is very inefficient. Further, when observing the same point at another time, it is necessary to re-enter the curtain shape or, if the previous curtain shape does not remain, go to the site and observe again using the total station. Therefore, in such a manual input method,
Not only is the efficiency inefficient, but also the curtain information once registered cannot be separately reused for other work.

[0006]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention incorporates automation into the registration of curtain information that assists on-site observation in GPS surveying, thereby shortening the time without requiring high expertise. To provide a curtain information registration system capable of registering curtain information efficiently in a short time and reusing the created curtain information, thereby contributing to a smooth progress of on-site observation work. With the goal.

[0007]

According to the main features of the present invention, means for acquiring obstruction observation data at an observing scheduled point, and generating curtain information of the observing scheduled point based on the acquired obstruction observing data are provided. And a curtain information registration system including means for storing the generated curtain information in correspondence with the scheduled observation point information, and
Acquiring the obstacle observation data at the observation point, generating the curtain information of the observation point based on the acquired obstacle observation data, and converting the generated curtain information to the observation point information. And a storage medium for registering curtain information, which stores a program comprising the steps of:

In the present invention, the obstacle observation data is survey data based on surveying at the scheduled observation point or image data based on photographing at the scheduled observation point.

According to the features of the present invention,
Obtain obstacle observation data at the observation point, generate curtain information of the observation point based on the acquired obstacle observation data, and store the generated curtain information corresponding to the observation point information. So that
By introducing automation into the registration of curtain information at the GPS observation planning stage, curtain information can be efficiently created, and the created curtain information can be reused. If the observation data is stored, the observation data can be reused for the same observation point.

[0010] In the present invention, as the obstacle observation data,
Survey data based on the survey at the scheduled observation point is used. That is, the survey data is obtained from a file attached to a surveying device or system such as a total station in a data format of a common specification called “APA data”. Then, such survey data is automatically developed on the curtain registration screen with each observation point of the direction angle and the elevation angle as a shape change point of each curtain. Therefore, only by importing survey data from a surveying instrument or a file, curtain information is automatically generated, and the curtain information can be registered efficiently.

In the present invention, image data based on photographing at an observation scheduled point is used as the obstacle observation data. For example, digital sky image data (bitmap) obtained by photographing a sky image at a scheduled observation point using a digital camera or the like with a fisheye lens is fetched from a camera or a bitmap file and displayed on a curtain registration screen, and the image data is displayed. In the background, curtain information can be registered by pick input without being aware of the direction angle and altitude angle. Therefore, the curtain information registration work can be performed efficiently in a short time.

[Overview of GPS Survey Operation Process]
The reference point surveying operation using GPS (GPS surveying) can be roughly classified into the following three items: (1) observation planning operation before observation, (2) actual observation operation on site, and (3) observation data. Work to create results (various calculations, etc.).

In GPS surveying, the observation work performed on site is to install a plurality of GPS antennas and receivers at a plurality of measurement points and receive radio waves transmitted from artificial satellites. Here, the measuring point includes a given point whose coordinate value is already known and a new point whose coordinate value is to be obtained, and the number of GPS antennas and receivers that can be simultaneously arranged at each measuring point is basically Is determined by the number of observers. G like this
Since there are several rules for PS observation, it is necessary to confirm whether these rules are satisfied in the observation planning work before observation in (1). For example,
In the observation planning work of (1), it is necessary to pay attention to the following points.

In one session, as described above, radio waves transmitted from four or more satellites located at an elevation angle of 15 degrees or more can be received for a certain period of time, and the satellite arrangement state (PDOP) is changed. There is a condition that it must be dispersed to some extent. In addition, it is necessary to investigate the shape of the curtain (obstacle) in advance and calculate an observable time zone satisfying this condition.

Before on-site observation, it is necessary to establish a plurality of sessions according to the number of measurement points to be observed and the number of GPS antenna receivers that can be used simultaneously. In this case, at the time of inspection calculation for producing results after on-site observation, a three-dimensional vector (d
In consideration of obtaining the difference and the difference between (x, dy, dz), a session plan that satisfies a predetermined condition such as observing at least one side of each session overlapping with the side of another session is required. There must be. Further, it is desirable that an arrangement schedule of these GPS receivers be drafted in advance.

In the result creation stage, a three-dimensional net average calculation is performed using the three-dimensional vector group and the given point coordinates in order to obtain a new point coordinate which is the final result. In the figure, if there is a “missing” of a vector for which the three-dimensional network average cannot be calculated, inconvenience will occur in the calculation of the final result. It is necessary to keep.

After the on-site observation, the work of creating the result of (3) is performed using the data acquired by receiving the satellite radio wave.
Some rules also occur in each of these operations.
For example, in the baseline analysis for calculating a three-dimensional vector, the order of calculations such as which measurement point in which session should be started, or the start point / end point of each vector, and calculation of a certain vector or session There are unique rules such as sending calculation results such as passing results (coordinate values) to adjacent vectors and sessions and calculating.

According to one embodiment of the present invention, in the operation (1) described above, various kinds of plan information are automatically registered or generated based on the observation plan.
Not only the on-site observation work in (2), but also the work of creating results such as baseline analysis and three-dimensional net average calculation in (3) (baseline analysis, three-dimensional net average calculation, etc.), and automatic calculation of various work rules Can be realized.
FIG. 5 is a diagram showing main steps of a GPS observation support system including a curtain information registration system according to one embodiment of the present invention. The steps of this GPS observation support system are:
Large, observation plan stage ST1, on-site observation stage S
It can be divided into T2 and result creation stage ST3,
Each stage corresponds to each of the operations (1) to (3).

Referring briefly to FIG. 4, the observation system according to one embodiment of the present invention includes an observation planning stage S
At T1, curtain information is generated based on obstacle observation data, and curtain information and observation point information (DB1)
, Generating average map information (DB2) according to a predetermined rule based on the observation condition information, observation point information and average map information, according to a predetermined rule.
And generates GPS receiver deployment schedule information according to a predetermined rule based on the GPS receiver usage conditions and session plan information, and generates the schedule information (DB4).
To the GPS receiver. In the result creation stage ST3, various plan information (DB1 to DB4) and GPS
Baseline analysis calculation is performed according to a predetermined rule based on the receiver observation data (ST2).

In the first observation planning stage ST1, before observation at the site, observation scheduled points (stations) are determined, attribute data (point attributes) at each station, average map data representing connections between the points, and the same. Session configuration data representing the configuration of a session, which is one observation range performed in a time zone, and receiver location data representing the location of a GPS receiver assigned to each measurement point for each session are created. Attribute database DB1 and average map database DB provided in different storage areas (or storage media)
2. Stored and registered in the session database DB3 and the receiver arrangement database DB4.

In the next on-site observation stage ST2,
By referring to various data registered in these databases DB1, DB3, and DB4, actual observation work is sequentially performed according to a work plan indicated by the information content. Then, the result creation work is started in the result creation stage ST3, and the observation data acquired in the stage ST2 is processed and various calculations are performed while referring to the session-related data registered in the databases DB1 to DB3.

FIGS. 6 and 7 are functional block diagrams showing schematic functions of a GPS observation support system including a curtain information registration system according to one embodiment of the present invention. G
The field observation work in the PS survey, as described above, multiple GPS antennas and receivers are installed at multiple measurement points,
The purpose is to receive radio waves transmitted from artificial satellites. Here, the measuring point includes a given point whose coordinate value is already known and a new point whose coordinate value is to be obtained, and the number of GPS antennas and receivers that can be simultaneously arranged at each measuring point is basically Is determined by the number of observers. As described above, since there are several rules in GPS observation, it is necessary to confirm whether or not these rules are satisfied in the observation planning stage before observation.

Therefore, in the observation planning stage ST1, the host computer 1 is first used to execute a scheduled GPS observation as shown in a functional block B1.
Set observation conditions such as the number of the receiver owned by the observer and the scheduled date and time of observation. In addition, as shown in a functional block B2, the coordinate data (point data) of the planned measurement point is read by a method such as reading data of a point planned as a measurement point for GPS observation using the tablet 12 or the like. Generate. The printer 13 can print out a “coordinate conversion calculation” using the point data. The coordinate conversion calculation includes, for example, a coordinate system (Vessel) unique to Japan.
And a coordinate value converted between a coordinate system (WGS84) common to the world.

The coordinate data (point data) of these scheduled points
Is added with a point attribute including an eccentric attribute in a functional block B3, and is registered in the point attribute database DB1 of the external storage device 4. Here, the point attribute is an attribute when performing various calculations, for example, “base station” for performing baseline analysis, “BLH fixed”, “known point”, “new point” for performing assumed network calculation. , "Node" and "eccentric point" for performing eccentricity calculation.

As described above, 1 performed in the same time zone
In one observation (one session), radio waves from four or more satellites can be received for a certain period of time in consideration of the movement of artificial satellites, and the satellite arrangement (PDOP) is dispersed to some extent. It is necessary to secure the time zone in which it is. In addition, in Japan, many points are located in mountainous areas, and there are many curtains around the measuring point that block satellite radio waves. It is necessary to calculate a suitable time zone. If the observable time zone cannot be calculated from the curtain information, eccentric observation and eccentricity calculation are required.

Therefore, in this system, before the on-site observation, the total station 10 is used to generate curtain (obstacle shape) information and calculate eccentricity, and the horizontal angle and altitude angle ( Obtain TS data over 360 degrees of obstacle data) and the horizontal angle and altitude angle (TS eccentricity observation data) between two measurement points. Or,
For generating curtain information, the digital camera 11 is used to acquire sky image data in a 360-degree field of view at each measurement point. In this case, the digital camera 11
It is preferable to use a digital camera using a fish-eye lens that can capture a sky image with a 60-degree field of view. In the functional block B4, the curtain information is automatically generated from the TS observation data or the image data acquired before the observation, and registered in the curtain information storage area of the external storage device 4. The "curtain information" can be printed out from the printer 13.

After the on-site observation of the GPS, the three-dimensional vector group is expressed using the three-dimensional vector group and the given point coordinates in order to obtain a new point coordinate which is the final result. If the “average diagram” includes “missing” of a vector for which the three-dimensional network average cannot be calculated, inconvenience occurs in calculating the final result. Therefore, it is necessary to prepare an average map without such omissions before the on-site observation, and to make a session plan based on the average map. When making a session plan, a three-dimensional vector (dx,
Since it is necessary to take into account the calculation of the difference and the difference between the dy, dz), correct session settings must be set so that at least one side of each session can be observed overlapping with the other session. Plan ahead.

In the function block B5, such average map data and session plan information are transferred to the function blocks B1 to B5.
It is automatically generated based on the observation condition data, point data, point attribute data, and curtain information obtained in B4, and is stored and registered in the average map database DB2 and the session database DB3 of the external storage device 4. The session plan information generated here includes a session shape, a detailed scheduled observation date and time, and is sent from the printer 13 to various session plan graphs in a graph format (for example, “number of satellites and PDO”).
P "," elevation angle "," azimuth "," number of satellites "," satellite ",
"Skyplot", "PDOP", "HDOP",
“VDOP”, “GDOP”, “TDOP”, etc.).

Depending on the number of stations to be observed and the number of GPS receivers that can be used at the same time, as a consideration before the GPS site observation, a plurality of session
It is necessary to plan the arrangement schedule of the S antenna receiver in advance. Therefore, in the function block B6, G
Based on the observation conditions such as the PS receiver number and the session plan information, schedule information indicating the arrangement schedule of the GPS receiver is automatically generated, and stored and registered in the receiver database DB4 of the external storage device 4. This schedule information includes a point attribute and a session [DB1, DB3].
And the printer 13 can print out a "schedule table" or the like based on the schedule information.

In the next on-site observation stage ST2,
The schedule information [DB obtained in the function block B6
4] is automatically registered in the GPS device 1, and the GPS device 1 is arranged and operated according to the registered schedule information.
At each station, observation data is acquired by receiving satellite radio waves (type of radio waves from artificial satellites = L1 band, L2 band).

After the site observation, the result creation stage ST
In step 3, various operations for creating results are performed using observation data acquired by receiving satellite radio waves. Some rules also occur in each of these operations. For example, in the baseline analysis for calculating a three-dimensional vector, the order of calculation such as what measurement point in which session should be started, or what the start point / end point should be in each vector, and calculation of a certain vector or session There are unique rules such as sending calculation results such as passing results (coordinate values) to adjacent vectors and sessions and calculating.

For this reason, in the result creation stage ST3,
In addition to handing over the information registered and generated based on the observation plan to the on-site observation work, as shown in functional blocks B7 to B10, results creation work such as baseline analysis and three-dimensional net average calculation (baseline analysis, three-dimensional Network average calculation, etc.)
A mechanism for automatically calculating various work rules is also realized.

That is, in the function block B7,
Observation data from the GPS device 9, point attribute data [DB1] from the function block B3, average map data and session information (session plan information) from the function block B5
Baseline analysis calculation is automatically performed based on [DB2, DB3]. From the printer 13, the observation data and the baseline analysis results (coordinates) describing the observed raw information [point number (No), antenna height, observed satellite status, etc.) are obtained from the observation data and the baseline analysis results. Various drawings can be printed out in addition to the “observation book” in which values, vectors, etc. are described.

In the function block B8, the function block B7
Inspection calculation is automatically performed based on the baseline analysis result obtained in step (1), and an “inspection calculation book” is output from the printer 13 by the inspection calculation. In the function block B9, the results of the baseline analysis and the point attributes from the function blocks B7 and B2,
In addition, an eccentricity calculation is performed based on the TS eccentricity observation data regarding the horizontal angle and the altitude angle between the two measurement points obtained by the eccentricity observation of the total station 10, and the eccentricity calculation book and the eccentricity calculation book are printed by the printer. 13 is output.

In the function block B10, the function block B
The three-dimensional network average calculation is performed based on the base line analysis results and the point attributes from 7 and B2, and further, the functional block B11 performs the quality management calculation based on the result of the three-dimensional network average calculation. By the three-dimensional network average calculation and the quality control calculation in the function blocks B10 and B11, the "three-dimensional network average calculation report", "result table", "quality control table", and "quality control calculation book" are respectively sent from the printer 13. Is output.

FIGS. 8 and 9 are flowcharts showing the main processing executed in the GPS observation support system including the curtain information registration system according to one embodiment of the present invention. In the observation plan stage ST1 (indoor work), first, in step M1, GPS site information (such as a work room) is registered in advance, and the next step M1 is performed.
In step 2, information (such as coordinate data) of a point scheduled for GPS observation is registered in the point attribute database DB1 as observation point data.

In step M3, curtain information automatically generated from the TS observation data or image data from the total station 10 or the digital camera 11 is registered in the curtain information storage area of the external storage device 4.
Also, in step M4, a session plan is executed according to a predetermined rule, and average map data is created based on the arrangement state and point attributes of the points to be observed. In consideration of this, the shape and observation date and time of all sessions are calculated, and session plan information is automatically created.

After the creation of the average chart data and the session plan information in step M4, a schedule creation operation is performed in step M5. In this schedule creation work, how to arrange the limited number of GPS receivers (GPS device 1) is determined in accordance with the shape of the session, and automatic setting is performed for each receiver. Observation information is set. By this operation, schedule information for instructing the arrangement and operation of the GPS receiver (GPS device 1) is automatically created.

Next, in the on-site observation stage ST2 (outdoor work), in step M6, schedule information is automatically registered in the GPS device 1, and the GPS device 1 is arranged at each measurement point according to the registered schedule information. Perform GPS in-situ observations. In this case, it is determined in step M7 whether eccentricity observation is necessary. If it is determined whether eccentricity observation is necessary, eccentricity observation is performed by the total station (TS) 10 in step M8. In this eccentric observation, a place where it is impossible to acquire radio waves from a satellite is called an “eccentric point”, and a temporary measurement point near it is called an “eccentric point”.
And GPS observation is performed at this eccentric point. In this case, the positional relationship (horizontal angle and altitude angle) between the eccentricity calculation point and the eccentricity point is observed in advance by TS (total station) eccentricity observation.

After that, in the result creation stage ST3 (indoor work), in step M9, the on-site observation stage ST
The observation data acquired in step 2 is fetched, and step M10
Perform baseline analysis at. In the next step M11, an automatic inspection calculation is performed based on the baseline analysis results, and further, the baseline analysis results and point attributes, and the total station 10
Based on the TS eccentricity observation data (horizontal angle and altitude angle between two points) obtained by the eccentricity observation, the eccentricity calculation for replacing the vector from the eccentricity finding point is performed.

Next, in step M12, a three-dimensional net average calculation is performed based on the results of the baseline analysis and the point attributes. In this three-dimensional net average calculation, a new point coordinate is calculated based on a vector between each point calculated by the baseline analysis (M10) and a coordinate value of each point, and a new point coordinate is calculated. There are a hypothetical net average calculation in which values are fixed and a practical net average calculation in which all given points are fixed and calculated. further,
In step M13, an accuracy management calculation for verifying the accuracy of the given point is performed using the existing coordinate values of each given point and the result calculated by the three-dimensional net average calculation.

Here, if a good result is not obtained in each of the processes in steps M10 to M13 (NG), the process returns to step M10 and the processes in steps M10 to M13 are executed again. If a good result is not obtained, it is also possible to return to step M12 and start over from the three-dimensional network average calculation. If a good result is not obtained in each of the processes of Steps M10 to M13 (NG), the process may return to Step M3 of the observation planning stage ST1 and start over from the planning stage as necessary.

When the processing in step M13 is completed, in step M14, the three-dimensional network average calculation (M1
A form describing the coordinate values calculated in 2) is output from the printer 13 as a “result table”, and the process proceeds to step M15.
In the above, various drawings and various calculation documents are printed out based on various result data obtained by the result creating operation.

As described above, in the GPS observation support system according to this embodiment, in addition to the registration of the curtain information, the correct average map is set in advance for the on-site observation work.
A session in consideration of the set average map is planned, and a limited number of GPS antennas and receivers can be efficiently arranged at a required time and at a required measuring point in accordance with the planned session. .

Further, after the site observation, when performing the work of creating the result using the data acquired by receiving the satellite radio wave,
For example, in the baseline analysis, a 3D vector is calculated based on a unique calculation procedure that originally requires specialized knowledge, such as a session to start calculation and measurement points, and rules for setting start and end points for each vector. However, the GPS observation support system according to this embodiment implements a mechanism for calculating automatically, and works efficiently without requiring highly specialized human resources (experts). Can be.

[Curtain information registration system] FIG.
It is a functional block diagram showing a schematic function in a curtain information registration stage according to an embodiment of the present invention,
This corresponds to the function of the function block B4 in the function block diagrams of the entire system shown in FIGS. In short, referring to FIG. 10, the curtain information registration system according to the embodiment of the present invention is configured so that the APA survey data from the file or the total station 10, or the sky image data from the digital camera 11 or the bitmap file, Captured as object observation data (CB1, C
B2, CB4), based on the acquired obstacle observation data, curtain information of the observation scheduled point is automatically generated. In the case of APA survey data, each observation point of the direction angle and the altitude angle is automatically developed on the curtain registration screen as a shape change point of each curtain. In the case of sky image data, it is displayed on a curtain registration screen, and curtain information is registered by pick input with the image data as a background.

In one embodiment of the present invention, the horizontal angle and the altitude angle of a predetermined point are obtained by surveying, and the already-observed data (the survey data in the APA format) in a format common to each user is transmitted to a communication interface (shown in FIG. ), And is stored and registered in a file provided in a predetermined area (medium) of the external storage device 4 of the host computer 1 in advance. When the survey data of the scheduled observation point (measurement point) is registered in this file, the already-observed data of the planned point is directly read from this file as shown in a function block CB1.

Alternatively, TS observation data (APA format) relating to the horizontal angle and the altitude angle of the observation point is acquired by the total station 10 and, as indicated by the function block CB2, the total station 10
S observation data is directly received and taken into the system.

The already-observed data or the TS observation data in the predetermined format (APA format) obtained in the functional blocks CB1 and CB2 are used in the functional block CB3.
Observation point of the already observed data or total station 10
By setting the installation point as a GPS observation point (measurement point) and developing each observation point as a shape change point of each curtain, it is automatically developed as a curtain shape. Therefore, since the curtain information is generated only by the operator reading the APA data, the curtain information creation operation can be performed very efficiently. Note that the function block CB3 can be edited as needed. In addition, even when the same point is separately observed, the data in the APA format can be reused.

In one embodiment of the present invention, a curtain registration function on image data can be provided in addition to using already observed data or TS observation data in APA format. For example, a digital camera 1 with a fisheye lens
For each observation point (measurement point), 36
Sky image data in a bitmap format (for example, BMP) extending over 0 degrees is acquired, and a curtain shape can be created using this image data. In this case, in the functional block CB4, digital photographing data of the sky image is fetched from the digital camera 11 or the bitmap file, and displayed on the curtain registration screen of the display 6.

Next, as in the functional blocks CB5 to CB7, the image scale is changed and the azimuth (angle) is changed as necessary.
Is changed or the image is inverted vertically and horizontally. That is, since the image data is image data captured by a fisheye lens, various operations can be performed on the image. For example, in order to finely adjust a correct direction, rotation of an azimuth axis with respect to the image is possible. In order to replace the line of sight with a correct line of sight, it is also possible to flip the image vertically and horizontally.

After performing the required image operations as described above,
As in the function block CB8, on the image data,
By picking a curtain (obstacle) with image data as a background without being aware of the direction angle or altitude angle, curtain information in a bitmap format is created and stored / registered in a predetermined storage area of the external storage device 4. can do. Further, by storing the curtain information in the bitmap format, it becomes possible to immediately cope with a case where it is necessary to separately observe the same point.

FIGS. 11 to 14 are flowcharts showing the curtain information registration processing executed in the curtain information registration system according to one embodiment of the present invention. In this curtain information registration process, in the first step C1, "A
"PA" registration, "Editor" registration or "Image" (BMP)
The process is started by selecting one of the registration methods from the registration, and a curtain information registration screen is displayed on the display 6. Here, if "editor" registration (editor) is selected in step C1, step C2
To "C4" registration processing is executed, and "APA"
If registration (APA) is selected, steps C11 to C20
"APA" registration processing (FIG. 12) is executed, and "image"
If registration (BMP) is selected, steps C31 to C48
Is performed (FIG. 13 and FIG. 14).

["Editor" registration process] For the previously observed data or TS observation data in the APA format,
If "editor" registration is selected in step C1, curtain information registration work is performed on the editor using, for example, a curtain registration program of Trimble (Trimble). For example, while viewing the output paper of the TS observation data, Azimuth and elevation can be manually entered. That is,
When the station number is selected in step C2 and the editor is started in step C3, in step C4 curtain information relating to the station of the registered number is entered in accordance with a predetermined editor program (for example, the above-described trimble program). It is created and stored / registered in a predetermined storage area of the external storage device 4.

Then, in step C5, it is determined whether or not curtain information is registered for another station number data or another kind of observation data, and curtain information is registered for another station number data or another kind of data. If (YES), the process returns to step C2 or step C1, and if another data is not registered (NO),
This curtain information registration processing ends.

["APA" registration process] When "APA" registration is selected in step C1 for the already-observed data or TS observation data in the APA format, the station number is selected in step C11 (FIG. 12). In step C12, a method of acquiring observation data is determined. Here, in the case of already-observed data, the process proceeds to step C13,
The external storage device 4 is driven to select an observation data file. If the observation data file is stored in the total station 10, the process proceeds to step C14 to perform communication setting (RS232C) with the total station 10. In the following step C15, predetermined observation data registered in the file or new observation data from the total station 10 is loaded into the system, and the read observation data is displayed on the curtain registration screen of the display 6. Curtain information is generated by automatically developing the curtain shape using the next observation data measurement point as the curtain shape change point.

Next, in step C16, step C
Determine whether to edit the curtain shape obtained in step 15,
In the case of editing, the process proceeds to step C17, and the editing mode is further determined.
To perform single editing, and in the case of continuous editing, step C19.
After performing continuous editing, the process proceeds to step C20. Also,
If it is determined in step C16 that the curtain shape is not to be edited, the process immediately proceeds to step C20.

In step C20, curtain information representing the curtain shape of the measurement point is stored and registered in a predetermined storage area of the external storage device 4. In the next step C21 (FIG. 11), another number or another type of data is stored. It is determined whether or not (curtain information) is to be registered. If another number or another type of data is to be registered (YES), step C2 is performed.
Returning to step 1 or step C1, if another data is not to be registered (NO), the curtain information registration processing is terminated.

[“Image” Registration Process] Digital Camera 11
When the sky image data of 360 degrees from is read and the "image" registration is selected in step C1, the station number is selected in step C31 (FIG. 13), and in the next step C32, the The corresponding image data is selected and displayed on the curtain registration screen of the display 6. In the next step C33, it is determined whether or not the image data has a scale. If there is a scale, the image data is converted to a standard scale in step C34. If not, the current scale is maintained (step C35). In a succeeding step C36, it is determined whether or not the azimuth axis (angle) is changed in the image data. If there is a change in the azimuth axis (angle), the image data is converted into a standard azimuth axis (angle) in step C37. If not, the current azimuth axis (angle) is maintained (step C
38).

Further, in step C39, it is determined whether or not the image data has upside down. If there is upside down, the image data is converted to the standard state in step C40. If not, the current state is maintained (step C39). C41). Subsequently, in step C42 (FIG. 14), it is determined whether or not the image data has left / right inversion. If there is left / right inversion, the image data is converted to the standard state in step C43; otherwise, the current state is maintained. (Step C44).

As described above, when the image data is reset to the standard state, the editing mode of the image data is selected in step C45. In the case of the continuous mode, the continuous mode editing is performed in step C46. Is Step C4
In step 7, single mode editing is performed. In the editing operation in any of steps C46 and C47, curtain information in a bitmap format can be created by picking and inputting a curtain (obstacle) with the image data as a background.
Then, in step C48, the created curtain information is stored and registered in a predetermined storage area of the external storage device 4.

In the next step C49 (FIG. 11),
It is determined whether or not to register another number or another type of data (curtain information). If another number or another type of data is to be registered (YES), the process returns to step C31 or step C1 to register another data. If not (NO), the curtain information registration process ends.

FIG. 15 (a) registers an APA observation data file and APA observation data from the total station 10. FIG. 15B shows an example in which image data from the digital camera 11 is registered as an “image”.

As described above, according to the present invention, obstacle observation data at an observation scheduled point is acquired,
Since it is configured to generate the curtain information of the scheduled observation point based on the acquired obstacle observation data and to store the generated curtain information in correspondence with the scheduled observation point information, the curtain information is stored in the GPS observation planning stage. Automation is introduced into the registration of curtain information, so that curtain information can be efficiently created. In addition, observation data and created curtain information can be stored and reused for the same observation point.

In the present invention, the survey data based on the survey at the observation scheduled point is used as the obstacle observation data. That is, the survey data is obtained from a file attached to a surveying device or system such as a total station in a data format of a common specification called “APA data”. Then, such survey data is automatically developed on the curtain registration screen with each observation point of the direction angle and the elevation angle as a shape change point of each curtain. Therefore, only by importing survey data from a surveying instrument or a file, curtain information is automatically generated, and the curtain information can be registered efficiently.

In the present invention, image data based on photographing at an observation scheduled point is used as the obstacle observation data. For example, image data (bitmap) obtained by photographing a sky image at a scheduled observation point with a digital camera equipped with a fisheye lens from a camera or a bitmap file is displayed on the curtain registration screen, and the image data is set as a background. The curtain information can be registered by pick input without being aware of the direction angle and altitude angle. Therefore, the curtain information registration work can be performed efficiently in a short time.
