Description

  The present invention relates to a surveying information processing apparatus, and more particularly, a surveying information processing that enables a surveying operator to immediately start measuring the building accuracy indicated by the CAD after receiving the object-oriented CAD. Relates to the device.

  Conventionally, in building design work, each member of the building from the perspective of whether the building can withstand earthquakes, etc., and the architect (or design designer) who is responsible for determining the building shape and finish specifications, etc. A structural designer who is in charge of determining the cross-section, the amount of reinforcing bars, etc. jointly performs design work.

  Here, each person in charge of design works using a computer. However, each person in charge of building individually inputs building information into the computer even though the work is designed for the same building. is the current situation.

  In other words, a building designer gives a building drawing input by CAD (Computer Aided Design) for building production (design design) to the structural designer as paper or electronic data, and the structural designer revises the system for structural design. Currently, building information is entered in Therefore, despite the fact that the architect has entered the building information into the computer with much effort, the structural designer has to enter the same information in a different form. It was.

  On the other hand, in recent years, object-oriented CAD, that is, software called object CAD has appeared mainly in the field of architectural design, and it is not a substitute for a simple drafter (drafting machine) like conventional CAD. It is becoming possible to recognize each member constituting the. That is, in the case of a conventional CAD, a computer can recognize only as a collection of lines, although it can be recognized as a pillar, a wall or the like by looking at a drawing created by CAD. On the other hand, in the object CAD, there is a big difference that the computer recognizes the column as a column and the beam as a beam. On the other hand, in the field of structural design, the software originally recognizes such building members individually.

  However, it is still difficult to exchange data between the information by the object CAD input by the building designer and the information for structural analysis input by the structural designer because of the difference in the viewpoint of the building.

  In order to solve these problems, some structural design systems implement a mechanism for assisting input by using a drawing created by CAD for architectural design as a background. If this mechanism is used, the input work of the structural designer can be reduced to some extent.

  However, even in this case, since it is still necessary to manually input the data, it is considered that a complicated operation for inputting the opening information of the wall and the slab is generated and the structural calculation is relatively less affected. It is a situation where the column shift (fine adjustment of the horizontal position) is not input. For this reason, the information for structural analysis that should be effectively used in the later process of the design is input only incompletely because the input work is complicated and cannot be effectively used. However, there are also situations where you need to enter building information in two or three layers.

  Thus, there is a demand for a technique for generating structure analysis information directly and automatically from CAD information for building design.

  As an invention for solving such a problem, Japanese Patent Application Laid-Open No. 2008-158793 (Patent Document 1) is CAD information for building design of a building to be generated for structural analysis information, and includes at least a plurality of columns or There is disclosed a building structural analysis information generation apparatus provided with input means for inputting architectural design CAD information including information indicating the shape, size, and position of a plurality of walls. The structural analysis information generation device further includes information indicating a core of the building based on information indicating the shape, size, and position of the plurality of columns or the plurality of walls included in the CAD information for architectural design. Basic information generating means for generating, and recording means for recording information indicating the core generated by the basic information generating means as information for structure analysis. Thereby, the information for structural analysis can be easily generated based on the CAD information for building design.

  Japanese Patent Laid-Open No. 2004-206193 (Patent Document 2) discloses a unified CAD for building component design / manufacturing information having a function of converting data related to building components input by a building designer into a data code used by the manufacturer. A system is disclosed. The building component design / production information unified CAD system further selects and inputs a building component type, and extracts a library corresponding to the selected building component type from a library group prepared in advance. Type selection input means and building component data input for selecting and inputting data relating to building components based on the extracted library and recording building component data as part of building design data used by the building designer Means. And the said building component member design and production information unification CAD system is based on the maker data table search means which searches a maker data table based on the inputted building component data, and the search result of the maker data table , Maker data conversion means for converting the building component data into a data code used by the maker to create maker data, and maker data output means for outputting the created maker data. This will reduce the cost of creating construction drawings for building components, reduce mistakes in creating production drawings, accurately control costs at the design stage, and reduce the risk of process delay by early determination of components within the business plan schedule. It can be done.

  Japanese Patent Laid-Open No. 2010-44447 (Patent Document 3) discloses a pre-cut CAD data conversion method for reading a building CAD file having a plurality of layers as a binary data file and generating a pre-cut map for pre-cut CAD. ing. In the pre-cut CAD data conversion method, the scale data of the drawing is described at a predetermined position of any layer of the architectural CAD file, and a pillar section having a square cross section and a predetermined square bar standard is recognized by the following procedure. In the first procedure, all the straight lines in the horizontal and vertical directions having a length in the range of a predetermined value with respect to one side length of the square of the column part are detected in all layers. Next, in the second procedure, one of the horizontal straight lines is selected, and a point at a distance of half or less of the vertical dimension and the horizontal dimension of the predetermined square bar standard is selected from each end coordinate of the horizontal straight line. Two straight lines in the vertical direction having either of the two end coordinates are extracted. Furthermore, in the third procedure, two straight lines whose straight line lengths are within the specified range with respect to the vertical dimension and the horizontal dimension of the predetermined square bar standard are extracted from the vertical straight lines extracted in the procedure. select. Then, in the fourth procedure, a point located at a distance equal to or less than half of the length of one side of the column cross-sectional square from the two vertical straight line coordinates selected in the above procedure has either of the straight line coordinates. The horizontal straight line is selected. As a result, by converting a file created by architectural CAD, which is not versatile in the construction industry, into pre-cut sketch data such as text format, which is versatile in the construction industry, an expensive predetermined type of architectural CAD It is possible to generate precut drawing data such as text format without using, and contribute to the cost reduction of the construction industry.

  By the way, the object CAD described above is frequently used for surveying work in building design work, for example, surveying work of building construction accuracy (building accuracy). The information required for the surveying work is completely different from the viewpoint of the building. Therefore, although the object CAD has a data structure capable of recognizing building members such as pillars and beams constituting the building, the surveyor still has to build the building by manual operation from the object CAD. There is a fact that information related to accuracy is extracted and survey information necessary for measuring the building accuracy is calculated (calculated).

  For example, when a surveyor receives an object CAD in a predetermined building from a structural designer or the like, the object CAD is first displayed on a predetermined drawing using CAD software such as DXF (Drawing Exchange Format). Or print on paper. Then, the surveying operator confirms the information on the building member such as a column and a beam from the object CAD, and survey information necessary for measuring the building accuracy of the building member, for example, the vertical dimension of the building member. And from the horizontal dimension, the position information (three-dimensional coordinate value) of the target seal installed on the building member is calculated manually. Further, the surveying operator inputs and stores the calculated information in a predetermined recording paper or a computer database. After this, the surveying operator can finally go to the building on the site in the object CAD and start measuring the building accuracy of the building.

  Here, there is a problem that it takes 1 day to 2 days at the shortest time from the confirmation work of the building member information in the object CAD to the calculation work of the survey information. Further, the above-described confirmation work and calculation work are troublesome, and there is a problem that a heavy burden is placed on the surveying operator. Further, since the confirmation work and calculation work basically involve human visual inspection and manual work, there is a problem that a confirmation mistake and a calculation mistake may occur. Of course, such problems cannot be solved by the inventions described in Patent Documents 1-3.

  Therefore, the present invention has been made to solve the above-mentioned problems, and has been made based on an epoch-making idea as a result of intensive studies by the inventor. That is, an object of the present invention is to provide a surveying information extracting apparatus that can immediately start building accuracy measurement of a building indicated by the CAD after receiving the object-oriented CAD.

  In order to solve the above-described problems and achieve the object, a survey information extraction apparatus according to the present invention is an object-oriented object CAD that associates member information related to a building with attribute information indicating an attribute of the member information. The surveying information extracting apparatus for extracting predetermined information from the above adopts the following configuration.

  That is, when a predetermined extraction instruction is input, the surveying information extraction device searches the member information of the object CAD for the building member information corresponding to the building member of the pillar or the beam constituting the building, and Extraction means for extracting attribute information of the searched building member information, and calculation means for calculating survey information necessary for measuring the building accuracy of the building member based on the extracted attribute information.

  Thereby, the attribute information of the building member information is automatically extracted from the object CAD, and the surveying information is automatically calculated. Therefore, the surveying operator receives the object CAD from a structural designer or the like. After that, without having to check the building member of the object CAD or calculate the surveying information by hand, which has been done in the past, you can immediately go to the site where the building exists and measure the accuracy of the building. (Surveying work) can be started.

  Further, the extraction means extracts position shape attribute information indicating the position and shape of the building member information in the building member from the searched attribute information of the building member information, and the calculating means includes the vertical direction of the building member. Dimension / lateral dimension, member length, survey core position information in the survey coordinate system, survey rotation angle in the survey coordinate system, sectional shape, layout floor, survey sticker position information indicating the position of the target seal in the survey coordinate system Can be configured to calculate survey information including

  Further, the extraction means, as the position shape attribute information, steel frame standard information indicating the standard of the steel frame constituting the building member, position information of the building member in the coordinate system of the object CAD, rotation position information, rotation angle, An offset indicating a conversion value for converting the coordinate system of the object CAD of the building member into a survey coordinate system is extracted. Then, the calculation means calculates a vertical dimension and a horizontal dimension of the building member and a cross-sectional shape perpendicular to the longitudinal direction of the building member based on the extracted steel frame standard information, and the extracted position information The surveying core position information indicating the core position of the building member is calculated from the offset, and the surveying rotation angle of the building member is calculated from the extracted rotation position information and the rotation angle or position information. Further, the cross-section of the building member is calculated according to the calculated vertical and horizontal dimensions of the building member, the cross-sectional shape, the survey core position information, the survey rotation angle, and the geometric relational expression. The measurement seal position information of the target seal installed on the outer surface of the shape can be calculated.

  In addition, the calculation means is based on a steel size table that associates predetermined steel standard information with the horizontal and vertical dimensions of the steel corresponding to the steel standard information, and the extracted steel standard information and the steel dimensions. By comparing with the steel frame standard information of the table and obtaining the horizontal dimension and the vertical dimension corresponding to the collated steel frame standard information, the horizontal dimension and the vertical dimension of the building member can be calculated.

  Further, the calculation means is based on a steel cross-sectional shape table that associates predetermined steel standard information with the cross-sectional shape information of the steel corresponding to the steel standard information, and the extracted steel standard information and the steel cross-sectional shape table. The cross-sectional shape of the building member can be calculated by collating with the steel frame standard information and obtaining cross-sectional shape information corresponding to the collated steel frame standard information.

  Further, the extracting means extracts the coordinate value in the Z-axis direction for each floor of the building in the object CAD and the start point coordinate value in the Z-axis direction corresponding to the coordinate value of the lower end portion of the building member in the building member information. To do. And the said calculation means compares the starting point coordinate value of the Z-axis direction of the said building member information, and the coordinate value of the Z-axis direction of a predetermined | prescribed floor in the order of the floor, and the Z-axis direction of the said building member information If the starting point coordinate value of the floor is greater than the coordinate value of the floor in the Z-axis direction, the starting point coordinate value of the building member information is compared with the coordinate value of the next floor in the Z-axis direction. When the starting point coordinate value in the Z-axis direction of the building member information is smaller than the coordinate value in the Z-axis direction of the floor, the floor can be calculated as an arrangement floor on which the building member is disposed. .

  Furthermore, it can comprise so that the calculated | required survey seal position information of the target seal | sticker may be preserve | saved at the survey information storage means in which the actual seal position information of the said target seal measured by the three-dimensional survey instrument is memorize | stored.

  According to the survey information extraction apparatus according to the present invention, after the survey operator receives the object-oriented CAD, it is possible to immediately start measuring the building accuracy indicated by the CAD.

  In the following, an embodiment of a surveying information extracting apparatus according to the present invention will be described with reference to the accompanying drawings to help understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  FIG. 1 is a schematic configuration diagram showing an example of a building accuracy management system including a surveying information extraction device according to the present invention.

  As shown in FIG. 1, the survey information extraction device 2 according to the present invention is, for example, one device that constitutes a building accuracy management system 1. In the building accuracy management system 1, in addition to the survey information extraction device 2, a server computer 3 installed in a company office, a portable terminal device 4 carried at a construction site, and installed at the construction site The three-dimensional surveying instrument 5 connected to the portable terminal device 4 by wire or wirelessly is basically configured. The survey information extraction device 2, the server computer 3, and the portable terminal device 4 are connected to each other via a network 6 such as the Internet in a wired or wireless manner.

  The surveying information extraction device 2 is a computer that is generally used. A storage unit that stores predetermined information, an operation unit such as a keyboard and a mouse, a reception unit that receives instructions from the operation unit, and a storage unit And a display unit for displaying a predetermined drawing (image) on the liquid crystal display based on the stored information.

  Further, when a predetermined extraction instruction for a predetermined object CAD is input from the operation unit to the surveying information extraction apparatus 2, the member information of the object CAD includes the column or beam constituting the building. An extraction unit that searches for building member information and extracts attribute information of the searched building member information, and survey information that is necessary when surveying the building accuracy of the column or beam based on the extracted attribute information And a calculating unit for calculating. The survey information extraction apparatus 2 further includes a storage unit that transmits the calculated survey information to the server computer 3 and stores it in the storage unit of the server computer 3 (described later).

  The server computer 3 is a computer that is generally used, and when receiving predetermined survey information from the survey information extraction device 2 via the network 6, the survey computer stores the survey information as a table, for example. Remember me. Further, when the server computer 3 receives input of predetermined building member information from the portable terminal device 4, the server computer 3 outputs surveying information corresponding to the building member information to the portable terminal device 4, and inputs predetermined building accuracy. If it receives, the said building precision is memorize | stored in the said memory | storage part. Further, when the server computer 3 receives input of predetermined building member information from the survey information extraction device 2 (or other terminal device), the server computer 3 sets the building accuracy corresponding to the building member information to the survey information extraction device 2 ( Or other terminal device). The storage unit of the server computer 3 serves as a database for building accuracy.

  The portable terminal device 4 is a portable computer that is generally used, and includes a display receiving unit such as a touch panel. Upon receiving input of predetermined building member information, the display receiving unit is connected to the server. Surveying information corresponding to the building member information is acquired from the storage unit of the computer 3 and displayed. Further, the display receiving unit starts measurement of the three-dimensional surveying instrument 5 when receiving a predetermined measurement instruction.

  The mobile terminal device 4 receives survey position information (three-dimensional coordinate values, X, Y, Z) from the three-dimensional survey instrument 5 after receiving survey information corresponding to predetermined building member information. And a calculation unit for calculating the building accuracy of the building member information. The calculated building accuracy of the building member information is stored in the storage unit of the server computer 3 (described later).

  The portable terminal device 4 may be a normal terminal device (for example, a computer). However, if the portable terminal device 4 is a portable small portable terminal device 4, a surveying operator together with the three-dimensional surveying instrument 5 Since the apparatus 4 can be easily transported to the site, the measurement of the building accuracy proceeds smoothly, which is preferable.

  The three-dimensional surveying instrument 5 is a surveying instrument generally used at a construction site. When a predetermined measurement instruction is received, the three-dimensional surveying instrument 5 is a target installed on the outer surface of a building member (column or beam) of the building at the construction site. The position of the seal is measured as measured seal position information in a survey coordinate system (orthogonal coordinate system), and the measured measured seal position information is input to the mobile terminal device 4.

  Here, when the three-dimensional surveying instrument 5 measures the actual seal position information of the target seal, the surveying operator inputs a predetermined operation, whereby the initial position of the three-dimensional surveying instrument 5 (horizontal angle, vertical When the relative angle from the angle of zero is received, the three-dimensional surveying instrument 5 itself changes the direction to the relative angle and automatically collimates (finds the target seal). This reduces the burden on surveying operators. In addition, the structure which makes the collimation axis | shaft of the said three-dimensional surveying instrument 5 made | formed generally in the direction of a target seal | sticker (collimation) may be sufficient.

  The survey information extraction device 2, the server computer 3, the portable terminal device 4, and the three-dimensional survey instrument 5 incorporate a CPU, ROM, RAM, and HDD (not shown). A program stored in a ROM, HDD or the like is used as a work area. Also, each means (shown in FIG. 2) described later is realized by the CPU executing a program.

  <Example according to the present invention>

  Next, the configuration and execution procedure according to the present invention will be described with reference to FIGS. FIG. 2 is a functional block diagram of the building quality control system 1 including the survey information extraction device 2 according to the present invention. FIG. 3 is a flowchart for showing an execution procedure for extracting and calculating surveying information according to the present invention, and FIG. 4 is a flowchart for showing an execution procedure for a program according to the present invention. Furthermore, FIG. 5 is a flowchart for showing the execution procedure of the measurement of the building accuracy according to the present invention.

  First, when a surveyor receives an object-oriented CAD (object CAD) in a predetermined building from a structural designer or the like by a predetermined recording medium (for example, CD-ROM, USB memory, etc.) or e-mail, The object CAD is stored in the survey information extraction device 2.

  That is, a surveying operator inputs a storage instruction to the surveying information extracting device 2 via a predetermined operation unit, and the surveying information extracting device 2 stores the object CAD (data) in a predetermined memory (for example, an object CAD). The data is stored in the storage unit 201) (FIG. 3: S101).

  Here, in the object CAD (data structure) 600, as shown in FIG. 6, member information 601 related to the building in the object CAD and a predetermined number of attribute information indicating attributes (features) of the member information 601 602 is stored in association with each other.

  In this way, CAD in a format that expresses a predetermined building by associating predetermined attribute information 602 for each member information 601 is referred to as object-oriented CAD. In the object CAD 600, each member information 601 can be identified (recognized).

  The member information 601 includes street information 601a for identifying a street of a building, column information 601b for identifying a column, beam information 601c for identifying a beam, wall information 601d for identifying a wall, and a bolt. Possible bolt information 601e corresponds to this. The member information to be measured for the building accuracy is mainly the column information 601b and the beam information 601c, and both are hereinafter referred to as building member information. Note that the number of the member information 601 may range from several hundred to several thousand depending on the type of the object CAD 600.

  The attribute information 602 differs in number and type depending on the type of the member information 601. For example, in the case of the street information 601a, the attribute information 602 includes position information (position information of each column core in the X-axis direction) in the coordinate system of the object CAD, and street information in the Y-axis direction. This corresponds to position information (position information of the core of each pillar in the Y-axis direction), level position information of each floor of the building (position information of each floor in the Z-axis direction), and the like. Here, the coordinate system of the object CAD means a coordinate system expressed using the origin of the object CAD as a reference. The same applies hereinafter.

  For example, in the case of the column information 601b, the attribute information 602 includes a steel frame standard information 602a (for example, a character string) indicating a standard of a steel frame constituting the column of the column information 601b, and a column of the column information 601b. The position information 602b of the object CAD in the coordinate system, the rotation position information 602c of the column of the column information 601b in the coordinate system of the object CAD, and the rotation angle 602d of the column of the column information 601b in the coordinate system of the object CAD And an offset 602e indicating a conversion value for converting the coordinate system of the object CAD of the column information 601b into a survey coordinate system.

  The position information 602b is a start point coordinate value and an end point coordinate value in the coordinate system of the object CAD indicated by a three-dimensional coordinate value, and the start point coordinate value indicates a lower end portion of a corresponding building member, The end point coordinate value indicates the upper end portion of the corresponding building member. The rotational position information 602c is information indicating the orientation of the (building) member information 601 with respect to the normal position (set position) of the (building) member. Then, “down”, “front” in the front direction, and “back” in the back direction are applicable. The offset 602e usually has conversion values corresponding to the X-axis direction and the Y-axis direction, and is an offset in the X-axis direction and an offset in the Y-axis direction (described later).

  The attribute information 602 in the case of the beam information 601c is the same as the column information 601b, and the steel frame standard information 602a, the position information 602b, the rotation position information 602c, the rotation angle 602d, and the offset 602e are included. Applicable.

  Note that the attribute information of the member information 601 other than the building member information is not directly related to the embodiment of the present invention, and thus the description thereof is omitted.

  As described above, the number of data of the object CAD 600 may usually be enormous. For example, if all of the member information 601 and the attribute information 602 are included, the data may be several thousand to several tens of thousands. is there.

  When the object CAD is stored in the object CAD storage unit 201, the surveying operator inputs an instruction to extract predetermined survey information from the object CAD to the survey information extracting device 2 using the operation unit. To do. Then, the extraction means 202 of the survey information extraction apparatus 2 receives the input of the extraction instruction (FIG. 3: S102 YES), and according to a predetermined program (conversion program) stored in advance, of the member information of the object CAD The column information 601b of the columns constituting the building or the beam information 601c (building member information) of the beam is searched, and the attribute information 602 of the searched building member information is extracted (FIG. 3: S103).

  Further, the calculation means 203 of the survey information extraction apparatus 2 measures the building accuracy of the column of the column information 601b or the beam of the beam information 601c based on the extracted attribute information 602 according to the program. Necessary survey information is calculated (FIG. 3: S104).

  <Acquisition of street location information and level location information of each floor>

  Here, the content of the program is specifically as shown in FIG. 4 and proceeds according to the following processing. First, the extracting unit 202 searches the street information 601a in the member information 601 of the object CAD 600 of the object CAD storage unit 201, and refers to the attribute information 602 corresponding to the searched street information 601a. As described above, the referenced attribute information 602 stores position information as in the X-axis direction, position information as in the Y-axis direction, and level position information of each floor of the building. These pieces of information are acquired (FIG. 4: S201).

  Here, since the position information in the X-axis direction, the position information in the Y-axis direction, and the level position information of each floor of the building in the street information are directly used as the survey information, the calculation unit 203 is not particularly activated. .

  <Calculation (acquisition) of vertical and horizontal dimensions of building components>

  Next, the extraction unit 202 searches the member information 601 of the object CAD 600 for building member information (column information 601b and beam information 601c) to be measured for building accuracy, and corresponds to the searched building member information. The attribute information 602 to be referred to is referred to. And the said extraction means 202 acquires the position shape attribute information 602 which shows the position and shape in the building member of the said building member information among the referred attribute information 602, for example, the steel frame standard information 602a, The fact is said to the said The calculation means 203 is notified. Upon receiving the notification, the calculation means 203 calculates the dimension (vertical dimension) in the X-axis direction and the dimension (lateral dimension) in the Y-axis direction of the building member in the building member information based on the steel frame standard information 602a ( FIG. 4: S202).

  Any method may be used for calculating the vertical dimension and the horizontal dimension. For example, normally, the vertical dimension and the horizontal dimension of the corresponding steel frame are uniquely determined for the steel standard information 602a. . Therefore, first, a steel size table that associates the steel frame standard information 602a (for example, a character string) with the vertical dimension (mm) and the horizontal dimension (mm) of the corresponding steel frame is stored in a predetermined memory in advance. Or incorporated into the program. Next, the calculation means 203 collates the steel frame standard information of the steel frame dimension table with the acquired steel frame standard information 602a, and acquires the vertical dimension and the horizontal dimension corresponding to the collated steel frame standard information. . Thereby, the vertical dimension and the horizontal dimension of the building member of the building member information are calculated.

  <Calculation of building member length>

  Next, the extraction unit 202 acquires position information 602b included in the position shape attribute information among the attribute information 602 corresponding to the building member information, and the calculation unit 203 is based on the position information 602b. The member length of the building member is calculated according to the type of building member in the building member information (FIG. 4: S203).

  Here, the member length corresponds to the length of the building member in the axial direction (longitudinal direction), and the calculation method differs depending on the type of column or beam.

For example, when the calculation unit 203 calculates the member length of the column information 601b in the building member information, the position information 602b corresponding to the column information 601b mainly corresponds to the height of the column. By substituting the start point coordinate value Zs (mm) and the end point coordinate value Ze (mm) of the direction into the following formula (1), the member length Lp (mm) of the pillar of the column information 601b is calculated. To do.
Lp = Ze-Zs (1)

On the other hand, when the calculation unit 203 calculates the member length of the beam information 601c among the building member information, all of the position information 602b corresponding to the beam information 601c, that is, the X axis, the Y axis, and the Z axis. Start point coordinate values Xs (mm), Ys (mm), Zs (mm) in the direction, and end point coordinate values Xe (mm), Ye (mm), Ze (mm) in the X-axis, Y-axis, and Z-axis directions By substituting into the following equation (2), the member length Lc (mm) of the beam of the beam information 601c is calculated.
Lc = {(Xe−Xs) ² + (Ye−Ys) ² + (Ze−Zs) ² } ^1/2 (2)

  <Calculation of survey core position information of building members>

  Now, the position information 602b of the building member in the object CAD is based on the difference between the coordinate system of the object CAD and the survey coordinate system that defines the measured position information measured by the three-dimensional surveying instrument 5. It cannot be used as it is for surveying core position information indicating the position of the member core (core, center) of the building member. Therefore, it is necessary to calculate (convert) the building member position information 602b in the object CAD into the survey core position information in the survey coordinate system according to the following procedure.

  Here, the calculation method differs depending on the type of position information 602b in the coordinate system of the object CAD (how to obtain the position information, etc.). When the position information 602b of the building member in the object CAD adopts the coordinate value of the core of the corresponding building member, the corresponding offset 602e is added to the position information 602b, so that the column in the survey coordinate system It is possible to calculate the survey core position information. When calculating the survey core position information, since the start point coordinate value and the end point coordinate value exist in the position information 602b, any appropriate coordinate value is adopted depending on the type. Then, the survey core position information is calculated.

Specifically, the extraction unit 202 includes, in the attribute information 602 corresponding to the building member information, the start point coordinate values in the X-axis and Y-axis directions in the position information 602b, and the offset 602e (X-axis, Y-axis). Direction offset). Here, since the start point coordinate value in the X-axis and Y-axis directions corresponds to the lower end portion of the building member as described above, it becomes a reference (basic) coordinate value for calculating the building accuracy. Next, the calculation unit 203 calculates the acquired start point coordinate values Xs (mm) and Ys (mm) in the X-axis and Y-axis directions and offsets Ox (mm) and Oy (mm) in the X-axis and Y-axis directions. By substituting into the following formulas (3-1) and (3-2), the survey core position information Sx (mm) and Sy (mm) of the building member is calculated (FIG. 4: S204).
Sx = Xs + Ox (3-1)
Sy = Ys + Ox (3-2)

  In addition, the coordinate system of the object CAD and the survey coordinate system are usually the same in the Z-axis direction, except that the origin on the XY plane is different. In this case, the end point coordinate value Ze (mm) in the Z-axis direction is adopted as the reference coordinate value for calculating the building accuracy among the position information 602b in the object CAD, and this is the survey in the survey coordinate system. It is used as it is for the core position information.

  By the way, when the position information 602b of the building member information in the object CAD does not adopt the coordinate value of the core of the corresponding building member, the surveying core position information in the surveying coordinate system according to the contents of each object CAD. The calculation method is appropriately changed and incorporated in the program.

  For example, when the building member information position information 602b in the object CAD adopts the intersection of the corresponding building member and another building member adjacent thereto, the extraction means 202 is similar to the above. The X-axis and Y-axis direction start point coordinate values and the offset 602e (X-axis and Y-axis direction offset) in the position information 602b are acquired. Here, the calculation means 203 calculates the start point coordinate value in the X-axis and Y-axis directions, the offset in the X-axis and Y-axis directions, and the horizontal and vertical dimensions of the building member from the intersection. The distance to the back is calculated backward to calculate the survey core position information of the building member.

  In addition, the attribute information 602 of the object CAD includes the position of the building member in the X-axis and Y-axis directions, that is, the X-axis direction (left and right) (left, middle, and right) and the Y-axis direction ( When there is an up / down shift (upper, middle, lower), the calculation means 203 considers the information of these shifts and calculates the survey core position information of the building member. Become. As described above, this area can be appropriately changed according to the contents of the object CAD.

  <Calculation of surveying rotation angle of building materials>

  Further, the rotation position information 602c and the rotation angle 602d in the object CAD cannot be used as they are for the survey rotation angle in the survey coordinate system due to the difference between the coordinate system of the object CAD and the survey coordinate system. Of the building members, the pillar has a predetermined axis on the XY plane in which its own axial direction is mainly along the Z-axis direction, and the beam has its own axial direction mainly composed of the X-axis and the Y-axis. In order to follow the direction, the surveying rotation angle will differ depending on the type of column or beam. Therefore, it is necessary to calculate (convert) the rotation position information 602c and the rotation angle 602d in the object CAD into the survey rotation angle in the survey coordinate system according to the type of the building member information according to the following procedure.

  Specifically, the extraction unit 202 determines the rotation position information 602c and the rotation angle 602d or position information 602b included in the position shape attribute information among the corresponding attribute information 602 according to the type of the building member information. The calculation means 203 corresponds to the type of the building member information, and based on the rotation position information 602c and the rotation angle 602d or the position information 602b, The surveying rotation angle is calculated (FIG. 4: S205).

For example, when the calculation unit 203 calculates the surveying rotation angle of the column information 601b in the building member information, the type (“up”, “down”, “correct” of the rotation position information 602c of the column information 601b is calculated. ”,“ Back ”) by substituting the rotation angle Ro (rad) 602d corresponding to the column information 601b into the following four types of expressions (4-1)-(4-4). Survey rotation angles Rx (rad), Ry (rad), and Rz (rad) for each axis of the information 601b are calculated. Note that PI represents a circumference ratio.
When the rotational position information 602c of the column information 601b is “up” Rx = 0, Ry = 0, Rz = PI / 2 + Ro (4-1)
When the rotation position information 602c of the column information 601b is “down” Rx = 0, Ry = 0, Rz = (3/2) × PI + Ro (4-2)
When the rotational position information 602c of the column information 601b is “positive” Rx = 0, Ry = 0, Rz = Ro (4-3)
When the rotation position information 602c of the column information 601b is “back” Rx = 0, Ry = 0, Rz = PI + Ro (4-4)

On the other hand, when the calculation unit 203 calculates the surveying rotation angle of the beam information 601c among the building member information, first, the type of the rotation position information 602c of the beam information 601c ("up", "down", According to the following four types of equations (4-5) to (4-8) corresponding to “positive” and “back”), the first survey rotation angle Rx0 (rad), Ry0 for each axis of the beam information 601c (Rad) and Rz0 (rad) are determined. In this case, the rotation angle 602d is not used.
When the rotational position information 602c of the beam information 601c is “up” Rx0 = PI / 2, Ry0 = 0, Rz0 = 0 (4-5)
When the rotational position information 602c of the beam information 601c is “down” Rx0 = −PI / 2, Ry0 = 0, Rz0 = 0 (4-6)
When the rotational position information 602c of the beam information 601c is “positive” Rx0 = PI / 2, Ry0 = 0, Rz0 = PI / 2 (4-7)
When the rotational position information 602c of the beam information 601c is “back” Rx0 = PI / 2, Ry0 = 0, Rz0 = −PI / 2 (4-8)

Next, when the beam of the beam information 601c is inclined on at least one of the YZ plane, the ZX plane, and the XY plane, the calculation unit 203 calculates the beam information 601c. Position information 602b (ie, the start point coordinate values Xs (mm), Ys (mm), Zs (mm) in the X-axis, Y-axis, and Z-axis directions) and end-point coordinates in the X-axis, Y-axis, and Z-axis directions By substituting the values Xe (mm), Ye (mm), and Ze (mm) into the following four types of equations (4-9) to (4-11), the first calculation for each axis calculated above is performed. Correction values ΔRx0 (rad), ΔRy0 (rad), and ΔRz0 (rad) of the surveying rotation angles Rx0 (rad), Ry0 (rad), and Rz0 (rad) are calculated.
ΔRx0 = tan ⁻¹ {(Ye−Ys) / (Ze−Zs)} * (180 / PI) (4-9)
ΔRy0 = tan ⁻¹ {(Xe−Xs) / (Ze−Zs)} * (180 / PI) (4-10)
ΔRz0 = tan ⁻¹ {(Ye−Ys) / (Xe−Xs)} * (180 / PI) (4-11)

Then, the calculation means 203 substitutes the calculated correction values ΔRx0 (rad), ΔRy0 (rad), and ΔRz0 (rad) into the following three types of equations (4-12)-(4-14). , By adding to the first surveying rotation angles Rx0 (rad), Ry0 (rad), Rz0 (rad) for each axis, the surveying rotation angles Rx (rad), Ry (for each axis of the beam information 601c). rad) and Rz (rad) are calculated.
Rx = Rx0 + ΔRx0 (4-12)
Ry = Ry0 + ΔRy0 (4-13)
Rz = Rz0 + ΔRz0 (4-14)

  <Calculation of cross-sectional shape information of building members>

  The extracting unit 202 acquires the steel frame standard information 602a included in the position shape attribute information from the attribute information 602 corresponding to the building member information, and the calculating unit 203 is based on the steel frame standard information 602a. Then, the cross-sectional shape of the building member of the building member information 602a is calculated (FIG. 4: S206).

  Any method may be used to calculate the cross-sectional shape of the building member. For example, the cross-sectional shape perpendicular to the longitudinal direction of the corresponding steel frame is typically uniquely determined in advance with respect to the steel standard information 602a. Is done. Therefore, as with the steel frame dimension table, first, the steel frame standard information and the corresponding cross-sectional shape information of the steel frame (for example, “H” for H steel, “O” for a cylinder, square column) For example, a steel cross-sectional shape table associated with “□”) is stored in advance in a predetermined memory or incorporated in the program. Next, the calculation unit 203 collates the steel standard information of the steel cross-sectional shape table with the acquired steel standard information 602a, and acquires cross-sectional shape information corresponding to the collated steel standard information. Then, the cross-sectional shape of the building member in the building member information is calculated.

  <Calculation of building material placement floor (section)>

  In addition, the building member information in the object CAD does not include information on the arrangement floor (section) on which the building member of the building member information is arranged in the building. For this reason, according to the following procedure, the level position information of the street information 601a in the object CAD and the position information 602b of the building member information (starting point coordinate value in the Z-axis direction) are used. Clause) must be calculated.

  Specifically, first, the extraction unit 202 acquires the level position information of the information 601a and the start point coordinate value Zs (mm) in the Z-axis direction of the building member information that is the calculation target of the arrangement floor.

  Here, the level position information of the information 601a is composed of coordinate values in the Z-axis direction for each floor. For example, in the case of a two-story building, the level position information Zf (mm) is 1 The coordinate value Zf1 (mm) in the Z-axis direction of the floor is the coordinate value Zf2 (mm) in the Z-axis direction of the second floor.

  Therefore, the calculation means 203 compares (determines) the starting point coordinate value Zs (mm) in the Z-axis direction of the building member information and the level position information Zf (mm) in the order of the floor. In the above-described case, first, the Z-axis direction coordinate value Zf1 (mm) of the first floor is compared with the Z-axis direction start point coordinate value Zs (mm) of the building member information.

  As a result of the comparison, when the starting point coordinate value Zs (mm) is larger than the level position information Zf1 (mm), the calculation means 203 calculates the next floor of the level position information Zf1 (mm). The level position information Zf2 (mm) corresponding to is compared with the start point coordinate value Zs (mm).

  On the other hand, as a result of the comparison, when the starting point coordinate value Zs (mm) is smaller than the level position information Zf (mm), the calculation means 203 calculates the level (level) of the level position information Zf (mm). ) Is calculated (determined) as an arrangement floor (node) of the building member information (FIG. 4: S207).

  For example, when the starting point coordinate value Zs (mm) is smaller than the coordinate value (level position information) Zf2 (mm) in the Z-axis direction of the second floor, the arrangement floor (node) of the building member information is 2 It becomes.

  By executing such a comparison / calculation process for each building member information, the calculating means 203 calculates a predetermined arrangement floor (section) for each building member information.

  <Evacuation of location information of building member information>

  The position information 602b of the building member information in the object CAD may be updated after calculating the building accuracy described later. Therefore, the extraction unit 202 or the calculation unit 203 temporarily stores the position information 602b of the building member information in another memory, and the position information 602b of the building member information in the object CAD of the object CAD storage unit 201. The data is saved (erased) (FIG. 4: S208).

  <Calculation of surveying seal position information of target seals placed on building members>

  Finally, the calculation means 203 is based on the cross-sectional shape information corresponding to the building member information calculated above, the horizontal and vertical dimensions, the survey rotation angle, the survey core position information, and geometric relational expressions. According to the type of cross-sectional shape of the building member in the building member information, the surveying seal position information of the target seal installed on the outer surface of the building member is calculated (FIG. 4: S209).

First, when the cross-sectional shape information corresponding to the building member information is “H”, the surveying operator measures the right and left 2 of the “H” when measuring the building accuracy of the building member of the building member information. Install target seals on the outer surfaces of the two flanges. Therefore, when the cross-sectional shape is H shape, the calculation means 203 corresponds to the outer surface of the flange in the H steel of the building member, and the horizontal and vertical dimensions Wx (mm) corresponding to the building member information. , Wy (mm), the surveying rotation angle Rz (rad) in the Z-axis direction at the surveying rotation angle is substituted into the following four types of equations (5-1) to (5-4), and FIG. 2, two types of distances Dx (mm) and Dy (mm) on the left and right from the core of the building member in the building member information to the outer surface on which the target seals (P1, P2) are installed are calculated.
Distance to the flange outer surface on the right side of the “H” Dx1 = (Wy / 2) * cos (Rz) -0 * sin (Rz) (5-1)
Dy1 = (Wy / 2) * sin (Rz) + 0 * cos (Rz) (5-2)
Distance to the left flange outer surface of “H” Dx2 = (− Wy / 2) * cos (Rz) −0 * sin (Rz) (5-3)
Dy2 = (− Wy / 2) * sin (Rz) + 0 * cos (Rz) (5-4)

Then, the calculating means 203 calculates the calculated distances Dx1 (mm), Dy1 (mm), Dx2 (mm), Dy2 (mm) and the survey core position information Sx (mm), Sy (mm), Ze ( mm) is substituted into the following six types of equations (5-5)-(5-10), so that the survey seal position information Tx (mm) of the target seal installed on the outer surface of the building member, Two types of Ty (mm) and Tz (mm) are calculated.
Survey seal position information (P1) of the first target seal installed on the flange outer surface on the right side of “H”
Tx1 = Sx + Dx1 (5-5)
Ty1 = Sy + Dy1 (5-6)
Tz1 = Ze−ΔTz (5-7)
Surveying seal position information (P2) of the second target seal installed on the outer surface of the left flange of “H”
Tx2 = Sx + Dx2 (5-8)
Ty2 = Sy + Dy2 (5-9)
Tz2 = Ze−ΔTz (5-10)

  Here, the ΔTz (mm) corresponds to the distance from the end point (top end) of the building member in the preset Z-axis direction, and the surveyor before the building accuracy is measured, It is a value that is determined and input in advance. The ΔTz (mm) is reflected in the height of the installation position of the target seal installed on the outer surface of the building member at the site. Therefore, when the surveying operator has determined the height of the target seal installation position in advance, the ΔTz (mm) may be set in advance, or the design may be changed appropriately according to the situation at the site. Then, when inputting the extraction instruction, it may be input on the screen, or the survey operator may input the ΔTz (mm) again.

On the other hand, when the cross-sectional shape information corresponding to the building member information is “◯” or “□”, the surveying operator, when measuring the building accuracy of the building member of the building member information, ”Or“ □ ”, target seals are installed on the four outer surfaces of the top, bottom, left, and right respectively. Therefore, when the cross-sectional shape is a circular shape or a quadrangular shape, the calculation unit 203 corresponds to the outer surface of each side of the column or quadrangular column of the building member, and the horizontal / vertical length corresponding to the building member information. Substituting the dimensions Wx (mm), Wy (mm), and the survey rotation angle Rz (rad) in the Z-axis direction at the survey rotation angle into the following eight types of equations (6-1) to (6-8) Then, as shown in FIG. 7 (B), the distances Dx (mm), Dy (mm) from the core of the building member of the building member information to the outer surface on which the target seal (P1-P4) is installed. ) 4 points. FIG. 7B shows the case where the cross-sectional shape is “□”.
Distance to right outer surface of “◯” or “□” Dx1 = (Wy / 2) * cos (Rz) -0 * sin (Rz) (6-1)
Dy1 = (Wy / 2) * sin (Rz) + 0 * cos (Rz) (6-2)
Distance to the left outer surface of the “◯” or “□” Dx2 = (− Wy / 2) * cos (Rz) −0 * sin (Rz) (6-3)
Dy2 = (− Wy / 2) * sin (Rz) + 0 * cos (Rz) (6-4)
Distance to the upper outer surface of “◯” or “□” Dx3 = 0 * cos (Rz) − (− Wx / 2) * sin (Rz) (6-5)
Dy3 = 0 * sin (Rz) + (− Wx / 2) * cos (Rz) (6-6)
Distance to lower outer surface of “◯” or “□” Dx4 = 0 * cos (Rz) − (Wx / 2) * sin (Rz) (6-7)
Dy4 = 0 * sin (Rz) + (Wx / 2) * cos (Rz) (6-8)

In the same manner as described above, the calculating unit 203 calculates the calculated distances Dx1 (mm), Dy1 (mm), Dx2 (mm), Dy2 (mm), Dx3 (mm), Dy3 (mm), Dx4 (mm). ), Dy4 (mm), the surveying center position information Sx (mm), Sy (mm), and the end point coordinate value Ze (mm) in the Z-axis direction are expressed by the following 12 types of equations (6-9)-( By substituting into 6-20), four types of surveying seal position information Tx (mm), Ty (mm), and Tz (mm) of the target seal installed on the outer surface of the building member are calculated. The ΔTz (mm) has the same meaning as described above.
Survey seal position information (P1) of the first target seal installed on the outer surface on the right side of the “◯” or “□”
Tx1 = Sx + Dx1 (6-9)
Ty1 = Sy + Dy1 (6-10)
Tz1 = Ze−ΔTz (6-11)
Survey seal position information (P2) of the second target seal installed on the outer surface on the right side of the “◯” or “□”
Tx2 = Sx + Dx2 (6-12)
Ty2 = Sy + Dy2 (6-13)
Tz2 = Ze−ΔTz (6-14)
Surveying seal position information (P3) of the third target seal installed on the outer surface above “◯” or “□”
Tx3 = Sx + Dx3 (6-15)
Ty3 = Sy + Dy3 (6-16)
Tz3 = Ze−ΔTz (6-17)
Survey seal position information (P4) of the fourth target seal installed on the lower outer surface of the “◯” or “□”
Tx4 = Sx + Dx4 (6-18)
Ty4 = Sy + Dy4 (6-19)
Tz4 = Ze−ΔTz (6-20)

  The calculation means 203 may calculate the target seal even if the cross-sectional shape information corresponding to the building member information is “H”, or “◯” or “□”. The coordinate system of the surveying seal position information (P1-P4) is the surveying coordinate system. Thereby, all the extraction / calculation processes are completed.

  As described above, the extraction means 202 and the calculation means 203 require survey information (vertical dimensions / horizontal dimensions, member length, survey core position information, survey rotation angle, cross section) required for measuring the building accuracy of the building member. The shape information, nodes, and surveying seal position information of the target seal) are all automatically extracted and calculated based on the object CAD. As a result, the surveying operator can omit the conventional work of checking the building member of the object CAD and the work of calculating the survey information by manual work.

  Further, as described above, since the number of data of the object CAD 600 usually reaches an enormous amount (several thousands to several tens of thousands), the confirmation work and calculation work of the survey information for these data are troublesome. It may take several days (such as 1 to 2 days). In the present invention, although the time required for the extraction / calculation process described above depends on the data amount of the object CAD, it is about several minutes (1 minute-2 minutes, etc.). It is understood that it has been dramatically shortened.

  In S104, when the calculation unit 203 calculates all the survey information, the calculation unit 203 notifies the storage unit 204 to that effect. The storage unit 204 that has received the notification accesses the server computer 3 via the network 6 and stores the information 601a and the corresponding attribute information 602 (in the X-axis direction) in the survey information storage unit 205 of the server computer 3 as described above. Street position information, street position information in the Y-axis direction, level position information of each floor of the building), and the building member information (column information 601b and beam information 601c) and the survey information calculated in S202-S209 ( The vertical dimension / horizontal dimension, member length, surveying core position information, surveying rotation angle, cross-sectional shape information, nodes, surveying seal position information of the target seal) are associated and stored (stored) as a surveying information table (FIG. 3: S105).

  As shown in FIG. 8, the survey information table 800 stores the street information 801, the street location information and the level location information 802 in association with the X-axis and Y-axis directions, and the building member. Information 803 (column information 601b and beam information 601c) and the corresponding surveying information 804 are stored in association with each other. In addition, as shown in FIG. 8, the surveying information table 800 is provided with a column for inputting the building accuracy 805 corresponding to the building member information 803.

  This eliminates the need for the surveying operator to manually input and save the calculated surveying information 804 in a predetermined recording paper or computer database, for example, further reducing the burden on the surveying operator. .

  Now, when the storage of the survey information 804 is completed, all the processes of the survey information extraction apparatus 2 corresponding to the extraction instruction are completed.

  <Measurement of the accuracy of building materials>

  By the way, the calculation of the building accuracy of the building member proceeds according to the following process, as shown in FIG. For example, when the survey information 804 is stored in the survey information extraction device 2, the survey operator has the portable terminal device 4 and the three-dimensional survey instrument 5 in a building (construction site) in the object CAD. The target seal is installed on the outer surface of the building member (column or beam) of the building (FIG. 5: S301).

  Here, as shown in FIG. 7 (A) or FIG. 7 (B), the position of the outer surface on which the target seal is installed is survey seal position information (P1, P2 or P1-P4) of the target seal. In accordance with the type of the cross-sectional shape of the building member, the surveying operator can place the target seal at one or more specific locations out of 2 locations (P1, P2) and 4 locations (P1-P4). Will be installed in. Further, the surveying operator installs the target seal at a predetermined position in consideration of the distance ΔTz (mm).

  Then, when the surveying operator activates the portable terminal device 4 and inputs the building member information of the building member to be measured among the building members where the target seal is installed, the portable terminal device 4 The surveying means 206 of the terminal device 4 accepts the input of the building member information (FIG. 5: S302 YES), accesses the server computer 3 via the network 6, and survey information in the survey information storage means 205 of the server computer 3 Refer to table 800.

  As shown in FIG. 8, the surveying information table 800 stores the building member information 803 stored earlier and the surveying information 804 corresponding to the building member information 803 in association with each other. Compares the building member information 803 of the survey information table 800 with the input building member information 803, and acquires the survey seal position information of the target seal of the survey information 804 corresponding to the collated building member information 803 (FIG. 5: S303).

  Then, the surveying means 206 causes the display unit of the portable terminal device 4 to display the acquired survey seal position information of the target seal. Thereby, the surveying operator can confirm the surveying seal position information of the target seal of the building member whose building accuracy is to be measured from now.

  Further, the surveying operator activates the three-dimensional surveying instrument 5, collimates the reference point, and inputs a predetermined measurement instruction to the portable terminal device 4 (FIG. 5: S304 YES), the surveying means 206 In response to the input of the measurement instruction, the three-dimensional surveying instrument 5 is made to measure the measured seal position information of the target seal. The three-dimensional surveying instrument 5 measures the measured seal position information (three-dimensional coordinate value) of the target seal by aligning its collimation axis with the direction of the target seal (FIG. 5: S305).

  When the three-dimensional surveying instrument 5 measures the measured seal position information of the target seal, the three-dimensional surveying instrument 5 notifies the surveying means 206 to that effect, and the surveying means 206 that has received the notification has acquired the measured seal position information and the previous information. Based on the survey seal position information of the target seal, the building accuracy of the building member where the target seal is installed is calculated (FIG. 5: S306).

  Here, the building accuracy is calculated by subtracting the design coordinate value for each axis from the measured coordinate value of the core of the building member where the target seal is installed (for example, the core of the column if it is a column). As the types of the building accuracy, the fall value in the X-axis direction (mm), the fall value in the Y-axis direction (mm), and the level accuracy (mm) are applicable. Here, the construction accuracy is obtained by subtracting the corresponding surveying seal position information (three-dimensional coordinate value) for each axis from the measured seal position information (three-dimensional coordinate value) of the target seal at a specific installation location. Is calculated. When target seals are installed at multiple locations, for example, the average value of the building accuracy calculated for each target seal is calculated, or calculated from the measured seal position information of the last installed target seal. In some cases, the built accuracy is adopted.

  When the surveying means 206 completes the calculation of the building accuracy of the building member, the building accuracy is displayed on the display unit of the mobile terminal device 4. As a result, the surveying operator can examine whether or not the calculated building accuracy is appropriate. If the accuracy of the building is not appropriate, the surveying operator checks the installation position of the target seal and measures again.

  On the other hand, when the surveying operator determines that the building accuracy is appropriate, if the surveying operator 206 inputs a predetermined transmission instruction to the portable terminal device 4, the surveying means 206 accepts the input of the transmission instruction (FIG. 5). : S307 YES), the server computer 3 is accessed again via the network 6, and the survey information table 800 of the survey information storage means 205 of the server computer 3 is referred to. Then, as shown in FIG. 8, the surveying means 206 stores the building accuracy (X-axis direction) calculated in the building accuracy column 805 corresponding to the input building member information 803 in the surveying information table 800. The tilt value, the tilt value in the Y-axis direction, and the level accuracy) are stored in association with each other (FIG. 5: S308).

  This eliminates the need for the surveying operator to manually calculate or fill in the calculated building accuracy on the recording paper, etc. And the like can be reliably prevented.

  When the construction accuracy is stored in the survey information table 800, the server computer 3 notifies the survey information extraction device 2 to that effect, and the survey information extraction device 2 that has received the notification stores the object CAD storage. In the object CAD 600 of the means 201, the position information 602b of the building member information evacuated as described above is re-stored (updated) with appropriate position information corresponding to the building accuracy (or measured seal position information) You may comprise so that it may memorize | store as new positional information for every measurement stage (construction stage). In this case, it goes without saying that the stored position information is after being converted from the surveying coordinate system to the coordinate system of the object CAD.

  As described above, the above-described operation is repeated for each building member of the building on site, thereby measuring the building accuracy of the building.

  Now, after the measurement of the building accuracy is completed, the surveyor returns to the company, for example, uses the survey information extraction device 2 (or other terminal device), and uses the server computer via the network 6. 3, the reference means 207 of the survey information extraction device 2 (or another terminal device) refers to the survey information table 800 of the survey information storage means 205 of the server computer 3. The reference means 207 stores information 801 stored in the survey information table 800, position information along the X-axis and Y-axis directions, level position information 802, building member information 803, survey information 804, and building accuracy 805. Is acquired, and based on the acquired information, the plan view of the building at a predetermined node and the building accuracy for each building member (column or beam) on the plan view are displayed.

  As a result, the surveying operator can easily confirm the building accuracy of the building even if the building to be measured for the building accuracy is represented by the object CAD.
