Description

  The present invention relates to a work form management apparatus for managing whether or not a construction result satisfies a dimension determined by design.

  In civil engineering work such as embankment construction and slope formation, workmanship management is performed to determine whether the construction is performed according to the construction drawings. In order to improve the efficiency of the finished shape management, a system using a total station having an electronic distance measuring device is used (Non-Patent Document 1). In addition, as the total station, an electronic theodolite is built in, and thereby a three-dimensional coordinate is obtained, or an electronic theodolite is not incorporated, and a three-dimensional coordinate is obtained based on a reference point.

  According to this system, design data (referred to as TS input data) is read and created on the basis of a construction sectional view to be managed. Next, the completed shape is measured for the cross section to be managed by the total station. By comparing the measured shape measurement data measured in this way with the TS input data, the completed shape can be managed.

  However, in the conventional system as described above, first, TS input data has to be read and created from a construction sectional view, which takes time.

  Secondly, since only the cross section prepared as the construction drawing is a management target, it was not possible to perform management at detailed intervals. In addition, when adding a new management target, it had to be prepared from the construction cross-sectional view. For this reason, there existed a problem that it was not suitable for the total number management which manages in arbitrary cross sections.

  Thirdly, TS input data and ready-made measurement data have a data structure different from generally used three-dimensional CAD data. Therefore, in the future, when 3D CAD data is added to the delivery target data in the electronic delivery guidelines established by the Ministry of Land, Infrastructure, Transport and Tourism, it will be necessary to create 3D CAD data and TS input data. There was a problem that it took.

  Therefore, three-dimensional CAD ready-made data can be generated based on the ready-made measurement data and compared with the three-dimensional CAD design data.

(5) In the completed shape management device according to the present invention, the component point determining means has a straight line connecting the plurality of intersections, and an angle formed by two straight lines adjacent to each other across the intersections is within a predetermined range of about 180 degrees. In this case, the process of deleting the intersection is repeated, and the remaining intersection is determined as a constituent point.

  Therefore, an important intersection indicating the shape of the object can be extracted as a constituent point.

1. Overview of System FIG. 1 shows a conceptual diagram of a product form management according to an embodiment of the present invention. Based on the construction drawing, three-dimensional CAD design data is generated. Construction management data (TS input data) is generated based on the three-dimensional CAD design data. The construction management data includes the center line and the constituent points of the object.

  When civil engineering work (filling work, slope formation, etc.) is completed, the finished shape is measured using the total station (TS). The measured measurement data of each component point measured is linked to the component point of the construction management data and recorded. Next, based on the measurement data, three-dimensional CAD result data is generated.

  By comparing the three-dimensional CAD design data generated as described above and the three-dimensional CAD ready-made data, it is determined whether or not the construction has been performed as designed. Specifically, a completed form management form is generated.

  In FIG. 1, the functional block diagram of the construction management system by one Embodiment of this invention is shown. The 3D CAD design data receiving means 2 receives 3D CAD design data from a 3D CAD program or the like. The center line acquisition means 4 extracts the center line of an object (for example, a road) described in the three-dimensional CAD design data. The constituent point determination means 6 sets a plurality of predetermined cross sections (cross sections for performing the measurement of the finished shape) that intersect (for example, orthogonal to) the center line. In each set cross section, the intersection of the polygon outline constituting the three-dimensional CAD design data and the cross section is extracted. The composition point determination means 6 determines a composition point based on each intersection extracted on the cross section.

  The construction management data generation means 8 generates construction management data based on the center line and the constituent points obtained as described above. Further, the first identification code assigning means 10 is configured to clarify the correspondence between the component points generated in the three-dimensional CAD design data as described above and the component points of the construction management data corresponding thereto. The code | symbol corresponding to is attached | subjected.

  Next, the finished shape measurement data receiving means 14 receives the finished shape measurement data obtained by measuring the completed object. The three-dimensional CAD result data generation means 16 generates three-dimensional CAD result data with the constituent points of the result measurement data as the vertices of the polygon. In order to clarify the correspondence between the constituent points in the three-dimensional CAD ready-made data and the corresponding constituent points of the ready-made measurement data, the second identification code assigning means 20 attaches codes corresponding to both.

The comparison means 22 compares the three-dimensional CAD design data with the three-dimensional CAD completed data, and determines whether or not the object is completed as designed.

2. Hardware Configuration FIG. 3 shows a hardware configuration of the finished product management apparatus. A memory 32, a display 34, a hard disk 36, a CD-ROM 38, and a mouse / keyboard 48 are connected to the CPU 30. In the hard disk 36, an operating system (OS) 40 such as WINDOWS (trademark) and a product management program 42 are recorded. The completed form management program 42 performs its function in cooperation with the OS 40.

The OS 40 and the work form management program 42 are the ones recorded on the CD-ROM 44 and installed via the CD-ROM drive 38.

3. FIG. 4 shows a flowchart of a work form management program according to an embodiment of the present invention. The CPU 30 takes in the three-dimensional CAD design data generated using the three-dimensional CAD program via the CO-ROM drive 38 (step S1). FIG. 6 shows an example of three-dimensional CAD design data when the construction target is embankment. As shown in the figure, the three-dimensional CAD design data is composed of polygons. In this embodiment, the center line CL of the embankment is included in the three-dimensional CAD design data.

  Next, the CPU 30 extracts the center line CL from the captured three-dimensional CAD design data (step S2). Note that when the center line CL is not drawn in the three-dimensional CAD design data, the operator may input with the mouse / keyboard 48. Alternatively, it may be automatically calculated so that the center line CL comes to the center of the upper flat surface of the embankment.

  Next, the operator inputs a cross section (measurement target cross section) to be measured by the total station on the three-dimensional CAD design data using the mouse / keyboard 48 (step S3). In this embodiment, the measurement target cross section is defined as a plane that is horizontal (perpendicular to the horizontal direction) with respect to the vertical (gravity) direction. In FIG. 7a, the upper end lines of the input measurement object cross sections SC1 to SC4 are indicated by broken lines.

  The CPU 30 extracts the intersection point P between the measurement cross section and the outline of each polygon of the three-dimensional CAD design data for each of the measurement target cross sections SC1 to SC4 thus input (step S4). FIG. 8A shows the intersection point P extracted with respect to the measurement target cross section SC2.

  Next, the CPU 30 smoothes the line connecting the intersections thus extracted (step S5). In this embodiment, as shown in FIG. 9A, if the angle θ formed by the adjacent lines LN1 and LN2 across the intersection Pt is within a predetermined angle range with respect to 180 degrees (for example, 170 degrees to 190 degrees). As shown in FIG. 9B, the intersection point Pt is deleted and the line is drawn again.

  By repeating this process, as shown in FIG. 8B, intersections P1 to P4 important for representing the shape of the construction object are extracted. The CPU 30 adds the extracted intersections as the configuration points P1 to P4 to the three-dimensional CAD design data (see FIG. 7b). Note that configuration points are added in the same manner in the other cross sections to be measured.

  Next, the CPU 30 generates TS input data (construction management data) as shown in FIG. 10 from the center line CL and the constituent points of each measurement target cross section (step S6). In this TS input data, each cross section to be measured is specified by the distance from the start point SP of the center line CL. Further, the constituent points in each cross section to be measured are identified by the names L1, L2... On the left side of the center line when viewed from the starting point SP, and the names R1, R2. Is done.

  Subsequently, the CPU 30 gives a name for identification to each constituent point added to the three-dimensional CAD design data (step S7). The names of the constituent points are generated by combining the above-mentioned L1, L2,..., R1, R2... With the distance from the starting point SP of the center line CL. For example, the distance from the start point SP of the center line CL is 30 m, and the constituent point to which R1 is added in the TS input data is assigned the name 30-R1 (see FIG. 11). Other points are similarly named.

  By assigning names according to the rules as described above, it is easy to associate the constituent points of the TS input data with the constituent points of the three-dimensional CAD design data. In addition, by combining the “distance from the start point” and the “number of points on the right side or the left side in the cross section” in this way, a constituent point in any cross section as described later can be easily obtained. Can be encoded.

  The CPU 30 records the generated TS input data on the CD-ROM 46 and outputs it (step S8).

  The TS input data recorded on the CD-ROM 46 is input to the total station for measuring the finished shape. The completed shape of the object measured by the total station is recorded in association with the TS input data. That is, the measurement data (measurement data of each component point) is recorded in association with each component point of the TS input data.

  The CPU 30 acquires the measurement data of the finished shape via the CD-ROM or the like (step S11). The data format of the measurement data is the same as the TS input data in FIG.

  Next, the CPU 30 generates three-dimensional CAD ready-made data by using each component point of the ready-made measurement data as a vertex of the polygon (step S12). FIG. 12 shows the three-dimensional CAD result data generated in this way. Next, the CPU 30 assigns a name to each constituent point in the same manner as the constituent points in the three-dimensional CAD design data (step S13).

  Further, the CPU 30 superimposes the three-dimensional CAD design data and the three-dimensional CAD ready-made data (step S14). At this time, the superposition is performed so that the X coordinates (directions of the center line CL) of the constituent points having the same name coincide with each other.

  The CPU 30 compares the constituent points in the respective measurement target sections SC1 to SC4 with respect to the superimposed three-dimensional CAD design data and three-dimensional CAD ready-made data (step S15). Thereby, the difference between the finished shape and the design value can be calculated.

  Furthermore, in this embodiment, even in a cross section that is not set as a measurement target cross section (for example, an arbitrary cross section SC12 that intersects the center line between the measurement target cross section SC1 and the measurement target cross section SC2), 3D CAD data can be compared.

  This process is performed as follows. First, an arbitrary cross section SC12 is set in the superimposed three-dimensional CAD design data and three-dimensional CAD shape data (see FIGS. 7a and 12). CPU30 extracts the intersection of the polygon outline of three-dimensional CAD design data, and arbitrary cross-section SC12. Further, the lines connecting the intersections are smoothed to determine the constituent points. Similarly, also for the three-dimensional CAD completed data, the constituent points are determined on the arbitrary cross section SC12. The three-dimensional CAD design data obtained in this way is compared with the constituent points of the three-dimensional CAD ready-made data.

  FIG. 13 shows a comparative example. In the figure, black circles are 3D CAD design data, and white circles are 3D CAD ready-made data. The CPU 30 compares the position of each component point, the length of the slope connecting between the component points (slope length), the horizontal distance (width) between the component points constituting the road surface and the steps, and the like. For example, when the constituent point 100 of the three-dimensional CAD design data is compared with the constituent point 200 of the corresponding three-dimensional CAD ready-made data, it is performed as follows. In addition, since the same name (30-R4) is attached | subjected to the component point 100 and the component point 200, it can recognize easily that both correspond.

  First, the CPU 30 calculates distances (CL separation) CLDd and CLDr from the center line CL for each of the configuration points 100 and 200. Next, the CPU 30 calculates the heights Hd and Hr for the constituent points 100 and 200, respectively. The degree of deviation of the CL separation CLDr and the height Hr in the finished shape from the CL separation CLDd and the height Hr, which are design values, is calculated. The above comparison is made for all components.

  Next, the design value Ld and the finished shape value Lr are compared with respect to the distance (law length) between adjacent constituent points. That is, how much the design value Ld deviates from the shape value Lr is calculated. The CPU 30 compares all the legal lengths.

  As described above, in this embodiment, it is possible to manage the finished shape for a cross section other than the cross section to be measured. Thereby, for example, it becomes easy to perform total number management.

The CPU 30 outputs the above comparison result from a printer (not shown) as a finished product management form (step S16).

4). Other embodiments
(1) In the above embodiment, the lines connecting the intersections are smoothed, and the number of intersections is reduced to form the constituent points. However, all intersections may be compared as constituent points.

(2) In the above embodiment, three-dimensional CAD ready-made data is generated only from the constituent points of the ready-made measurement data. However, it is also possible to superimpose the three-dimensional measurement data obtained by laser or the like and the measurement data obtained from TS or the like, and use both data as the vertexes of the polygon to obtain the three-dimensional CAD production data.

(3) In the above-described embodiment, three-dimensional CAD ready-made data is generated from the constituent points of the ready-made measurement data (skeleton data measured by the TS). However, three-dimensional CAD ready-made data may be generated using the points of the three-dimensional ready-made measurement data obtained by a laser or the like without using the ready-made measurement data. In this case, the superimposition of the 3D CAD design data and the 3D CAD model data is X, Y, Z coordinates (for example, the origin of the 3D CAD design data is matched with the origin of the 3D CAD model data). Can be done based on.

(4) In the above embodiment, the three-dimensional CAD design data and the three-dimensional CAD ready-made data are compared. However, the constituent points of the TS input data (construction management data) may be compared with the constituent points of the three-dimensional CAD ready-made data.

(5) In the above embodiment, TS input data is generated based on the three-dimensional CAD design data, three-dimensional CAD ready-made data is generated based on the ready-made measurement data, and both are compared. However, three-dimensional measurement data may be acquired by laser measurement or the like, and the three-dimensional measurement data may be compared with the three-dimensional CAD design data. In this case, the intersection of the polygon outline of the three-dimensional CAD design data and the cross section is acquired at a predetermined cross section that intersects the center line, and this is smoothed to obtain the composition point. Similarly, constituent points are acquired for the three-dimensional measurement data. Then, the constituent points of the three-dimensional CAD design data are compared with the constituent points of the three-dimensional measurement data.

(6) In the above embodiment, the center line determination means extracts and determines the center line from the three-dimensional CAD design data. However, the center line may be automatically determined based on the width of the object (such as the center of the road width) in the three-dimensional CAD design data. Alternatively, the user may input with a mouse or the like, and the center line determination means may determine based on the input.
