  At the construction work site, grasping the finished shape at the construction stage is very important because the effect on the post-process can be confirmed quickly. In particular, the finished shape in underground construction often has a very significant effect on subsequent processes. Also, the finished shape of the ground surface of the surface finishing material such as wall material and ceiling material is important because it affects the appearance of the surface finishing material.

   Therefore, conventionally, a method has been used in which a total station or the like is used as a means for grasping the finished product shape, and surveying is performed for each point at a construction site.

(First embodiment)
Next, the best first mode for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, an example of measuring the foundation surface and the finished surface around the basement in a basement construction when disassembling a building having a basement to construct a new building is measured with a three-dimensional laser scanner. I will give you a description. Here, the inner surface of the underground outer wall of the existing building is a finished surface.

  FIG. 1 is an overall plan view showing a measurement state of a finished surface of the best first embodiment for carrying out a construction plan changing method using a three-dimensional laser scanner according to the present invention, and FIG. 2 is a three-dimensional view. A top-down view showing the surface of the building site measured using the laser scanner, and FIG. 3 shows a state in which the core is synthesized and input to the surface of the building site measured using the 3D laser scanner. 4 is a view from which a part of the finished mold surface of FIG. 3 is deleted, FIG. 5 is a view of FIG. 4 viewed from the front, FIG. 6 is a view of FIG. 5 from an oblique side, and FIG. FIG. 6 is a diagram showing the outer peripheral surface of the building, FIG. 8 is a diagram showing the interference between the outer peripheral surface of the building and the finished mold surface, FIG. 9 is a diagram showing the moving direction of the building plan surface, and FIG. The best first implementation for implementing the architectural plan change method using the three-dimensional laser scanner according to the invention Flowchart showing the embodiment. FIG. 11 is a schematic diagram showing the best of the first embodiment for carrying out the architectural plan change device using a three-dimensional laser scanner according to the present invention.

  As shown in FIG. 1, the three-dimensional laser scanner 1 irradiates a measurement object 2 (in this embodiment, the inner surface 15 of the underground outer wall of an existing building) with laser light 3, and the laser light 3 is measured. The distance is calculated from the time until it returns after being reflected by the object 2, and the three-dimensional coordinates (x coordinate, y coordinate, z coordinate) is calculated. The laser beam 3 is irradiated radially at a predetermined angular pitch within a range of 360 degrees in the horizontal direction and 320 degrees in the vertical direction, for example, and the three-dimensional laser scanner 1 collects each reflection point as point cloud data. Thus, the measurement object 2 can be displayed three-dimensionally. The irradiation range of the laser beam 3 is appropriately set according to the shape of the measurement object 2. That is, for example, when measuring the shape of a room in a room, the vertical direction is irradiated with laser light in a range of 320 degrees centering on the top so that the floor and ceiling can also be scanned. Thereby, it is possible to scan everything except the foot of the three-dimensional laser scanner 1. Moreover, when measuring the topography of an outdoor mountainous area or a trough, a laser beam is not irradiated upward. The irradiation pitch of the laser beam 3 is appropriately determined depending on the resolution of the required three-dimensional data. The irradiation pitch is determined by the irradiation angle pitch of the laser light 3, and is set to be, for example, 2 mm apart 10 meters away. When the irradiation angle pitch is small, a lot of laser light 3 is irradiated, the distance between the reflection points becomes small, and the resolution becomes high.

  First, a construction plan changing device used for implementing a construction plan changing method using the three-dimensional laser scanner according to the present embodiment will be described. As shown in FIG. 11, the construction plan changing device 40 is a three-dimensional model of the finished surface 10 (see FIG. 2) of the building site measured as point cloud data 5 using the three-dimensional laser scanner 1 (see FIG. 1). Point cloud data fetching means 41 for fetching data, information data fetching means 43 for synthesizing and inputting construction plan information data 20 such as design drawings and construction drawings, etc. to the fetched point cloud data 5, and the input type The distance between the surface 10 and the construction plan surface 23 (see FIG. 7) determined from the construction plan information data 20 is compared, and the interference portion 30 where the finished surface 10 and the construction plan surface 23 interfere is detected as three-dimensional data. Interference part detection means 44 and interference part volume calculation means 45 for calculating the volume of the interference part 30 are provided. Moreover, the construction plan changing device 40 calculates and compares the volume of the interference part 30 while moving the construction plan surface 23 on the three-dimensional data, and places the construction plan surface 23 at a position where the volume of the interference part 30 is minimized. The construction plan plane moving means 46 to be moved is provided. The construction plan changing device 40 further includes image processing means 47 that performs image processing on the inputted point cloud data 5 and construction plan information data 20 of the finished surface 10 and displays them as images.

  The architectural plan changing device 40 is composed of a computer 6 such as a personal computer or a workstation, and is connected to a surveying instrument such as a three-dimensional laser scanner 1 or a total station (not shown). The construction plan changing device 40 has a function of displaying the captured point cloud data 5 and the inputted construction plan information data 20 on the monitor 7 in a three-dimensional manner. The architectural plan changing device 40 has storage means (not shown) for storing the point cloud data 5 and the architectural plan information data 20. The storage means may be built in the architectural plan change device 40 or may be provided separately and connected to the outside.

  The point cloud data capturing unit 41 has a function of capturing the point cloud data 5 measured by the three-dimensional laser scanner 1 and storing it in the storage unit or reading it from the storage unit. The point cloud data capturing means 41 can also capture data measured by the total station.

  The information data capturing means 43 is means for capturing the architectural plan information data 20 such as design drawings and construction drawings as CAD data, and is based on the finished surface 10 and the building on the basis of the wick printed on the construction site. It has a function of collating and combining with the plan information data 20. The information data fetching means 43 reads the building plan information data 20 into the computer from another connected computer or a data storage means such as a CD-ROM.

  The interference part detection means 44 calculates, for example, the position of the outer peripheral surface 22 (building plan surface 23) of the building based on the building plan information data 20, and determines the interference part 30 between the outer peripheral surface 22 and the finished mold surface 10. To detect.

  The interference part volume calculating means 45 calculates the volume of the interference part 30 from the coordinates of the finished mold surface 10 and the outer peripheral surface 22 of the interference part 30.

  The architectural plan plane moving means 46 moves the entire building virtually in the horizontal direction or rotates it so that the volume of the interference portion 30 is the smallest or the portion where the interference portion 30 disappears. Then, the construction plan plane 23 is moved to the position as the layout position of the building. On the monitor 7, the total value of the volume of the interference portion 30 is displayed. In the present embodiment, the construction plan plane moving means 46 automatically detects the smallest part of the volume of the interference part 30 and determines the movement position.

  The image processing means 47 performs image processing on the steps of the respective means executed in the computer 6 (see FIG. 1) and displays them on a monitor 7 (see FIG. 1) provided integrally or separately with the computer 6. To do. The image processing means 47 includes, for example, a finished surface display means for displaying the point cloud data 5 of the finished mold surface 10 in a three-dimensional manner (see FIG. 2) while looking down from above, and a point cloud data 5 In addition, a street core display means for displaying the street core 21 together (see FIG. 3), and an architectural plan surface 23 such as the outer peripheral surface 22 of the building from the inputted construction plan information data 20 is displayed as an image on the point cloud data 5. (Refer to FIG. 7). The image processing unit 47 can display an image from an arbitrary angle by rotating the image (see FIGS. 5 and 6). Further, as shown in FIG. 8, the image processing unit 47 displays the interference portion 30 in different colors and displays the distance between the completed surface 10 and the outer peripheral surface 22 calculated from the coordinates of each portion of the interference portion 30 and the interference portion. Thirty volumes can also be displayed.

  Next, a construction plan changing method using the three-dimensional laser scanner according to the present embodiment will be described based on the flowchart shown in FIG.

  In such a construction plan changing method, first, the finished surface 10 (see FIGS. 2 to 9) around the foundation and the basement (when there is no basement) is scanned with the three-dimensional laser scanner 1 (see FIG. 1). (Step 1). Scanning is performed in a plurality of times so as not to leave behind unmeasured parts. In addition, when there is no obstacle and all the measurement objects can be measured at one time, one scanning is sufficient. The finished mold surface 10 is three-dimensionally measured using the three-dimensional data as point cloud data 5 by scanning. The measured point cloud data 5 is input to the construction plan changing device 40 (see FIGS. 1 and 11) configured by the computer 6 (see FIG. 1) and the like via the point cloud data capturing means 41, The image is processed by the image processing means 47 and displayed three-dimensionally on the monitor 7. As shown in FIG. 2, the finished mold surface 10 is three-dimensionally shown as a look-down view. The direction shown in the figure can be freely changed. In the present embodiment, the finished surface 10 is the inner surface of the underground outer wall of an existing building that has been demolished, and is formed of, for example, reinforced concrete. A column 12 and a beam 13 protrude from the wall 11 on the finished surface 10. The wall 11 is provided with an erection material 14 that supports the wall 11.

  Next, the building plan information data 20 is taken into the computer via the information data fetching means 43 (see FIG. 11) of the building plan changing device 40 and is synthesized and inputted into the point cloud data 5 (Step 2 (see FIG. 10). )). As shown in FIG. 3, the construction plan information data 20 is various information that can be read from a drawing such as a street core 21 and a distance from the street core 21 of the outer peripheral surface 22 of the building (see FIG. 7). As shown in FIG. 3, a core 21 is shown on the monitor.

  Here, in order to make the point cloud data 5 which is actual measurement data collate with the position of the core 21 which is the construction plan information data 20, the following procedure is performed. First, the wicks are marked on the construction site, and at least two points of the wicks are measured using a total station (not shown). Then, a reference point (not shown) of the finished mold surface 10 is measured without moving the total station. As a result, the position of the core 21 from the reference point can be specified, and the positional relationship between the finished mold surface 10 and the core 21 can be determined by combining the reference point measured by the total station and the reference point in the finished mold surface 10. The position of the building plan information data 20 is collated with the finished mold surface 10 by synthesizing the building plan information data 20 with the core 21 as a reference.

  In addition, the procedure for collating the position of the core 21 which is the construction plan information data 20 with the point cloud data 5 is not limited to the above procedure, and may be the following procedure. At least two measuring objects (for example, a reference sphere, a hemisphere, a cone, a checkerboard pattern, etc.) that can be measured with a three-dimensional laser scanner on each of the street cores crossed with each other among the street cores printed on the construction site. When installed, the position of the core is also measured at the same time when scanning with a 3D laser scanner. According to this, it is possible to measure the position of the core 21 with respect to the finished mold surface 10 only by scanning the three-dimensional laser scanner without using a total station. The building plan information data is based on the core 21. By combining 20, the position of the building plan information data 20 is collated with the finished mold surface 10.

  Next, in order to rotate the display direction of the finished mold surface 10, as shown in FIG. 4, a part of the finished mold surface 10 is deleted by the image processing means 47 (see FIG. 11) of the architectural plan changing device 40. . As a result, the data amount of the point cloud data 5 to be displayed is reduced, so that the display speed can be increased. As shown in FIG. 5, if the finished mold surface 10 is displayed from the front to the side, or the finished mold surface 10 is displayed obliquely as shown in FIG. This is preferable because the current state of the finished surface 10 can be grasped in a three-dimensional manner, and in particular, a shift in the vertical direction can be confirmed.

  Thereafter, the image processing means 47 (see FIG. 11) of the architectural plan changing device 40, as shown in FIG. 7, shows the building at a position separated from the core 21 by a predetermined distance based on the inputted architectural plan information data 20. An architectural plan surface 23 such as the outer peripheral surface 22 is displayed.

  Here, the distance between the finished surface 10 and the outer peripheral surface 22 of the building is compared by the interference part detecting means 44 (see FIG. 11) of the construction plan changing device 40, and the finished surface 10 and the building plan surface 23 are compared. The interference portion 30 is detected (Step 3 (see FIG. 10)). At this time, it can be seen from the building plan information data 20 that the outer peripheral surface 22 of the building is at a position offset by a predetermined distance outward from the core 21. Then, the outer peripheral surface 22 is virtually displayed at the position as shown in FIG. 7 by the image processing means 47 (see FIG. 11). Here, the part which protrudes from the outer peripheral surface 22 becomes the interference part 30, and the interference part 30 can be visually recognized at a glance. Further, the image processing means 47 can display the outer peripheral surface 22 (architectural planning surface 23) so as to be transmitted, and display the interference portion 30 by color (indicated by hatching H0 in FIG. 7). According to this, the finished surface 10 outside the outer peripheral surface 22 (architectural plan surface 23) can also be grasped at a glance. Further, the distance between the finished mold surface 10 and the outer peripheral surface 22 of the building can be displayed on the image, and the tilted state of the finished mold surface 10 can be grasped at a glance. Therefore, it can be used as a guide when the outer peripheral surface 22 is moved by manually inputting a moving direction or a numerical value.

  Next, the volume of the interference part 30 is calculated by the interference part volume calculating means 45 (see FIG. 11) of the construction plan changing device 40 (Step 4 (see FIG. 10)). The volume calculated here is displayed on the image as shown in FIG.

  Then, the construction plan plane moving means 46 (see FIG. 11) of the construction plan changing device 40 calculates and compares the volume of the interference portion 30 while moving the construction plan plane 23 (Step 5 (see FIG. 10)). The construction plan surface 23 is moved to a position where the volume of the interference portion 30 is minimum or zero (Step 6 (see FIG. 10)). At this time, as shown by the arrows in FIG. 9, the construction plan plane 23 is moved horizontally up and down, left and right, or rotated to search for a portion where the volume of the interference portion 30 is minimized. In FIG. 9, the upper and right pillars 12 in the figure have a lot of interference with the construction plan surface 23, so the entire building may be moved to the lower left side in the figure. The moving position is determined automatically by the construction plan plane moving means 46, where the volume of the interference part 30 is minimized. The operator manually moves while viewing the volume display of the interference part 30. You may make it move the construction plan surface 23 on a screen, inputting a direction, a rotation direction, and a numerical value.

  In the present embodiment, the position where the volume of the interference portion 30 is the minimum is set as the movement position of the building plan surface 23, but the present invention is not limited to this. For example, when many rebars are arranged in the interference portion 30 or a very hard rock is located, the cutting work for removing the interference portion 30 is very difficult, and therefore the construction is difficult. The movement position of the construction plan surface 23 may be determined so that the portion where it is difficult to avoid or the construction is difficult is minimized. In this case, if a portion that is difficult to construct is input as additional data to the point cloud data 5 of the finished surface 10, the movement position of the construction plan surface 23 can be automatically determined based on the data.

  Then, a building is constructed at the position determined by the above process.

  According to the construction method using the three-dimensional laser scanner as described above, since the finished surface 10 is measured using the three-dimensional laser scanner 1, highly accurate point cloud data 5 is converted into a three-dimensional form. It can be obtained in a short time as three-dimensional data. Since the building plan information data 20 is also input as CAD data, the building can be grasped as three-dimensional data. Therefore, the interference portion 30 between the finished mold surface 10 and the building plan surface 23 can be detected three-dimensionally. As a result, the interference portion 30 can be detected according to the actual finished surface 10, so that it is also possible to detect the interference portion at the top that cannot be detected simply by searching for the interference portion in a planar manner as in the prior art. In particular, the present invention is very effective when the finished mold surface 10 is inclined in the vertical direction or only the upper part protrudes.

  And since the volume of the interference part 30 is calculated, the cutting amount of the finished mold surface 10 can be reduced, and a work period can be shortened. Further, when dismantling an existing building and constructing a new building, the amount of reinforcing bars inside the finished surface 10 can be grasped, so that a portion where removal (cutting) construction is difficult can be grasped. . If the moving position of the building is determined so as to avoid such a part, the labor of construction can be reduced and the construction period can be shortened. In addition, according to the present invention, the specific cutting amount of the finished mold surface 10 can be specifically grasped as a volume, so that a highly accurate process can be assembled and the influence on the subsequent process can be eliminated.

  Further, according to the present invention, the construction plan plane 23 is virtually moved in the construction plan change device 40, and the movement position is determined so that the volume of the interference portion 30 is reduced. The optimum position can be determined. Therefore, since it is not necessary to make a major change after the start of the frame construction, it is possible to prevent a delay in the construction period. In addition, changes that cannot be selected after the start of the frame construction (changes in the position of the building, changes in the shape of the frame, etc.) can be selected prior to the construction stage, making it possible to make an optimal architectural plan change. Construction cost and construction time can be greatly reduced. Furthermore, the movement position of the construction plan surface 23 can be determined automatically and at high speed by the construction plan change device 40, and efficient construction can be performed, so that the construction period can be shortened.

  Furthermore, in this Embodiment, since the outer peripheral surface 22 of a building is displayed and the interference part 30 is color-coded and the interference part 30 can be visually recognized three-dimensionally, the movement position of the construction plan surface 23 and a subsequent construction process Can be grasped as an image.

(Second embodiment)
Next, the second best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, a case where the completed surface of the lower ground of the ceiling is measured with a three-dimensional laser scanner will be described as an example. In the present embodiment, a ceiling material using a cone-shaped wave absorber used in an anechoic chamber or the like serves as a surface finishing material. When a cone-shaped wave absorber is used as a ceiling material, radio waves are reflected between the cones and absorbed, so that the flatness of the surface of the base material that affects the angle of the cone is important. In the present embodiment, the finished mold surface is the surface of the base material deformed by a fire or the like. In the case of an anechoic chamber, the base material is often composed of an iron plate having the ability to shield radio waves.

  First, a construction plan changing device used for implementing a construction plan changing method using the three-dimensional laser scanner according to the present embodiment will be described. As shown in FIG. 16, the construction plan changing device 40 ′ is a building surface finished surface 10 ′ measured as point cloud data 5 ′ (not shown) using the three-dimensional laser scanner 1 (see FIG. 1). Point cloud data fetching means 41 for fetching three-dimensional data (see FIG. 2) and information data fetching means for combining and inputting architectural plan information data such as design drawings and construction drawings into the fetched point cloud data 5 ′ 43 is compared with the distance between the inputted finished surface 10 ′ and the building plan surface 23 ′ (see FIG. 14) determined from the building plan information data, and the gap 31 between the finished surface 10 ′ and the building plan surface 23 ′ is compared. Is detected as three-dimensional data, a gap volume calculating means 51 for calculating the volume of the gap 31, and a building plan surface 23 '(FIG. 14) determined from the input surface 10' and the building plan information data. Distance) In comparison, the interference part detecting means 44 for detecting the interference part 30 'where the finished surface 10' and the building plan surface 23 'interfere as three-dimensional data, and the interference part volume calculation for calculating the volume of the interference part 30'. Means 45. Moreover, the construction plan changing device 40 calculates and compares the volume of the interference part 30 while moving the construction plan surface 23 on the three-dimensional data, and places the construction plan surface 23 at a position where the volume of the interference part 30 is minimized. The construction plan plane moving means 46 to be moved is provided. The construction plan changing device 40 further includes image processing means 47 that performs image processing on the inputted point cloud data 5 and construction plan information data 20 of the finished surface 10 and displays them as images.

  As in the first embodiment, the construction plan changing device 40 is configured by a computer 6 such as a personal computer or a workstation, and is a surveying instrument such as a three-dimensional laser scanner 1 or a total station (not shown). It is connected. The construction plan changing device 40 ′ has a function of displaying the captured point cloud data 5 ′ and the inputted construction plan information data on the monitor 7 in a three-dimensional manner. The architectural plan changing device 40 ′ has storage means (not shown) for storing point cloud data 5 ′ and architectural plan information data. The storage means may be built in the building plan changing device 40 'or may be provided separately and connected to the outside.

  The point cloud data capturing unit 41 has a function of capturing the point cloud data 5 ′ measured by the three-dimensional laser scanner 1 and storing it in the storage unit or reading it from the storage unit. The point cloud data capturing means 41 can also capture data measured by the total station.

  The information data capturing means 43 is means for capturing architectural plan information data such as design drawings and construction drawings as CAD data. The construction plan information data includes the core, the type and dimensions of each member, and the ceiling height and ceiling material 25 (surface finishing material) from the construction plan information data input by the information data fetching means 43. The thickness of can be grasped.

  For example, the gap detection means 50 calculates the position of the base-side back surface 26 of the ceiling material 25 from the ceiling height of the room and the thickness of the ceiling material 25 (surface finishing material) grasped based on the building plan information data. A gap 31 between the base-side back surface 26 of the ceiling material 25 and the finished mold surface 10 ′ (the surface 28 of the base material 27) is detected.

  The gap volume calculation means 51 calculates the volume of the gap 31 from the coordinates of the finished mold surface 10 ′ of the gap 31 and the base-side back surface 26 of the ceiling material 25.

  On the other hand, the interference part detection means 44 calculates the position of the base-side back surface 26 of the ceiling material 25 from the ceiling height of the room and the thickness of the ceiling material 25 (surface finishing material) grasped based on the building plan information data, for example. Then, an interference portion 30 ′ between the back surface 26 of the ceiling material 25 and the finished mold surface 10 ′ (surface 28 of the base material 27) is detected.

  The interference part volume calculating means 45 calculates the volume of the interference part 30 ′ from the coordinates of the finished surface 10 ′ of the interference part 30 ′ and the base-side back surface 26 of the ceiling material 25.

  The construction plan plane moving means 46 virtually moves the entire ceiling material 25 in the vertical direction, and the portion in which the sum of the volume of the gap 31 and the volume of the interference portion 30 ′ is the smallest is obtained. As the installation height of the ceiling material 25, the base-side back surface 26 (architecture plan surface 23) of the ceiling material 25 is moved to that position.

  The image processing means 47 performs image processing on the steps of each means to be executed in the computer 6 (see FIG. 1), and applies it to the monitor 7 (see FIG. 12) provided integrally or separately from the computer 6. indicate. The architectural plan surface display means includes, for example, a finished surface display means for displaying the point cloud data 5 'of the finished surface 10' while looking down from above (see FIG. 13). The image processing means 47 can rotate and display the image from an arbitrary angle. Further, the image processing means 47 can perform contour display (contour line display) by color-coding the unevenness of the surface 28 of the base material 27.

  Next, a construction plan changing method using the three-dimensional laser scanner according to the present embodiment will be described based on the flowchart shown in FIG.

  In the architectural plan changing method, first, the surface 28 (finished surface 10 ') of the ceiling base material 27 exposed by the three-dimensional laser scanner 1 (see FIG. 12) is scanned (Step 1). Scanning is performed in a plurality of times so as not to leave behind unmeasured parts. In addition, when there is no obstacle and all the measurement objects can be measured at one time, one scanning is sufficient. The unevenness of the finished mold surface 10 ′ is measured three-dimensionally using the three-dimensional data as point cloud data 5 ′ by scanning. The measured point cloud data 5 ′ is input to the construction plan changing device 40 ′ constituted by the computer 6 (see FIG. 1) or the like via the point cloud data fetching means 41, and is imaged by the image processing means 47. It is processed. In the point cloud data 5 ', the unevenness of the surface 28 is contour-displayed on the monitor 7 in a gradation (not shown). In the present embodiment, the finished mold surface 10 'is the surface 28 of the base material 27 made of iron plate deformed by a fire or the like, and has a relatively large unevenness (see FIGS. 13 and 14).

  Next, the building plan information data is synthesized and inputted to the point cloud data 5 'via the information data fetching means 43 (see Fig. 16) of the building plan changing device 40 (Step 2 (see Fig. 14)). Here, the construction plan information data includes the thickness of the ceiling material 25, the ceiling height, and the like, and the height of the base-side back surface 26 (see FIG. 14) of the ceiling material 25 can be specified. In the present embodiment, since the cone-shaped electromagnetic wave absorber becomes the ceiling material 25, the flatness of the surface 28 of the base material 27 is important, but the building plan information data includes the base material in the ceiling material 25. 27 also includes a tolerance 33 for unevenness of the surface 28 of the surface 27. As shown in FIG. 13, the point cloud data 5 ′ is displayed by color-coding the portion outside the allowable range 33. Specifically, a predetermined range above and below the height of the base-side back surface 26 of the ceiling material 25 is displayed in gray as an allowable range 33 (indicated by hatching H1 in FIG. 13). A portion at a position higher than the allowable range 33 is displayed in red (indicated by hatching H2 in FIG. 13), and a portion at a position lower than the allowable range 33 is displayed in blue (indicated by hatching H3 in FIG. 13). Is displayed. The portion 34 that exceeds the contour display range is displayed, for example, in black (displayed in black in FIG. 13). The finished surface 10 'is shown as a look-down view, but the direction shown can be freely changed and can be displayed in three dimensions.

  The contour display range can be freely set. For example, if the contour display range is narrowed, the unevenness of the finished surface 10 'can be displayed finely as shown in FIG. . Note that the reference numerals in FIG. 17 are the same as the reference numerals in FIG.

  Here, the surface (base surface) 28 of the base material 27 and the base material of the ceiling material (surface finishing material) 25 which are the finished mold surface 10 ′ by the gap detecting means 50 (see FIG. 16) of the architectural plan changing device 40 ′. The distance between the side rear surface 26 (architecture plan surface 23 ′) is compared, and a gap 31 between the finished mold surface 10 ′ and the architecture plan surface 23′0 is detected (Step 3 (see FIG. 15)). At this time, as shown in FIG. 14, the architectural plan surface 23 ′ is a layer indicated by an allowable range 33 in which a predetermined value is added or subtracted above and below the ground-side back surface 26 of the actual ceiling material (surface finishing material) 25. In consideration of 33 ′ (indicated by hatching H4 in FIG. 14), the upper and lower end surfaces of the layer 33 ′ are set. In other words, a gap located in the layer 33 ′ within the allowable range 33 is allowed, and the upper end surface of the layer 33 ′ becomes the construction plan surface 23 ′ when the gap 31 is detected. Therefore, a gap positioned above the upper end surface is detected as the gap 31.

  Next, the volume of the gap 31 is calculated by the gap volume calculating means 51 (see FIG. 16) of the architectural plan changing device 40 '(Step 4 (see FIG. 16)). The volume calculated here is displayed on the image.

  At the same time as Steps 3 and 4, the interference part detecting means 44 (see FIG. 16) of the construction plan changing device 40 ′ allows the surface (base surface) 28 (finished surface 10 ′) of the base material 27 and the ceiling material (surface finish). Compare the distance between the base material back surface 26 (architecture plan surface 23 ') of the material 25 and detect the interference portion 30' between the finished mold surface 10 'and the architecture plan surface 23' (Step 5 (see FIG. 15)). ). At this time, as shown in FIG. 14, the architectural plan surface 23 ′ is a layer indicated by an allowable range 33 in which a predetermined value is added or subtracted above and below the ground-side back surface 26 of the actual ceiling material (surface finishing material) 25. 33 ′ (displayed by hatching H4 in FIG. 14) is set. That is, the interference portion located in the layer 33 ′ within the allowable range 33 is allowed, and the lower end surface of the layer 33 ′ becomes the construction plan surface 23 ′ when detecting the interference portion 31 ′. Therefore, the interference part located in the lower part of the lower end surface is detected as the interference part 30 '.

  Next, the volume of the interference part 30 ′ is calculated by the interference part volume calculation means 45 (see FIG. 16) of the building plan changing device 40 ′ (Step 6 (see FIG. 15)). The volume calculated here is displayed on the image.

  Then, the construction plan plane moving means 46 (see FIG. 16) of the construction plan change device 40 calculates and compares the volume of the interference portion 30 ′ while moving the construction plan plane 23 ′ up and down (Step 7 (FIG. 15). In addition, the construction plan surface 23 is moved to a position where the volume of the interference portion 30 is minimum or zero (Step 8 (see FIG. 15)). At this time, a portion where the sum of the volume of the interference portion 30 ′ and the volume of the gap 31 is minimized is searched for. The position is set as the installation height of the ceiling material 25.

  Thereafter, according to the installation height, the interference portion 30 ′ is removed, and a spacer (not shown) is provided in the gap 31 to install the ceiling material 25.

  According to the construction method using the three-dimensional laser scanner as described above, since the finished surface 10 ′ is measured using the three-dimensional laser scanner 1, highly accurate point cloud data 5 ′ is converted into a three-dimensional shape. Can be obtained in a short time as typical three-dimensional data. Then, by detecting the gap 31 and the interference part 30 ′ between the finished surface 10 ′ and the building plan surface 23 ′ and calculating the volume of both, it is possible to eliminate the troubles such as removing the interference part 30 ′ and repairing the spacer. It can be greatly reduced. In particular, when the entire base material 27 is raised upward or lowered downward, the repair work can be greatly reduced only by changing the finishing height of the ceiling material 25, so the present invention is very effective. It is.

  Since the volume of the interference portion 30 ′ is calculated, the cutting amount of the finished mold surface 10 can be specifically grasped as the volume. Furthermore, the shape and the amount of spacers can be accurately grasped. Therefore, a highly accurate process can be assembled, and the influence on the subsequent process can be eliminated.

  Further, according to the present embodiment, the architectural plan plane 23 ′ is virtually moved in the architectural plan change device 40 ′ so that the sum of the volume of the interference portion 30 ′ and the volume of the gap 31 is reduced. Therefore, the optimal position can be determined before the construction stage. Therefore, since it is not necessary to make almost any changes after the ceiling work is started, it is possible to prevent delays in the construction period. In addition, changes that cannot be selected after the ceiling work is started (changes in the installation height of the ceiling material 25, etc.) can be selected before the construction stage, so it is possible to make an optimal architectural plan change, and the construction cost And construction time can be greatly reduced. Furthermore, the moving position of the building plan surface 23 'can be determined automatically and at high speed by the building plan changing device 40', and efficient construction and shortening of the work period can be achieved.

  Furthermore, in the present embodiment, the surface 28 of the base material 27 is contour-displayed and the interference portion 30 ′ and the gap 31 are color-coded, so that the interference portion 30 ′ and the gap 31 can be visually recognized at a glance. The construction process can be grasped as an image.

For example, in the first embodiment, when a building having a basement is dismantled and a new building is constructed, the foundation and the finished surface around the basement are measured with a three-dimensional laser scanner. However, the present invention is not limited to this. For example, even when building a building with a basement or a building without a basement, the surface of the ground excavation surface (including support work) around the basement or the foundation is treated with a 3D laser. The present invention can be applied if measurement is performed using a scanner.

  In the second embodiment, the case where the ceiling material is measured with a three-dimensional laser scanner is taken as an example, but the present invention is not limited to this. Of course, the present invention can also be applied when various surface finish materials are attached to the base surface, such as when the radio wave absorber is provided on the wall surface, or when an outer wall material such as a tile is provided on the wall surface.
