Description

  The present invention relates to a three-dimensional shape display device, and more particularly to a three-dimensional shape display device that displays a three-dimensional shape based on predetermined data.

  Conventionally, in the field of real estate development and the like, it is possible to acquire highly accurate three-dimensional coordinate data in a short time by scanning the ground surface to be measured using laser light. For example, a three-dimensional laser range Scanners, 3D photogrammetry devices, and the like (hereinafter abbreviated as 3D scanners) are widely used. In recent years, the data acquired by these 3D scanners greatly contributes to CAD (Computer Aided Design) drawing and visualization using Geographic Information System (GIS). Widely used in each process such as management.

  On the other hand, the shape of the land seen through drawings and displays is somewhat deviated from the image when the actual land is seen. Therefore, when actually planning a real estate development, the visual image is the object of development. For example, paper or resin is used to produce a three-dimensional model closest to the land shape, and a plan based on this three-dimensional model is made. However, since this type of three-dimensional model takes a long time to produce, there is an inconvenience that an enormous design cost is required and that it is difficult to correct the plan change. In addition, when comparing the current land shape with the land shape completed by real estate development, it is necessary to produce a plurality of three-dimensional models, which further increases the design time and design cost.

  In addition, as a device that expresses a three-dimensional shape using data related to land, a device that expresses the surface shape of the land by the tip portions of a plurality of rods arranged in a matrix has been proposed (Patent Document 1). reference). However, this device is not sufficient to compare different land shapes, specifically, to visually compare the current land shape with the completed land shape, and the rod while comparing both shapes. If the land shape is changed by intentionally moving the data, it is not sufficient to obtain data on the change.

Next, the processing device 60 a drives the hydraulic unit 70 while monitoring a signal transmitted from the piezo element 42 provided in the gripping mechanism 40 corresponding to the first modeling pins 30 _{1, 1} to 30 _{1, 14.} Then, as shown in FIG. 9, each first lifter pin 161 is raised based on the first data D <_{b> 1} 1, 1 to D <_b> 1 _1, 14. Thus, the first modeling pin ₃₀ 1,1 _{30 1, 14} is positioned in a position based on the first data _D1 1,1 _{~ D1 1,14.}

Next, the processing device 60 a applies a voltage to the piezo element 42 of the gripping mechanism 40 corresponding to the first modeling pins 30 _{1, 1} to 30 _{1, 14} to position the first modeling pins 30 _{1, 1} to _Grip 30 1, ₁₄ each. As a result, the position of the first modeling pin 30 in the first row is fixed.

Then, the processing unit 60a is directly below the second modeling pin ₃₅ 1,1 _{35 1,14} arranged in the first row, so that each second lifter pin 162 is positioned to move the cylinder unit 150 , as shown in FIG. 10, each of the second lifter pin 162 is raised on the basis of the second data _D2 1,1 _{~D2 1,14.} Thus, the second modeling pin ₃₅ 1,1 _{35 1, 14} is positioned in a position based on the second data _D2 1,1 _{~ D2 1,14.} Then, a voltage is applied to the piezo element 42 of the gripping mechanism 40 corresponding to the second modeling pins 35 _{1, 1 to} 35 _{1, 14} , and the positioned second modeling pins 35 _{1, 1 to} 35 _{1, 14} are respectively applied. Grab. Thereby, the position of the second modeling pin 35 in the first row is fixed.

Based on the first data D1 and the second data D2, the above-described operation is performed based on the first modeling pins 30 _{2, 1} to 30 _{14, 14} and the second modeling pins 35 arranged in the second and subsequent rows. _{2, 1 to} 35 ₁₄ , ₁₄ , the curved surface S 1 defined by the first modeling pin 30 and the curved surface S 2 defined by the second modeling pin 35 are displayed as shown in FIG. Is done.

  As described above, the three-dimensional shape display device 10 according to the present embodiment includes a plurality of first modeling pins 30 that are two-dimensionally arranged in a matrix in a vertically movable state, and the interior of the first modeling pins 30. The second modeling pin 35 is provided so as to be slidable in the vertical direction. Then, based on the first data D1 corresponding to the first modeling pin 30, each first modeling pin 30 is positioned by the positioning device 100, and based on the second data D2 corresponding to the second modeling pin 35, By positioning the second modeling pins 35 by the positioning device 100, the curved surface S1 defined by the first modeling pin 30 and the curved surface S2 defined by the second modeling pin 35 are displayed simultaneously. Therefore, it is possible to easily compare the difference between the curved surfaces S1 and S2.

  Specifically, the development target land data acquired by the 3D scanner or the like is used as the second data D2, and the development target land data acquired by the 3D scanner or the like is used as the first data D1. By using the changed design data, the land shape to be developed can be displayed by the second modeling pin 35 and the land shape to be planned by the first modeling pin 30 can be displayed. It is possible to visually grasp the difference. In addition, since different shapes can be easily displayed by changing the contents of the data D1 and D2, for example, the shape can be easily and quickly compared with the case of producing a three-dimensional model based on the data. The difference can be displayed.

  In the present embodiment, since the first modeling pin 30 is made of a transparent plastic material, the second modeling pin 35 is positioned inside the first modeling pin 30 as shown in FIG. Even when there is a portion, the second modeling pin 35 can be visually recognized well.

  In addition to the first modeling pin 30, a transparent material is similarly used for the material of the second modeling pin 35. For example, as shown in FIG. 11, the upper surface of the support plate 24 and the upper end of the frame 23 are supported, for example. By providing the laser device 170 that can be moved up and down along the column 171, a contour line and a plan change line are formed inside the modeling pins 30 and 35 by the laser beam LB emitted in the horizontal direction from the laser device 170. , Indication lines, etc. can be specified.

  A plurality of laser devices 170 may be provided on the support pillar 171 or may be provided at a plurality of locations such as the support plate 24. In addition, by irradiating laser beams of different colors for each laser device 170, it is possible to improve the visibility of contour lines and the like.

  In addition, instead of using the laser device 170 described above, a light emitting material such as a light emitting diode is assembled at the upper end of each of the modeling pins 30 and 35, and contour lines, plan change lines, instruction line plans, etc. are clearly indicated in the same manner. You may do it.

  Further, as described above, the gripping force of the first modeling pin 30 and the second modeling pin 35 by the gripping mechanism 40 can be finely adjusted to a desired magnitude by the voltage applied to the piezo element 42. Yes. Therefore, the first modeling pin 30 can be manually moved by setting the gripping force of the first modeling pin 30 by the gripping mechanism 40 to a minimum size that can withstand the weight of the first modeling pin 30. It becomes. Then, by measuring the amount of movement of the first modeling pin 30 according to this manual by the signal from the piezo element 42, the amount of movement can be reflected in the design data in real time and displayed on the monitor 60c.

  Note that the land data to be developed obtained with a 3D scanner or the like is necessarily used as the second data D2, and the land data to be developed obtained with a 3D scanner or the like is changed as the first data D1. It is not necessary to use the design data that has been obtained, and the development data obtained by using the 3D scanner or the like as the second data D2 using the data of the land to be developed obtained by the 3D scanner or the like as the first data D1. You may use the design data which changes the data of the target land. However, as for the modeling pins 30 and 35, the first modeling pin 30 is easier to move manually, so the current state of the land to be developed is displayed by the second modeling pin 35, and the displayed shape is displayed. Based on the above, it is desirable to change the shape of the design data.

Further, in the present embodiment, the data _D1 1, 1 _{~ D1 14, 14} and 196 corresponding to the first modeling pin 30 (= 14 × 14), 196 corresponds to the second modeling pin 35 (= 14 × 14) was used for data _D2 1, 1 _{~ D2 14, 14,} for example, when using the data of the corresponding 784 to the line 28 28 column, in a pre-processing apparatus 60a or the like, with adjacent example four data The average values of 196 are calculated, and these values are used as data D1 _{1, 1} to D1 _{14, 14} or data D2 _{1, 1 to} D2 ₁₄ , ₁₄ , and the modeling pins 30 and 35 may be moved.

  In the present embodiment, the description has been given using the shape display device 20 including the first modeling pins 30 and the second modeling pins 35 arranged in a matrix of 14 rows and 14 columns, but this is for convenience of description. For example, the three-dimensional shape display device 10 may include the shape display device 20 including the modeling pins 30 and 35 corresponding to, for example, about 100 rows and 100 columns or more. It is.

  In this embodiment, the movement amount of the modeling pins 30 and 35 is detected using the piezo element 42. However, the movement amount of the modeling pins 30 and 35 is not limited to this, and a known rotary encoder or linear encoder is used. May be detected. Further, the modeling pins 30 and 35 may be positioned while monitoring the movement amount of the lifter pins 161 and 162 instead of the modeling pins 30 and 35.

  In the present embodiment, the piezo element 42 of the gripping mechanism 40 is used as a means for adjusting the gripping force of the gripping mechanism 40 and also as a means for measuring the amount of movement of the modeling pins 30 and 35. As a result, the structure of the apparatus is simplified compared to the case where the gripping force adjustment mechanism and the measurement mechanism for the modeling pins 30 and 35 are provided separately, and it is possible to avoid the increase in size and cost of the apparatus.

  Further, the gripping mechanism 40 that grips the modeling pins 30 and 35 is an example, and other gripping mechanisms may be used. In short, the positions of the first modeling pin 30 and the second modeling pin 35 are fixed based on the corresponding data, so that the two types of curved surfaces S1 and S2 may be displayed in a comparable manner.

  In the present embodiment, the positioning device 100 includes a cylinder unit 150 that moves in the Y-axis direction. Therefore, the configuration of the device is simplified as compared with the case where an elevating mechanism is provided for each of the modeling pins 30 and 35, and as a result, the size and cost of the device can be reduced.

  Moreover, in this embodiment, although the 1st modeling pin 30 and the 2nd modeling pin 35 were moved to the up-down direction by the positioning device 100 using hydraulic pressure, it is not restricted to this, The positioning device 100 is other than air pressure or oil. You may operate using the pressure of a liquid. Further, instead of the hydraulic mechanism, each of the lifter pins 161 and 162 may be moved up and down using a driving device such as a linear motor, an ultrasonic motor, or a piezo walking drive. By the way, as shown in FIG. 11 as an example, the piezo walking drive is configured such that one end of a plurality of element groups 200 including a different set of piezo elements is brought into contact with an object such as a lifter pin, for example. This is a mechanism that lifts and lowers the lifter pin and the like by applying different voltages to each piezoelectric element.
