Summary of Invention

Problems to be Solved by the Invention

[0004] In order for a computer to accurately scan the shape of an object or the like, it is necessary to place markers that allow a scanning device to recognize position information at accurate positions along the shape. In general, as in Patent Document 1, a dedicated mounting member provided with markers along the shape is often used.

[0005] However, for large objects and the like, it is difficult and tends to be expensive to produce a dedicated mounting member, so work such as affixing marker stickers and the like one by one at equal intervals to the target object and peeling off the marker stickers one by one after scanning is required, and scanning the shape of an object or the like required long working hours.

[0010] The following matters become clear from this specification and the accompanying drawings:

[0011] A marker setting device comprising: a gripping portion having an up-and-down direction and extending along the up-and-down direction, which joins to the object to be scanned at its first end; a support portion joining to the second end opposite the first end of the gripping portion and extending in a direction intersecting the up-and-down direction; and display units provided at both ends of the support portion and in the center of the support portion for displaying positional information of the object to be scanned, wherein the joining portion at the first end can be attached to and detached from the object to be scanned multiple times.

[0012] Such a marker placement device allows for quick, easy, and repeated use of a marker placement device equipped with multiple display units, thereby streamlining the marker placement process.

[0013] <Regarding the first embodiment> The marker setting device 100 according to the first embodiment will be described with reference to the figures. Figure 1 is a schematic perspective view of the marker setting device 100 according to the first embodiment.

[0014] As shown in Figure 1, the marker setting device 100 according to the first embodiment has a gripping part 1, a support part 10, and a display part 20, and is installed on the upper surface of the object to be scanned X.

[0015] The grip portion 1 is in a rod shape extending along the vertical direction, and has a first end portion 2 and a second end portion 3. The first end portion 2 is placed and fixed on the upper surface of the scan target X. In the first embodiment, a first magnet 2a (see FIG. 3) is provided inside the first end portion 2, and the first end portion 2 is fixed to the scan target X which is a ferromagnetic material (such as a magnet or iron) by the attractive force of the magnet. Therefore, the first end portion 2 of the grip portion 1 can be repeatedly attached to and detached from the scan target X which is a ferromagnetic material many times.

[0016] Further, the grip portion 1 is provided with the second end portion 3 on the side opposite to the first end portion 2 in the vertical direction. The second end portion 3 is joined to the central lower surface of the support portion 10, so that the support portion 10 is supported by the grip portion 1. In the first embodiment, a second magnet 3a (see FIG. 3) is provided inside the second end portion 3, and is fixed by attracting a magnet (not shown) provided inside the central portion of the support portion 10.

[0017] The support portion 10 is supported by the grip portion 1, is in a rod shape, and extends outward from the central portion supported by the grip portion 1 in a direction intersecting the vertical direction. In the first embodiment, the support portion 10 extends to both outer sides (outward at an interval of 180 degrees), and has a first support portion 11 and a second support portion 12 as two support portions 10, and the first support portion 11 and the second support portion 12 are each provided at an interval of approximately 90 degrees.

[0018] The display portion 20 has a circular shape, on which a solid black circle is displayed, and is a part that causes a scanning device (not shown) to recognize the position information of the scan target X. The display portions 20 are provided at a total of five positions, namely both end portions of the first support portion 11, and the central portion and both end portions of the second support portion 12. Note that the display portion 20 is not limited to a circular shape, and may be an elliptical shape, a rectangular shape, or the like, and the display does not need to be a black circle, and any form is acceptable as long as it can be recognized by the scanning device.

[0019] Then, as described above, the marker placement device 100 is fixed to the scan target X by the attractive force of the magnet of the grip portion 1, so for example, after the position information of the display portion 20 of the marker placement device 100 is read by a scanning device, it can be easily removed quickly, and can also be easily attached to other positions of the scan target X.

[0020] That is, the marker placement device 100 according to the first embodiment has a vertical direction, extends along the vertical direction, and includes: a grip portion 1 joined to the scan target X at a first end portion 2; a support portion 10 joined to a second end portion 3 of the grip portion 1 on the side opposite to the first end portion 2 and extending in a direction intersecting the vertical direction; and display portions 20 provided at both end portions of the support portion 10 and a central portion of the support portion 10 and configured to display position information of the scan target X, wherein a joint portion at the first end portion 2 can be attached to and detached from the scan target X multiple times.

[0021] Accordingly, the marker placement device 100 provided with the plurality of display portions 20 can be used repeatedly quickly and easily, so that the marker placement operation can be made more efficient.

[0022] Further, as shown in Figure 1, the first support portion 11 and the second support portion 12 are not located at overlapping positions when viewed from the vertical direction. Accordingly, as the position information of the scan target X, a total of five pieces of position information can be provided, namely two positions of the display portions 20 on the first support portion 11 and three positions of the display portions 20 on the second support portion 12.

[0023] That is, in the marker placement device 100 according to the first embodiment, the support portion 10 has the first support portion 11 and the second support portion 12, and when viewed from the vertical direction, the display portions 20 of the first support portion 11 and the display portions 20 of the second support portion 12 do not overlap with each other.

[0024] Accordingly, since the marker placement device has the plurality of support portions 10 (the first support portion 11 and the second support portion 12) and the respective display portions 20 do not overlap when viewed from the vertical direction, it is possible to place a larger number of display portions 20 at one time.

[0025] In fact, when comparing the scanning work using the marker placement device 100 according to the first embodiment with the conventional scanning work in which each marker is attached and peeled off one by one, the working time using the marker placement device 100 according to this embodiment could be reduced to approximately 25% of the conventional working time (from about 20 minutes to about 5 minutes).

[0026] Furthermore, the support section 10 is not limited to just the first support section 11 and the second support section 12; it may consist of only the first support section 11, or it may have three or more support sections.

[0027] Furthermore, the support portion 10 shown in Figure 1 has a length L of 50 mm or more and 500 mm or less, and in the first embodiment, the length L is approximately 125 mm. Also, the display portion 20 has a diameter D of 5 mm or more and 100 mm or less, and in the first embodiment, the diameter D is approximately 10 mm.

[0028] In other words, in the marker installation device 100 according to the first embodiment, the length L of the support part 10 in the direction intersecting the vertical direction is 50 mm or more and 500 mm or less, and the display part 20 is circular in shape and has a diameter of 5 mm or more and 100 mm or less.

[0029] As a result, by setting the length L of the support part 10 to 50 mm or more and 1000 mm or less, the optimal display interval for the scanned object X can be achieved, and by setting the shape of the display part 20 to a circular shape and the diameter D to 5 mm or more and 500 mm or less, the display part 20 can be made to have optimal identifiability.

[0030] Figures 2(a) and 2(b) show the marker setting device 100 in its retracted state according to the first embodiment. Figure 2(a) is a schematic plan view of the marker setting device 100 in its retracted state, as seen from arrow A in Figure 2(b), and Figure 2(b) is a schematic front view of the marker setting device 100 in its retracted state.

[0031] As shown in Figures 2(a) and 2(b), in the marker setting device 100 according to the first embodiment, the first support part 11 and the second support part 12 overlap when viewed from the vertical direction when in storage.

[0032] This is possible because the second end 3 of the gripping portion 1 and the central portion of the first support portion 11, and the central portion of the first support portion 11 and the central portion of the second support portion 12 are rotatably mounted. In other words, the gripping portion 1, the first support portion 11, and the second support portion 12 are provided with a rotation mechanism (not shown), and each has the same axis of rotation along the vertical direction at the center of its respective central portion.

[0033] In other words, the support portion 10 of the marker setting device 100 according to the first embodiment has a rotation axis in the vertical direction at the center of the second end portion 3 of the gripping portion 1, and is rotatably mounted around the rotation axis.

[0034] As a result, the rotatable support section 10 makes it easy to adjust the position of the display section 20. Furthermore, if there are multiple support sections 10 (first support section 11 and second support section 12), they can be stacked vertically, making them compact when stored.

[0035] Furthermore, as shown in Figure 2, the display unit 20 is provided and fixed above the first display mounting portion 11a of the first support portion 11 and the second display mounting portion 12a of the second support portion 12. In this embodiment, the display unit 20 can be attached to and detached from the first display mounting portion 11a and the second display mounting portion 12a.

[0036] More specifically, the display unit 20 is made of a ferromagnetic material, and magnets (not shown) are provided inside the first display mounting section 11a and the second display mounting section 12a. In other words, the display unit 20 is fixed to the first display mounting section 11a and the second display mounting section 12a by the attractive force of the magnets, so that the display unit 20 can be easily replaced by a scanning device. Furthermore, in the first embodiment, the display unit 20 is provided on the upper side, but for example, a different display unit from the display unit 20 can be provided on the lower side, and the support section 10 can be used upside down as needed.

[0037] In other words, the display unit 20 of the marker setting device 100 according to the first embodiment is detachable from the support unit 10. By making the display unit 20 detachable from the support unit 10 and replaceable, it becomes easy to change the display unit 20 according to the scanning device and the object to be scanned X.

[0038] Furthermore, as described above, the marker installation device 100 according to the first embodiment is provided with magnets on the first end 2 and second end 3 of the gripping part 1, and on the first display installation part 11a and second display installation part 12a of the support part 10, and uses the attractive force of the magnets as the joining method.

[0039] In other words, the marker installation device 100 according to the first embodiment uses a joining method that utilizes magnetic attraction for at least the display unit 20, the first end 2, and a part of the second end 3. By using a joining method that utilizes magnetic attraction, the device can be repeatedly attached and detached, and the joining force during attachment and detachment can be easily adjusted.

[0040] Figure 3 is a schematic front view of the gripping portion 1. As shown in Figure 3, the gripping portion 1 has a first magnet 2a inside the first end 2, a second magnet 3a inside the second end 3, and a second needle portion 3b that protrudes from and can be retracted from the end.

[0041] As described above, in the first embodiment, since both the support portion 10 and the object to be scanned X are ferromagnetic materials, both the first end portion 2 and the second end portion 3 can be joined to the support portion 10 and the object to be scanned X.

[0042] In other words, when installing the marker installation device 100 on the object to be scanned X, if the second end 3 is joined to the support part 10 (as shown in Figure 1), the marker installation device 100 is installed by joining the first end 2 to the object to be scanned X. If the first end 2 is joined to the support part 10, the marker installation device 100 is installed by joining the second end 3 to the object to be scanned X.

[0043] Furthermore, for example, if the object to be scanned is made of a material such as polystyrene foam, the first end portion 2 is joined using magnetic attraction, so it cannot be joined to an object to be scanned that is made of polystyrene foam, which is not a magnetic material.

[0044] In contrast, since the second end portion 3 has a second needle portion 3b in addition to the second magnet 3a, the marker setting device 100 can be installed on the object to be scanned by piercing the second needle portion 3b into a non-magnetic material such as polystyrene foam and joining them together.

[0045] In other words, in the marker setting device 100 according to the first embodiment, both the first end 2 and the second end 3 of the gripping part 1 are detachable from the object to be scanned X and the support part 10, and when setting the marker setting device 100 on the object to be scanned X, there is a difference between a method in which the second end 3 is joined to the support part 10 and the first end 2 is set on the object to be scanned X, and a method in which the first end 2 is joined to the support part 10 and the second end 3 is set on the object to be scanned X.

[0046] As a result, the first end 2 and the second end 3 of the gripping part 1 are attached to the object X in different ways, making it possible to attach to various objects. Furthermore, the method of attachment to the object is not limited to magnets or needles; for example, adhesives such as double-sided tape, vacuum suction, etc., can also be used.

[0047] <Regarding the second embodiment> Next, the marker setting device 200 according to the second embodiment will be described with reference to the figures. Figure 4 is a schematic front view of the marker setting device 200 according to the second embodiment.

[0048] In the following description, only the differences from the first embodiment will be explained. In other words, the distinctive features that differ from the first embodiment will be described in detail, and the explanation of parts that have the same configuration as the first embodiment will be omitted.

[0049] As shown in Figure 4, the support portion 210 of the marker setting device 200 according to the second embodiment is curved. This is because the support portion 210 is made of a plastic material that can be deformed by external force such as manual force and maintains its shape after deformation. Examples of the plastic material for this support portion 210 include a flexible curve ruler (a ruler with lead embedded in it), a coated copper or other metal wire, etc.

[0050] As a result, even with curved scanning objects Y as shown in Figure 4, the support portion 210 can plastically deform to conform to the curve of the scanning object Y, and the display portion 20 can accurately read positional information for curved scanning objects Y into the scanning device.

[0051] In other words, the support portion 210 of the marker placement device 200 according to the second embodiment is made of a plastic material that maintains its deformed shape after being deformed by an external force. As a result, the support portion 210 can be shaped to conform to the shape of the object Y to be scanned, thereby providing more accurate positional information.

[0052] Furthermore, as shown in Figure 4, the marker setting device 200 according to the second embodiment is provided with auxiliary parts 30 that are in contact with the support part 210 and the object to be scanned Y, between both ends of the support part 210 and the object to be scanned Y.

[0053] The auxiliary part 30 has a height H at the distance from one end to the other, which is the same height H as the distance from one end to the other of the gripping part 1. In the second embodiment, the auxiliary part 30 is provided with magnets on the support part 210 and on the part that comes into contact with the object to be scanned Y, and is fixed by the attractive force of these magnets. Therefore, in the three display units 20 shown in Figure 4, the distance from the object to be scanned Y is kept constant, so the display units 20 can provide more accurate positional information of the object to be scanned Y.

[0054] In other words, the marker setting device 200 according to the second embodiment has an auxiliary unit 30 that is positioned between the support unit 210 and the object to be scanned Y, and that contacts both of them, thereby keeping the distance between the display unit 20 and the object to be scanned Y constant.

[0055] This allows the auxiliary unit 30 to maintain a constant distance between the object Y being scanned and the display unit 20, thereby providing even more precise positional information. Furthermore, when using the auxiliary unit 30, the support unit 210 does not necessarily need to be made of a plastic material; it can be made of an elastic material as long as it can be fixed by the auxiliary unit 30.

[0056] <Regarding the third embodiment> Next, the marker setting device 300 according to the third embodiment will be described with reference to the figures. Figures 5(a) and 5(b) are schematic front views of the marker setting device 300 according to the third embodiment, where Figure 5(a) shows the support portion 310 in a shortened state, and Figure 5(b) shows the support portion 310 in a lengthened state.

[0057] As shown in Figures 5(a) and 5(b), the marker setting device 300 according to the third embodiment is equipped with an expandable / contractible mechanism 311. The expandable / contractible mechanism 311 is a cylindrical member that extends along the support portion 310, into which the support portion 310 is inserted from both sides of the inside of the cylinder.

[0058] To position the display unit 20 on the inside, insert the outer support part 310 all the way into the telescopic mechanism 311 (to the inside), as shown in Figure 5(a). Conversely, to position the display unit 20 on the outside, insert the outer support part 310 all the way to the front of the telescopic mechanism 311 (to the outside), as shown in Figure 5(b).

[0059] In other words, the support portion 310 of the marker installation device 300 according to the third embodiment is equipped with an extendable mechanism 311 that allows adjustment of the length in a direction intersecting the vertical direction. As a result, the position of the display unit 20 can be easily adjusted by adjusting the length of the support portion 310.

[0060] Furthermore, the telescopic mechanism 311 for extending and retracting the support portion 310 is not limited to the structure shown in Figure 5. For example, the support portion may be divided into two parts and superimposed, and the length of the superimposed parts may be adjusted to extend or retract the support portion.

[0061] <Regarding the fourth embodiment> Next, the marker setting device 400 according to the fourth embodiment will be described with reference to the figures. Figure 6 shows the state of the marker setting device 400 according to the fourth embodiment when it is housed.

[0062] As shown in Figure 6, the marker setting device 400 according to the fourth embodiment has a hinge 411 on the outer circumference of the central portion 412 of the support portion 410 that rotatably connects the central portion 412 and the support portion 410.

[0063] The axis of rotation of the hinge 411 is aligned in a direction intersecting the vertical direction, and in the fourth embodiment, since the central portion 412 is circular, it is aligned in the tangential direction of the central portion 412. In Figure 6, the axis of rotation of the hinge 411 is aligned in a direction that penetrates the plane of the paper.

[0064] In Figure 6, the support portion 410 is shown in its retracted state. When the hinge 411 is opened to open the support portion 410 like an umbrella, a stopper portion (not shown) is provided on the hinge 411 that stops the support portion 410 in a direction that intersects vertically.

[0065] Therefore, when the support portion 410 is rotated in the opening direction from the state shown in Figure 6, the support portion 410 stops in an extended state intersecting the vertical direction, and the display portions 20 at both ends are positioned in predetermined locations.

[0066] In other words, the support portion 410 of the marker setting device 400 according to the fourth embodiment has a rotation axis on the outer circumference of the central portion 412 of the support portion 410, aligned in a direction intersecting the vertical direction, and is rotatably mounted around the rotation axis. As a result, the support portion 410 can be folded like an umbrella, making it compact for storage.

[0067] <Regarding other embodiments> The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.
