Description

Wood data collection device

[0001] The present invention relates to a wood data collection device, and more particularly, to a wood data collection device capable of accurately measuring the entire shape of wood, such as curved timber, in three dimensions by scanning the entire shape of wood while a scanner rotates with respect to the wood along with sliding movement of a scan module with respect to a moving guide.

[0002] Generally, buildings or structures using wood are made by processing cylindrical wood into tubes or rods, and in places where aesthetic appeal is required, cylindrical wood is used as is to express the original shape of the wood.

[0003] When using wood as is, it is important to determine the degree of warpage of the wood. In the past, the shape of the wood was roughly determined by eye and then the wood was applied as needed. However, in this case, because the shape of the wood was not measured using an accurate measurement method, there were limitations in accurate application.

[0004] Meanwhile, a method that can scan the outer surface of wood and extract the shape of the wood based on the scanned information can be applied, but in the past, although there were devices that could extract shape information for various objects as well as wood, there was a lack of development of scanning devices specialized for wood, so there were limitations in determining the exact shape of wood.

[0005] Accordingly, there is a need to develop a new wood data collection device capable of accurately measuring the external shape of wood using a simple method.

[0006] Related prior art includes Korean Patent Registration No. 10-2507876 (Title of invention: 3D scanner platform and 3D scanning device equipped therewith).

[0007] An embodiment of the present invention provides a wood data collection device capable of accurately measuring the shape of wood, such as curved timber, in three dimensions by scanning the overall shape of the wood while the scanner rotates with respect to the wood along with sliding movement of the scan module with respect to the moving guide.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

[0024]

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0026] FIG. 1 is a perspective view showing the entire configuration of a wood data collection device according to one embodiment of the present invention, FIG. 2 is a perspective view showing the configuration of fixed members provided at both ends of the base portion of FIG. 1, FIG. 3 is a perspective view showing the scan module shown in FIG. 1, FIG. 4 is a drawing for explaining the movement principle by the pinion gear of the moving member shown in FIG. 3 and the rack gear provided in the moving guide, and FIG. 5 is a drawing for explaining the laser marking member provided on the other surface of the mounting plate shown in FIG. 3.

[0027] As shown in these drawings, a wood data collection device (100) according to one embodiment of the present invention may include a base (110) having a fixing member (130) for fixing both ends of wood (101) and a moving guide (111), a scan module (150) that scans the surface of wood (101) while sliding along the moving guide (111), and a data processing unit (180) that processes, merges, and stores data on the surface of wood (101) scanned by the scan module (150).

[0028] By this configuration, it is possible to collect data on the overall shape of the wood (101) by scanning the entire area of ​​the wood (101), such as a curved piece, for example.

[0029] When explaining each configuration, first, the base part (110) of the present embodiment is provided as a frame having an overall rectangular shape, as illustrated in FIGS. 1 and 2, and fixing members (130) for fixing both ends of the wood (101) may be respectively arranged. In addition, a pair of moving guides (111) may be provided and arranged parallel to each other on both sides along the longitudinal direction of the wood (101).

[0030] Through this configuration, after fixing both ends of the wood (101) to a pair of mutually spaced fixing members (130), scanning of the overall shape of the wood (101) can be performed by moving the scan module (150) along the moving guide (111).

[0031] The fixing members (130) of the present embodiment may be provided in pairs and arranged symmetrically on both sides of the base portion (110), as shown in FIGS. 1 and 2.

[0032] Such a fixing member (130) may include, as illustrated in FIG. 2, a fixing body (131), a plurality of disconnected parts (137) that are mutually linked to each other so that the ends of the wood (101) can be deformed according to a curved shape, a wood fixing part (136) that supports the wood (101), and a connecting chain (135) that connects both ends of the wood fixing part (136) to a length-adjusting winding part (133) provided at the upper end of the fixing body (131) so that the wood fixing part (136) that fixes the wood (101) becomes U-shaped.

[0033] The fixed body (131) of the present embodiment may be equipped with a moving wheel (132) at the lower end, as illustrated in FIG. 1, and thus may be moved along the longitudinal direction in which the moving guide (111) is formed. However, a guide member (115) may be provided on the moving path of the moving wheel (132) so that the fixed body (131) can be moved in a straight line along the longitudinal direction of the moving guide (111).

[0034] The guide member (135) not only allows the fixed body (131) to move linearly along the length direction of the moving guide (111) as shown in Fig. 1, but also prevents the fixed member (130) of the present embodiment from colliding with the scan module (150) by limiting the degree of movement.

[0035] The fixed body (131) of this embodiment has a structure that stands upright as a whole, but as shown in FIG. 2, a hole (131h) is provided that penetrates from just below the upper part to the central part, so that the end of the wood (101) can be placed by penetrating through the hole (131h).

[0036] A length-adjusting winding part (133) for rolling or unrolling a connecting chain (135) may be provided at the upper end of the fixed body (131). The length-adjusting winding part (133) has a structure that is symmetrical on both sides, and a connecting chain (135) may be provided at each part for rolling or unrolling.

[0037] Referring to Fig. 2, a rotation motor (134) that generates a rotational force to simultaneously wind or unwind the connecting chains (135) on both sides may be provided at the center of the length-adjusting winding portion (133), thereby allowing the connecting chains (135) arranged on both sides to be lowered or wound by the same length at a time.

[0038] At the ends of the connecting chains (135) that are lowered in parallel to each other, both ends of the wooden fixing part (136) can be connected, as shown in FIG. 2. Since the plurality of disconnected parts (137) that constitute the wooden fixing part (136) are linked to each other, the interconnected disconnected parts (137) can rotate with respect to one disconnected part (137), and therefore, as shown in FIG. 2, the wooden fixing parts (136) connected to the connecting chains (135) that are lowered in parallel to each other can have an overall swing shape, i.e., a U shape.

[0039] By this configuration, when the wood (101) is placed on the wood fixing part (136), the cut parts (137) of the wood fixing part (136) of the wood (101) can be mutually positioned according to the shape of the wood (101) to firmly support the wood (101), and the connecting chain (135) wound around the length-adjusting winding part (133) can be appropriately rolled or unrolled to firmly fix the end of the wood (101) to the wood fixing part (136) at a desired position.

[0040] However, in this embodiment, the wood fixing part (136) is formed by linking multiple disconnected parts (137), but it is not limited thereto, and it is obvious that other structures can be applied as long as they can firmly support the wood (101).

[0041] Meanwhile, the movement guide (111) of the present embodiment provides a movement path of the scan module (150), which will be further explained when describing the scan module (150).

[0042] The scan module (150) of the present embodiment may include a sliding moving part (160) that moves along a moving guide (111), as shown in FIGS. 1 and 3, and a scanner rotation part (170) that is mounted on the sliding moving part (160) and has a scanner (175) for scanning wood (101) and rotates the scanner around the wood (101) to obtain information on the surface of the wood (101).

[0043] As described above, the moving guides (111) of the present embodiment are provided in pairs along the longitudinal direction on both sides of the wood (101), and the sliding moving part (160) of the present embodiment may also include a pair of moving members (161) for moving along the pair of moving guides (111), and a connecting member (165) for connecting the pair of moving members (161).

[0044] And, a scanner rotation part (170) is mounted on the connecting member, and the scanner rotation part (170) equipped with a scanner (175) can be mounted so that one part can rotate relative to another part.

[0045] Referring to FIGS. 3 and 4, a rack gear (112) may be provided along the longitudinal direction of the moving guide (111), and a pinion gear (162) that engages with the rack gear (112) may be provided at the lower end of the moving member (161).

[0046] In addition, a rotation motor (163) and a reducer (164) may be mounted on the shaft of the pinion gear (162) of the moving member (161), so that when the rotation motor (163) rotates, the reducer (164) rotates, and the pinion gear (162) rotates to slide linearly with respect to the rack gear (112) of the moving guide (111), and thereby the entire scan module (150) including the moving member (161) can be linearly moved along the longitudinal direction of the moving guide (111).

[0047] In this way, in the case of the present embodiment, the pinion gear (162) of the moving member (161) has a structure in which it slides relative to the rack gear (112) of the moving guide (111), so that the entire scan module (150) can be moved precisely without vibration, and through this, scanning work can be accurately performed on the entire area of ​​the wood (101).

[0048] Meanwhile, referring to FIG. 3, a roller (166) that rotates along a moving guide (111) is provided at the lower end of the moving member (161), and similarly, a roller (167) that rotates along the longitudinal direction of an upper frame (113) forming a frame of a base part (110) is provided at the upper end (167) of the moving member (161), and the scan module (150) can smoothly move along a moving path formed by the base part (110) through these rollers (166, 167).

[0049] The scanner rotation unit (170) of the present embodiment may include, as shown in FIGS. 1 and 3, a mounting plate (171) that is mounted on a rectangular frame formed by a movable member (161) and a connecting member (165) and has a hole (171h) through which wood (101) can pass, a drive rotation member (173) that is mounted so as to be rotatable in place at the upper end of the mounting plate (171), and a driven rotation member (176) that is provided on one side of the mounting plate (171) and has a through hole formed through which wood (101) can pass, and on which a scanner (175) is mounted on the inner surface, and that rotates when the drive rotation member (173) rotates.

[0050] Here, the driven rotation member (176) also has a structure that rotates in place, and although not shown in detail, a structure that guides the rotation of the driven rotation member (176) while preventing it from coming off is provided on one side of the mounting plate on which the driven rotation member (176) is mounted, so that when the driving rotation member (173) rotates, the driven rotation member (176) can also rotate accurately in place.

[0051] Referring to FIG. 3, a driving gear (174) may be provided along the circumference of a driving rotary member (173), and a driven gear (177) that engages with the driving gear (174) of the driving rotary member (173) may be provided along the circumference of a driven rotary member (176).

[0052] Accordingly, when the shaft of the rotary motor (178) coupled to the driving rotary member (173) rotates, the reducer (172) connected to the rotary motor (178) operates to rotate the driving rotary member (173), and the driven rotary member (176) can be rotated by the rotation of the driving rotary member (173). In addition, the scanner (175) can scan multiple areas of the wood (101) by rotating around the wood (101) by the rotation of the driven rotary member (176).

[0053] In other words, since the entire scan module (150) moves linearly along the moving guide (111) by the sliding moving part (160) and at the same time the scanner (175) rotates around the wood (101) by the operation of the scanner rotating part (170), the scanner (175) can collect formation data for multiple areas of the wood (101) while moving in a spiral direction with respect to the wood (101).

[0054] In addition, a total of four laser marking members (179) can be mounted at 90-degree intervals on the opposite side of the surface on which the driving rotary member (173) is mounted on the mounting plate (171). A total of four laser marking members (179) can create four straight lines on the surface of the wood (101) to provide a guide for work and assembly.

[0055] Meanwhile, data of wood (101) scanned by the scanner (175) can be processed in the data processing unit (180). The data processing unit (180) of the present embodiment can process, merge, and store data on the surface of wood (101) scanned by the scanner (175).

[0056] In detail, the scan module (150) slides along the moving guide (111) and moves from one end of the wood (101) to the other end, scanning the surface of the wood (101) by the scanner (175). At this time, the scanner (175) rotates around the wood (101) by the rotation structure of the scanner rotation unit (170), and can scan, for example, four areas at 90-degree intervals on the same cross-section, and since this scanning operation is performed continuously, scan data for the entire area of ​​the wood (101) can be acquired.

[0057] And, the data processing unit (180) can perform data processing based on the acquired scan data, which can be performed through the following steps.

[0058] First, the scan data can be imaged through data processing in the data processing unit (180). That is, an image can be created using the scan data. Next, the data processing unit (180) can calculate geometric information and weight using a vectorization technique. Geometric information and weight, such as the maximum length, maximum diameter, and minimum diameter of the wood (101), can be calculated.

[0059] Next, the vectorized data by the data processing unit (180) can be viewed using the viewer. The viewer can enlarge, reduce, or rotate the image, and the user can view it. Next, structures can be placed and configured on the web. In other words, data can be combined on the web to place and configure structures.

[0060] In addition, after confirming the vectorized data by the data processing unit (180), the data can be downloaded to the user's computer. The downloaded data can be an image or a CAD, DXF, or STEP format file. The data can then be combined on the user's computer and placed and configured within the user's structure.

[0061] In this way, according to the present embodiment, the entire shape of the wood (101) can be accurately measured in three dimensions by scanning the entire shape of the wood (101) while the scanner (175) rotates with respect to the wood (101) along with the sliding movement of the scan module (150) with respect to the moving guide (111).

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the claims set forth below, but also by equivalents thereof.

[0064] Although the present invention has been described with reference to limited embodiments and drawings, it is not limited to the above-described embodiments. Those skilled in the art will appreciate that various modifications and variations are possible based on this disclosure. Therefore, the scope of the present invention should be understood solely by the scope of the claims set forth below, and all equivalent or equivalent modifications thereof are deemed to fall within the scope of the present invention.
