Description

Apparatus for supporting correct attachment of marker}

The present invention relates to a device that supports precise attachment of a marker.

A variety of complex structures and equipment are installed on ships and marine plants.

And, as illustrated in Figure 1, the corresponding 3D model images, design drawings, etc. can be viewed by workers in a specific area using augmented reality techniques using smart devices and used for purposes such as work instructions and quality verification. A plate-shaped marker 100 with a marker on it is installed on the floor or wall of the area (see Figure 1).

At this time, as illustrated in (b) of FIG. 1, in order to precisely match the real block and the 3D model, the landmark 100, which serves as the standard, needs to be attached precisely.

However, in reality, because the marker 100 is attached depending on the operator's feeling, it cannot be attached precisely along the reference line as illustrated in (a) of Figure 2, and as shown in (b) and (c) of Figure 2. As illustrated, it may be attached away from the reference line, or may be attached in a rotated state.

If the marker 100 is attached horizontally spaced apart from the reference line in the x, y, or z axis direction, the real block and the 3D model can be aligned by applying a constant value to correct, but if it is attached by rotating on the xyz three-dimensional plane, There is a problem in that the error tends to increase in proportion to the distance, making precise matching difficult.

Referring to FIG. 3, the support device 300 that supports precise attachment of a marker may include a first body unit 301, a second body unit 302, and a connecting means 303.

The connecting means 303 is installed to connect opposing first sides of the first body unit 301 and the second body unit 302 to each other.

For example, the connecting means 303 may have a telescopic structure, that is, a plurality of powders may be provided in multiple stages so that the length can be adjusted in the first direction (for example, the X-axis direction). Accordingly, the separation distance between the first body unit 301 and the second body unit 302 may vary depending on the length adjustment of the connecting means 303.

The first body unit 301 and the second body unit 302 each include a main body (311, 312), attachment means (321, 322), gap adjustment means (331, 332), and reference line housings (341, 342). It can be included.

Opposite first sides of the main bodies 311 and 312 of the first body unit 301 and the second body unit 302, respectively, are connected to each other by a connecting means 303.

Attachment means 321 and 322 are mounted on the upper sides of the main bodies 311 and 312. The attachment means 321 and 322 are attached to the target surface to maintain the position of the main bodies 311 and 312, and may be various, for example, magnet members, adsorption members, etc.

Spacing adjustment means (331, 332) are coupled to the second side of the main body (311, 312), and reference string housings (341, 342) are coupled to the ends of the spacing adjusting means (331, 332).

The gap between the reference line housings 341 and 342 and the main bodies 311 and 312 can be adjusted by the gap adjustment means 331 and 332. For this purpose, the spacing adjustment means (331, 332) is, for example, relative to the main bodies (311, 312) in a direction that is drawn out of the main bodies (311, 312) or in a direction that is received inside the main bodies (311, 312). It can be combined with the main body (311, 312) so that it can be moved. As another example, the spacing adjustment means 331 and 332 may be implemented as a telescopic structure.

In order to maintain the gap between the main body (311, 312) and the reference line housing (341, 342) adjusted by the spacing adjusting means (331, 332), the adjustment state of the spacing adjusting means (331, 332) is fixed by the fixing pin. It can also be fixed using, etc.

In addition, in order to easily recognize the adjusted gap between the main body (311, 312) and the reference line housing (341, 342), a scale is formed on the surface of the gap adjusting means (331, 332). , a tape measure may be provided in the spacing adjustment means (331, 332).

Guide holes through which the reference string 350 is drawn out are formed in the reference string housings 341 and 342. Inside the reference line housings (341, 342), a spool is installed that rotates about the rotation axis to wind the reference line 350. In order to maintain elasticity in the direction in which the reference line 350 is always wound, the reference line housing ( 341, 342) and a spring with both ends fixed to the spool may be installed.

The reference line 350 may be wound and fixed to the spools of the reference line housings 341 and 342 of the first body unit 301 and the second body unit 302, respectively.

As illustrated in FIG. 3, reference line housings 341 and 342 may be provided in both the first body unit 301 and the second body unit 302, respectively, but as illustrated in FIG. 4, the reference line housings (341, 342) may be provided in only one of the first main body unit 301 and the second main body unit 302.

That is, the reference line housings 341 and 342 are provided only in one of the first body unit 301 and the second body unit 302, and the other of the first body unit 301 and the second body unit 302 One may be provided with a fixing means 410 for fixing the end of the reference line 350 pulled out from the reference line housings 341 and 342.

As described above, the first body unit 301 and the second body unit 302 are connected using the connecting means 303 installed to connect the opposing first sides of the first body unit 301 and the second body unit 302 to each other. When the separation distance between the main body units 302 is adjusted, the spools inside the reference line housings 341 and 342 are rotated to pull out the reference line 350 to a corresponding length.

Figure 5 illustrates the use of the support device 300. As illustrated in FIG. 5 , it is assumed that there is a weld seam 510 recognized as a reference line for attaching the marker 100 to the second surface.

In order to enable the marker 100 to be precisely attached based on the weld seam 510, attachment means 321 and 322 provided in the first body unit 301 and the second body unit 302, respectively, are used. Each is attached to the first adjacent side so that it is perpendicular to the two sides. At this time, the distance between the first body unit 301 and the second body unit 302 can be adjusted using the connecting means 303, and the distance between the first body unit 301 and the second body unit 302 can be adjusted. The exposed length of the reference line 350 will also be adjusted corresponding to the adjusted spacing.

In addition, the spacing adjustment means (331, 332) is adjusted to adjust the gap between the reference line housings (341, 342) and the main body (311, 312) so that the reference line (350) is appropriately positioned to correspond to a predetermined reference line. can do. The worker can attach the marker 100 to the second side by referring to the posture of the reference line 350.

Here, the reference line may be, for example, the center of the weld seam 510 or may be designated as a specific corner.

However, in the field, it is difficult to set an accurate reference line because the weld seam 510 generally does not have a straight shape and its thickness is not constant. In addition, it is difficult to recognize how far away the marker 100 is from the set reference line and whether it is attached at an exact angle.

However, the support device 300 according to this embodiment is attached using attachment means 321 and 322, and the position of the reference line 350 is adjusted by adjusting the connection means 303 and the gap adjustment means 331 and 332. Since it is fixed, there is an advantage in that it is possible to accurately recognize the distance and angle at which the marker 100 is attached from the set reference line.

In addition, since the attachment position and angle of the marker 100 can be accurately recognized, the corresponding information can be accurately displayed, and this has the advantage of allowing design data such as real blocks and 3D model images to be accurately matched in the field.

Therefore, augmented reality technology can be effectively utilized using the marker 100 attached to the field. For example, before equipment such as piping or cables is installed, work instructions regarding the installation shape or location can be given using the 3D model augmented reality technique using the attached marker 100. In addition, even after the equipment is installed, installation accuracy can be evaluated using 3D model augmented reality techniques.
