Description

The present invention relates to a marking line drawing work method using an MR (mixed reality) field of view in a construction space.

In the conventional marking line drawing work, multiple reference points are set, and based on the reference lines connecting them, dimensions are measured and angled using a convex, a tape measure, and a right angle ruler, and water threads, chokes, and marking pens are used. The work of drawing the actual size of the drawing drawing on the floor with parallel lines and right-angled lines was performed in order from the reference line side.

However, there is a problem that it is almost impossible for an amateur to draw a marking line on the floor because it requires a so-called "craftsmanship" by skill to perform the marking line drawing work as in the past. ..

Marking line drawing work There are various problems described below in performing the marking line drawing work as in the past. There were various problems.

That is, based on the reference line connecting the two reference points, it is necessary to measure and draw a parallel line close to the reference line and a right-angled line intersecting the reference line according to the dimensions shown in the drawing drawing. It takes time to draw a line for a space far from the distance, it is extremely difficult to draw a line for a space away from the reference line, ignoring the order of drawing, and it requires so-called "craftsmanship" by skill, so it is an amateur. There was a problem that it was almost impossible to draw a line on the floor.

On the other hand, when multiple reference lines are set and drawn, the parallel lines and right-angled lines drawn based on each reference line have slightly different vertical and horizontal dimensions, such as expansion and contraction of the measure used. If there is an error in the final line from both reference lines, it is necessary to repeat the line drawing work, and as in the previous term, so-called "craftsmanship" by skill is required, so it is very difficult for an amateur to construct. There was a problem.

As mentioned above, it is extremely difficult not only for amateurs but also for experienced line drawing work because it requires a very high level of skill to shorten the time required for marking line drawing work and to construct the floor surface in a space away from the reference line. Therefore, there is a problem that a large amount of time is required for the work.

In recent years, with the development of technology, various advanced systems such as MR (Mixed Reality) have appeared, and the skilled population has tended to decrease as the social structure changes. This is no exception to the workers who perform such activities, and in the exhibition industry, it is an important issue to deal with the shortage of construction workers.

In addition, when the marking work is carried out in MR mixed reality, the dimensional tolerance cannot be guaranteed and verified in a large space such as an exhibition hall, and the auxiliary use of the conventional drawing work is the limit. At the same time, it takes time to store data in equipment for spatial recognition during use, and it takes about the same amount of time as conventional work to learn the entire exhibition hall, and the introduction of MR technology is progressing. did not exist.

The present invention has been made in view of the above circumstances, and by making it possible to perform the marking line drawing work without requiring skill, it is possible to contribute to the shortage of skilled workers such as construction workers, and further, the water drawing line drawing. MR (Mixed Reality) has made it possible to improve work efficiency, reduce construction costs, and shorten the construction period by making it possible to perform marking construction quickly and in line with the construction schedule for each space. The purpose is to provide a method of drawing lines with black ink.

In the present invention, in order to achieve the above object, a reference point for recognizing the correlation position of MR (mixed reality) is set at an arbitrary position in the construction space, and the line drawing is displayed in the MR (mixed reality) field of view. In order to maintain the dimensional accuracy of the line, by correcting the error of the correlation position of the reference point installed when switching the reference point, it is possible to draw the marking line on the entire exhibition hall and event hall, and to the specified position. In addition to providing the marking work method using MR (Mixed Reality), which is characterized by being able to perform the marking work of the required part by omitting the drawing work of, the space recognition necessary for the use of MR equipment is provided. The above-mentioned problem is achieved by holding the space recognition data for each venue in advance for the learning time of the device for the purpose.

According to the present invention, the work that required 12 to 16 people per venue in the conventional marking line drawing work method can be performed by 4 to 5 people, and for space recognition for using MR. It is possible to reduce the number of non-working hours and the required number of workers, and to draw lines and mark out multiple sections according to the priority of the setup process, which has the effect of significantly reducing the number of personnel and time.

Conventionally, when setting the reference line before the marking work, the reference line is measured using a convex and a tape measure, and the reference line is visualized using water thread, and the division distance in the exhibition hall and the event hall is long. , It took about 40 minutes to set, but by using the marking line drawing work method using MR (Mixed Reality) of the present invention, if one base point is recognized, the marking line drawing work can be proceeded immediately. This saves a lot of time.

If the distance of the conventional reference line is longer than that of the existing measure, it is necessary to provide the reference line again, which requires more work time, but the time is also shortened.

Since the exhibition hall facilities used are used many times, the work of determining the reference point can be shortened by fixing the starting point for each venue.

There are many exhibition venues, not only square venues, but also circular and triangular venues that are difficult to draw, and it was necessary to remeasure the places that did not fit in the section each time, but by using AR / VR, the image Therefore, the measurement time is shortened.

In sections with obstacles such as venue pillars, re-tensioning of majors and water threads and movement of personnel occur, but in mixed reality, that work does not occur, so time can be shortened.

In planning the construction schedule, it was necessary to adjust the work order back and forth due to the convenience of carrying-in work and underfloor work, but by using MR (Mixed Reality), marking lines are drawn according to the overall work. Since work planning can be done, construction can proceed without delaying other work.

In the work of drawing a line on the outer circumference from the wall of the venue, which does not fit in the standard section, the work of setting a new standard and drawing the line is required, but since the marking can be done without setting a standard, the time and the number of workers can be reduced. ..

By implementing and providing the space recognition required for the use of MR equipment in advance for each venue, the time until the start of using MR equipment can be significantly shortened.

Conventionally, measuring equipment such as a tape measure or a tape measure is used to set the reference line before the marking line drawing work, but the tension of the measuring equipment at the time of measurement, individual differences in the equipment itself, and the equipment Factors such as material elongation due to deterioration and temperature can be completely eliminated, and accurate and stable measurement can always be performed.

It is a sample drawing of the drawing drawing used for the drawing work. It is a mixed reality field of view that can be seen when a mixed reality machine is attached. It is the figure which attached the mixed reality machine and looked at the marking point appearing in the mixed reality field of view from directly above. It is explanatory drawing which sets the reference point for every area of 30m × 30m in order to maintain the dimensional accuracy of mixed reality. It is a figure which attaches the mixed reality machine and confirms the range which guarantees the dimensional accuracy with reference point 1 as a base point.

Hereinafter, an example of the marking line drawing work method using MR (Mixed Reality) according to the present invention will be described in detail with reference to the drawings.

Constitution

In the drawing work in the construction space such as the exhibition hall and the event venue, the dimensional accuracy of the MR (mixed reality) field is ensured in the MR (mixed reality) view views 2 and 3 without checking the line drawing drawing Fig. 1 each time. Therefore, in the environment diagram 4 in which the reference points are arranged at intervals of 30 m, the drawing is imported for each reference point set in advance according to the progress of the drawing work, and the dimensional error with the already drawn points is corrected by switching. This enables a wide range of delineation and marking work, and marks the intersections necessary for zoning, which are displayed in the mixed reality field FIGS. 2 and 3, according to the work priority order after the fact.

In implementing the marking line drawing work method using MR (Mixed Reality), the target space for drawing and marking is recognized in advance, and an arbitrary point on the floor (corner pit, etc. in the case of an exhibition hall) is used as a reference point. Create a drawing diagram set to 1 and transfer the electronic medium data of the drawing diagram to the MR (Mixed Reality) machine (Microsoft HoloLens) under the wireless environment by performing visible conversion to MR (Mixed Reality), which is an existing technology. do.

The drawing operator can set the reference point 1 (Fig. 5) set above on the floor surface to be marked and drawn, and attach the Microsoft HelloLens to which the drawing drawing is visualized and transferred, in a state where the space is recognized in advance. The reference point 2 that satisfies the dimensional tolerance and is displayed is recognized, marked, and the position is specified.

The farthest point of the area that can be drawn by the reference point 1 (FIG. 5) after the position is specified is set as the reference point 2 (FIG. 6), marked according to the display of MR (mixed reality), recognized as the reference point, and the reference point. The reference point 1 is confirmed from the point 2 (FIG. 6), and the dimensional error in the position designation is corrected.

The most effective position for drawing parallel and vertical marking lines from the reference point 1 (Fig. 5) and the reference point 2 within the area where the line can be drawn within the allowable dimensional tolerance by specifying the reference point of the reference point 2 (Fig. 6). In the case of this embodiment, the reference point 3 (FIG. 7) is an extension of the reference point 2 (FIG. 6) in which squares whose diagonal lines are the reference point 2 (FIG. 6) are arranged from the reference point 1 (FIG. 5). ) Is marked according to the display of MR (composite reality), recognized as a reference point, the reference point 1 and the reference point 2 are confirmed from the reference point 3 (FIG. 7), and the dimensional error is corrected by specifying the position.

By the above-mentioned work, the reference point 1 (FIG. 5) is switched to the reference point 2 (FIG. 6), and the reference point 2 (FIG. 6) is switched to the reference point 3 (FIG. 7). In FIG. 5), it is possible to draw a line within the allowable tolerance for a region 6 times the drawable region.

Conventionally, two lines perpendicular to the reference point 1 (FIG. 5) are materialized using water threads from the point positioned after measurement, and while checking the drawing diagram from the region close to the reference point 1 (FIG. 5), By repeating measuring, scoring, and drawing water threads, the work of marking the intersections of all the water threads was performed, and it was not possible to deal with the time-series priority of drawing lines and marking out.

In the case of the embodiment, it was necessary to specify 36 points by measuring and draw 18 parallel and vertical lines with water thread, but by the method of drawing the marking line using MR (Mixed Reality), 2 It was possible to draw a line and mark out the target position only by marking the reference point at the location and correcting the error by switching the reference point.

According to the present invention, exhibition booth division, booth division, and more specifically, two-dimensional correlation positions of crops in individual spaces at exhibitions and events are specified by taking new means to draw lines and divide them. The work can be carried out quickly, easily, and according to the priority, the work efficiency can be improved, the construction period can be shortened and the construction cost can be reduced, and the construction can be performed without the need for skill. It can also contribute to solving the problem of worker shortage.
