[0002]

2. Description of the Related Art In most cases, a room on which a tatami mat is placed is not curved but is distorted. For this reason, before putting the tatami, measure the shape of the room, the tatami on the side that hits the wall must be shaped according to that part, unless you can put the tatami into the room, you must measure the dimensions of the room No. Conventionally, in order to measure this dimension, a yarn is pulled in a cross shape into a room, the two yarns intersect at 90 °, and the distance from the yarn to each side of the room is measured with an object. In recent years, instead of a thread, a device that emits a cross-shaped visible ray has been installed at about the center of a room, and the distance from the ray to each side of the room has been measured by pointing. The device that emits light is easier to measure than a yarn, and the measurement time is shorter.

Particularly in recent years, many large apartment buildings have been constructed, and it is often necessary to measure 50 rooms or more in one day, which requires more labor and time than conventional equipment. , Price 3
Currently, it is not widely used because it has more than doubled.
In recent years, in apartment houses, concrete pillars called “notches” are often present in the corners of the room or in the middle of the walls, and these notches are not measured by an automatic measuring device but are measured by pointing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, there is illustrated an overall configuration of a measuring device (measuring machine) 1 according to the present invention. As an example of a means for measuring a linear distance without contact, a distance meter (distance measuring means) 2 using a laser beam (visible laser beam) and a rotary encoder 3 for measuring an angle are rotatably measured on a machine base 4. Provided in part 5,
It is a device that measures distance and angle at the same time.

The distance meter 2 emits a laser beam as a pulse, and measures the time of reflection and return by a signal processing system. The laser light of this distance meter 2 is
The pinion gear 6 is mounted on the shaft 3A of the rotary encoder 3 with respect to the angle, and the fixed gear 7 is mounted on the machine base 4 so as to increase the speed by, for example, 20 times.
And a method of detecting 50,000 pulses is adopted. Note that 50,000 pulses are arbitrary. The mechanical structure is such that an adjusting foot 8 composed of, for example, three screw rods is attached downward to a lower frame (machine base) 4 so that the machine can be leveled. The outer periphery of the lower frame 4 is provided with 0.5 modules × 240 gears 7. The shaft 10 supported by the bearing 9 at the center of the lower frame 4
It protrudes vertically upward. This shaft 10 has a gantry 11
An operation panel 11 for operating keys on the upper part of the gantry, a laser distance meter 2 for measuring a linear distance, and an encoder 3 for detecting an angle are fixed, and a deflection for refracting a laser beam. A body 12 is provided extending downward.

When a laser beam is applied to the center of the corner of a room, the laser spot hits two different surfaces and accurate distance measurement cannot be performed. Therefore, it is necessary to correct this and improve the accuracy of length measurement. As this means (method), a method of correcting an error by collecting field data or the following method is used. The thickness of the laser beam increases as the distance increases, and is proportional to the distance. The thickness of the laser beam and the angle of spread of the beam are as shown in FIG. In FIG. 4, the diameter of the spot light of the laser beam is 2 mm away from 2000 mm.
m, if it is 10,000 mm apart, it will be 10 mm. Therefore, the diffusion angle of light is

[0018]

(Equation 1)

Since the length measured by the laser beam is the strongest part of the reflected light, if the center of the spot light source is considered, the correction for the corner of the room is shown in FIG. As follows. In FIG. 5, if the left side of the spot light hits the corner of the sill of the room, the shape of the hit light becomes an ellipse Q as shown in FIG. Accordingly, the center point of the spot light, from the corner 1 A point room 0.
The point B is 02865 ° apart. The measuring unit 5 in the measuring device 1 shown in FIGS. 1 and 2 is manually rotated about the vertical axis 10 to measure 2 , 3 , and 4 in order. The center of the spot light is applied to the point to be measured at each point except for the corners of the room, and the distance is measured by the measuring means 2 and the angle is measured by the encoder 3. For the corners of the room, measurements are taken on the right side of the corner. When four points are measured, the following calculation is performed to calculate the correction value, and the exact length and angle of each point are determined. It is sufficient that the calculation can be performed at points other than 4 .

The four measurement positions are denoted by C. Length between BC, and M _'4. ∠CBO = α _'1 to. To calculate the length of L _1. In FIG. 5, the numerical values determined as a result of the measurement are:
L ′ ₁ , L ₄ , θ ′ ₄ . In addition, the spread angle θ of the laser beam.

[0023]

(Equation 3)

A line parallel to a straight line connecting the points 1 and 4 passing through the point O is defined as the X axis, and a straight line passing through the point O perpendicular to the X axis is defined as the Y axis. The coordinates of one point are (L ₁ · cos θ ₁ , L ₁ · sin
θ ₁ ).

[0025]

(Equation 4)

In FIG. 6, θ ₂ = (180−α ′ ₁ −θ ′ ₂ ) Therefore, the coordinates of the two points are (L ₂ cos θ ₂ , L ₂ sin
θ ₂ ) Similarly, the coordinates of the other measurement points are determined. In this way, when each coordinate can be measured, the measured value is calculated and the difference (habit) from the standard room is given. As an example, a case where the number of measurement points in one tatami mat is three in six mats will be described with reference to FIG. 1) The measuring machine 1 is installed near the center of the room, and the angle and distance from the measuring machine to the measurement point are measured, whereby the polar coordinates of each point can be determined. 2) Measurement point 1 ,
Consider a standard room in which a straight line passing through 1 , 4 at the time of measurement of 2 , 3 , and 4 is defined as one side and one point is a habit (0, 0). A difference (habit) in a required direction in the X-axis and Y-axis directions from the standard room is calculated and stored as data. 3) 1 , 5 ,
Each of the points 8 and 12 is a corner and requires a characteristic in both X and Y directions.
4) The points 2 , 3 , 4 , 9 , 9 , 10 and 11 need only the Y-direction error. 5) The points of 6 , 7 , 13 , and 14 need only the X-direction error.

The following method (means) can be adopted as a method for correcting a corner. That is, each one before and after the corner of the room
This is a method of measuring and correcting positions. For example, FIG.
Between the 6 tatami mats, the points D and E are measured at one corner as shown in FIG. When measurement of each point is completed sequentially, point E and
A straight line formula passing through two points and a straight line formula passing through points D and 14 are found, and an intersection 1 (X ₁ , Y ₁ ) of each straight line is obtained. The other corners 5 , 8 , 12 are found similarly. That is,

The measuring unit 5 is provided with a rotary encoder 3 for measuring an angle and a distance measuring means 2 for measuring a linear distance by a laser. At the installation position, the measuring unit 5 is rotated to measure the linear distance and angle to the measuring unit of the room by the measuring means 2 and the encoder 3, respectively, to measure the shape and dimensions of the room, and to correct the measured values. The corrected measurement is recorded, and the recorded data is read by an IC card or the like and transmitted to a tatami manufacturing machine such as a habit stitch sewing machine.

When a laser beam is applied to the center of the corner of a room,

[0035]

(Equation 7)

Therefore, θ ₂ is given by θ ₂ = (180−α ′ _1b −
θ ' ₂ ). Therefore, the coordinates of the two points are (L ₂ · cos
θ ₂ , L ₂ · sin θ ₂ ) Similarly, the coordinates of the other measurement points are determined. As described above, when each coordinate can be measured, the measured numerical value is calculated to obtain a difference (habit) from the standard room. Referring to FIG. 10, 1) the measuring machine 1 is installed near the center of the room, and the angle and distance from the measuring instrument to the measurement point are measured, whereby the polar coordinates of each point are determined. 2) Consider a standard room in which a straight line passing through 1b and 5a is defined as one side when measuring points 1a , 1b , 2 , 3 , 4 , and 5a are measured, and one point is a habit (0, 0). A difference (habit) in a required direction from the standard room in the X-axis and Y-axis directions is calculated and stored as data. 3) Each of the points 1 , 5 , 8 , and 12 is a corner and requires a characteristic in both X and Y directions. 4) Each of the points 2 , 3 , 4 , 9 , 9 , 10 and 11 requires only the Y-direction error. 5) For points 6 , 7 , 13 , and 14 , only the X-direction error is required.

Next, the notch of the room will be described with reference to FIGS.

Notch 5 _cd in A, 5 _ef, 5 similarly to the measurement of the coordinates corners of each point _gh 5 _cd in Fig. _{11 (L 5d · cosθ 5d,} L 5c · sinθ 5C) 5 ef (L 5e · cosθ 5e , L _5f · sin θ _5f ) 5 _gh (L _5h · cos θ _5h , L _5g · sin θ _5g ).

In this case, the coordinates of 5 are (L _5h · cos θ _5h ,
L _5c · sin θ _5c ). 11, the notch B will be described. This notch B is used when one side is narrower than the width of the laser beam. In the example of FIG. 11, the position is 8 . In FIG. 12, it is known that the diffusion angle of the spot light of the laser beam is constant. The light diffusion angle is θ ₀ . Since the measured value of the laser light is the strongest part of the reflected light, if the center of the spot light is considered, the correction of the notch angle portion is as follows, as shown in FIGS. 11 and 13 as an example.
