Description

  The present invention relates to an apparatus used in an operation for defining an outer peripheral contour of a flat plate such as a table plate or a desk plate. More specifically, the present invention relates to an apparatus used in an operation of demarcating the outer peripheral contour of the flat plate in order to obtain the outer peripheral contour of the rug laid on the flat plate.

There is a business of cutting and providing a sheet such as a resin sheet so as to conform to the outer peripheral contour of a flat plate to be laid, such as a table board, a desk board, and a loading platform. In that business, it is necessary to accurately define the outer peripheral contour of the target flat plate.
That is, in the case of a standard table plate or the like, the shape and dimensions of the outer peripheral contour are also determined, and therefore, it may be cut according to the shape. Therefore, it is necessary to measure a plate or the like to define the outer peripheral contour.

  JP-A-2006-289560 (Patent Document 1) can be cited as a technique for cutting and providing a sheet according to the shape of the target flat plate. In the technique of this publication, a sheet having a prescribed size such as A4 paper is placed on the target flat plate and photographed, and the outer periphery of the target flat plate is based on a comparison between the A4 paper and the target flat plate on the photographed image. I have an outline.

JP 2006-289560 A

  The technique of Patent Document 1 has a problem in accuracy due to variations in lens distortion of individual photographing devices, but not only that, but also the edge cross-sectional shape of the target flat plate (cut by a plane perpendicular to the target flat plate surface). In other words, the outer peripheral contour of the rug cannot be well defined.

That is, the edge cross-sectional shape of the target flat plate has various shapes as shown in FIG. For this reason, depending on the edge cross-sectional shape of the target flat plate, for example,
(A) The edge of the rug 92 is matched with the edge tip 10con of the target flat plate 10 (second in FIG. 5B; see);
(B) The edge of the rug 93/95/95 is matched with the boundary portion where the edge curved surface of the target flat plate 10 / 10D / 10D continues to the flat plate surface (the third, fifth, and FIG. 5 (c) in FIG. 5B). );reference);
From the above, it must be decided appropriately in consideration of appearance and feeling of use.
In other words, in the relationship between the rug and the target flat plate, the position where a good appearance can be obtained and the position where a good feeling of use can be obtained are indicated by the edge area of the target flat plate (edge edge to edge curved surface / border portion of the flat plate surface). It must be decided appropriately from among the parts.

However, in the case of the technique of Patent Document 1, the position detected as the outer peripheral contour of the target flat plate is the outermost edge of the target flat plate in the photographed image, and this outermost edge is the edge region (edge tip to edge curved surface / flat plate). The position of the boundary portion of the surface is different depending on the shooting angle or the like. For example, when photographing from directly above a certain edge position, the edge tip is considered to be the outermost edge with respect to the certain edge position. That is, the edge tip is detected as the outer contour. However, at the edge position on the opposite side (edge position on the opposite side across the center of the flat plate), the tangent drawn from the camera to the edge position on the opposite side is not taken as a result of shooting from diagonally above. The part which touches the marginal region is the outermost edge. That is, the part where the tangent drawn from the camera touches is detected as the outer contour.
As described above, even if the edges of the same plate are different from each other in the shooting angle depending on the position with respect to the camera, the edge tip is detected as the position of the outer peripheral contour, or the part where the tangent drawn from the camera touches is detected as the position of the outer peripheral contour. The trouble that it is done occurs.

  The present invention has been made in view of the above-described circumstances, and the position to be the outer peripheral contour of the rug in consideration of appearance, usability, and the like, the edge region of the target flat plate (edge tip to edge curved surface / boundary portion of flat plate surface) It is aimed to be able to be appropriately defined from within.

Embodiments of the present invention will be described below with reference to the drawings.
(1) System Overview As shown in FIG. 1, the system includes a pair of fixed-side devices 21 and 22 and a flat plate contour defining device (moving-side device) 30. The pair of fixed-side devices 21 and 22 are respectively placed at arbitrary positions on the flat plate 10 and are then retained at the respective positions. The moving-side device 30 is moved by the user so that the contact portion of the vertical member 302 is brought into contact with the edge tip 10con of the flat plate 10 and circulates along the edge of the flat plate 10.

(2) Movement-side device The movement-side device 30 includes a vertical member 302 and a horizontal member 301 configured integrally with the vertical member 302. The horizontal member 301 is provided so as to extend in a direction orthogonal to the vertical member 302, and the horizontal member 301 is the flat plate 10 in a state where the contact portion of the vertical member 302 is in contact with the edge tip 10 con of the flat plate 10. It can be closely supported by the upper surface. That is, when the horizontal member 301 is placed on the flat plate 10 and the contact portion of the vertical member 302 is brought into contact with the edge tip 10con of the flat plate 10, the moving device 30 is positioned with respect to the flat plate 10. At this time, the moving device 30 is also positioned with respect to the pair of fixed devices 21 and 22 arranged on the flat plate 10.

  As shown in FIG. 4, the moving side device 30 includes an indicator needle 303 and a needle support mechanism 304 that supports the indicator needle 303 so as to be movable along the lateral member 301. That is, the horizontal member 301 is provided with a guide 304g extending in the same direction as the horizontal member 301, and a slider 304s for supporting the indicator needle 303 is slidably provided on the guide 304g. The guide 304g and the slider 304s constitute a needle support mechanism 304, whereby the indicator needle 303 can be moved along the lateral member 301.

  In a state where the contact portion of the moving side device 30 is positioned in contact with the edge tip of the flat plate 10, as shown in FIG. 2, the indicator needle 303 is moved by an arbitrary distance t0 from the edge tip of the positioned edge. A position T0 entering the inside of the flat plate 10 can be indicated. That is, the user operates the indicator needle 303 to move the guide needle 304g and move it at an arbitrary distance t0 in the inward direction of the flat plate. Can be instructed. Here, the flat plate inner direction is preferably a direction orthogonal to the tangential direction of the positioned edge tip. In other words, when the user manually moves and positions the moving-side device 30, it is desirable that the lateral member 301 is positioned so as to face a direction perpendicular to the tangential direction of the edge tip.

  The movement side device 30 is provided with a posture regulating member (not shown), and in the positioned state, the transverse member 301 is configured to accurately face the edge tip or the direction perpendicular to the tangential direction of the edge tip (normal direction). May be. In that case, the above-described flat plate inner side direction is a direction orthogonal to the tangential direction of the positioned edge tip. In the configuration provided with this posture regulating member, when the moving side device 30 is moved along the edge tip of the flat plate 10 with the indicating needle 303 fixed (fixed at a distance t0), the indicating needle 303 instructs. The locus (contour) of the position T0 is a curve obtained by moving the edge tip curve of the flat plate 10 in the flat plate inner direction by the distance t0. That is, it becomes a curve along the edge tip of the flat plate 10. Even in the configuration without the posture regulating member, the position T0 indicated by the indicator needle 303 is sufficiently close to the edge tip, so the distance t0 is sufficiently small in the relative comparison with the size of the flat plate 10. As a result, approximately, similarly, a curve along the edge tip of the flat plate 10 is obtained.

  The moving apparatus 30 may be provided with a writing tool 303a as shown in FIG. FIG. 4 illustrates a configuration in which the indicator needle 303 is supported by a slider 304s slidably provided on the guide 304g, and the writing instrument 303a is supported via attachments 303b and 303c integrated with the indicator needle 303. ing. As the writing instrument 303a, any writing instrument that can draw a line on a pattern paper, such as a pencil, a bow pen, or a drawing pen, can be used.

  When the pattern paper is laid on the flat plate 10 and the moving-side device 30 with the writing tool 303a attached is moved along the edge tip of the flat plate 10 with the indicating needle 303 fixed (fixed at a distance t0) as described above, A curve along the edge tip of the flat plate 10 is drawn on the pattern paper by the writing tool 303a. You may comprise so that adjustment of the position (relative position with respect to the indicator needle | hook 303) of the writing instrument 303a is possible. When configured to be adjustable, by setting the position appropriately, a desired interval along the locus (contour line) of the position T0 indicated by the indicating needle 303 on the pattern paper is set appropriately. You can draw a curve to keep. For example, when the writing instrument 303a is set at a position W1 that is further a distance tw from the position T0 of the indicating needle 303 toward the inside of the flat plate, the distance between the edge tip curve and the distance “t0 + tw” is set along the edge tip curve of the flat plate 10. The curve to keep can be drawn on the pattern paper.

  Therefore, since the position T0 on the flat plate 10 indicated by the indicator needle 303 is a portion that is too close to the edge tip and deviates from the flat surface to form a curved surface, the contour line can be satisfactorily drawn on the pattern paper laid thereon. If not, after drawing a curve along the edge tip curve of the flat plate 10 and maintaining the distance from the edge tip curve to the distance “t0 + tw” on the pattern paper, the pattern paper is placed on a flat plane and the curve is moved outward. By drawing a curve widened by the distance tw, it is possible to obtain a pattern with a desired contour for cutting a resin sheet.

  In this moving side device 30, a rolling member (supported by a vertical member 302 so as to be rotatable forward and backward by a shaft 306a so that the device can be smoothly moved along the edge tip of the flat plate 10). Roller) 306 is provided, and the lateral member 301 is also provided with a rolling member (roller) 305 that is pivotally supported by a shaft 305a so as to be rotatable forward and backward. When the lateral member 301 of the moving side device 30 is pressed against the upper surface of the flat plate 10 and the vertical member 302 is moved along the edge tip of the flat plate 10 while being pressed against the edge tip of the flat plate 10, a rolling member (roller) 306 is used. Is kept in contact with the edge tip of the flat plate 10 while rolling, but this contact portion is the contact portion.

(3) Cooperation with Fixed Side Device In the system shown in FIG. 1, a pair of fixed side devices 21 and 22 whose distances are known is used as a reference point, and the distance from the two reference points to the moving side device 30 is calculated. Each position is obtained by measurement, and the position of the moving side device 30 viewed from the pair of fixed side devices 21 and 22 is determined using the principle of triangulation. The distance to be measured is the distance d210 between the signal terminal 210m of the fixed side device 21 and the signal terminal 300m of the moving side device 30, and the distance d220 between the signal terminal 220m of the fixed side device 22 and the signal terminal 300m of the moving side device 30. It is. Therefore, the position determined by the principle of triangulation is the position of the signal terminal 300m, which is different from the position T0 indicated by the indicator hand 303. In order to determine the designated position T0 (contour position T00), the distance d21 between the signal terminal 210m and the contour position T00 of the stationary device 21 and the distance d22 between the signal terminal 220m of the stationary device 22 and the contour position T00. Is desired. In this system, the distances d210 and d220 are obtained by measurement, and these are appropriately corrected using the distance t2 (see FIG. 2) between the contour position T00 and the signal terminal 300m. In the movement side device 30, the signal terminal 300m may be provided at a position that can be regarded as the same as the indicating needle 303. In this configuration, no correction is necessary, and the distances d21 and d22 can be obtained by measurement.

  As shown in FIG. 2, the distance t2 between the contour position T0 and the signal terminal 300m used for correction is obtained by subtracting the distance t0 between the contact portion and the contour position T00 from the distance t3 between the contact portion and the signal terminal 300m. Value. Here, the distance t3 is a distance between the contact portion and the signal terminal 300m, that is, a distance between parts fixed on the moving side device 30, and is a predetermined (known). Therefore, if the distance t0 is known, the distance t2 can be obtained.

  On the other hand, as described above, the pointing needle 303 of the moving device 30 is a member that indicates a desired position on the flat plate 10. When the pointing needle 303 points to a certain position T0 on the flat plate 10, the position of the pointing needle 303 in the moving side device 30 is defined as the contour position T00, and a distance (corresponding to the position T00) (Distance from the contact portion) t0 is detected and input to a control unit (CPU or the like) 308 (see FIG. 3) of the moving apparatus 30. Thereby, the control unit 308 can obtain the distance t2 between the contour position T00 and the signal terminal 300m by calculation. As a method for detecting the contour position T00 (distance t0), for example, a known method such as a method for detecting the distance t0 as an electric resistance value can be used.

  In order to realize the above-described function, that is, the function of determining the contour position T00 viewed from the pair of fixed-side devices 21 and 22, the moving-side device 30 includes a control unit 308 and a position setting unit 309 as shown in FIG. The transmitter / receiver 307 is provided. The fixed-side device 21 includes a control unit 2108, a calculation unit 2108a, transmission / reception units 2107 and 2107 ′, and a distance value setting unit 2109. The fixed-side device 22 includes a control unit 2208, transmission / reception units 2207 and 2207 ′, and a distance. A value setting unit 2209 is included. Details of the functions of these units will be described in the system procedure section below.

(4) System procedure 1 (FIG. 6)
The procedure executed in the system of FIGS. 1 and 3, which is composed of the moving device 30, the first fixed device 21, and the second fixed device 22, will be described with reference to FIG. 6.
In FIG. 6, every time an input operation for position designation is performed by the user in the moving side device 30, the contour position T00 at the time of the input operation viewed from the fixed side devices 21 and 22 is determined. It is stored in a predetermined storage device (not shown) of one or more devices 21/22/30.

  The first fixed side device 21 and the second fixed side device 22 are arranged on the flat plate 10, and a predetermined operation input for instructing distance measurement is made in any of the devices 21/22/30. Then, the distance d0 between the first fixed device 21 and the second fixed device 22 is measured (S101). This distance d0 is similar to the distance d210 and distance d220, which will be described later, for example, between the signal terminals 210m and 220m of the first and second fixed side devices 21 and 22, and the synchronization signal (radio signal) and the ultrasonic signal. Can be obtained based on the arrival time difference. The first fixed side device 21 and the second fixed side device 22 are configured as an integrated device, the distance between the signal terminal 210m and the signal terminal 220m is fixed, and the distance d0 is set to a fixed value. You may comprise so that it may hold | maintain beforehand in the memory | storage device of the 2nd stationary-side apparatus 21 and 22.

  In step S112, the position designation operation on the moving side device 30 is on standby. The position designation operation is a predetermined input operation for confirming the instruction performed after the user designates a desired position T0 on the flat plate 10 with the indicating needle 303 in the movement side device 30.

If a position designation operation is detected (YES in S112), the process proceeds to step S121.
Step S <b> 121 is a step of defining a contour position T <b> 00 as a position in the moving side device 30 according to the designated position T <b> 0 designated as the position on the flat plate 10. That is, when the position designation operation is detected, the pointing needle 303 indicates the position (desired position) T0 on the flat plate 10, and the pointing needle 303 is guided by the guide 304g in relation to the guide 304g of the moving side device 30. When it is in the position T00, it is set as the contour position T00 (S121).

  In step S121, the distance t0 between the contact portion and the contour position T00, that is, the distance t0 from the contact portion to the contour position T00 when the contact portion is used as the reference position is detected. As described above, the moving device 30 has a function of detecting the relative position of the indicating needle 303 in the guide 304g as a distance from the contact portion (see the position setting unit 309 in FIG. 3; see FIG. 3). ) By this function, the distance t0 from the contact portion to the contour position T00 is detected.

  Next, the process proceeds to step S123. In step S123, the distance t2 from the contour position T00 to the distance measuring end 300 is calculated from the distance t0 from the contact portion to the contour position T00 and the distance t3 from the contact portion to the distance measuring end 300. The distance measuring end 300 is an end portion on the side of the moving side device 30 in the distance measurement with the fixed side devices 21 and 22. In this example, a synchronization signal (radio signal) and an ultrasonic signal are transmitted and received. It matches the signal terminal 300m. It is assumed that the distance t3 from the contact portion to the distance measuring end 300 is a constant and is held in advance by the control unit 308.

Next, the process proceeds to step S141, and a distance d210 between the distance measuring end 300 of the moving device 30 and the signal terminal 210m of the fixed device 21 is obtained. Here, a synchronization signal (radio signal) and an ultrasonic signal are simultaneously transmitted from the signal terminal 300m of the mobile device 30 and obtained based on a difference in reception time at the signal terminal 210m of the fixed device 21. Since the distance measurement method using the synchronization signal (radio signal) and the ultrasonic signal is well known, further explanation is omitted.
Similarly, a distance d220 between the distance measuring end 300 (signal terminal 300m) of the moving device 30 and the signal terminal 220m of the fixed device 22 is obtained.
Note that the synchronization signal (wireless signal) and the ultrasonic signal may be transmitted from the fixed devices 21 and 22 and received by the mobile device 30.
Further, instead of distance measurement using a synchronization signal (wireless signal) and an ultrasonic signal, a known distance measurement method such as distance measurement using an infrared signal or distance measurement using a laser may be used.

  Next, the process proceeds to step S143, and the position of the signal terminal 300m (ranging end 300) of the moving side device 30 as viewed from the fixed side devices 21 and 22 is determined by the principle of triangulation. That is, the distance d0 between the fixed side devices 21 and 22 detected and held in step S101, and the distance d210 between the signal terminal 210m of the fixed side device 21 and the signal terminal 300m of the moving side device 30 calculated in step S141. The position of the signal terminal 300m (ranging end 300) with reference to the fixed side devices 21 and 22 is determined from the distance d220 between the signal terminal 220m of the fixed side device 22 and the signal terminal 300m of the moving side device 30. .

  Next, the process proceeds to step S145, and the distance between the contact portion and the contour position T00 calculated in step S123 at the position of the signal terminal 300m (ranging end 300) of the moving side device 30 as viewed from the fixed side devices 21 and 22. Correction based on t2 is performed. Thereby, the contour position T00 viewed from the fixed side devices 21 and 22 is determined. Thereafter, the distance t2 is cleared. The contour position T00 is also a designated position T0 on the flat plate 10 when the moving device 30 is at the position. Therefore, the moving side device 30 is moved along the edge tip of the flat plate 10, stopped at an appropriate position interval, and the above procedure is repeated, so that the contour position of the moving side device 30 viewed from the fixed side devices 21 and 22 is obtained. T00, that is, the designated position T0 on the flat plate 10 can be accumulated. In other words, it is possible to obtain an outline as a line connecting a large number of designated positions T0.

  When a contour line that circulates along the edge tip curve of the flat plate 10 is obtained (YES in S151), the procedure of FIG. 6 ends. Whether or not the contour line has been obtained may be determined by the user who handles the moving device 30 or whether or not a closed curve can be drawn on the fixed device 21 or the like by a line connecting the specified position T0. It may be determined by providing a function such as.

The correction in step S145, that is, the correction for determining the contour position T00 based on the distance t2 between the contact portion and the contour position T00 will be described with reference to FIG.
As described above, in steps S141 to S143 in FIG. 6, the position of the distance measuring end 300 (signal terminal 300m) of the moving side device 30 is determined with reference to the signal terminals 210m and 220m of the fixed side devices 21 and 22. ing. However, this position is different from the position T0 (contour position T00) designated by the pointing needle 303, and is a position separated from the position T0 (contour position T00) by a distance t2. For this reason, correction is necessary. It should be noted that the correction is not necessary in the case of the configuration in which the signal terminal 300m is provided at a position that can be regarded as the same as the indicating needle 303 in the movement side device 30, that is, in the configuration in which “t2≈0”. It is as follows.

  As shown in FIG. 1A, the moving side device 30 circulates around the flat plate 10 along the edge tip 10 con of the flat plate 10. In FIG. 9, when the signal terminals 210 m and 220 m of the fixed side devices 21 and 22 are both ends of the base of the triangle and the signal terminal 300 m of the moving side device 30 is the apex, both base angles form an acute angle. In general, the contour position T00 can be determined by extending the triangle in the direction of the apex. That is, the position (position on the circle r having the radius t2) is determined so as to increase both base angles and extend the lengths of both sides (distances d210, d220) by the distance t2 from the signal terminal 300m. The contour position T00 can be set. The distance d21 is a distance between the signal terminal 210m and the contour position T00, and the distance d22 is a distance between the signal terminal 220m and the contour position T00.

In a range where one of the both base angles forms an obtuse angle, the contour position T00 can be determined by extending the triangle in the direction of the apex so that the obtuse angle is relaxed (the angle is reduced). That is, a position (a position on a circle r having a radius t2) that is away from the signal terminal 300m by a distance t2 is determined so that the base angle of the acute angle is expanded and the base angle of the obtuse angle is narrowed, and the position is defined as the contour position T00. It can be. The distance d21 ′ is a distance between the signal terminal 210m and the contour position T00, and the distance d22 ′ is a distance between the signal terminal 220m and the contour position T00.
In the above correction, the distance t2 is sufficiently small compared to the size of the flat plate 10 in both cases where both the base angles are acute angles and where either one of the base angles forms an obtuse angle.

(5) System procedure 2 (FIG. 7)
A procedure executed in the system of FIGS. 1 and 3 and slightly different from FIG. 6 will be described with reference to FIG. Note that the same processing as in FIG. 6 is indicated by the same step number, and description thereof is omitted.

  In FIG. 7, every time the position T0 on the flat plate 10 is designated (YES in S111), the distance t0 between the contact portion and the contour position T00 is detected (S121), and between the contour position T00 and the signal terminal 300m. A distance t2 is determined. The designation of the position T0 on the flat plate 10 may be configured to be performed at predetermined time intervals, for example, or may be performed each time the moving-side device 30 that circulates along the edge tip of the flat plate 10 stops. You may comprise.

  Further, in FIG. 7, at every determination timing of the contour position T00 (TES in S131), on the condition that the distance t2 between the contour position T00 and the signal terminal 300m is maintained (YES in S133), the signal terminals 210m to The distance d210 between the signal terminals 300m and the distance between the signal terminals 220m and 300m are obtained (S141), and the position of the signal terminal 300m viewed from the fixed side devices 21 and 22 is determined by the principle of three-side surveying. (S143) The contour position T00 is determined and stored by correction based on the distance t2 between the contour position T00 and the signal terminal 300m (S145).

(6) Processing of moving side device and fixed side device (FIG. 8)
FIG. 8 is a flowchart showing the procedure of FIG. 6 executed by the system of FIGS. 1 and 3 in a distributed manner to the mobile device 30 and the pair of fixed devices 21 and 22. In FIG. 8, the processing in step S <b> 141 (processing for obtaining the distances d <b> 210 and d <b> 220) in FIG. 6 is the same as in step S <b> 124 m of the moving side device 30, steps S <b> 124 f to S <b> 142 f of the stationary side device 21, and the stationary side device 22. Is distributed to the processing.
Note that FIG. 8 is an example, and it is needless to say that the processing can be distributed differently from that in FIG. 8 to realize the same function.

(7) Others In the above description, the mechanism of the fixed-side devices 21 and 22 is omitted. However, any mechanism may be used as long as the mechanism can achieve the above-described function. For example, the fixed-side devices 21 and 22 may be configured by mounting an application having the above-described functions on a smartphone or the like that includes a terminal for transmission and reception with the mobile-side device 30.

  In the above description, the fixed-side devices 21 and 22 are both arranged on the flat plate 10. However, as long as they are on the same plane as the flat plate 10, the fixed plate 10 may be arranged at a position away from the flat plate 10. An example is a fixed-side device 22 indicated by a virtual line (two-dot chain line) in FIG.

  Further, in the above, the processing in the fixed side devices 21 and 22 and the mobile side device 30 is completed by these devices. For example, part of the processing (function) is performed remotely via the Internet or the like. It may be configured to be executable. As a part of the processing (function), a part or all of the function of the calculation unit 2108a of the fixed-side device 21 of FIG. 3 can be exemplified.
