Notify the part 365.

  Further, the construction verification unit 363 compares the construction line with the construction data 7 and determines whether the construction line is drawn with the correct size, concentration, and arrangement. Then, the construction verification unit 363 notifies the progress management unit 364 and the construction image drawing unit 365 of the arrangement of a construction line (hereinafter referred to as an error line) which is not drawn with the correct size, density or arrangement.

  The progress management unit 364 calculates the line length of the installed line specified by the installation verification unit 363 for each line part. Then, the progress management unit 364 calculates the progress rate for each worker based on the plan data 8, and notifies the setup image drawing unit 365 of the calculated progress rate for each worker.

In the progress screen 40, the positions of all workers, the line parts for which the selected worker is in charge of setting, and the line parts for which other workers are in charge are reflected in the entire image of the line to be set up. The progress rate of the selected worker is displayed as a progress bar. Further, on the progress screen 40, based on the order of the plan data 8, information indicating the movement to the next line part is displayed by an arrow or the like. The progress screen 40 shown in FIG. 6 is the progress screen 40 of Mr. A. Line parts for which Mr. A is in charge of setting (The guidance line on the already constructed line is a solid line, and the guidance line at a place where the line is not drawn is a dotted line ) Is highlighted in bold, the guidance line for Mr. B's department is shown by a dashed dotted line, and the guidance line for Mr. C's department is shown by a dotted line.

  Next, the setting assistance operation by the setting assistance system of the present embodiment will be described in detail with reference to FIGS. 4 to 8. In the following description, it is assumed that the installation data 7 shown in FIG. 4 and the plan data 8 shown in FIG. 5 are created by the installation plan management device 2.

  First, actual reference poles 1a to 1d are installed in the hall G at the arrangement positions of the reference poles 1a to 1d in the construction data 7, respectively. The installation positions of the reference poles 1 a to 1 d function as known points in the actual measurement data 5. The reference poles 1a to 1d are installed so that the central axis of the base 11 is vertical. As a result, the conditions are the same regardless of which direction the reference poles 1a to 1d are viewed. Although it is preferable to place the central axis of the base portion 11 vertically as accurately as possible, it is needless to say that a certain effect can be obtained even if it is not strictly perpendicular.

  Next, the worker wears the glasses-type terminal 3 and captures at least two of the four reference poles 1a to 1d in the field of view. As a result, as shown in FIG. 7, the view field imaging unit 31 captures a view field image including at least two of the four reference poles 1 a to 1 d. Hereinafter, as shown in FIG. 7, an example in which the reference pole 1b and the reference pole 1d are included in the view image will be described.

  The reference pole 1 b in the view image and the reference pole 1 d are detected by the reference pole detection unit 361. The reference pole detection unit 361 distinguishes and detects the reference pole 1 b and the reference pole 1 d by searching the identification unit 14 that matches the matching data of the reference data 4 in the view image.

  The current position specifying unit 362 uses the detected reference pole 1 b and the reference pole 1 d when the reference pole detection unit 361 detects the two reference poles 1 b and the reference pole 1 d, and uses the measured data 5 The current position and posture of the glasses-type terminal 3 in the inside are specified as current position information.

  The current position specifying unit 362 calculates the distance Lb to the reference pole 1 b based on the base length Xb of the reference pole 1 b in the view image and the base length X of the reference pole 1 b in the reference data 4 Based on the base length Xd of the reference pole 1 d and the base length X of the reference pole 1 d of the reference data 4, the distance Ld to the reference pole 1 d is calculated. Thereby, as shown in FIG. 8, the current position of the glasses-type terminal 3 in the hall G (measured data 5) is specified.

  Further, the current position specifying unit 362 specifies the direction in which the glasses-type terminal 3 is facing based on the position in the left-right direction in the view image of the reference pole 1 b or the reference pole 1 d. Further, the current position specifying unit 362 specifies the tilt of the glasses-type terminal 3 based on the vertical position of the reference pole 1 b or the reference pole 1 d in the view image. Note that the current position specifying unit 362 may specify the posture in which the glasses-type terminal 3 is facing by the outputs of the acceleration sensor 37 and the electronic compass 38.

  While at least two of the four reference poles 1a to 1d are included in the view image, identification of current position information by the current position identification unit 362 is performed at any time according to the movement of the worker or the change in the line of sight. It will be. When the number of reference poles 1a to 1d included in the view image is less than two, the current position specifying unit 362 follows the current position information based on the output of the acceleration sensor 37 and the output of the electronic compass 38. Estimate.

  The construction image drawing unit 365 draws a guide line as an AR image based on the current position information specified or estimated by the current position specification unit 362 and the construction data 7, and as shown in FIG. Display on the part 32. The AR image example shown in FIG. 9 is an AR image for Mr. A, in which the line parts for which Mr. A is in charge of setting (the guide line in the place where the line is not drawn are dotted) are highlighted The guide lines on the installed line for Mr. B are shown by thin solid lines, and the guide lines on the error line are shown by thin dashed lines. In addition, since the installed line exists in the view image, the guide line of the corresponding part may be omitted in the AR image. Moreover, when displaying a guide line on the installation completed line in AR image, it is good to make it display with a color different from the installation completed line of a visual field image.

  When line drawing is performed, the guidance line is displayed as an AR image on the AR image display unit 32 so as to be superimposed on the field of view of the worker. Therefore, the operator can draw a line with the line car in accordance with the AR image. In addition, although a line car is usually used by forward pressing, in that case, since the white line and the AR image of the white line drawn when it turns around appear to overlap, it can be checked whether or not it has been correctly drawn.

  Further, in the AR image, as shown in FIG. 9, a guide line on an error line which is not drawn with the correct size, density or arrangement is drawn in distinction from other places. Therefore, only by looking over the place G, it is possible to easily grasp the location which needs to be repaired. For example, if it is necessary to complete the line repair in a limited short time, such as between competitions, it is not necessary to redraw all the lines, and clearly identify the parts that need to be repaired and the parts that do not need to be repaired. By displaying on the AR image display unit 32, it is possible to achieve more efficiency.

  In the present embodiment, four reference poles 1a to 1d are installed, but as described above, the number of reference poles may be two or more, and the number of reference poles to be installed in the hall G Should be set appropriately according to the venue G.

  In the present embodiment, the installation positions of the reference poles 1 a to 1 d are known points in the actual measurement data 5. Therefore, the reference poles 1a to 1d must be installed exactly as set up data 7. However, accurately measuring the installation positions of the reference poles 1a to 1d is a time-consuming operation.

  Therefore, by providing the setting image drawing unit 365 with a function of drawing the outline of the actual measurement data 5, ie, the outline of the hall G, as an AR image based on the current position information, the reference pole 1a can be obtained without accurately measuring the installation position. It becomes possible to correctly install ~ 1d as set up data 7. The procedure is shown below.

  First, the operator visually installs two of the reference poles 1a to 1d, for example, the reference poles 1a and 1b at set positions of the installation data 7. Next, the worker wears the glasses-type terminal 3 and captures the two reference poles 1a and 1b in the field of view. Thus, the current position specifying unit 362 specifies temporary current position information on the assumption that the reference poles 1a and 1b are correctly installed.

  Next, the construction image drawing unit 365 draws the outline of the measurement data 5 based on the temporary current position information and causes the AR image display unit 32 to display the outline.

  As a result, the worker can recognize the deviation between the AR image of the contour of the venue G and the contour of the actual venue G. Then, by adjusting the installation positions of the reference poles 1a and 1b so that the two coincide with each other, the reference poles 1a and 1b are correctly installed as the installation data 7.

  As for the other two reference poles 1c and 1d, since the correct current location information is specified by using the reference poles 1a and 1b, the AR images of the reference poles 1c and 1d drawn by the construction image drawing unit 365 are used. It can be installed and used.

  Furthermore, in the present embodiment, the glasses type terminal 3 is provided with the terminal storage unit 34, the reference pole detection unit 361, the current position specifying unit 362, the construction verification unit 363, the progress management unit 364 and the construction image drawing unit 365. Although an example has been described, all or a part of these configurations may be provided on the construction plan management device 2 capable of communicating with the glasses-type terminal 3 or on a network.

A current position specifying unit 362 that specifies the current position and posture of the glasses-type terminal 3 in the actual measurement data 5 as current position information based on the sizes and positions of 1a to 1d, and the hall image by analyzing the view image. A guidance line for guiding the setting position of the line is drawn as an AR image and displayed on the AR image display unit 32 based on the construction verification unit 363 specifying the already drawn construction line and the current position information and the construction data 7 The establishment image drawing unit 365 distinguishes the guidance line on the installation line from the guidance line at a place where the line is not drawn and draws the guidance line.
With this configuration, the augmented reality image of the line to be set up can be superimposed and displayed on the field of view of the worker, so that the worker can draw a line while looking at the augmented reality image, thus setting up the venue It is possible to efficiently assist the operator who performs.

Further, according to the present embodiment, the construction verification unit 363 compares the construction line with the construction data 7 to determine whether the line is drawn correctly, and the construction image drawing unit 365 correctly Guidelines on the pre-established lines are drawn separately from other parts.
