  According to a seventh aspect of the present invention, there is provided an inspection report creating program that causes a computer to function as the acquisition unit, the generation unit, and the display unit according to the sixth aspect.

  According to the present invention, it is possible to create an easy-to-use inspection report in the preparation of an inspection report using a three-dimensional design value of an inspection object and three-dimensional measurement values at a plurality of measurement points.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, an inspection result document creating apparatus including a computer will be described as an example.
As shown in the functional block diagram of FIG. 1, the inspection result document creating apparatus 1 includes an image display unit 2 such as a liquid crystal monitor, a control unit 3, an operation unit 4 including a mouse and a keyboard, design values and measurement values described later, and the like. The computer 10 includes a storage unit 5 that stores information, a 3D image generation unit 6 that generates a 3D image based on a design value, and a communication unit 7 that is connected to a network or an external device to acquire information. It is assumed that the control unit 3 stores various programs in advance in an internal memory (not shown).

First, the control unit 3 acquires a three-dimensional design value of the inspection object and three-dimensional measurement values at a plurality of measurement points. The design value and the measured value are acquired by a user operation via the operation unit 4 or are acquired via the communication unit 7.
In the present embodiment, a series of descriptions will be given with the inspection object S shown in FIG. 2 as the inspection object. The inspection object S has a cylindrical cavity at the center of the rectangular parallelepiped as shown in the perspective view of FIG. FIG. 2B is a development view of the inspection object S. Note that points A to R in FIG. 2 are measurement points. FIG. 3 shows a table of design values and measurement values. In FIG. 3, “measurement point” indicates the above-described points A to R, and “direction” indicates the measurement direction. The “design value” indicates the design value of the inspection object S, and the “upper limit tolerance” and the “lower limit tolerance” indicate tolerances specified by the user. The “actually measured value” indicates a measured value when the inspection object S is actually measured, and this actually measured value corresponds to the “measured value” in the claims. “Error” indicates a difference between the “design value” and the “measured value”. Further, “determination” indicates the result of the pass / fail determination based on “upper limit tolerance”, “lower limit tolerance”, and “error”. Since the specific method of pass / fail judgment is the same as that of the known technique, the description thereof is omitted. In addition, the result of the pass / fail determination may be acquired together with the design value and the measured value, or the pass / fail determination may be performed by the control unit 3. The “reference point” indicates a point serving as a reference for the “design value” and the “measured value”.

As described above, when the three-dimensional design value of the object to be inspected and the three-dimensional measurement values at a plurality of measurement points are acquired, the control unit 3 stores the acquired information in the storage unit 5 and then via the operation unit 4. Based on the user operation, an inspection report is created and displayed on the image display unit 2 and stored in the storage unit 5.
The inspection report is composed of 3D images and measurement values at a plurality of measurement points. Therefore, the control unit 3 first generates a 3D image of the inspection object S via the 3D image generation unit 6. The 3D image is created in a format such as XVL format. Since a specific method for generating a 3D image is the same as that of the known technique, the description thereof is omitted.

Then, the control unit 3 displays an inspection report based on a user operation via the operation unit 4.
(1) Display based on reference point When the reference point at the time of automatic measurement is not uniform, display based on the reference point is performed in order to clarify the reference point for each measurement point.

  As shown in the table of FIG. 3, the inspection object S is measured using any one of points A, E, J, and N as a reference point. Therefore, as shown in FIG. 4, the control unit 3 displays the icon b indicating the reference point on the image display unit 2 together with the 3D image a generated by the 3D image generation unit 6 so that the user can select the reference point. To do. FIG. 4 shows an example when the point A is selected. The control unit 3 displays a coordinate axis c (XYZ coordinate system) based on the point A on the 3D image a. Further, the point A is indicated by ◎, the measurement point based on the point A is indicated by ●, and the measurement point based on another point is indicated by ◯. Also, below the 3D image a, design values and actual measurement values at the measurement points with the point A as a reference are displayed in the form of Table d. The coordinate axis c is obtained based on the design value.

  For example, when the point J is selected as the reference point by the icon b, the control unit 3 displays the coordinate axis e (θRZ coordinate system) based on the point J on the 3D image a as shown in FIG. To do. Further, the point J is indicated by ◎, the measurement point based on the point J is indicated by ●, and the measurement point based on another point is indicated by ◯. Also, below the 3D image a, design values and actual measurement values at measurement points with reference to the point J are displayed in the form of Table f. The coordinate axis e is obtained based on the design value.

Note that all reference points may be displayed simultaneously without selecting a reference point using the icon b. In such a case, it is preferable to display the reference points and coordinate axes of the respective measurement points by clarifying the display of marks and colors on the 3D image a.
(2) Display based on measurement direction When measurement is performed from a plurality of directions, display based on the measurement direction is performed in order to obtain a single inspection report.

  As shown in FIG. 2, the inspection object S has measurement points (points E, F, G, H, N, P, Q, R) on the back surface EFGH when the surface ABCD is the front surface. Therefore, the measurement is performed from a plurality of directions including a first direction from the surface ABCD side and a second direction from the surface EFGH side. Therefore, as shown in FIG. 6, the control unit 3 displays the arrow g indicating the measurement direction on the image display unit 2 together with the 3D image a generated by the 3D image generation unit 6 so that the user can select the measurement direction. To do. FIG. 6 shows an example when the first direction is selected. The control unit 3 distinguishes by displaying the measurement point measured from the first direction by ● and displaying the measurement point measured from the other direction by ○. In addition, below the 3D image a, design values and actual measurement values at the measurement points measured from the first direction are displayed in the form of Table h. The table h is shown to protrude from the image display unit 2, but this is for clearly showing the contents of the table h, and is displayed so as to fit in the image display unit 2 using a scroll function or the like. .

  When the second direction (plane EFGH side) is selected by the arrow g, the control unit 3 generates a 3D image j (generated by the 3D image generation unit 6) from the second direction as shown in FIG. The measurement points measured from the second direction are indicated by ●, and the measurement points measured from the other direction are indicated by ○. In addition, below the 3D image a, the design values and actual measurement values at the measurement points measured from the second direction are displayed in the form of Table k. The table k is displayed so as to be accommodated in the image display unit 2 using a scroll function or the like, similarly to the table h.

Note that the 3D image j may be rotated and displayed without changing the measurement direction using the arrow g, and the contents in the table may be changed as the 3D image j changes. Further, instead of switching and displaying FIGS. 6 and 7 for each measurement direction, FIGS. 6 and 7 may be displayed side by side in a list.
(3) Display in the case where measurements are performed on a plurality of samples When the measurement on a plurality of samples is performed on the same inspection object S due to reasons such as improvement in inspection accuracy, the control unit 3 displays in a comparable manner. For example, when three samples are measured for the point J, the control unit 3 displays the 3D image m generated by the 3D image generation unit 6 as shown in FIG. Is displayed with ●. In addition, below the 3D image m, information common to a plurality of samples such as the design value and tolerance of the inspection object S is displayed in the form of Table n, and individual information such as an actual measurement value and an error such as an error In the form of a table p.

Instead of displaying the measurement results for a plurality of samples in the form of a list, they may be switched and displayed by superimposing them in a sheet form.
(4) Display when adding information such as an annotation sentence As in the case of conventional handwritten inspection results, when adding information such as an annotation sentence, the control unit 3 displays an image. Information to be added to part 2 is displayed. The information to be added may be acquired together with the design value and the measured value in advance, or may be acquired based on a user operation via the operation unit 4 during display by the image display unit 2. For example, for the point J, when an annotation sentence “Attention to Δ △ of XX” has been acquired as information in advance, the control unit 3 displays a 3D image q as shown in FIG. This annotation text is displayed in the vicinity as a balloon r. Further, below the 3D image q, a design value or an actual measurement value at a measurement point, point J, is displayed in the form of a table t, and an annotation sentence similar to the balloon r is displayed in the table t.

  The control part 3 performs each display demonstrated by (1)-(4) above according to the shape of the to-be-inspected object S, and the content of measurement. Note that the techniques described in (1) to (4) may be combined. In addition to the methods described in (1) to (4), a user instruction for the displayed 3D image may be received, and the display content may be changed based on the received user instruction. For example, the measurement point may be selected by the user, and information (measured value or the like) at the measurement point selected by the user may be displayed in the form of a balloon. In addition, a condition (for example, “X = 0”, etc.) may be designated by the user, and the display content of the 3D image or table may be changed according to the condition.

  As described above, according to the present embodiment, the three-dimensional design value of the inspection object and the three-dimensional measurement values at a plurality of measurement points are acquired, and the 3D image of the inspection object is obtained based on the design value. Generate. Then, the generated 3D image and measurement values at a plurality of measurement points are displayed in association with each other, and reference points at the time of measurement at the plurality of measurement points are displayed based on the design value. Therefore, it is possible to create an easy-to-use inspection report in creating an inspection report using the three-dimensional design value of the inspection object and the three-dimensional measurement values at a plurality of measurement points. In particular, by displaying the reference points for measurement at a plurality of measurement points based on the design values, the reference can be clearly displayed even when the measurement reference points are not uniform.

  Moreover, according to this embodiment, the measured value by the measurement from several directions with respect to a to-be-inspected object is acquired, and these measured values are switched and displayed or displayed on a list. Therefore, when measurement is performed from multiple directions due to the shape of the object to be inspected, a single inspection report should be created, compared to the previous case where a plurality of inspection reports were created. It becomes possible, and usability improves in terms of management.

  In addition, according to the present embodiment, measurement values obtained by measuring a plurality of samples are acquired for the same inspection object, and the measurement values are switched and displayed or displayed in a list. Accordingly, when a plurality of samples are measured for the same inspection object due to reasons such as improvement in inspection accuracy, a plurality of inspection results documents are conventionally created. It is possible to create a single inspection report, which improves usability in terms of management.

  Further, according to the present embodiment, information related to the object to be inspected is acquired, and the acquired information is added and displayed on at least one of the 3D image and the measurement values at a plurality of measurement points. Therefore, it becomes possible to add information such as an annotation sentence in the same manner as a conventional handwritten inspection report, and usability is improved. In particular, by displaying information on at least one of a 3D image and measured values at a plurality of measurement points, a target location to which information is added, such as to which measurement point the information is added among the plurality of measurement points Can be clarified.

  Further, according to the present embodiment, a user instruction for the displayed 3D image is received, and the display content is changed based on the received user instruction. Therefore, the user can obtain desired information by giving an intuitive instruction while viewing the 3D image.
