(Operation)
The operation of the endoscope apparatus 1 will be described.

  FIG. 3 is a flow chart showing an example of measurement processing of the endoscope apparatus 1 according to the first embodiment of the present invention. FIG. 4 is a view showing an example of measurement points C1 and C2 in an endoscope image of the endoscope apparatus 1 according to the first embodiment of the present invention.

  In the example of the endoscopic image of FIG. 4, a turbine blade B, a cursor Cs, measurement points C1 and C2, a distance L between measurement points, a position information panel Pp, and indicators Dp1 and Dp2 are displayed.

  When the user inputs an instruction to start measurement processing using the instruction input unit, the control unit 51 reads the program of the measurement processing unit P1 from the memory 53, executes the program of the measurement processing unit P1, and performs measurement processing.

  The control unit 51 drives the imaging unit 12. On the imaging unit 12, two object images having parallax with each other are projected by the optical adapter 15. After performing various image processing, the control unit 51 outputs two subject images to the display unit 31 and displays an endoscope image based on the subject images on the display unit 31. FIG. 4 is a display example of an endoscopic image based on one subject image of two subject images. The control unit 51 may display an endoscope image based on one of the two subject images set in advance on the display unit 31.

  The control unit 51 arranges a cursor Cs that moves in response to an instruction input to the instruction input unit in the endoscopic image.

  The control unit 51 calculates the separation distance Z from the imaging unit 12 to the subject in the cursor Cs by calculation processing of triangular distance measurement using two subject images.

  The control unit 51 displays the coordinates of the cursor Cs (represented as "x, y" in FIG. 4), the separation distance Z, and the indicator Dp1 on the position information panel Pp.

  The indicator Dp1 indicates the separation distance Z by the number of rectangular patterns. For example, in the indicator Dp1, the number of rectangular patterns to be displayed increases according to the separation distance Z. In the example of FIG. 4, the indicator Dp1 is configured to be able to display up to three each of a green rectangular pattern, a yellow rectangular pattern and a red rectangular pattern, and among them, according to the separation distance Z, the green rectangular pattern and the yellow rectangular pattern Each of three is displayed, one red rectangular pattern is displayed, and two red rectangular patterns are hidden.

  The indicator Dp2 indicates the separation distance Z by the color of the rectangular pattern. For example, in the indicator Dp2, the rectangular pattern changes to green, yellow and red according to the separation distance Z. In the example of FIG. 4, the indicator Dp2 displays a red rectangular pattern.

  That is, the measurement processing unit P1 performs a predetermined operation on the separation distance Z from the imaging unit 12 to the subject at the measurement position based on the subject image having parallax so that the measurement region of the subject can be easily arranged at the measurement position. The calculated distance Z is displayed on the display unit 31.

  Subsequently, the first measurement process will be described. In the first measurement, measurement points C1 and C2 are set. The user moves the subject such that the subject is placed at a predetermined measurement position on the endoscopic image. For example, the user rotates and moves the turbine blade B with a turning tool (not shown) so that the turbine blade B is disposed at a predetermined measurement position. The user may move the imaging unit 12 by the bending unit 13 or an imaging unit moving mechanism (not shown). In addition, the user may move either the subject or the insertion unit 2 manually. Also, the user may set the measurement points C1 and C2 by coordinate input via the instruction input unit.

  The control unit 51 calculates the three-dimensional position of the measurement points C1 and C2 by a predetermined calculation, calculates the distance L between the measurement points, and displays the distance L on the display unit 31. Further, the control unit 51 writes the measurement points C1 and C2 to the file of the endoscopic image, and stores the file of the endoscopic image in a predetermined folder in the memory card C.

  That is, the measurement processing unit P1 calculates the distance between measurement positions which is the distance between a plurality of measurement positions by a predetermined calculation, and displays the distance between measurement positions on the display unit 31.

  When there are a plurality of subjects, such as when there are a plurality of turbine blades B, initial measurement processing is performed on all the subjects.

  Next, the second and subsequent measurements will be described.

  5-9 is a figure which shows the endoscopic image of the endoscope apparatus 1 concerning the 1st Embodiment of this invention. FIG. 5 shows an example of the measurement points C1 and C2, FIG. 6 shows an example of the predetermined search areas Sa1 and Sa2, and FIGS. 7 and 8 show an example of the partial enlarged image E.

  The previous measurement points C1 and C2 are read (S1). The control unit 51 reads the previously stored measurement points C1 and C2 from the memory card C.

  The measurement points C1 and C2 are displayed (S2). The control unit 51 displays the measurement points C1 and C2 acquired in S1 on the display unit 31.

  The measurement result is displayed (S3). The control unit 51 calculates the separation distance Z at the cursor Cs and calculates the distance L between measurement points by a predetermined calculation. The control unit 51 displays the cursor Cs, the separation distance Z, the indicators Dp1 and Dp2, and the distance L between measurement points on the display unit 31 as the measurement result. The user moves the subject based on the subject displayed on the display unit 31 and the measurement results of the indicators Dp1, Dp2 and the like so that the subject is disposed at a predetermined measurement position on the endoscopic image. The control unit 51 updates the measurement result displayed on the display unit 31 according to the movement of the subject.

  It is determined whether there is no problem in the measurement result (S4). The user visually observes the measurement result, and instructs and inputs whether or not there is a problem in the measurement result by the instruction input unit. When there is an instruction input indicating that there is no problem in the measurement result (S4: YES), the process proceeds to S9. On the other hand, when there is an instruction input indicating that there is a problem in the measurement result (S4: NO), the process proceeds to S5.

  For example, as shown in FIG. 4, when the measurement points C1 and C2 displayed in S2 overlap with the measurement position on the turbine blade B, the user inputs an instruction indicating that there is no problem in the measurement result. I do. On the other hand, as shown in FIG. 5, when there is damage Cr in the turbine blade B and the measurement point C2 is not overlapped with the measurement position on the turbine blade B, the user indicates that there is a problem in the measurement result Make an input.

  The predetermined search areas Sa1 and Sa2 are displayed (S5). The control unit 51 displays predetermined search areas Sa1 and Sa2 centered on each of the measurement points C1 and C2 on the endoscopic image.

  It is determined whether to change the predetermined search areas Sa1 and Sa2 (S6). The user visually checks the predetermined search areas Sa1 and Sa2 displayed in S5, and inputs an instruction by the instruction input unit whether to change the predetermined search areas Sa1 and Sa2. When there is an instruction input indicating that the predetermined search areas Sa1 and Sa2 are not changed (S6: NO), the process proceeds to S7. On the other hand, when there is an instruction input indicating that the predetermined search areas Sa1 and Sa2 are to be changed (S6: YES), the process proceeds to S6y.

  The predetermined search areas Sa1 and Sa2 are changed (S6 y). When the instruction input unit receives an instruction input for moving the measurement points C1 and C2, the control unit 51 changes the predetermined search areas Sa1 and Sa2 according to the instruction input. When the instruction input unit receives an instruction input, the control unit 51 enlarges or reduces the predetermined search areas Sa1 and Sa2. FIG. 7 is an example of a partially enlarged image E obtained by enlarging a predetermined search area Sa2. Note that the enlargement factor of the partial enlarged image E may be changed according to the operation of the instruction input unit such as the operation image Btn (the partial enlarged images E1, E2, and E3 in FIG. 8).

  Adjustment processing of the measurement point is performed (S7). The control unit 51 detects measurement point candidates C3 and C4 in the predetermined search areas Sa1 and Sa2. For example, as shown in FIG. 6, the control unit 51 extracts the contour of the subject from the endoscope image in the predetermined search areas Sa1 and Sa2, and sets feature points such as corners of the contour as measurement point candidates C3 and C4. Extract as Subsequently, the control unit 51 displays the measurement point candidates C3 and C4 on the endoscopic image. When the user inputs an instruction to select a measurement point candidate C3, the measurement point C2 is discarded and a measurement point C3 is newly set.

  That is, the measurement processing unit P1 sets a predetermined search area in the endoscopic image, detects a measurement position candidate in the predetermined search area, and displays the measurement position candidate on the display unit 31. In addition, the measurement processing unit P1 can display the partial enlarged image E of the endoscopic image including the measurement position, and the width of the predetermined search area changes in accordance with the enlargement ratio of the partial enlarged image E.

  The subject is measured (S8). The control unit 51 calculates the separation distance Z by a predetermined calculation based on the measurement points C1 and C3, calculates the distance L between the measurement points, and calculates the cursor Cs, the separation distance Z, the indicators Dp1 and Dp2, and the measurement points The distance L is displayed on the display unit 31.

  The inspection image and the measurement point are stored (S9). When an instruction is input from the user, the control unit 51 writes measurement points C1 and C3 which are measurement results in the endoscopic image, and stores the endoscopic image in a predetermined folder as an inspection image. In the example of FIG. 2, the control unit 51 stores an endoscope image named as “examination image 1” in “YYYYMMDD1 measurement” and “part 1”. When S9 ends, the process returns to S1 to perform measurement processing of the next subject. When the measurement process of all the objects is completed, the measurement process is completed.

  The processes of S1 to S9 constitute a measurement process according to the first embodiment.

  That is, in the measurement method, the subject is imaged by the imaging unit 12, the endoscope image acquired by acquiring the subject by the imaging unit 12 is displayed on the display unit 31, and the measurement position which is the position at which the object is measured is stored. Reading from the device, the measurement position on the endoscopic image is displayed on the display unit 31.

  Thereby, in the endoscope apparatus 1, setting of a measurement point can be performed simply.

  The subject is measured (S8). The control unit 51 calculates the distance L1 between measurement points by a predetermined calculation based on the measurement points C1 and C2. Subsequently, the control unit 51 calculates the distance L2 between measurement points by a predetermined calculation based on the measurement points C2 and C4. The control unit 51 sums up the distances L1 and L2 between measurement points to calculate the distance L between measurement points. The control unit 51 displays the cursor Cs, the separation distance Z, the indicators Dp1 and Dp2, and the distance L between measurement points on the display unit 31.

In the example of FIG. 13, the control unit 51 reads the measurement results of the measurement point C4 and the measurement point distance L4 corresponding to the damage Cr4, and the measurement point C5 and the measurement point distance L5 corresponding to the damage Cr5.

  The position of the measurement point candidate is calculated (S7 d). The control unit 51 calculates the position of the measurement point candidate C6 by a predetermined calculation. The measurement point candidate C6 is calculated by calculating the movement amount per unit time of the measurement point C5 from the measurement point C4 and multiplying the movement amount per unit time by the time from the measurement time of the measurement point C5 to the present time . The measurement point candidate C6 may be calculated by another calculation method.

  The measurement point candidate is displayed (S7e). As shown in FIG. 13, the control unit 51 displays the measurement point candidate C6.

  Set measurement points (S7f). When the user inputs an instruction to select the measurement point candidate C6, the control unit 51 sets the measurement point C6.

  The control unit 51 includes a reference data generation unit P6 (two-dot chain line in FIG. 1).

  The control unit 51 generates a measurement result file that is named according to the measurement result, and stores the measurement result file in a folder. In the example of FIG. 16, when there is no problem in the measurement result, the control unit 51 stores the measurement result in the folder by the file name with the identification character “OK”, such as “inspection image 1 OK” and “inspection image 2 OK” Do. On the other hand, when there is a problem in the measurement result, the control unit 51 stores the measurement result in the folder by the file name with the identification character “NG” as “inspection image 3 NG”.

  The control unit 51 generates reference data after the end of the previous inspection and before the start of the next inspection by the processing of the reference data generation unit P6. For example, as shown in FIG. 17, the control unit 51 copies the folder structure of “YYYYMMDD2 measurement” in which the previous measurement result is stored, and generates a “reference” folder. Subsequently, the control unit 51 extracts the file to which the identification character “NG” is attached from the “YYYYMMDD2 measurement” folder, and copies the file into the corresponding folder in the “reference” folder.

The reference data generation unit P6 generates reference data including the measurement position according to the subject and the measurement result stored in the storage device. With this, in the endoscope apparatus 1, from the inspection image in the “reference” folder, Measurement points can be read out.

  In the embodiment and the modification, when there is an instruction input indicating that there is no problem in the measurement result in S4 (S4: YES), the process proceeds to S9, and the inspection image is configured to be stored. However, when the inspection image having no problem is not stored, it may be configured to return from S4 to S1.

  Although the measurement result is stored in the memory card C in the embodiment and the modification, the measurement result stored in the memory card C may be stored in the server Sv via the information terminal Pc. In addition, the endoscope apparatus 1 may be connected to the server Sv via the network N by the external I / F 41, and read or write various information such as measurement results to the server Sv.

  In the embodiment and the modification, the storage device is the memory card C, but is not limited thereto. The storage device may be, for example, the memory 53, the information terminal Pc, the server Sv, or another external storage device.

  In the embodiment and the modification, an example in which the measurement position is the coordinate information of the measurement point has been described, but the coordinate information of the measurement line may be used. In this case, the measurement processing units P1 to P6 display the measurement line image at the measurement position on the endoscope image. For example, the measurement points C1 and C2 may be used as coordinate information of measurement lines, and a measurement line image CL (broken line in FIG. 4) connecting between the measurement points C1 and C2 may be displayed.

  In addition, the coordinate information of the measurement point may be corrected according to the zoom magnification of the endoscope image, and the measurement line may be reduced or enlarged, or after the measurement line is displayed, according to the movement of the endoscope image The coordinate information of the measurement point may be corrected, and the measurement line may be displayed following.

  The present invention is not limited to the above-described embodiment, and various changes, modifications, and the like can be made without departing from the scope of the present invention.
