Description of the Related Art In ultrasonic flaw detection tests, in order to analyze flaw detection results, identify the position of a reflection source, and visualize flaw detection results, ultrasonic probe position data (movement amount from a reference point) is used. ) Is required. Further, as for the head swing scanning of the probe, it is mainly used in manual flaw detection, but it is difficult to quantitatively detect the head swing amount by the conventional flaw detection method.

【発明が解決しようとする課題】超音波探触子の位置を

触子をセンサから分離した（すなわち、外部センサを利
用する）検出方法とがある。One of the methods of detecting the position of the ultrasonic probe is a method of directly measuring using a scale (a ruler) or the like. This is a method mainly used in a manual flaw detection test, and has problems in efficiency, accuracy, reproducibility, etc. of the test. Further, as a method of detecting using a sensor, there are a detection method in which a probe and a detection sensor are integrated, and a detection method in which the probe is separated from the sensor (that is, an external sensor is used).

（２）試験体表面にバーコードを付着し、バーコードの
センサで移動量を検出する方式がある。The former integrated detection method is as follows: (1) A probe is incorporated into a computer mouse similar to that of a computer, and a sphere in the mouse comes into contact with a test body, and the sphere rotates when the probe moves. There is a method. The amount of rotation of this sphere is detected by two encoders that are in contact with the sphere, and the amount of movement in the vertical and horizontal directions is detected. This integrated detection method also includes:
(2) There is a method in which a barcode is attached to the surface of the test body and the amount of movement is detected by a barcode sensor.
【０００５】しかし、この一体型検出方法においける

振り量を検出できない。However, in the method (1) in the integrated detection method, when there is a contact medium, the contact medium is present at the contact portion between the test body and the mouse sphere or the contact portion between the mouse sphere and the encoder. , The friction coefficient decreases, the ball slips, and the amount of movement cannot be detected. Further, in the method (2), if a bar code is present on the surface of the test piece, the surface condition changes, which affects the flaw detection test result, so that the part to which the bar code is attached cannot be tested. Further, since it is necessary to attach the barcode to the surface of the test body, it cannot be applied to any place other than the place where the barcode is attached.
Due to the characteristics of barcodes, only one-dimensional movement can be measured. Neither of the above methods (1) and (2) can detect the head swing amount of the probe.

(1) A method in which the probe is externally controlled and scanned, and a sensor for detecting the movement amount is also arranged outside (mainly automatic flaw detection). The amount of movement of the probe is indirectly measured. (2) A method of manually measuring the position of the probe with a scale. (3) A method in which the probe is provided with a mark such as an LED, and the position of the probe is calculated based on the principle of triangulation with a plurality of cameras arranged outside to detect the movement amount. (4) A method of measuring the position of the probe using the same principle as in (3) using sound waves. (5) A method of detecting the amount of movement of the probe by using two wire type encoders (JP-A-9-274024).

Therefore, it is an object of the present invention to provide a method and apparatus for measuring the relative position (or movement amount) of the probe and the swing amount of the probe without contacting the test body.
