Title:
RADIOSCOPIC NON-DESTRUCTIVE INSPECTION METHOD AND RADIOSCOPIC NON-DESTRUCTIVE INSPECTION APPARATUS
Document Type and Number:
Japanese Patent JP2019090740
Kind Code:
A
Abstract:
To provide a radioscopic non-destructive inspection method and a radioscopic non-destructive inspection apparatus capable of estimating the size of an object to be inspected and the positional relationship (distance) between an X-ray source or the like and the object to be inspected from a magnified picked-up image when the position of a point source radiation source (focus) such as X-rays and the positional relationship between an image receiver and the object to be inspected are unknown.SOLUTION: A non-destructive inspection method of the present invention acquires two or more radioscopic images at respective positions by changing the positional relationship between a radiation source and an object to be irradiated, and geometrically calculates and estimates at least one of the size of an object to be inspected, the magnification of an image, and the distance between the radiation source and the object to be inspected, by using at least one measured data of the size or the diameter of the image on the picked-up image and the distance data between two positions of the radiation source and an image receiver.SELECTED DRAWING: Figure 1
