For non-destructive testing of objects, an inexpensive 2D X-ray scanner has been created at the E.O. Paton Electric Welding Institute of the NAS of Ukraine, which is based on a digital mini sensor. Scan ning with such a sensor allows multiplying the working testing area. The fragments of digital X-ray images obtained during scanning are stitched into a full-format digital image by software. Image stitching algorithms are being studied, which allow increasing the scanning accuracy to 20 microns. This scanning accuracy is much higher than that of a scanner with an electromechanical drive. 6 Ref., 7 Fig.
Keywords: non-destructive testing, stitching images, X-ray digital imaging, portable 2D X-ray scanner
