Vision-Based Industrial X-Ray Film Digitizing and Automatic Identification System

Abstract:

In this paper, a set of industrial X-ray film digitizing and automatic identification system is established with machine vision equipment. With this system, the industrial film can be digitalized rapidly and in high space resolution reaching to 860 DPI. The machine vision equipment includes linear CCD, light source, lens, aperture and film-moving machine. The controller is a master-slave mode, which includes a PC as the upper computer and an embedded system as the lower computer. The embedded system is composed by ARM and FPGA modules, which can control four axis motors and transmit an external trigger signals to the CCD in real-time. At last, a series of image processing algorithm is also developed in this paper to identify an industrial film that is captured to test coupling alignment of the casing pipes. The testing accuracy is 0.06mm.
