18 August 2011 3D information extraction based on a novel x ray imaging system
Author Affiliations +
In this paper, a novel x-ray imaging system was introduced. It was a CCD based system, but different from the traditional CCD based x-ray imaging system, which was composed of the x-ray intensifying screen, the CCD and the low light level image intensifier, specially using the zoom lens for coupling. Zoom lens can give a continuous variable visual field, which not only reduce the geometrical blur but also can produce several image pairs for stereo imaging. It is convenient for three dimension information extraction from a group of two dimension x-ray images and is valuable for stereovision radiography in the application of medical diagnosis, security checking, non-destructive testing, and industry detection. This stereo imaging method is also referential for the three dimension reconstruction daily living.
