ABSTRACT:
A method and apparatus for locating the position of parts, and identifying hanges in parts position over time, within a radioactive cell by utilizing two cameras mounted on a stationary positioning table within the cell, each of the cameras being capable of relative displacement on the table under control of a computer, and each camera having a high resolution objective field smaller than the total desired viewing field. The method is implemented by simultaneously photographing the objective fields of both cameras, displacing one camera a predetermined distance relative to the other camera and repeating the step of simultaneously photographing, and repeating the displacement and simultaneous photographing steps over the entire viewing field; the method steps are repeated at a later time and a comparison is made of the viewing field images reproduced at the two times to identify relative changes in parts position with high resolution.
