Abstract
Apparatus for taking spatial measurements from recorded radiographic or photographic films includes a co-ordinate measuring framework on which are statically mounted a video camera and light source, and on which can be placed the film. The camera scans a small area of the film which is illuminated by the light source and the film is movable beneath the camera to enable any part thereof to be scanned. The information produced by the camera is passed to a video-microdensitometer which displays on its output screen an image of the area of the film being scanned. Measurement is achieved by lining features on the displayed image against a datum line by movement of the film below the camera in the framework and noting the co-ordinates of the new positions of the film on the frameworks.
