    Abstract

    The photo sensitive characteristic curve is one quality evaluating method of measuring film. Aiming at the strong subjectivity, big error, quantitative difficulty of the traditional evaluating method, the imaging quality evaluating method of optical measurement film was put forward, using Hough transform technology to make a space shift for the film photo sensitive characteristic curves, and evaluating the indexes of characteristics by analyzing and testing the changing rules, slope, broken-line rate of the characteristic curves. The experiment was done using two different imaging quality wedge films of 21 steps, the results prove the evaluating results are more correct and objective, it can truly reflect the imaging quality of the optical measurement film.
