A resolving power test method, device and computer readable storage medium

Abstract

The application discloses a kind of analytical force test method, equipment and computer readable storage medium, the method includes collecting the line pair image obtained by the camera module to be measured to test mark plate shooting, wherein test mark plate contains at least one mark plate unit, at least one line pair is provided on each mark plate unit;Line pair image is preprocessed, to locate and extract the imaging feature area of all corresponding mark plate units in line pair image;Each line pair in imaging feature area is independently polynomial fitted respectively, and the brightness-pixel position fitting function corresponding to each line pair is obtained;According to the brightness-pixel position fitting function corresponding to each line pair, the brightness peak value and brightness trough value of line pair are extracted, and the analytical force numerical value corresponding to each line pair is calculated.The analytical force test method of the application can realize multi-direction analytical force test and accurate evaluation of detail clarity, which helps to improve line pair detection precision.
