ABSTRACT

In order to study lens focal length in detail, this paper uses image processing method to improve the research of lens focal length. The use of ruler, lens, lens to be measured and CCD to build an experimental system, the use of magnification method, the use of CCD to collect the lens to be measured focal plane image, using MATLAB digital image processing technology, through equalization, adding noise and other operations to measure the image height of the object, and then calculate the lens focal length size. The measurement of lens focal length is realized, and the feasibility of image processing in lens focal length measurement is verified.
