Mobile phone APP for interference fringe analysis

Abstract

The invention discloses a mobile phone APP for interference fringe analysis. The APP is composed of three man-machine interaction pages with functions of message pushing, fringe analysis and personalinformation and corresponding data processing parts. The main function of the APP is fringe analysis, wherein a user can shoot or select an interference fringe image, performs image cutting, specifiesa center axis, selects filtering frequency and selects fringe analysis items, and an analysis result is displayed on an APP result page. The interference fringe analysis process is carried out according to the setting of a user in a human-computer interaction process, including preprocessing, such as image filtering, binaryzation, and hole filling, applying an improved Zhang parallel rapid refinement algorithm to the binary image to perform skeleton extraction, enabling the skeleton to be subjected to burr and breakpoint processing, performing stripe level calibration, bright stripe number determination and central axis stripe spacing determination, applying a Zernike polynomial to perform surface shape fitting, calculating the PV value and the RMS value, and finally feeding back a processing result to the human-computer interaction part.

Description

technical field [0001] The invention relates to the field of mobile phone APP development and the field of image processing such as fringe thinning, fringe level calibration, surface shape fitting and reconstruction, etc., and specifically designs a mobile phone APP for interference fringe analysis. Background technique [0002] At present, most of the instruments for interference fringe analysis are large-scale devices connected behind the interferometer. Most of these devices image the interference fringes formed by the interferometer on CCD or CMOS, and then perform image processing on the computer to extract the interference fringe skeleton. , order calibration, etc. to fit the surface shape, interpret the PV value and RMS value of the current range plane, and finally display it on the computer monitor. Such devices are bulky, and most of them are integrated with interferometric instruments. They are not easy to operate and portable, and they are expensive, so they canno...
