Embodiment Construction
[0030] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.
[0031] The optical equal thickness interference image data processing system includes the following steps:
[0032] Step 1, image capture.
[0033] To digitize the equal-thickness interference pattern, it is the key to obtain a clear image of Newton's ring interference. Therefore, a height-adjustable CCD imaging system is loaded on the eyepiece of the reading microscope to capture a high-definition Newton's ring interference image.
[0034] Step 2, enhance the contrast.
[0035] The commonly used histogram equalization enhancement algorithm is adopted.
[0036] Step 3, grayscale.
[0037] For the image with enhanced contrast, further grayscale processing is required to make the three values of G, R, and B of the image equal, which are all equal to the grayscale value; the grayscale is performed by the weighting method, and set g ...

The invention proposes a light equal thickness interference image data processing system, which first collects a clear Newton ring image with a CCD camera, and then performs grayscale, binarization, and refinement processing on the image to effectively improve the image quality. Then take three pixels on the interference ring to measure the radius of the ring. Finally, the radius of curvature of the plano-convex lens is calculated by substituting the formula for calculating the radius of curvature. Compared with the prior art, the invention has the advantages of simple reading, short measurement time, no visual fatigue of the user, and large measurement error of the traditional manual reading method, while the measurement error of the present invention is small, which solves the inconvenience of the current manual reading. The problem of continuous observation and storage of image information for a long time.
