Optical Distortion Calculation
Optical Distortion Calculation
(OP)
I am looking for a software implementation for the measurement of optical distortion in glass per ASTM C1652 for digital photography of grids.
My application is relatively large pieces of architectural glass, and the idea is that you take a photo of a grid without the glass then with the glass then measure the difference between them.
Are there any online open source or other libraries which might contain this? I don't mind paying for it.

RE: Optical Distortion Calculation
Tempered glass tends to have a sine wave shape with a wavelength of approx 10in and depth peak to trough of approx 0.004in. But there are other optical distortion sources too, like lamination and tool marks.
