Geometric Distortion and Chromatic Displacement Tool
The MATLAB tool provided here is applicable for both ISO 17850:2015, Photography — Digital cameras — Geometric distortion (GD) measurements, and ISO 19084:2015, Photography — Digital cameras — Chromatic displacement measurements.
We appreciate your using these links. The cost is the same as purchasing the standards directly from ANSI and, by using the link, IS&T receives a commission that goes directly to support the ISO/TC 42 standards program.
ISO 17850:2015 specifies a protocol to measure geometric distortion of a digital camera. It is applicable to the measurement of digital cameras including camera phones. The MATLAB code provided here extracts the dots and finds the center of the dots as required in the Dot Chart method of ISO 17850:2015. (Click to go to the US ANSI website to purchase ISO 17850.)
ISO 19084:2015 specifies the definition of chromatic displacement for digital still cameras, test patterns, measurement conditions and methods, so as to enable the comparison of the results of measurement. The MATLAB code provided here extracts the dots and finds the center of the dots as required in the Dot Chart method of ISO 19084:2015. (Click to go to the US ANSI website to purchase ISO 19084.)
