Testing Images With Imatest
For an example of a macro lens test with this target, see Testing a macro lens using Checkerboard and Micro Multi-slide.
Using Imatest 4.5, the checkerboard region can be analyzed using the Checkerboard module. The dot pattern analysis module has been available since 2011 Release 3.8.
For older versions of Imatest, you can use the distortion module to calculate distortion from the checkerboard, but this is not as resistant to fisheye distortion as what is available with the Checkerboardmodule of Imatest 4.5.
