Single pixel distortion correction

[slawek sobotka]

Hi, we are dealing with image processing that is focused on finding "holes". I need speed so I need to correct distortion of only one pixel instead of whole picture.

We can do some calibration at the beginning of the process.

So my question is: is there any algebraic formula for one pixel or maybe source code at the guts of BoofCV that can correct single point?

Lens distortion right? BoofCV does undistort on contours for speed throughout its codebase. Here's an abstract way to compute the transform. In this case it's converting it from pixels to pixels. You could use normalized image coordinates too.

LensDistortionNarrowFOV narrow = LensDistortionFactory.narrow(intrinsics);
Point2Transform2_F32 undistortPixelToPixel = narrow.undistort_F32(/* input pixel */ true, /* output pixels */ true);
undistortPixelToPixel.compute(distorted.x, distorty.y, undistorted);
