Correcting for lens distortion

johnnyC

Hello
Is there a method/function available in IPP that corrects for barrel distortion? I have images from which I need to take accurate measurements and need to take this lens effect into account.
Thanks
Johnny

Image-Pro Premier doesn't have a direct tool that corrects barrel distortion, but it has elastic deformation correction, which can be used to correct any distortion.

You can find it on the Process tab, Combine group - Image Compare - it will open you a new window where you can drop your original image and target image (you can create target image yourself and place a regular grid on it). Then you add registration Points to both Souce and Destination images that will define the distortion (you can add as many points as you need, could be 8-12 points).
Then use the Register button and choose "Thin Plate Spline" transformation method to create the corrected image.

Regards,

Yuri
