Abstract (en)

[origin: WO2014012946A1] There is disclosed a method, arrangement and computer program product for correcting distortion present in an image captured using an infrared (IR) arrangement, the method for an embodiment comprising: capturing a first image using a first imaging system comprised in said IR arrangement; and correcting image distortion of the first image based on a pre-determined distortion relationship. According to embodiments, the method may further comprise capturing a second image using a second imaging system comprised in said IR arrangement, wherein: said distortion relationship represents distortion caused by said first and/or second imaging systems of said IR arrangement; and said correcting of image distortion of the first image comprises correcting image distortion with relation to the second image based on said pre-determined distortion relationship, wherein the distortion relationship represents distortion caused by said first and/or second imaging systems.
