    Hi Götz, Thank you again for the reply. I had already considered using an XMP file to manually input alignment. The problem is that my design is modular and therefore not precisely located relative...

    Alignment of Thermal Cameras

    I am working on a scanner that combines thermal images with 3D scans (see this post) To align the thermal cameras, photograph a heated calibration board with holes. I use the hole location to try t...

    I have found the problem. For some reason RC had registered my thermal images in such a way that they still included some lens distortion parameters. I tracked them down, set all lens distortion pa...

    Thank you for the reply. I have implemented lens distortion removal techniques using OpenCV. Apart from the accuracy of the distortion removal its self there should be no distortion left in the the...

    I took them with different cameras at different positions, and used a calibration target in my scan. Then I defined control points based on those calibration images and saved camera alignment after...

    Thermal Texture Distorted

    I am trying to apply a thermal camera image as a texture on a 3D scan of a hand. I have aligned the camera using control points and am quite happy with the alignment.  For some reason it only appli...
