I'm toying with the idea of writing software to orthorectify images from different viewpoints and and extract 3D info from them. I know there IS such software, but I'd like to use only (free) open source stuff... Plus it's a great learning experience to try things for yourself :-)
The best component I found this far is OpenCV
, a software library for image processing. It has functions to transform images (e.g. for perspective), and has interesting articles and code for lens calibration / correction.
Here's the questions:
Has anybody experience with OpenCV?
Is there other good open source sw for photogrammetry?
Are there KAPers who are writing software to process their images?
