pfs-calibration is a set of command line tools for reconstructing an HDR image from a sequence of exposured. The software implements two photometric calibration methods: by Robertson et al. 2003 and by Mitsunaga and Nayar 1999. pfs-calibration is a part of pfstools (from version 2.0).

Here are some key features:

Tools provided with this software can be used for photometric calibration of both off-the-shelf digital cameras and HDR cameras as described in:

Photometric Calibration of High Dynamic Range Cameras

In: MPI Research Report MPI-I-2005-4-005.

Check a short tutorial on calibration of the LDR cameras and the recovery of the HDR images from multiple exposures. For details on the calibration of the HDR cameras please refer to the research report.

Please refer to the original pfscalibration web page for more information.
