Calibrated Fivepoint Solver

The code implements a calibrated fivepoints relative pose solver as described in the paper:

H. Stewénius, C. Engels, and D. Nistér. Recent developments on direct relative orientation. ISPRS Journal of Photogrammetry and Remote Sensing, 60:284-294, June 2006. [ bib | code | http | .pdf ]

Please cite this paper in work that uses the software.

The software consist of a matlab script and a mex-file. First compile the mex-file and then call one of the m-files.

  • calibrated_fivepoint.m
  • calibrated_fivepoint_helper.c
  • calibrated_fivepoint_non_gb.m, same functionality as above but implements the fivepoint method without computing a GB. Can be optimized to be extremely fast. (this code is written by Chris Engels).
