Input/Output

• input cam. Input a set of calibration files referenced by the Calib Filename text string (eg calib_file). There are three files that will be searched for and read if present.

  calib_file.l.cam  :  Full left camera parameter description.
  calib_file.r.cam  :  Full right camera parameter description.
  calib_file.s.cam  :  Stereo transformation and free parameter
                       covariances.
  

  In addition the inputted files are duplicated in

  calib_file_save.l.cam
  calib_file_save.r.cam
  calib_file_save.s.cam
  

  in order to prevent accidental loss.

• output cam. Output the calibration files specified by the Calib Filename text string.

• store geom. save a file of matched image coordinates (left and right) and associated 3D data (seven numbers per data point left image x,y, right image x,y, and 3D x,y,z) to the file specified by the Base Filename text string (eg calib_grid). The file is appended with ".cor".

• restore geom. read a saved data file specified by the Base Filename text string. The data is filtered on reading to check for consistency with the current data model. Data points are removed if both cameras have a reprojection error greater that the parameter "accuracy". This facility is mainly used for iteratively removing outliers from the calibration data during the calibration process.
