I have just downloaded the Octave (and MATLAB too) compatible version of the Multi-Camera Self-Calibration toolbox. It has a built in check and a section in the readme file, which says what are the expected values when that check is run.
The following command line is what starts the built-in check:
octave gocal.m --config=../strawlab/test-data/DATA20100906_134124/no-global-iterations.cfg
From the readme there is a section which tells what are the supposed results from running that check, and what are the final results.
My problem is that I'm getting slightly different values, compared the the ones mentions in the readme. Is it possible that I'm getting these differences (like 0.62 vs. 0.70 for the pixel errors) because I'm using a win32 build of Octave, and not a native linux version?
My other and more important question is that how could I run this script (gocal.m) from MATLAB? This script has a part, which takes the configuration file name from the command line argument --config=. No matter how I try to run this script from MATLAB, it always tells me that something is missing from argv.
The code is the following:
function [config] = read_configuration(filename)
if nargin == 0
% No argument given -- look for --config= on the command-line.
found_cfg = 0;
for cmdline_arg = argv()
arg = cmdline_arg{1}
szarg = size(arg);
if szarg(2) >= 10
if strcmp(arg(1:9), '--config=')
found_cfg = 1;
filename = arg(10:size(arg,2));
end
end
end
if ~found_cfg
error('missing --config=FILENAME command-line argument');
end
end
Can you tell me a way of how to pass on a given data for argv() and start the needed script with the --config= option?
- from within the MATLAB GUI, with run gocal ...
- from command line, with matlab -r gocal ...?
