selfcalib.m

[maxim.t...@gmail.com]

Hello, I find these approach and he is a very interesting.
I try to run selfcalib function on Matlab.

size(Ws)
12   563
size(IdMat)
4   563
selfcalib(Ws,IdMat)

But I receive error:

Error in ==> selfcalib
Ws(i*3-2:i*3-1,IdMat(i,:)>0) = [X_i'; ones(1,sum(IdMat(i,:)>0))];

I try understand.
So size of left and right parts are different

size(Ws(i*3-2:i*3-1,IdMat(i,:)>0))
ans =
     2   474
size([X_i'; ones(1,sum(IdMat(i,:)>0))])
ans =
     3   474

I want run code and after that understand how it works step by step.
Where Is error. How it fix.
Or maybe I use this code in wrong way.

Thanks!

Perhaps you could try using the MATLAB Debugger? http://www.mathworks.com/help/matlab/matlab_prog/debugging-process-and-features.html

Best,

Thanks, for your answer.
With the debugger is much easier to test code.
Anyway, I try to replace

Ws(i*3-2:i*3-1,IdMat(i,:)>0) = [X_i'; ones(1,sum(IdMat(i,:)>0))];

by code:

Ws(i*3-2:i*3-1,IdMat(i,:)>0) = [X_i'];

I think this part (with one's ) convert data to homogeneous coordinate.

On this line, there is no error, but there is another.

Lambda_est = estimateLambda(Ws,IdMat);

on line

F_ij = pair(i).F;

??? Improper index matrix reference.

Error in ==> estimateLambda at 38
  F_ij = pair(i).F;

where

function [Lambda] = estimateLambda(Ws,pair)

so its strange. What is it .F ? for IdMat
