3D object measurement from 2D images

Hello guys,

Im using this code to measure a 3D surface from 2D images (0r.png and 6rr.png), but i got an error and i still can't fix it. Can you guys check it, im a newbie in matlab.

>> im_analyze5_2

Index exceeds the number of array elements (9).

Error in im_analyze5_2 (line 51)

im(i).image = imread(strcat(im_dir , files(im_list(i)+2).name));
