copied!<p>I'm trying out the <a href="http://code.google.com/p/osm-bundler/" rel="nofollow">OpenStreetMap bundler</a> program and I can't find details on the camera position data. The point cloud data is in a *.ply file that looks like this:</p> <pre><code>ply format ascii 1.0 element face 0 property list uchar int vertex_indices element vertex 1340 property float x property float y property float z property uchar diffuse_red property uchar diffuse_green property uchar diffuse_blue end_header -1.967914e-001 -8.918888e-001 -3.318706e+000 92 86 88 -1.745216e-001 -2.186521e-001 -3.227759e+000 50 33 31 -1.585826e-001 -1.894233e-001 -3.271651e+000 61 43 43 ... -2.649703e-003 2.197792e-002 3.906710e-002 0 255 0 -2.354721e-003 2.235805e-002 -1.093058e-002 255 255 0 5.296331e-003 4.755635e-001 -1.298959e+000 255 0 0 3.155302e-003 4.634443e-001 -1.347420e+000 255 255 0 1.910245e-003 2.891324e-001 -1.070228e-001 0 255 0 2.508708e-003 2.884968e-001 -1.570152e-001 255 255 0 -2.246127e-002 -6.257610e-001 9.884196e-001 255 0 0 -2.333330e-002 -6.187732e-001 9.389180e-001 255 255 0 </code></pre> <p>The last eight lines appear to be the positions for four cameras (from four images). One line is position, second line is orientation. The position colors are either green or red and the orientation is yellow.</p> <p>I can't find info on this so I'm wondering if this is correct and also what does red and green mean? Good/bad data? Any other info about using osm-bundler results is helpful.</p>
