Initiate session

The setup code assumes that the above libs have been placed in a common folder , below referred to as the library path.

For Unix/Linux:

1. Start matlab with ./start_matlab.sh <absolute library path>.
2. Run setup.m

Otherwise:

1. Run setup.m <absolute library path>

Running the example

The example is executed with reconstruct_corner.m and uses data from the folder corner. Settings for the reconstruction are found in corner/reconstr_setup.m.

1. cd SfM_lib
2. Run reconstruct_corner.m

Running on your images

1. Put your images in a folder together with your settings file named reconstr_setup.m. Copy the corner example settings file to use as a template.
2. Make sure the settings file points correctly to your calibration data.
3. Run reconstruct_scene <path to data>
