.. _reconstruction_system_integrate_scene:
Integrate scene
-------------------------------------
The final step of the system is to integrate all RGBD images into a single TSDF
volume and extract a mesh as the result.
Input arguments
``````````````````````````````````````
The script runs with ``python run_system.py [config] --integrate``. In
``[config]``, ``["path_dataset"]`` should have subfolders *image* and *depth*
in which frames are synchronized and aligned. In ``[config]``, the optional
argument ``["path_intrinsic"]`` specifies path to a json file that has a camera
intrinsic matrix (See :ref:`/tutorial/pipelines/rgbd_odometry.ipynb#read-camera-intrinsic` for
details). If it is not given, the PrimeSense factory setting is used instead.
Integrate RGBD frames
``````````````````````````````````````
.. literalinclude:: ../../../examples/python/reconstruction_system/integrate_scene.py
:language: python
:pyobject: scalable_integrate_rgb_frames
:end-at: o3d.visualization.draw_geometries([mesh])
:linenos:
:lineno-match:
This function first reads the alignment results from both
:ref:`reconstruction_system_make_fragments` and
:ref:`reconstruction_system_register_fragments`, then computes the pose of each
RGBD image in the global space. After that, RGBD images are integrated using
:ref:`/tutorial/pipelines/rgbd_integration.ipynb`.
Results
``````````````````````````````````````
This is a printed log from the volume integration script.
.. code-block:: sh

Fragment 000 / 013 :: integrate rgbd frame 1 (2 of 100).

Fragment 000 / 013 :: integrate rgbd frame 3 (4 of 100).
