Generic Camera
==============


**Base class for cameras in MORSE**


A generic camera class, which is expected to be used as a base class
for real camera. Concrete instantiation are currently:

    - :doc:`video_camera <../sensors/video_camera>`
    - :doc:`depth_camera <../sensors/depth_camera>`
    - :doc:`semantic_camera <../sensors/semantic_camera>`

.. note::
    The streaming of data from this sensor can be toggled off and on by
    pressing the SPACE key during the simulation. This will affect all the
    video cameras on the scene.

    Toggling off the cameras can help make the simulation run faster,
    specially when there are several cameras. However, the lack of
    data on the stream may cause problems to some middlewares.

You can set these properties in your scripts with ``<component>.properties(<property1>=..., <property2>=...)``.

- ``cam_width`` (default: ``256``)
	(no documentation available yet)
- ``cam_height`` (default: ``256``)
	(no documentation available yet)
- ``cam_focal`` (default: ``25.0``)
	(no documentation available yet)
- ``cam_near`` (default: ``0.1``)
	(no documentation available yet)
- ``cam_far`` (default: ``100.0``)
	(no documentation available yet)
- ``Vertical_Flip`` (default: ``False``)
	(no documentation available yet)
- ``retrieve_depth`` (default: ``False``)
	(no documentation available yet)
- ``retrieve_zbuffer`` (default: ``False``)
	(no documentation available yet)


.. cssclass:: fields morse-section

Data fields
-----------


This sensor exports these datafields at each simulation step:

- ``timestamp`` (float, initial value: ``0.0``)
	number of milliseconds in simulated time

*Interface support:*

(attention, no interface support!)

.. cssclass:: services morse-section

Services for Generic Camera
---------------------------

- ``get_properties()`` (blocking)
    Returns the properties of a component.
    
    
  - Return value

    a dictionary of the current component's properties  

- ``get_configurations()`` (blocking)
    Returns the configurations of a component (parsed from the properties).
    
    
  - Return value

    a dictionary of the current component's configurations  

- ``get_local_data()`` (blocking)
    Returns the current data stored in the sensor.
    
    
  - Return value

    a dictionary of the current sensor's data 



.. cssclass:: examples morse-section

Examples
--------


The following examples show how to use this component in a *Builder* script:

.. code-block:: python


    from morse.builder import *
    
    robot = ATRV()
    
    # creates a new instance of the sensor
    camera = Camera()

    # place your component at the correct location
    camera.translate(<x>, <y>, <z>)
    camera.rotate(<rx>, <ry>, <rz>)
    
    robot.append(camera)
    
    # define one or several communication interface, like 'socket'
    camera.add_interface(<interface>)

    env = Environment('empty')
