Detailed Description

A class for grabing "range images", intensity images (either RGB or IR) and other information from an Xbox Kinect sensor.

To use Kinect for Windows or ASUS/Primesense RGBD cameras, use the class COpenNI2.

Configuration and usage:

Data is returned as observations of type mrpt::obs::CObservation3DRangeScan (and mrpt::obs::CObservationIMU for accelerometers data). See those classes for documentation on their fields.

As with any other CGenericSensor class, the normal sequence of methods to be called is:

CGenericSensor::loadConfig() - Or calls to the individual setXXX() to configure the sensor parameters.
CKinect::initialize() - to start the communication with the sensor.
call CKinect::getNextObservation() for getting the data.

Calibration parameters

For an accurate transformation of depth images to 3D points, you'll have to calibrate your Kinect, and supply the following threee pieces of information (default calibration data will be used otherwise, but they'll be not optimal for all sensors!):

Camera parameters for the RGB camera. See CKinect::setCameraParamsIntensity()
Camera parameters for the depth camera. See CKinect::setCameraParamsDepth()
The 3D relative pose of the two cameras. See CKinect::setRelativePoseIntensityWrtDepth()

See http://www.mrpt.org/Kinect_calibration for a procedure to calibrate Kinect sensors with an interactive GUI program.

Coordinates convention

The origin of coordinates is the focal point of the depth camera, with the axes oriented as in the diagram shown in mrpt::obs::CObservation3DRangeScan. Notice in that picture that the RGB camera is assumed to have axes as usual in computer vision, which differ from those for the depth camera.

The X,Y,Z axes used to report the data from accelerometers coincide with those of the depth camera (e.g. the camera standing on a table would have an ACC_Z=-9.8m/s2).

Notice however that, for consistency with stereo cameras, when loading the calibration parameters from a configuration file, the left-to-right pose increment is expected as if both RGB & IR cameras had their +Z axes pointing forward, +X to the right, +Y downwards (just like it's the standard in stereo cameras and in computer vision literature). In other words: the pose stored in this class uses a different axes convention for the depth camera than in a stereo camera, so when a pose L2R is loaded from a calibration file it's actually converted like:

L2R(this class convention) = CPose3D(0,0,0,-90deg,0deg,-90deg) (+) L2R(in the config file)

Some general comments

Depth is grabbed in 10bit depth, and a range N it's converted to meters as: range(m) = 0.1236 * tan(N/2842.5 + 1.1863)
This sensor can be also used from within rawlog-grabber to grab datasets within a robot with more sensors.
There is no built-in threading support, so if you use this class manually (not with-in rawlog-grabber), the ideal would be to create a thread and continuously request data from that thread (see mrpt::system::createThread ).
The intensity channel default to the RGB images, but it can be changed with setVideoChannel() to read the IR camera images (useful for calibrating).
There is a built-in support for an optional preview of the data on a window, so you don't need to even worry on creating a window to show them.
This class relies on an embedded version of libfreenect (you do NOT need to install it in your system). Thanks guys for the great job!

Converting to 3D point cloud

You can convert the 3D observation into a 3D point cloud with this piece of code:

mrpt::obs::CObservation3DRangeScan  obs3D;
mrpt::maps::CColouredPointsMap       pntsMap;
pntsMap.colorScheme.scheme = CColouredPointsMap::cmFromIntensityImage;
pntsMap.loadFromRangeScan(obs3D);

Then the point cloud mrpt::maps::CColouredPointsMap can be converted into an OpenGL object for rendering with mrpt::maps::CMetricMap::getAs3DObject() or alternatively with:

mrpt::opengl::CPointCloudColouredPtr gl_points = mrpt::opengl::CPointCloudColoured::Create();

gl_points->loadFromPointsMap(&pntsMap);

Raw depth to range conversion

At construction, this class builds an internal array for converting raw 10 or 11bit depths into ranges in meters. Users can read that array or modify it (if you have a better calibration, for example) by calling CKinect::getRawDepth2RangeConversion(). If you replace it, remember to set the first and last entries (index 0 and KINECT_RANGES_TABLE_LEN-1) to zero, to indicate that those are invalid ranges.

R(d) = k3 * tan(d/k2 + k1);
k1 = 1.1863, k2 = 2842.5, k3 = 0.1236

Platform-specific comments

For more details, refer to libfreenect documentation:

Linux: You'll need root privileges to access Kinect. Or, install MRPT/scripts/51-kinect.rules in /etc/udev/rules.d/ to allow access to all users.
Windows:
- Since MRPT 0.9.4 you'll only need to install libusb-win32: download and extract the latest libusb-win32-bin-x.x.x.x.zip
- To install the drivers, read this: http://openkinect.org/wiki/Getting_Started#Windows
MacOS: (write me!)

◆ setVideoChannel()

void CKinect::setVideoChannel ( const TVideoChannel vch )
