mrpt::obs::CObservation3DRangeScan Class Reference

Detailed Description

A range or depth 3D scan measurement, as from a time-of-flight range camera or a structured-light depth RGBD sensor.

This kind of observations can carry one or more of these data fields:

• 3D point cloud (as float's).
• Each 3D point has its associated (u,v) pixel coordinates in points3D_idxs_x & points3D_idxs_y (New in MRPT 1.4.0)
• 2D range image (as a matrix): Each entry in the matrix "rangeImage(ROW,COLUMN)" contains a distance or a depth, depending on range_is_depth. Ranges are stored as uint16_t for efficiency. The units of ranges are stored separately in rangeUnits.
• 2D intensity (grayscale or RGB) image (as a mrpt::img::CImage): For SwissRanger cameras, a logarithmic A-law compression is used to convert the original 16bit intensity to a more standard 8bit graylevel.
• 2D confidence image (as a mrpt::img::CImage): For each pixel, a 0x00 and a 0xFF mean the lowest and highest confidence levels, respectively.
• Semantic labels: Stored as a matrix of bitfields, each bit having a user-defined meaning.
• For cameras supporting multiple returns per pixels, different layers of range images are available in the map rangeImageOtherLayers.

The coordinates of the 3D point cloud are in meters with respect to the depth camera origin of coordinates (in SwissRanger, the front face of the camera: a small offset ~1cm in front of the physical focal point), with the +X axis pointing forward, +Y pointing left-hand and +Z pointing up. By convention, a 3D point with its coordinates set to (0,0,0), will be considered as invalid. The field CObservation3DRangeScan::relativePoseIntensityWRTDepth describes the change of coordinates from the depth camera to the intensity (RGB or grayscale) camera. In a SwissRanger camera both cameras coincide, so this pose is just a rotation (0,0,0,-90deg,0,-90deg). But in Microsoft Kinect there is also an offset, as shown in this figure:

In any case, check the field relativePoseIntensityWRTDepth, or the method doDepthAndIntensityCamerasCoincide() to determine if both frames of reference coincide, since even for Kinect cameras both can coincide if the images have been rectified.

The 2D images and matrices are stored as common images, with an up->down rows order and left->right, as usual. Optionally, the intensity and confidence channels can be set to delayed-load images for off-rawlog storage so it saves memory by having loaded in memory just the needed images. See the methods load() and unload(). Due to the intensive storage requirements of this kind of observations, this observation is the only one in MRPT for which it's recommended to always call "load()" and "unload()" before and after using the observation, ONLY when the observation was read from a rawlog dataset, in order to make sure that all the externally stored data fields are loaded and ready in memory.

Classes that grab observations of this type are:

• mrpt::hwdrivers::CSwissRanger3DCamera
• mrpt::hwdrivers::CKinect
• mrpt::hwdrivers::COpenNI2Sensor

There are two sets of calibration parameters (see mrpt::vision::checkerBoardStereoCalibration() or the ready-to-use GUI program kinect-calibrate):

• cameraParams: Projection parameters of the depth camera.
• cameraParamsIntensity: Projection parameters of the intensity (gray-level or RGB) camera.

In some cameras, like SwissRanger, both are the same. It is possible in Kinect to rectify the range images such both cameras seem to coincide and then both sets of camera parameters will be identical.

Range data can be interpreted in two different ways depending on the 3D camera (this field is already set to the correct setting when grabbing observations from an mrpt::hwdrivers sensor):

• range_is_depth=true -> Kinect-like ranges: entries of rangeImage are distances along the +X (front-facing) axis.
• range_is_depth=false -> Ranges in rangeImage are actual distances in 3D.

The "intensity" channel may come from different channels in sesnsors as Kinect. Look at field intensityImageChannel to find out if the image was grabbed from the visible (RGB) or IR channels.

3D point clouds can be generated at any moment after grabbing with CObservation3DRangeScan::unprojectInto(), provided the correct calibration parameters. Note that unprojectInto() will store the point cloud in sensor-centric local coordinates. Use unprojectInto() to directly obtain vehicle or world coordinates.

Example of how to assign labels to pixels (for object segmentation, semantic information, etc.):

    // Assume obs of type CObservation3DRangeScan::Ptr
    obs->pixelLabels =TPixelLabelInfo::Ptr( new
*CObservation3DRangeScan::TPixelLabelInfo<NUM_BYTES>() );
    obs->pixelLabels->setSize(ROWS,COLS);
    obs->pixelLabels->setLabel(col,row, label_idx);   // label_idxs =
 [0,2^NUM_BYTES-1]
    //...

Note

Starting at serialization version 2 (MRPT 0.9.1+), the confidence channel is stored as an image instead of a matrix to optimize memory and disk space.

Starting at serialization version 3 (MRPT 0.9.1+), the 3D point cloud and the rangeImage can both be stored externally to save rawlog space.

Starting at serialization version 5 (MRPT 0.9.5+), the new field range_is_depth

Starting at serialization version 6 (MRPT 0.9.5+), the new field intensityImageChannel

Starting at serialization version 7 (MRPT 1.3.1+), new fields for semantic labeling

Since MRPT 1.5.0, external files format can be selected at runtime with CObservation3DRangeScan::EXTERNALS_AS_TEXT

Returns a deep copy (clone) of the object, indepently of its class.

Implements mrpt::rtti::CObject.

convertTo2DScan()

void CObservation3DRangeScan::convertTo2DScan	(	mrpt::obs::CObservation2DRangeScan &	out_scan2d,
		const T3DPointsTo2DScanParams &	scanParams,
		const TRangeImageFilterParams &	filterParams = TRangeImageFilterParams()
	)

Convert this 3D observation into an "equivalent 2D fake laser scan", with a configurable vertical FOV.

The result is a 2D laser scan with more "rays" (N) than columns has the 3D observation (W), exactly: N = W * oversampling_ratio. This oversampling is required since laser scans sample the space at evenly-separated angles, while a range camera follows a tangent-like distribution. By oversampling we make sure we don't leave "gaps" unseen by the virtual "2D laser".

All obstacles within a frustum are considered and the minimum distance is kept in each direction. The horizontal FOV of the frustum is automatically computed from the intrinsic parameters, but the vertical FOV must be provided by the user, and can be set to be assymetric which may be useful depending on the zone of interest where to look for obstacles.

All spatial transformations are riguorosly taken into account in this class, using the depth camera intrinsic calibration parameters.

The timestamp of the new object is copied from the 3D object. Obviously, a requisite for calling this method is the 3D observation having range data, i.e. hasRangeImage must be true. It's not needed to have RGB data nor the raw 3D point clouds for this method to work.

If scanParams.use_origin_sensor_pose is true, the points will be projected to 3D and then reprojected as seen from a different sensorPose at the vehicle frame origin. Otherwise (the default), the output 2D observation will share the sensorPose of the input 3D scan (using a more efficient algorithm that avoids trigonometric functions).

Parameters

[out]

out_scan2d

The resulting 2D equivalent scan.

inline

Unprojects the RGB+D image pair into a 3D point cloud (with color if the target map supports it) and optionally at a given 3D pose.

The 3D point coordinates are computed from the depth image (rangeImage) and the depth camera camera parameters (cameraParams). There exist two set of formulas for projecting the i'th point, depending on the value of "range_is_depth". In all formulas below, "rangeImage" is the matrix of ranges and the pixel coordinates are (r,c).

1) [range_is_depth=true] With "range equals depth" or "Kinect-like depth mode": the range values are in fact distances along the "+X" axis, not real 3D ranges (this is the way Kinect reports ranges):

x(i) = rangeImage(r,c) * rangeUnits
y(i) = (r_cx - c) * x(i) / r_fx
z(i) = (r_cy - r) * x(i) / r_fy

2) [range_is_depth=false] With "normal ranges": range means distance in 3D. This must be set when processing data from the SwissRange 3D camera, among others.

Ky = (r_cx - c)/r_fx
Kz = (r_cy - r)/r_fy

x(i) = rangeImage(r,c) * rangeUnits / sqrt( 1 + Ky^2 + Kz^2 )
y(i) = Ky * x(i)
z(i) = Kz * x(i)

The color of each point is determined by projecting the 3D local point into the RGB image using cameraParamsIntensity.

By default the local (sensor-centric) coordinates of points are directly stored into the local map, but if indicated so in takeIntoAccountSensorPoseOnRobot the points are transformed with sensorPose. Furthermore, if provided, those coordinates are transformed with robotPoseInTheWorld

Note

For multi-return sensors, only the layer specified in T3DPointsProjectionParams::layer will be unprojected.

relativePoseIntensityWRTDepth

mrpt::poses::CPose3D mrpt::obs::CObservation3DRangeScan::relativePoseIntensityWRTDepth

Initial value:

= {
        0, 0, 0, -90.0_deg, 0.0_deg, -90.0_deg}

Relative pose of the intensity camera wrt the depth camera (which is the coordinates origin for this observation).

In a SwissRanger camera, this will be (0,0,0,-90deg,0,-90deg) since both cameras coincide. In a Kinect, this will include a small lateral displacement and a rotation, according to the drawing on the top of this page.
