Constructor & Destructor Documentation

pcl::DepthSenseGrabber::DepthSenseGrabber ( const std::string &  device_id = "")

Create a grabber for a DepthSense device.

The grabber "captures" the device, making it impossible for other grabbers to interact with it. The device is "released" when the grabber is destructed.

This will throw pcl::IOException if there are no free devices that match the supplied device_id.

[in]device_iddevice identifier, which might be a serial number, an index (with '#' prefix), or an empty string (to select the first available device)

Member Function Documentation

void pcl::DepthSenseGrabber::disableTemporalFiltering ( )

Disable temporal filtering.

void pcl::DepthSenseGrabber::enableTemporalFiltering ( TemporalFilteringType  type,
size_t  window_size = 1 

Enable temporal filtering of the depth data received from the device.

The window size parameter is not relevant for DepthSense_None filtering type.

std::string pcl::DepthSenseGrabber::getDeviceSerialNumber ( ) const

Get the serial number of device captured by the grabber.

virtual float pcl::DepthSenseGrabber::getFramesPerSecond ( ) const

returns fps.

0 if trigger based.

Implements pcl::Grabber.

virtual std::string pcl::DepthSenseGrabber::getName ( ) const

returns the name of the concrete subclass.

the name of the concrete driver.

Implements pcl::Grabber.

Definition at line 109 of file depth_sense_grabber.h.

virtual bool pcl::DepthSenseGrabber::isRunning ( ) const

Indicates whether the grabber is streaming or not.

This value is not defined for triggered devices.

true if grabber is running / streaming. False otherwise.

Implements pcl::Grabber.

void pcl::DepthSenseGrabber::setConfidenceThreshold ( int  threshold)

Set the confidence threshold for depth data.

Each pixel in a depth image output by the device has an associated confidence value. The higher this value is, the more reliable the datum is.

The depth pixels (and their associated 3D points) are filtered based on the confidence value. Those that are below the threshold are discarded (i.e. their coordinates are set to NaN).

virtual void pcl::DepthSenseGrabber::start ( )

For devices that are streaming, the streams are started by calling this method.

Trigger-based devices, just trigger the device once for each call of start.

Implements pcl::Grabber.

virtual void pcl::DepthSenseGrabber::stop ( )

For devices that are streaming, the streams are stopped.

This method has no effect for triggered devices.

Implements pcl::Grabber.
