Detailed Description

RGBDToPointCloudSensor_nws_ros: A Network grabber for kinect-like devices. This device will produce one stream of data for the point cloud derived fron the combination of the data derived from Framegrabber and IDepthSensor interfaces. See they documentation for more details about each interface.

Description of input parameters

Parameters required by this device are:

Parameter name SubParameter Type Units Default Value Required Description Notes
period - double s 0.033 No refresh period of the broadcasted values in s default 0.033 s
subdevice - string - - alternative to 'attach' action name of the subdevice to use as a data source when used, parameters for the subdevice must be provided as well
topic_name - string - Yes set the name for ROS point cloud topic must start with a leading '/'

Member Function Documentation

◆ attach()

bool RGBDToPointCloudSensor_nws_ros::attach ( yarp::dev::PolyDriver poly)
overridevirtual

Specify which sensor this thread has to read from.

Implements yarp::dev::IWrapper.

Definition at line 170 of file RGBDToPointCloudSensor_nws_ros.cpp.

◆ close()

bool RGBDToPointCloudSensor_nws_ros::close ( )
overridevirtual

Close the DeviceDriver.

Returns
true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 122 of file RGBDToPointCloudSensor_nws_ros.cpp.

◆ detach()

bool RGBDToPointCloudSensor_nws_ros::detach ( )
overridevirtual

WrapperSingle interface.

Implements yarp::dev::IWrapper.

Definition at line 154 of file RGBDToPointCloudSensor_nws_ros.cpp.

◆ fromConfig()

bool RGBDToPointCloudSensor_nws_ros::fromConfig ( yarp::os::Searchable params)

◆ open()

bool RGBDToPointCloudSensor_nws_ros::open ( yarp::os::Searchable params)
overridevirtual

Device driver interface.

Reimplemented from yarp::dev::DeviceDriver.

◆ operator=() [2/2]

RGBDToPointCloudSensor_nws_ros& RGBDToPointCloudSensor_nws_ros::operator= ( RGBDToPointCloudSensor_nws_ros &&  )
delete

◆ run()

void RGBDToPointCloudSensor_nws_ros::run ( )
overridevirtual

Loop function.

This is the thread itself. The thread calls the run() function every <period> ms. At the end of each run, the thread will sleep the amounth of time required, taking into account the time spent inside the loop function. Example: requested period is 10ms, the run() function take 3ms to be executed, the thread will sleep for 7ms.

Note: after each run is completed, the thread will call a yield() in order to facilitate other threads to run.

Implements yarp::os::PeriodicThread.

Definition at line 304 of file RGBDToPointCloudSensor_nws_ros.cpp.

◆ threadInit()

bool RGBDToPointCloudSensor_nws_ros::threadInit ( )
overridevirtual

Initialization method.

The thread executes this function when it starts and before "run". This is a good place to perform initialization tasks that need to be done by the thread itself (device drivers initialization, memory allocation etc). If the function returns false the thread quits and never calls "run". The return value of threadInit() is notified to the class and passed as a parameter to afterStart(). Note that afterStart() is called by the same thread that is executing the "start" method.

Reimplemented from yarp::os::PeriodicThread.

Definition at line 190 of file RGBDToPointCloudSensor_nws_ros.cpp.

◆ threadRelease()

void RGBDToPointCloudSensor_nws_ros::threadRelease ( )
overridevirtual

Release method.

The thread executes this function once when it exits, after the last "run". This is a good place to release resources that were initialized in threadInit() (release memory, and device driver resources).

Reimplemented from yarp::os::PeriodicThread.
