mrpt::hwdrivers::CGyroKVHDSP3000 Class Referenceabstract

Detailed Description

A class for interfacing KVH DSP 3000 gyroscope with an assynchronous serial communication (product SN : 02-1222-01).

It uses a serial port connection to the device. The class implements the generic sensor class. See also the application "rawlog-grabber" for a ready-to-use application to gather data from the scanner. The generated observation is a CObservationIMU, but only the yaw angular velocity and the absolute yaw position are are set in the vector CObservationIMU::rawMeasurements. The sensor process rate is imposed by hardware at 100Hz. For now, this sensor is only supported on posix system.

PARAMETERS IN THE ".INI"-LIKE CONFIGURATION STRINGS:
-------------------------------------------------------
[supplied_section_name]
process_rate = 100 ; MUST be 100 Hz.
pose_x=0 ; Sensor 3D position relative to the robot (meters)
pose_y=0
pose_z=0
pose_yaw=0 ; Angles in degrees
pose_pitch=0
pose_roll=0
sensorLabel = <label> ; Label of the sensor
COM_port_LIN = /dev/ttyUSB0 ; COM PORT in LINUX
operatingMode = <"rate"/"integrated", "incremental"> ; Default mode is Rate.

In most of the communs applications, this class will be used as :

CConfigFile conf("conf.ini");
/// ...
kvh.loadConfig_sensorSpecific(conf, "KVH");
/// ...
while(1) {
kvh.doProcess();

void getObservations(TListObservations &lstObjects)
Returns a list of enqueued objects, emptying it (thread-safe).

◆ appendObservation()

void mrpt::hwdrivers::CGenericSensor::appendObservation ( const mrpt::utils::CSerializablePtr &  obj)

◆ appendObservations()

void mrpt::hwdrivers::CGenericSensor::appendObservations ( const std::vector< mrpt::utils::CSerializablePtr > &  obj)
protectedinherited

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

o-> .... // Set data
void appendObservation(const mrpt::utils::CSerializablePtr &obj)
Like appendObservations() but for just one observation.

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.
