class mrpt::obs::CObservationRawDAQ

Store raw data from a Data Acquisition (DAQ) device, such that input or output analog and digital channels, counters from encoders, etc.

at one sampling instant. All analog values are assumed to be volts. On timing:

• CObservation::timestamp corresponds to the time of the first samples in each of the vectors.

• CObservationRawDAQ::sample_rate is the sampling rate, in samples per second per channel, as stored by the source driver.

Methods

virtual void getSensorPose(mrpt::poses::CPose3D&) const

Not used in this class.

virtual void setSensorPose(const mrpt::poses::CPose3D&)

Not used in this class.

virtual void getDescriptionAsText(std::ostream& o) const

Build a detailed, multi-line textual description of the observation contents and dump it to the output stream.

If overried by derived classes, call base CObservation::getDescriptionAsText() first to show common information.
