Member Function Documentation

connect()

void Driver::connect	(	const std::string &	host,
		const unsigned int	base_port = 22222
	)

connect to qualisys server

Connect to qualisys server using the given host and base_port. Will throw if connection attempt is not successful.

Parameters

host	host of the qualisys server
base_port	the base port number of the server. This is not the actual port it is connecting to, as this is determined by the endianess of the connecting machine.

extractPacket()

int Driver::extractPacket ( uint8_t const *  buffer, size_t  size  ) const

protected

getBufferString()

std::string Driver::getBufferString ( )

protected

getTransform()

bool Driver::getTransform	(	base::Time &	time,
		base::Affine3d &	transform
	)

read a marker packet

Reads a marker packet and store the transformation for the given marker_idx in the given transform reference. The marker/body index is selected in the startStreamData call.

Parameters

time	[out] timestamp of the read packet
transform	[out] body to world transform of the given marker index

loadParameters()

void Driver::loadParameters

(

std::vector< std::string > &

labels

)

load marker configuration data from the server

loads the marker/body configuration data from the server, and fills the labels array with a list of found labels.

readQTMPacket()

bool Driver::readQTMPacket ( QTMHeader::EPacketType  type )

protected

readQTMString()

bool Driver::readQTMString ( std::string &  result )

protected

reads a packet from the stream and interprets it as a string

setQTMVersion()

bool Driver::setQTMVersion ( int  major, int  minor  )

protected

write a version command

startStreamData()

void Driver::startStreamData

(

const std::string &

label

)

start streaming marker data from the QTM Server

if connected, this will get the QTMServer to start streaming the processed marker data. The data can be read using the getTransform() method.

stopStreamData()

void Driver::stopStreamData

(

)

stop streaming of marker data

writeQTMCommand() [1/2]

void Driver::writeQTMCommand ( const std::string &  cmd )

protected

writeQTMCommand() [2/2]

void Driver::writeQTMCommand ( uint8_t const *  buffer, size_t  size  )

protected
