Member Function Documentation

void VelocityFromGlobal::calc (  )  [virtual]

Calculate velocity values from given data This method must be called after all relevent data (set*) has been set.

After calc() the velocity values can be retrieved

Implements VelocityModel.

Definition at line 155 of file globvelo.cpp.

References GlobalPositionModel::get_x(), and GlobalPositionModel::get_y().

coordsys_type_t VelocityFromGlobal::getCoordinateSystem (  )  [virtual]

Returns the used coordinate system, must be either COORDSYS_ROBOT_CART or COORDSYS_ROBOT_WORLD.

ROBOT denotes velocities relative to the robot (which can be tramsformed to global velocities by: glob_vel_x = rel_vel_x * cos( robot_ori ) - rel_vel_y * sin( robot_ori ) WORLD denotes velocities in the robot coordinate system glob_vel_y = rel_vel_x * sin( robot_ori ) + rel_vel_y * cos( robot_ori )

Implements VelocityModel.

Definition at line 222 of file globvelo.cpp.

const char * VelocityFromGlobal::getName ( void   )  const [virtual]

Get name of velocity model.

Returns:
name of velocity model

Implements VelocityModel.

Definition at line 215 of file globvelo.cpp.

void VelocityFromGlobal::getTime ( long int *  sec,
long int *  usec 
) [virtual]

Get time from velocity.

Parameters:
sec contains seconds since the epoch upon return (Unix timestamp)
usec contains microseconds upon return

Implements VelocityModel.

Definition at line 120 of file globvelo.cpp.

void VelocityFromGlobal::getVelocity ( float *  vel_x,
float *  vel_y 
) [virtual]

Method to retrieve velocity information.

Parameters:
vel_x If not NULL contains velocity in X direction after call
vel_y If not NULL contains velocity in Y direction after call

Implements VelocityModel.

Definition at line 128 of file globvelo.cpp.
