Member Function Documentation

void firevision::VelocityGlobalFromRelative::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 firevision::VelocityModel.

coordsys_type_t firevision::VelocityGlobalFromRelative::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 )

Returns:: coordinate system type

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 )
