The /ardrone/navdata message should contains a field for estimated height called altd (see here), which I believe is from the ultrasound sensor on the drone.
In general it is difficult to estimate position from an IMU, as you need to dead reckon over the acceleration values to estimate height, and this process accumulates error.
There is a branch of research called visual inertial navigation in which the visual estimation is fused with IMU measurement to get metric distance and speed.
