Fast Altitude Calculation

I need to quickly measure altitude between 0 and 10M with a downward facing ZED2 camera. The barometer sensor publishes at 24Hz and depth measurement is about the same it seems when using the center pixel demo. Any suggestions on obtaining altitude (or depth) measurements as fast as possible?

Hi @PureRockets
have you tried using the VGA resolution at 100 FPS?

Great suggestion, I have not. Also, I believe I can also use the IMU data in addition to the barometer data to get an accurate interpolation.

If the motion is constantly accelerated (no uniform speed) you can get a good estimation using the IMU since it moves only along one axis
