The flight log contains the ultrasonic sensor height, only works up to around 10m but if you want to know the accurate height of each photo, you can take the photo, note the barometric height, then drop down until the ultrasonic sensors see the ground, subtract the new barometric height from the original and add on the ultrasonic sensor height. That should give you a photo height above ground level accurate to maybe 1 meter without having to land. If you have landing protection turned on then it is very quick to drop down to near ground level without hitting the ground. |
