Has anyone had any issues with the ping sonar propagating error in such a way that the data graph takes on a sawtooth look?
The problem I’m having is that I will get an initially good read, but then the reported value will steadily increase (with a corresponding decrease in confidence) until it peaks and shoots back to the original close to correct value before repeating the cycle. It’s a little difficult to describe, hence the screenshot.
The test setup was a BlueROV2 on a table balanced (on the angles of the frame where the corners would be) looking down towards the floor, with speed of sound corrected to 343 m/s for bench accuracy testing. Actual distance to floor is 1.5~2m. FW is 3.26.
If you have any tips for me or need any info from me, please let me know. I’m new to using the ping sensor, so any help is appreciated.
Edit: I’m using this for obstacle avoidance so it’s forward mounted, not set up as an altimeter.
