Using Elmer for simulation of ultrasonic tomography system
Posted: 29 Jun 2019, 22:49
Hello,
I have a question and hope that you can help me.
We are trying to get into using automotive ultrasonic sensors for 3d environment mapping.
The idea is similar to medical 3d ultrasonic devices or how bats map the environment.
You send pulsed ultrasonic waves into different directions (the bat moves the head, we use
some sensors with well defined locations). Then sensors are taking turns, sending,
waiting for the echo, then the next one.
After a full iteration through all sensors it is possible to estimate a 3d map of the environment.
But how good this works is depending strongly on the location of the sensors, their orientation
and of course how many sensors are being used.
Thus we would like to get into some theory first. Since I used Elmer for other projects
I thought it might be possible to use it to simulate a use case (cars on a street, some houses along
the road, maybe some pedestrians).
Do you think it is possible? Pulsed waves? Which model could be used?
Kind regards,
Markus
