We, the WAMI group, decided we should make a proper simulation toolkit in order to test our algorithms on a system as close to the reality as possible.
Tonight Issam and I worked on implementing the algorithm chosen to check wether or not it is working. Our first tests ran perfectly well.
For a given point we calculate the flying time of the ultrasound. When we transmit those arguments to our algorithm it manages to work out what the original point was with a very high precision. Thanks to this toolkit we will be able to study more precisely how the different parameters affect our results. For instance we hope to see how much deviation we get, if the speed of the ultrasound changes (it is very sensitive to the temperature and humidity).
Concerning the algorithm itself, we chose to have a very specific position of our transmitters (they are at the tips a a standard orthonormal basis) + one is at the origin of the basis.
This method seems very accurate. According to me the only drawback is that we need to have a very specific position of our transmitters ( we cannot randomly put them where we want). We are looking for a silution in order to improve this.
