I’m trying to solve for the “curvature” of a road, and wondering if this can be done with a standard mobile phone.
If I have a mobile phone fixed onto my vehicles windscreen, using only standard mobile phone sensors (accelerometer/gyro) and NO GPS, is it possible to determine the “curvature” of the road that the car is travelling on?! If so, how?
My current thought process is that I could use the combined readings from a gyro (ω) and accelerometer (a) and solve for R (Radius of curve) as below:
R = a/ω²
As R tends to infinity the road has no curvature (straight)
