Smoother position correlation for automotive vehicules

[Eric_S]

When geotagging pictures with a GNSS track, positions are linearly interpolated. I would like to have a smoother position interpolation when picture recording was done while driving a car. In tight turns, it doesn't look optimal (See attached picture). Indeed, the underlying physic of an automotive vehicle is associated with smoothness on position, speed and acceleration. Cubic spline seems to be well suited.

There are numerous trajectory generation solutions, based on the use of several mathematical models. Parametric Cubic Splines (De Boor (1978)) are used here, because they represent a
straightforward interpolation, they have a curvature continuity property, and they
are adapted to all road contexts (bend, straight line, roundabout, etc.).

So I would like a "automotive smoothness" option.
