center of curvature in one point of a curve

Hi everybody

I have a question about the center of curvature, I have a curve (a trajectory of a vehicule) I don't have a precise function of this curve I just have some points, and I want to know the center of curvature in one point in the trajectory,I calculate the curvature but I didn't know how to obtain the center of the curvature in one point. Please help me if you know the answer.

Do you mean the center of a circle which touchs the curve smoothly?

The radius of this circle is defined by the 2nd derivative, while the direction of the vector from the point to the center is the gradient.
