    how to find a best fitted curve from a group of curves (points)

    I am using a 2D laser scanner to scan a curved surface along it's longitude direction (y). This operation results in a point cloud in 3D space. At each y position, I can use least square to find a best fit curve in x,z axis, eg. a functin f(x). However, because of measurement noise, the...
