Calculating a 3D Mean-Trajectory from an Array
11 views (last 30 days)
I have a big Matrix with XYZ entries. The data is from a lasertracker, that tracks a trajectory.
I now want to calculate a mean trajectory from 30 measured trajectories. Is this possible?
My thinking was:
- Split the matrix in the 30 submatrices (condition: when a point is close enough to the start/endpoint of the trajectory)
- Create a Trajectory from each submatrix
- Calculate the Mean Trajectory by adding the Values together and dividing by the number of trajectories
But how do I create a continous trajectory from a Matrix? I haven't found any solutions yet.
Thanks in Advance

You could interpolate the data to create a continuous trajectory from the set of points. You could use curve fitting toolbox for that.
Refer to the following link to generate a smooth 3d path with the 3D mean trajectory matrix.
