Point Cloud Coordinate

Hi,

I am trying to read the point cloud in the Matlab. However, after exporting the point cloud into .ply format from PIX4D and open it in Matlab, the coordinate of the point cloud is shown in a different coordinate system. As can be seen below, the x,y and z values of the point cloud are actually set around a certain central point of the point cloud. Is there any way that the point cloud (.ply) exported from PIX4D contained its original world coordinate?

 

Cheers,

Frank
