About the coordinates in the las files

[YamasakiRuna]

Hi, DBnet team!
In the las2fmap.py(line 30-33)
def lasReader(filename): """ Read xyz points from single las file :param filename: path of single point cloud """ f = File(filename, mode='r') x_max, x_min = np.max(f.x), np.min(f.x) y_max, y_min = np.max(f.y), np.min(f.y) z_max, z_min = np.max(f.z), np.min(f.z) return np.transpose(np.asarray([f.x, f.y, f.z])), \ [(x_min, x_max), (y_min, y_max), (z_min, z_max)], f.header
you use the "x y z" of the las file as the coordinate information.
But in the pointnet input script provide.py (line 142-143)
infile = laspy.file.File(self.X_train2[i]) data = np.vstack([infile.X, infile.Y, infile.Z]).transpose()
you use the "X Y Z" of the las file as the coordinate information.

Could you tell me the different between "x y z" & "X Y Z" because the number of them are not the same ("x y z"<200 and "X Y Z" are around 10^9)

Thanks!
