easyidp.metashape.apply_transform_matrix

easyidp.metashape.apply_transform_matrix(points_xyz, matrix)

Transforms a point or points in homogeneous coordinates. equal to Metashape.Matrix.mulp() or Metashape.Matrix.mulv()

Parameters:

• matrix (np.ndarray) – 4x4 transform numpy array

• points_df (np.ndarray) –

  For example:

  # 1x3 single point
  >>> np.array([1,2,3])
     x  y  z
  0  1  2  3
  
  # nx3 points
  >>> np.array([[1,2,3], [4,5,6], ...])
     x  y  z
  0  1  2  3
  1  4  5  6
  ...
  

Returns:

out – same size as input points_np:

   x  y  z
0  1  2  3
1  4  5  6

Return type:

pd.DataFrame
