This is an extension for 3D Slicer that computes distance between two point sets or a point set and a surface mesh.
This module was developed to address research work at the Canterbury District Health Board, New Zealand. We would like to thank Andras Lasso (Queen's University) who made valuable contributions to the code and gave useful advice on developing a scripted module.
This module was primarily designed to compute distances from a low density point cloud of fiducial points to the surface of a model. Error metrics such as mean distance, root mean square distance, maximum distance and minimum distance are computed and displayed in a table
This module has also been extended to compute distances between two sets of point coulds made from fiducials. This could be used to compute error metrics after a Fiducial to Fiducial registration among other possible uses.
