compute_rmse(self, source, target, correspondences)#

Compute RMSE between source and target points cloud given correspondences.

Parameters:

  • source (open3d.t.geometry.PointCloud) – Source point cloud.

  • target (open3d.t.geometry.PointCloud) – Target point cloud.

  • correspondences (open3d.core.Tensor) – Tensor of type Int64 containing indices of corresponding target points, where the value is the target index and the index of the value itself is the source index. It contains -1 as value at index with no correspondence.

Returns:

float
