ICP 有两种经典的error function,参考open3d registration tutorial: point-to- point 2. point-to- plane 这个就不多说了,印象里 motivation 是扫描到的是物体表面而不是孤立的点,所以点到点的loss其实是不太合理的,匹配点应当距离很近并且尽可能的与法向量垂直,基于表面连续的假设。 DICP 的 error function 可...

For each point in the target pointcloud, find the closest point in the scene pointcloud. Compute a 3d tranformation matrix that best aligns the points using Least-Squares-Regression. Update all points in the target by the computed transformation matrix. ...
Methods We propose an algorithm to register point clouds by integrating color information. The key idea of the algorithm is to jointly optimize the dense and edge terms. The dense term was built in a manner similar to that of the iterative closest point algorithm. To build the edge term, ...

as we assumed that3might have steric interference with loop 2 (D156-H162). In addition, the enzyme could not provide potentially sufficient interactions to bind3due to the large unoccupied space appearing in the vicinity of loop 1 (G8-A30) and helix 2 (L186-L196) in the active pocket...
