The PCL Registration API The problem of consistently aligning various 3D point cloud data views into a complete model is known as registration. Its goal is to find the relative positions and orientations of the separately acquired views in a global coordinate framework, such that the intersecting areas between them overlap perfectly PCLのインストール PCL、3rdPartyともにall-in-oneインストーラを使用したものと 3rdPartyはインストーラで、PCLは自分でcmakeを使ってビルドする2パターンを試しました。 結果的にはあまり変わらなかったので、all-in-oneが楽かと思います Different variants of ICP use different objective functions E(T) Point-to-point ICP에서는 아래 object를 사용 였다. Paul J. Besl and Neil D. McKay, A Method for Registration of 3D Shapes, PAMI, 1992. Point-to-plane ICP에서 Point cloud registration, is the process of finding a spatial transformation that aligns two point clouds. The purpose is to merge point clouds of multiple views into a globally consistent model

First learn the examples and than build your own (from the trunk) pcl. The previous diagram illustrates how the procedure is done. ICP registration: ICP stands for Iterative Closest Point. It is an algorithm that will find the best transformation that minimizes the distance from the source point cloud to the target one 1.

Iterative closest point (ICP) is an algorithm employed to minimize the difference between two clouds of points.ICP is often used to reconstruct 2D or 3D surfaces from different scans, to localize robots and achieve optimal path planning (especially when wheel odometry is unreliable due to slippery terrain), to co-register bone models, etc

Many variants of ICP have been proposed, affecting all phases of the algorithm from the selection and matching of points to the minimization strategy

The Iterative Closest Point (ICP) algorithm is one of the most widely used methods for point-set registration. However, being based on local iterative optimization, ICP is known to be susceptible to local minima. Its performance critically relies on the quality of the initialization and only local optimality is guaranteed. This paper presents the first globally optimal algorithm, named Go-ICP. How can you create custom ones directly in the code that would make sense for registration?
