It is an implementation for the paper “PKSS-Align”. The source code will be released when the paper is accepted. The complied version and related exe file are released at first for testing.
This work is an improved version based on KSS-ICP. It can be used to register point clouds with large difference of poses, different scales, noisy points, and defective parts at the same time. With a well designed GPU-based structure, the computational efficiency is improved obviously.

In this part, we introduce some selected methods to estbalish comparsions in different registration tasks. Test datasets and codes of all selected methods are provided in this repository. Some registration instances and related quantitative anlayis reports are shown at the same time. We hope such data can help some ones who are focus on point cloud-based registration research work.

We test selected methods and PKSS-Align in the two datasets: ModelNet40 and S3DIS.
The registration test datasets have been prepared (here), which contains different source point clouds with various influnece factors, template point clouds, and related ground truth transformations.
The quantitative anlaysis results are shown in following tables:
