DARE

This repository contains a python implementation of the Density Adaptive Point Set Registration (DARE) method. Without the density adaptation, the method is equivalent to Joint Registration of Multiple Point Sets (JRMPC) [1]. Additionally, implementations of Color-based Probabilistic Point Set Registration (CPPSR) [2] and Feature-based Probabilistic Point Set Registration (FPPSR) [3] are provided and can be run together with the density adaptation.

The script reg_demo.py runs DARE on a subsampled version of the vps outdoor dataset.

This method is also included in https://github.com/felja633/RLLReg as a pytorch implementation.

Publication

A detailed description of the DARE method can be found in the CVPR 2018 paper:

Dependencies

• python 3.6
• numpy
• scipy
• matplotlib
• pathlib
• cmake
• pcl (if you want to use FPPSR)

Installation

Make sure that the above dependencies are installed.

• To be able to run FPPSR, you need to build the pybind module in src/pcl_utils at src/pcl_utils/build.

You may use the shell script build_pybind_modules. The code has been tested in Ubuntu 16.04 and 18.04.

Datasets

The full datasets used in the paper can be found at http://www.hdrv.org/vps/ and http://www.prs.igp.ethz.ch/research/completed_projects/automatic_registration_of_point_clouds.html.
