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 as a pytorch implementation.

Publication

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

F. Järemo Lawin, M. Danelljan, F. S. Khan, P.-E. Forssen, and M. Felsberg, “Density adaptive point set registration,” in The IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2018.

@InProceedings{jaremo18a, author = {Felix J\"aremo Lawin and Martin Danelljan and Fahad Khan and Per-Erik Forss\'en and Michael Felsberg}, title = {Density Adaptive Point Set Registration}, booktitle = {{IEEE} Conference on Computer Vision and Pattern Recognition}, year = {2018}, month = {June}, address = {Salt Lake City, Utah, USA}, publisher = {Computer Vision Foundation}, }

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/pclutils at src/pclutils/build.

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