Orthogonal Plane-based Visual Odometry (OPVO)

This package provides a Matlab implementation of BMVC 2017 paper: "Visual Odometry with Drift-Free Rotation Estimation Using Indoor Scene Regularities" for the purpose of research and study only.

2. Prerequisites

This package depends on mexopencv library for keypoint processing, KLT tracking, and translation estimation. cv.* functions in this package cannot run without mexopencv install in Matlab environment. Please, build mexopencv in your OS first, and then run this package.

3. Usage

• Download the ICL-NUIM dataset from https://www.doc.ic.ac.uk/~ahanda/VaFRIC/iclnuim.html, 'of kt3' is recommanded.

• Or, Use the ICL-NUIMdataset/of_kt3/ included in this package.

• Define 'datasetPath' correctly in your directory at setupParams_ICL_NUIM.m file.

• Run OPVO_core/main_script_ICL_NUIM.m which will give you the 3D motion estimation result. Enjoy! :)

4. Publications

The approach is descirbed and used in the following publications:

• Linear RGB-D SLAM for Planar Environments (Pyojin Kim, Brian Coltin, and H. Jin Kim), ECCV 2018.

• Indoor RGB-D Compass from a Single Line and Plane (Pyojin Kim, Brian Coltin, and H. Jin Kim), CVPR 2018.

• Low-Drift Visual Odometry in Structured Environments by Decoupling Rotational and Translational Motion (Pyojin Kim, Brian Coltin, and H. Jin Kim), ICRA 2018.
