1. Overview

kapture-localization is a toolbox in which you will find implementations for various localization related algorithms. It strongly relies on the kapture format for data representation and manipulation.

The localization algorithms include:

1. mapping,

2. localization, and

3. benchmarking (image retrieval for visual localization).

It works on Ubuntu, Windows, and MacOS.

2. Structure

The directories are organised as follow:

├── kapture_localization/  # package (library)
├── pipeline/              # main programs executing all steps of the localization pipelines
├── samples/               # some sample data
├── tests/                 # unit tests
└── tools/                 # sub programs involved in the pipeline

The kapture-localization toolbox is available as:

• Python package (kapture_localization/),

• Python executable scripts (pipeline/ & tools/).

There are 3 pipelines available:

1. mapping,

2. localization, and

3. image retrieval benchmark (global sfm, local sfm, pose approximation).

3. Installation

It can be installed using docker, pip or from manually from source code. After installing python (>=3.6) and COLMAP (>=3.6), this toolbox can be installed with:

pip install kapture-localization

See doc/installation.adoc for more details.

4. Tutorial

See doc/tutorial for a short introduction and examples of the provided processing pipelines.

5. Contributing

There are many ways to contribute to the kapture-localization project:

• provide feedback and suggestion,

• submit bug reports in the project bug tracker,

• implement a feature or bug-fix for an outstanding issue,

• provide scripts to create data in kapture format (e.g. local/global feature extraction),

• propose a new feature and implement it.

If you wish to contribute, please refer to the CONTRIBUTING page.
