Pybind11 interface for DBoW3

PyDBoW3

This repo functions mostly the same with this, but is less heavy. It does not rely on Boost, I have re-written most of the code to utilise the power of pybind11.

Get started

import pydbow3 as bow
voc = bow.Vocabulary()
voc.load("ORBvoc.txt")
db = bow.Database()
db.setVocabulary(voc)
# extract features using OpenCV
...
# add features to database
for features in features_list:
   db.add(features)

# query features
feature_to_query = 1
results = db.query(features_list[feature_to_query])

Prerequisites:

• OpenCV
• CMake
• DBoW3

Install

• clone the repo with --recursive
• build and install modules/DBoW3
• install with pip install .
• currently only *nix is supported
