PyDBoW3

This repo is a fork of this adapted to opencv4 and added a cmake to find numpy

Get started

import pydbow3 as bow
voc = bow.Vocabulary()
voc.load("PyDBoW3/modules/dbow3/orbvoc.dbow3")
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

Install

• clone the repo with --recursive
• build and install modules/DBoW3 using dbow.sh
