kandi X-RAY | DBoW2 Summary

DBoW2 is a C++ library. DBoW2 has no bugs, it has no vulnerabilities and it has low support. However DBoW2 has a Non-SPDX License. You can download it from GitHub.

DBoW2 is an improved version of the DBoW library, an open source C++ library for indexing and converting images into a bag-of-word representation. It implements a hierarchical tree for approximating nearest neighbours in the image feature space and creating a visual vocabulary. DBoW2 also implements an image database with inverted and direct files to index images and enabling quick queries and feature comparisons. The main differences with the previous DBoW library are:. DBoW2 requires OpenCV and the Boost::dynamic_bitset class in order to use the BRIEF version. DBoW2, along with DLoopDetector, has been tested on several real datasets, yielding an execution time of 3 ms to convert the BRIEF features of an image into a bag-of-words vector and 5 ms to look for image matches in a database with more than 19000 images.

Undefined Reference While Compiling ROS ORB_SLAM2

I am trying to compile this version of ORB SLAM2 and after fixing some library import errors, I got this:

This is an annoying compatibility error. The ORB SLAM you are trying to use only works with Ubuntu 18.04. But, on the ROS ORB SLAM page, they have a new one called orb_slam_ros (click here) that does the same thing.

NOTE: The new one doesn't say that it outputs ROS maps but using Octomap, you can convert a PointCloud to a Map. NOTE: This is tested in Ubuntu 20.04 ROS Noetic. As of now, 20.10 doesn't work.
