SuperPoint_SLAM VS ORB_SLAM2

Hi everyone, I am trying to implement a VSLAM with DNN specifically the Feature Extraction module in the SLAM pipeline. Something on the lines of this repo Superpoint_SLAM , which integrates SuperPoint Feature extraction into ORB_SLAM2

As you've mentioned, there are many papers on deep local feature extraction, like SuperPoint and R2D2. If you wish to use them in SLAM, you can simply replace the feature extraction module in the existing SLAM system with the deep local feature method. An example is shown here - this system uses SuperPoint as local features instead of ORB features in the original ORB-SLAM 2 pipeline. https://github.com/KinglittleQ/SuperPoint_SLAM

Maybe you could give Orb-SLAM2 a try with a Pi cam. The package says it works with a monocular camera. https://github.com/raulmur/ORB_SLAM2

I am thinking about migrating ORBSLAM2(written in cpp) to python3. Currently there are only python3 wrappers for ORBSLAM2, like ORB_SLAM2-PythonBindings and pyORBSLAM2. The biggest problem is that I can't easily and quickly improve, change all the stuff in cpp, as it would be in python. I am aware that the cpp code is much faster the python equivalent, but implementing and improving additional features is much easier in python, at least for me. For converting the code, I'll keep the optimization stuff like g2o(g2opy), pangolin(pypangolin) and DBoW2(pyDBoW) in cpp, but the rest should be in pure python code.

This repo has an advanced SLAM implementation. They also link to a few research papers about how this group made this SLAM algorithm. The ORB SLAM 2 paper has all of the parts of modern SLAM systems, so I'd read that, and the other papers if you have time at the end.

Example: https://github.com/raulmur/ORB_SLAM2/blob/f2e6f51cdc8d067655d90a78c06261378e07e8f3/Examples/ROS/ORB_SLAM2/src/ros_stereo.cc#L71

I'm not sure what your final application is, but you can use a SLAM algorithm to recover your camera trajectory. I've used ORB SLAM 2, and it's pretty nice.
