Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

improving camera pose estimation using multiple aruco markers
Most of the code in pytagmapper is geared towards building said map, using an algorithm called SLAM. Nowadays, SLAM is usually implemented by solving a numerical optimization problem. The pytagmapper project uses a variant called Gaussian Belief Propagation. Other more popular variants, are some form of EKF or Levenberg Marquardt. You can try using pytagmapper to build your map, or some other SLAM software. Googling "aruco tag slam" gives this ROS based project https://github.com/ydsf16/aruco_ekf_slam for example.

2D images to 3D Object reconstruction
You're looking into a problem called photogrammetry, and a well-studied one at that. I'd recommend looking into "shape from motion" (sfm); specifically techniques that do "dense reconstruction." I'd recommend COLMAP to start with. It does pose estimation from images (e.g. you point it at a bunch of images and it will figure out the relative poses of the cameras that took them), as well as sparse and dense reconstcution.

3D reconstruction of an object from videos/few images
Classical photogrammetry, where I agree with u/tdgros that the way to go is https://colmap.github.io/. There are actually better variants in literature but nothing is more reliable and user-friendly than COLMAP. This will give you a very precise point cloud, that can be meshed if needed.
