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.

Syncing video with sensor data for creating a learning dataset
Well. Or you can solve the problem by using this Kalibr tool.

ZED 2 Kalibr Calibration
There is another person who encountered - seemingly - the same issue https://github.com/ethz-asl/kalibr/issues/426 but there are unfortunately no tips on how to fix this.

Camera Calibration Tool (Pinhole) w/ Re-projection Error Metric
I have tried to compile this one https://github.com/hengli/camodocal but I always get an error, and it looks like the repo is no longer being maintained. https://github.com/ethz-asl/kalibr This one works but it looks like it doesn't provide any error estimate/"goodness" score. I also tried to write my own tool with OpenCV but there I get huge re-projection errors (~1E20). And the ROS http://wiki.ros.org/camera_calibration package also doesn't provide any metric (as far as I can tell).

Best library for calibrating 3 cameras?
Would recommend Kalibr https://github.com/ethz-asl/kalibr

I created a better checkerboard detection algorithm written in Python!
A major problem with intrinsic calibration is the lack of open source libraries that can accurately detect highly distorted, high density checkerboards. OpenCV and other surface level detection libraries are pretty much unusable for anything other than low density checkerboards. MATLAB has a great package, but it is obviously closed source and is pretty slow. Libcdetect is okay, but there are only versions written in MATLAB and C++ (and I have no idea how to use C++ haha. Let me know if you know how to use this C++ package!).
What are some alternatives?
When comparing kalibr and libcbdetect you can also consider the following projects:
Firebeetle-2-ESP32-E - Using the Firebeetle ESP32-E as battery powered sensor (SKU:DFR0654-F)
camodocal - CamOdoCal: Automatic Intrinsic and Extrinsic Calibration of a Rig with Multiple Generic Cameras and Odometry
infidel-sensor - Firmware, mechanical and electrical design files for the Inline Filament Diameter Estimator, Lowcost (InFiDEL).
