Easiest way to calibrate a camera on Linux. No ROS, no Docker, no CMake. Just FFmpeg and Spectacular AI command line tool installable via Python pip:
sudo apt install ffmpeg
pip install spectacularAI[full]
sai-cli calibrate your-data.mkv
sudo apt install ffmpeg
pip install spectacularAI[full]
sai-cli calibrate your-data.mkv

GPS-free visual-inertial navigation in real time on Raspberry Pi 5 with a consumer-grade IMU and camera (and this is not even the slowest CPU this runs on!)

GPS-free visual-inertial navigation in real time on Raspberry Pi 5 with a consumer-grade IMU and camera (and this is not even the slowest CPU this runs on!)
Latest demo for context: We can position an aircraft with ~20m accuracy (CEP) over a 70+ km flight using only a 5$ IMU sensor, barometer and a fisheye camera.
This video was rendered offline and positions a Cessna instead of an UAV, but the software runs in real-time, on Raspberry Pi -level CPUs.
