camera-intrinsic-model

A pure rust camera intrinsic model library. Including

• project / unproject points
• undistort and remap image

Supported camera models are

• Extended Unified (EUCM)
• Extended Unified with Tangential (EUCMT)
• Unified Camera Model (UCM)
• Kannala Brandt (KB4) aka OpenCV Fisheye
• OpenCV (OPENCV5) aka plumb_bob in ROS
• F-theta (FTHETA) by NVidia

For calibration to get the precise parameters. Please use camera-intrinsic-calibration

Examples

# undistort and remap
cargo run -r --example remap

# undistort and rectify
cargo run -r --example stereo_rectify
