## What it is
OpenCalib is a C++ multi-sensor calibration toolbox for autonomous driving that calibrates IMU, LiDAR, camera, and radar sensors, both intrinsically and extrinsically. It offers target-based and target-less methods with manual and automatic calibration workflows, distributed via a Docker image.

## Use cases
- calibrate lidar to camera extrinsics for autonomous driving
- perform camera intrinsic calibration
- align radar and lidar sensors
- estimate imu heading without calibration targets
- calibrate surround-view camera systems
- set up sensor fusion for a self-driving stack

## When to choose
- you need to calibrate multiple sensor types (lidar, camera, radar, IMU) in one toolbox
- you want target-less road-scene-based auto calibration
- you work on autonomous driving perception or sensor fusion

## When to avoid
- you need calibration for sensors outside IMU/LiDAR/camera/radar
- you want a GUI-driven commercial calibration suite
- your project is not related to autonomous driving or robotics

## Facets
- artifact type: library
- maturity: active
- function: computer-vision, simulation, developer-tools
- domain: autonomous-vehicles, robotics, computer-vision
- platform: cpp
- tags: sensor-calibration, lidar, camera-calibration, imu, radar, extrinsic-calibration, intrinsic-calibration, autonomous-driving, opencalib, linux, docker
