Welcome to MetriCal
Introduction
MetriCal delivers accurate, precise, and expedient calibration results for multimodal sensor suites. Its easy-to-use interface and detailed metrics enable enterprise-level autonomy at scale.
Anyone can download MetriCal, license not required. Unlicensed users have near-complete use of the software, from processing to metrics generation. The only limitation is the calibration results, which require a license to view and save.
To get started, check out the installation instructions.
What is Sensor Calibration?
Sensor calibration is the process of determining the parameters that define how a sensor captures data from the world. This includes:
- Intrinsic parameters: Properties internal to the sensor itself (like a camera's focal length or distortion)
- Extrinsic parameters: The position and orientation of sensors relative to each other or a reference frame
Good calibration ensures that:
- Measurements from a single sensor are accurate
- Data from multiple sensors can be properly aligned and fused
- Perception algorithms receive consistent, accurate input data
Why MetriCal?
MetriCal provides a comprehensive solution for calibrating various sensor configurations. Unlike many calibration tools that focus on single sensors or specific combinations, MetriCal offers:
- Support for single cameras, multi-camera arrays, LiDAR sensors, and IMU sensors
- Joint optimization of intrinsic and extrinsic parameters
- Detailed uncertainty metrics to assess calibration quality
- Flexible workflows for different calibration scenarios
- Visualization tools to inspect calibration results
- Process ROSbags, MCAP files, and folder datasets.
- Convert a calibration file into a URDF file for easy integration into ROS.
- Use a variety of calibration targets.
- Create pixel-wise lookup tables for both single camera correction and stereo pair rectification.
...and so much more!
