Why MetriCal?
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.
However, that may not mean anything to you! You might just be here because calibration is a Thing That Needs Doing for your perception system. Not a problem; before diving into the specifics of MetriCal, let's discuss why a tool like MetriCal is essential for modern sensor setups.
If you're looking for a real-world example of how MetriCal has been used to solve a calibration challenge in your domain, check out Tangram Vision's case studies page. Who knows! You might help us write the next one.
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, IMU sensors, and local navigation systems
- 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 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!
