FAST-Calib LiDAR–Camera Extrinsic Calibration Target

The FAST-Calib LiDAR–Camera Extrinsic Calibration Target is a professional-grade LiDAR–camera calibration target for accurate, repeatable camera–LiDAR extrinsic calibration. This hybrid calibration board combines large circular LiDAR features with ArUco fiducial markers, enabling reliable detection across both camera images and LiDAR point clouds.
The target is optimized for FAST-Calib calibration workflows and similar multi-sensor calibration pipelines used in robotics, autonomous vehicles, SLAM, and sensor-fusion systems.

What This LiDAR–Camera Calibration Target Is Used For

Camera–LiDAR Extrinsic Calibration

This calibration target is used to determine the exact spatial relationship (rotation and translation) between a camera and a LiDAR sensor. Accurate extrinsic calibration is essential for:

• Aligning 2D camera imagery with 3D LiDAR data
• Improving sensor fusion and perception accuracy
• Supporting autonomous navigation and mapping
• Reducing calibration drift in multi-sensor systems

By using both visual fiducials and geometric LiDAR features, this board enables robust, automation-friendly calibration in real-world conditions.

Why a Hybrid LiDAR–Camera Calibration Board Works Better

This target uses two complementary feature types, each optimized for a different sensor modality.

This hybrid approach significantly outperforms checkerboard-only targets for LiDAR camera calibration.

FAST-Calib LiDAR–Camera Extrinsic Calibration Target Features

UV direct printing delivers sharp, high-contrast fiducial markers and geometric features required for accurate camera detection. UV-cured inks offer long-term fade resistance, making the target suitable for extended use in indoor and outdoor environments.

Camera–LiDAR calibration depends on precise geometry. Each target is precision-manufactured using automated cutting processes to ensure consistent feature placement, dimensional accuracy, and repeatable calibration results.

This FAST-Calib calibration target is manufactured in its unique, application-specific shape, with precision cutting to ensure accurate geometry and consistent results.

The anti-reflective surface minimizes glare and unwanted reflections, helping maintain reliable camera detection and consistent LiDAR returns across a wide range of lighting conditions.

Anti-Reflective, Near-Lambertian Surface

(Ultra-Matte Finish · Near-Lambertian Surface on ACM)

All FAST-Calib calibration targets are produced using our ultra-matte printing process, creating a highly diffuse white surface that minimizes glare and variation in reflectance. When printed on ACM (Aluminum Composite Material), the full-coverage, UV-cured white ink exhibits near-Lambertian reflectance across the visible and near-infrared spectrum.

This helps maintain consistent corner and feature contrast across viewing angles, reducing specular highlights and uneven reflections that can introduce detection errors—particularly in uncontrolled lighting or during calibration of active sensors. The UV-ink surface on ACM is scratch-resistant, rigid, and durable, making it well-suited for both indoor and outdoor calibration environments.
