3D Stereo QR Code Calibration Board (AprilGrid)
Description: The 3D Stereo QR Code Calibration Board (AprilGrid) is a high-precision calibration target designed for stereo vision and multi-camera systems. Based on the AprilTag fiducial system, it features an array of uniquely identifiable QR-like markers that enable robust and unambiguous feature detection. Compared with traditional checkerboards or dot grids, AprilGrid supports large field-of-view setups and ensures high accuracy even under partial occlusion. The board is widely used for intrinsic and extrinsic calibration, stereo camera alignment, SLAM, and 3D reconstruction. With durable materials and precise manufacturing, it provides stable, repeatable results in robotics, autonomous driving, and industrial vision applications.
Product Details
The polyhedron calibration board is designed through a three-dimensional structural approach, integrating high-precision calibration patterns (such as checkerboard grids and dot arrays) on multiple spatial surfaces to achieve multi-view high-accuracy data acquisition. It serves as an efficient core carrier for multi-sensor fusion calibration, effectively enhancing calibration efficiency and system-level precision capabilities.
Product Features: High precision, wide field of view, multi-angle coverage, high stability, efficient calibration capability, etc., with options for solution design and integrated customization.
Applicable Scenarios: Suitable for robotics, panoramic cameras, 3D vision and measurement, intelligent vehicles, and other fields.
