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.
