High Precision Large Calibration Board Max 1680x3500mm customized

Large-Sized Calibration Board

Large-sized calibration plates typically incorporate conventional patterns such as dots, checkerboards, and QR codes, combined with different scene calibration requirements, making it perfect for large-scale calibration tasks in industrial vision systems, robotics, and automated inspections. Its high contrast ensures clear and accurate calibration over large distances, making it ideal for both indoor and outdoor environments. The extra-large size allows for precise alignment and distortion correction across expansive areas, offering unmatched reliability.

Product Features: Wide field of view, high precision, high stability, exclusive optical materials, high contrast without reflection, integrated molding without splicing, low expansion coefficient, clear pattern corners, and support for diversified customization.

Application scenarios: wide-field industrial inspection, multi-camera stitching detection system, high-position installed vision system, calibration of autonomous driving and intelligent traffic vision system, etc.
