Irregular Shaped Custom Calibration Target High Precision Visual Calibration Board

Irregular-Shaped Calibration Target

The alien calibration board (asymmetric circular grid calibration board) is a high-precision visual calibration tool that combines the advantages of both checkerboard and ordinary circular grid calibration boards. It is one of the three mainstream calibration boards supported by OpenCV.

Product Features: Non-planar visual system calibration, multi-view camera calibration, and calibration for irregular shapes such as circles, polygons, and arcs；It exhibits strong resistance to light interference and demonstrates excellent performance in feature point localization accuracy, making it suitable for high-precision calibration scenarios.
Customizable special shapes and patterns can meet the calibration needs of special imaging systems that cannot be adapted by conventional calibration boards.

Applicable scenarios: Machine vision calibration (in fields such as medical, robotics, aerospace, etc.)
