USAF1951 Test Target

ISO12233 Test Target

IEEE Test Target
Utilizes correspondence between geometric centers of circles and 3D world coordinates to solve camera intrinsic, extrinsic, and distortion parameters. More suitable for high-precision positioning scenarios compared to checkerboards. Commonly used for semiconductor wafer inspection camera calibration, distortion correction in microscopy imaging systems, and joint calibration of LiDAR and cameras in autonomous driving.

Halcon Circle/Dot Pattern
Utilizes correspondence between geometric centers of circles and 3D world coordinates to solve camera intrinsic, extrinsic, and distortion parameters. More suitable for high-precision positioning scenarios compared to checkerboards. Commonly used for semiconductor wafer inspection camera calibration, distortion correction in microscopy imaging systems, and joint calibration of LiDAR and cameras in autonomous driving.
