The Best Calibration Targets and Test Charts: A Complete Comparison by Use
A comparison of the most widely used calibration targets and test charts, organised by what they measure rather than lumped together. Geometric targets — checkerboard, ChArUco, dot grid, AprilGrid — solve camera geometry and distortion; resolution and image-quality charts — USAF 1951, ISO 12233, ISO 15739 — measure sharpness, resolution and noise. Definitions, applications, the software each pairs with, and where to buy.
