LiDAR–Camera Calibration Targets: How to Choose a Board Both Sensors Can See
A camera reads the pattern; a lidar reads the plane and edges. This guide compares four target types and shows how to size a board for both sensors.
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.
How to Clean a Calibration Target — Safely, Without Damaging the Pattern
How to safely clean a glass or ceramic calibration target — removing dust, fingerprints, and marks without scratching the pattern, plus which solvents to use, what to avoid, and how to store it.
Camera Calibration Targets: How to Choose the Right Pattern, Substrate, and Accuracy
A camera calibration target is a precisely patterned plate that gives a camera a field of known reference points. Choosing one comes down to pattern type, substrate and accuracy, physical size, and toolchain fit — and the target, not the algorithm, sets your accuracy ceiling. A navigational overview that links to each in-depth guide.
