What is calibration board?

The calibration boards are produced using high-resolution prints mounted on optically flat glass. Each one is individually machine inspected to ensure dimensionally accurate results. Note: The calibration boards do not come with its own stands and have to purchased separately. Physical Dimension: 70 x 70mm. One-sided.

Why checkerboard is used for camera calibration?

Camera calibration is a key step in three-dimensional (3-D) reconstruction, and its accuracy directly affects the final effect and quality of the 3-D models. In computer vision, the checkerboard pattern is widely used for camera calibration because it is easily produced and enables high accuracy.

What are calibration targets?

A calibration target is a reference object that consists of a defined shape grid pattern manufactured to a surface. The target is used to calibrate the projection of a DIC experiment together with the Dantec Dynamics' DIC software, Istra4D.
