A Calibration board with light source is a specialized calibration target designed to enhance accuracy under varying lighting conditions. This board incorporates built-in light sources, such as LEDs, to ensure consistent and uniform illumination across the calibration pattern, reducing errors caused by shadows or uneven ambient light. It is commonly used in machine vision, robotics, and industrial inspection systems where precise camera calibration is critical. Illuminated calibration boards are available in various sizes, from small compact boards suitable for laboratory setups to large boards for industrial-scale applications. They can be made from durable materials like acrylic or aluminum, and are compatible with both 2D planar and 3D calibration setups, providing high reliability in challenging lighting environments.
