A calibration plate carries a grid of dots or checkerboard squares at precise spacing. The vision system images it to correct lens distortion and relate pixel measurements to real-world units, which is the basis for robot guidance and metrology. Cognex supplies such plates in glass, ceramic and metal substrates in sizes matched to the field of view, with certified spacing for demanding work. They are also used to align several cameras in assembly and inspection lines.
