How to select calibration boards

Choose an appropriate calibration board based on the size of the field of view, usually selecting half or one-third of the field of view. The so-called field of view has many concepts: camera field of view (which is built-in in camera parameters and usually does not require us to calculate it ourselves); Calibrate field of view (object field of view, which can be understood as the field of view we refer to)

 

Material differentiation

advantage

shortcoming

ceramics

The advantages of ceramic calibration plates are non reflective and high contrast

Due to material limitations, the pattern is ≤ 200 * 200mm, and the material is expensive, making it difficult to process with high precision and resulting in a high scrap rate

glass

The advantages of glass calibration plates are that they can process high-precision patterns with a surface width of 690 * 590mm, with high precision. The processing technology is relatively mature compared to ceramics, and the price is cost-effective

Reflective and fragile
