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
