# Preparing the checkerboard

 

**Note:** The checkerboard is used for intrinsic and extrinsic calibrations.

The accuracy of intrinisic and extrinsic calibration depends heavily on the **physical quality** of the checkerboard. Rigidity, correct scale, and surface finish are critical.

### Board Requirements

- **Image:** [A1.zip](https://docs.move.ai/hubfs/A1.zip?hsLang=en)
- **Material:** Print the provided checkerboard pattern with matt-over-laminate on an **A1 aluminium honeycomb or aluminium composite board**. 
    - IMPORTANT: The board must remain perfectly flat. Any bending or warping will reduce calibration accuracy.
- **Printing:** Print at **100% scale** (do not use *scale to fit*).
- **Finish:** Use a **matte finish** to prevent glare.

**Verification**

After printing, verify the squares are 80x80mm with a ruler to confirm accurate scale.
