# Write image parameters¶

The SDK provides a tool img_params_writer for writing image parameters. For details, read tools/README.md .

For getting image parameters, please read Get image calibration parameters. This is used to calculate the deviation.

Reference commands:

./tools/_output/bin/writer/img_params_writer tools/writer/config/img.params

# Windows
.\tools\_output\bin\writer\img_params_writer.bat tools\writer\config\img.params


And, tools/writer/config/img.params is the path of parameters file. If you calibrated parameters yourself, you can edit it and run previous commands to write them into the devices.

Tip

You can also write into devices with SN*.conf provided by old SDK.

Warning

Please don’t override parameters, you can use save_all_infos to backup parameters.
