Hi Duvi,&nbsp;

After running Step 1. the optimized camera parameters are saved in:

- The quality report, section&nbsp;[Internal Camera Parameters for Perspective Lens](https://support.pix4d.com/hc/en-us/articles/202558679-#label09).
- The results folder, […\1\_initial\params](https://support.pix4d.com/hc/en-us/articles/202558649-) (calibrated\_camera\_parameters).

As a side note, parameters b1 and b2 are not optimized and included in the results.&nbsp;

Best,
