Hi everyone,

I am trying to calibrate the hires camera after I put the image in focus (see image below), using the following command:
```
voxl-calibrate-camera hires -s 5x7 -l 0.0655
```
I keep getting re-projection error around 15, but it's very hard to understand why. I tried 2 different checkboards of different sizes but I am keep having the same error. Do you have any insights on what might be the issue?
