cannot calibrate color Astra mini camera

[han88]

hi if I try to calibrate my Astra mini camera from the color stream /camera/color/image_raw with the ros calibration pkg the saved calibration file is depth_serialnumber. yaml.. if I change the name to rgb_serialnumber. yaml it's not recognized... I launch the astra mini with the Astra. launch file... what do I have to change? thanks in advance

I've updated the readme. I hope that makes it clear.

• Set camera info uri, Go to xxx.launch

- calibration file should like
```yaml
image_width: 640
image_height: 480
# The camera name is fixed. The color camera is rgb_camera, the depth/IR camera is depth_camera
