# Manual camera calibration

{% hint style="danger" %}
Manually editing calibration values or entering custom intrinsics is not recommended unless you are an advanced user. If needed, you can also create a calibration by selecting a starting point from the Camera Presets dropdown.
{% endhint %}

In certain cases you may need to manually configure the calibration parameters for your camera.

To do so:

* Navigate to the Camera section from the right panel on Vozilla
* Select "New Calibration" at the bottom of the panel
* Click the "Advanced" drop down below the image stream
* Click on "Write custom calibration"
* Manually enter your camera calibration parameters in the panel
* When you're done, click the "Save" button

For example, here is the default configuration for a FLIR Boson+ 640 with a 95° HFOV / 4.9mm lens:

```yaml
resolution:
  width: 640
  height: 512

fps: 60

intrinsics:
  fx: 411.37
  fy: 411.22
  cx: 317.80
  cy: 257.89
  k1: 0.133336
  k2: 0.0
  k3: 0.0
  k4: 0.52395
