These parameters are different for each device, so each camera must be calibrated individually to work with these apps. For cameras supported by the **video2ros** service, AuterionOS provides an interface for [uploading an existing calibration file](#upload-a-calibration-file) and tools for [performing a new calibration](#perform-a-new-calibration) and generating a calibration file. ## Upload a calibration file If a camera has already been calibrated and the calibration file is available, it can be uploaded to Skynode. Open the **Apps** page of the vehicle web UI on , find the **video2ros** app under **System Services**, and click the blue **Add calibration file** button. In the calibration webpage that opens, click the button to select a file to upload. Note that only YAML files are accepted. If the file uploads successfully, the **Calibration File Exists** status on the webpage will be **true**.

The calibration webpage after a calibration file has successfully been uploaded.

Restart the **video2ros** app for the uploaded file to be applied.\ Close the calibration webpage and return to the **Apps** page of the vehicle UI. Click the grey gear icon of the **video2ros** app and select **Stop**. Once stopped, click the gear icon and select **Start**. ## Perform a new calibration To perform a new calibration, use the calibration tool provided by Auterion. This can be run on a computer connected to Skynode, or on Skynode itself. Running the calibration on a computer is much faster and is the recommended procedure. Follow the links below for instructions on these two procedures. {% content-ref url="/pages/PFmoQDM7pQNZrS8HgIyI" %} [Camera Calibration on a Computer](/hardware-integration/airframe-integration/camera-calibration/camera-calibration-on-a-computer.md) {% endcontent-ref %} {% content-ref url="/pages/lzSdj4D7TGZrDVs4T1l8" %} [Camera Calibration on Skynode](/hardware-integration/airframe-integration/camera-calibration/camera-calibration-on-skynode.md) {% endcontent-ref %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.auterion.com/hardware-integration/airframe-integration/camera-calibration.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
