Thanks for the reply.

Instead I bought a camera Trust (Amazon link to https://www.amazon.it/Trust-SpotLight-Webcam-risoluzione-1280/dp/B0028YR4DW/ref=sr_1_4?adgrpid=67764935006&gclid=Cj0KCQjw1MXpBRDjARIsAHtdN-2oanlbM5S6SI5_ENifYQmzzlnZPsHn4nyfhBnwVdYaNb6my8ZWCAMaAtHcEALw_wcB&hvadid=342601536426&hvdev=c&hvlocphy=1008560&hvnetw=g&hvpos=1t1&hvqmt=b&hvrand=2431037372961623403&hvtargid=kwd-295086869496&hydadcr=25703_1770737&keywords=trust+camera&qid=1563520401&s=gateway&sr=8-4) connecting it to my smartphone's micro USB input via micro USB adapter. Following the UVC guide actually gives me Vuforia initialization error. Is it due to the fact that the Trust camera is not compatible with Android and Vuforia devices? Or is it a problem with my code? I add that I followed the guide slavishly.

Finally, my final goal for work reasons should be to elaborate through Vuforia the video frames coming from the Da Vinci Robot used in the surgical field. In particular the video frames taken from the Da Vinci endoscope camera should be directed towards an Android device where they must be processed with the Vuforia tool. Do you think it's possible?

Hello,

The External Camera feature is meant to "unlock" the Vuforia Engine SDK's input interface to cameras other than ones that are embedded on a smartphone. I can think of no reason why your cameras would not work with the feature as the driver code, which interfaces with the SDK, is in the hands of the developers to create and optimize.

One thing to be aware of is the distortion present in wide-angle lenses. This can potentially impact target detection and/or the accuracy of the tracking. Thus, I recommend you provide the intrinsic calibration data for the model you choose. Please review the following article: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/external-camera-calibration.html

Thanks,
