Is it possible to recognise light patterns on iOS?
Is there a native iOS SDK to do so?
Use case: Detect light patterns (e.g. on / off) using smartphone camera
Background information: Apple has acquired last year Metaio so I presume at some point we will have such SDK, but for now I presume that the best way to achieve this is by using third party SDK or using image capturing and processing the image (if the images are simple enough so that a simple algorithm can be applied).
You could take a look at Kudan AR. https://www.kudan.eu/
They currently offer a SDK for iOS, not yet for Android. Their tracking quality is phenomenally good. But, I do not know if it is appropriate to your goals. It would be best if you talk to them and ask if their tracking would fit your needs.
