Advanced Camera API

February 24, 2019 - 2:08pm #3


I'd like to ask you a question about Advanced Camera API described here: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/Advanced-Camera-API.html

There is a sentence: The Advanced Camera API is only available for certain license types. In Pricing it says, only Pro licence can use Advanced Camera API. Problem is, we are building an OCR application and we are facing some problems with camera settings (such as capture size etc). But we don't know if using if this Advenced Camera API can help us or not. 

Is there any way to try this out? Some testing licence or something like that? $499 for Classic licence means a lot bigger price for Pro. We can't afford buying someting like this if it doesnt help. 


Thanks, ODDT

Have you tried using a Development license to see if that enables the APIs?

I use Development license key. But when there is the thing, if i look at Device logs shown here, I see some usable control keys here, like

Key: picture-size-values; Type: TypeString

Key: video-size; Type: TypeString


and few others. But when I loop through controls on real Android device (i tried 3 devices: Xiaomi Mi8, Samsung Galaxy S8 and Samsung Galaxy Tab 2 S10), I dont see any of these. There is always 121 keys in absolutely different format. Here are some examples:

Key: android.blackLevel.lock, Type: TypeBool

Key: android.colorCorrection.gains, TypeTypeUnknown

Key: android.control.aeTargetFpsRange, TypeInt64Range


First, I can't find any usable settings for me (but in example on web is some size setting). Second, I tried to set some key by calling setField() with some parameters, but I honestly don't know what to use as a key. Is it the key in form from device or from documentation? Btw, after trying to set any setting, it did nothing.
