Hi,  
Is there a simple software/application that I can use with ZED2i camera to recognize RGB values in the specific area of the frame?  
Retrive RGB values from that area?

I am a non-programer and would be very helpful just to see how specific colors are recognized by the camera.

Thank you very much for the answers

Hi,

You will need to program a little bit but that’s really simple.  
Just use this sample as a base :

> **[GitHub - stereolabs/zed-opencv: ZED SDK interface sample for OpenCV](https://github.com/stereolabs/zed-opencv)**
>

Once in Opencv, you can directly use all functions from OpenCV where there is many examples on the web.
