Hello,
general information : I use rpi + photon vision .
technical system as in the photo you see
Since I made my vision settings, it reads apriltagi and determines it as a target, but I do not know how to get and process this information in roborio.
can you help me with this. 
You should read the PhotonVision docs. Here are the articles about working with AprilTags in robot code (assuming you program in Java):
Also if you are using labview head up since photo vision does not natively support it … luckily the is a mentor who has made a library for it here. GitHub - jsimpso81/PhotonVisionLabVIEW: PhotonVisionLib for LabVIEW
