• This app trying to change camera exposure to low (image will be dark), it may not work in your device. camera sittings can be found in here
• Need to give camera permissions for the app to work
• If you changing openCV version add all the folders in sdk\native\libs from your new openCV version to jniLibs folder
• Tested on samsung galaxy A5 2017, you can see here the performance when running it in 30FPS and 320X240

you can also see here 2020 field target images

• phone battery level
• FPS
• Don't have connection (no one is reading vision data)
• Counters, Target and target error

The servers will send value and responds only when the app is open and running on your phone!

• MjpgServer stream final mat (app view) to port 5800 in 15 FPS
• VisionConstantServer get request to change vision values to port 5801, to view web vision value config send a request from your browser to <Phone-IP>:5801 (you can see images of web vision config here)
• VisionDataServer send string with vision data (isTargetValid;x;y => true;-0.711;-0.417) to port 5802 (you can use client.py to read vision data value but change the host)
