Driver warning system

Flutter mobile application connected to Jetson AGX Xavier via USB to give following driver warnings in real time. (visual and sound warning)

• Traffic light ahead
• Left lane departure
• Right lane departure

Methodology

1. Jetson AGX Xavier writes the 2 json files in path Downloads/fyp when new traffic lights / lane departure is detected.

   lane_departure_data.json

   {
   "json_id": 4,
   "beta": 0.8259314894676208
   }
   

   for each overwrite json_id has a new value

   • beta < 0 => right lane departure
   • beta > 0 => left lane departure

   

   traffic_light_data.json

   {
   "json_id": 39,
   "count": 2,
   "ids": [
       42,
       44
   ]
   }
   

   

   for each overwrite json_id has a new value

   • count - number of detected and tracked traffic lights
   • ids - tracking ids of detected and tracked traffic lights

2. Mobile app reads the json files periodically every 200ms. Check whether New traffic lights / lane departure is detected and show the warnings.
