In development · Vision-only parking perception · Low-vision coaching HUD

HERO is a coaching-only parking-assistance project for a Hyundai Ioniq. It combines a camera-only perception stack with a driver interface designed around low-vision legibility. Development and measurement run in CARLA; the system provides guidance and does not intervene in vehicle control.

Vision-Only Perception

  • Two-camera ground-plane odometry estimates vehicle motion without vehicle-mounted LiDAR.
  • Plane-sweep dense occupancy reconstructs parking-space geometry in C++/CUDA.
  • A reproducible CARLA evaluation harness compares perception output against an Autoware LiDAR reference.
  • Measurement outputs are separated from the presentation layer so the perception path can be evaluated independently.

Low-Vision Coaching HUD

  • Angular legibility budgets connect display geometry to the driver's usable visual angle.
  • Guidance includes a parking corridor, stop line, gear state, and explicit degraded-state messaging.
  • ROS 2 coaching logic is separated from the Qt presentation layer.
  • The current geometry layer includes 26 tests for display and guidance calculations.

Engineering Status

In development. The current implementation includes a reproducible measurement harness, scenario-driven HUD states, geometry tests, and visual-acuity simulation outputs for interface review.
