This commit represents a major architectural upgrade to the CARLA ADAS simulation project, transitioning from stochastic Traffic Manager behavior to a fully deterministic, high-impact demo environment.
1. Deterministic Scenario Architecture
New Showcase Scenario: Implemented
scenarios/showcase.py
for a manual "Left-Turn Across Path" (LTAP) maneuver.
Physics Velocity Injection: Overrode engine/friction variance by directly setting set_target_velocity for NPC actors at 35 km/h.
Multi-Stage Waypoint Guidance: Integrated EGO_MID and P1_MID transition points to ensure realistic, cinematic turning radii and reliable collision-avoidance timing.
Manual Steering Controller: Developed a proportional steering-to-target helper for all actors.
2. Sensor & Data Pipeline
Dual-Camera Support: Integrated a second Third-Person Perspective (TPP) camera.
Radar Serialization Fix: Implemented trigonometric conversion of raw spherical coordinates (Depth, Azimuth, Altitude) into Cartesian XYZ + Velocity 16-byte PointClouds for Foxglove Studio.
Synchronization: Aligned all sensor data (Dash Cam, TPP Cam, Radar, Lidar) at the orchestrator level.
3. Performance & Asynchronous I/O
Asynchronous Recorder: Refactored
src/recorder.py
to use ThreadPoolExecutor, offloading cv2.imwrite operations to background threads to eliminate simulation stutter.
Rapid Iteration: Added --no-record global flag to
main.py
for sub-second iteration during coordinate tuning.
4. Automation & Seamless UX
Auto-MCAP conversion: Integrated
data_to_mcap.py
as a post-simulation callback in
main.py
.
Auto-Video Stitching: Implement automatic .mp4 generation for both camera views using OpenCV's VideoWriter.
Weather/Time CLI: Added --weather flag with presets (Clear, Rain, Sunset, Night).
Console Sync: Integrated tqdm for professional progress tracking and refactored scenario logging to use pbar.write() to prevent terminal flickering/staircasing.
5. Dependency Updates
Added tqdm as a core dependency for enhanced console visualization.
