Status: PARTIAL PASS committed
Right-edge plate boundary detection on A1 detects at ~72-75% of frame vs actual plate edge at ~80%.
What Works
- 11/11 validation passes
- Coverage stable at 50-53%
- Solidity 0.82
Root Cause
Plate edge pixels (luminance 0.35-0.449) are luminance-contiguous with rail at 100°C — cannot separate in RGB luminance.
Possible Fixes
- Canny/Sobel edge detection instead of luminance-only
- Thermal gradient approach
- Accept ~75% as "good enough" for practical use
Current Config
- plate_left=0.05, plate_right=0.95
- Detection crop: 1728x864
- Camera: 1920x1080 TCP/TLS
