# CV Inspection Overlay Report

**Date:** 2026-07-09  
**Status:** Implemented

---

## What Was Added

### 1. CV Inspection Overlay (`src/components/CVInspectionOverlay.tsx`)

Industrial camera monitor style panel showing:
- Item title
- Detected shape (box / cylinder / round / irregular)
- Dimensions (W × D × H mm) with pass/fail indicator
- Roundness K value with ≥0.7 warning
- Confidence % with LOW warning
- Classification result (B/C/D)
- Command (ROUTE_TO_*)
- Warning messages (low confidence, C priority)

### 2. Inspection View Model (`src/domain/inspectionViewModel.ts`)

Data adapter providing:
- `InspectionData` interface
- Phase-based visibility logic
- Dimension fail detection
- Roundness fail detection
- C-priority indicator

### 3. 3D Visual Effects (in `SorterDigitalTwinContinuous.tsx`)

**Camera Rig:**
- Overhead frame with cross beam
- Support poles
- Camera unit with lens
- Laser emitters on sides
- Active highlight when detecting

**Inspection Zone:**
- Rectangle on belt under camera
- Corner markers
- Active highlight

**Scan Line:**
- Animated cyan line sweeping across detection zone
- Only visible during detection phase

**Bounding Box:**
- Wireframe around item during measurement
- Dimension lines (dashed)

**Shape Outline:**
- Circle for round items (D category)
- Square for box items (B/C)
- Colored by category

### Key Screenshots

**inspection_detection.png:**
- Camera rig visible
- CV overlay shows "Measuring dimensions"
- Dimensions displayed: 300 × 200 × 200 mm (green = pass)

**c_priority_inspection.png:**
- Case 7: "Негабарит + круглый"
- SIZE: 500 × 300 × 300 mm (red = fail)
- ROUNDNESS: 0.93 (red = ≥0.7)
- CLASS: C (C priority) — correct priority over D

**low_confidence_warning.png:**
- Case 8: "Low confidence fallback"
- CONFIDENCE: 58% LOW (orange warning)
- Warning: "Low confidence is a warning, not a 4th category"
- CLASS: B (rule-based still works)

```

**Browser QA:**
- ✓ CV overlay visible during inspection
- ✓ Camera rig renders correctly
- ✓ Scan line animates
- ✓ Bounding box appears
- ✓ Shape outline visible
- ✓ Dimensions pass/fail highlighted
- ✓ Roundness warning shown
- ✓ Low confidence warning shown
- ✓ C-priority indicator works
- ✓ No console errors

---

## Build/Test Results

```
✓ npm run build — success
✓ npm run test — 59 tests passed
✓ docker rebuild — success
```

---

## What Remains

- Fine-tune scan line animation speed
- Optional: Add laser beam visualization
- Optional: Camera view-in-view widget

feat: add CV inspection overlay with visual effects

- Add CVInspectionOverlay component (industrial camera monitor style)
- Add inspectionViewModel adapter for playback → inspection data
- Add camera rig with overhead frame and laser emitters
- Add inspection zone highlight on belt
- Add animated scan line during detection
- Add bounding box wireframe during measurement
