# Capture d'Élément Cible VWB - Diagnostic
|
||||
Auteur : Dom, Alice, Kiro - 09 janvier 2026
|
||||
|
||||
## Problème identifié
|
||||
La capture d'élément cible ne fonctionne pas via l'API Flask mais fonctionne en direct.
|
||||
|
||||
## Fichiers clés
|
||||
- visual_workflow_builder/backend/app_lightweight.py : Backend Flask principal
|
||||
- visual_workflow_builder/frontend/src/components/VisualSelector/index.tsx : Composant frontend
|
||||
- tests/integration/test_capture_element_cible_vwb_09jan2026.py : Test principal
|
||||
- tests/integration/test_backend_vwb_simple_09jan2026.py : Test direct backend
|
||||
|
||||
## Tests à exécuter
|
||||
1. Test direct : python3 tests/integration/test_backend_vwb_simple_09jan2026.py
|
||||
2. Test complet : python3 tests/integration/test_capture_element_cible_vwb_09jan2026.py
|
||||
|
||||
## Environnement requis
|
||||
- Environnement virtuel venv_v3 avec mss, pyautogui, torch, open_clip_torch
|
||||
- Python 3.8+
|
||||
- Écran disponible pour capture
|
||||
|
||||
## Symptômes
|
||||
- ✅ Fonctions backend directes : OK
|
||||
- ❌ Endpoints Flask /api/screen-capture : Erreur 500
|
||||
- ✅ ScreenCapturer avec venv : OK
|
||||
- ❌ ScreenCapturer via serveur Flask : Échec

# Implémentation Capture d'Écran et Embedding Visuel - VWB
|
||||
|
||||
**Auteur : Dom, Alice, Kiro - 09 janvier 2026**
|
||||
|
||||
## Résumé
|
||||
|
||||
Cette documentation décrit l'implémentation des endpoints de capture d'écran et de création d'embeddings visuels pour le Visual Workflow Builder (VWB).
|
||||
|
||||
## Fonctionnalités Implémentées
|
||||
|
||||
### 1. Endpoint `/api/screen-capture` (POST)
|
||||
|
||||
Capture l'écran actuel et retourne l'image en base64.
|
||||
|
||||
**Request Body (optionnel):**
|
||||
```json
|
||||
{
|
||||
"format": "png",
|
||||
"quality": 90
|
||||
}
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"screenshot": "base64_encoded_image...",
|
||||
"width": 1920,
|
||||
"height": 1080,
|
||||
"timestamp": "2026-01-09T13:41:18.123456"
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Endpoint `/api/visual-embedding` (POST)
|
||||
|
||||
Crée un embedding visuel à partir d'une capture d'écran et d'une zone sélectionnée.
|
||||
|
||||
**Request Body:**
|
||||
```json
|
||||
{
|
||||
"screenshot": "base64_encoded_image...",
|
||||
"boundingBox": {
|
||||
"x": 100,
|
||||
"y": 200,
|
||||
"width": 150,
|
||||
"height": 50
|
||||
},
|
||||
"stepId": "step_123"
|
||||
}
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"embedding": [0.1, 0.2, ...],
|
||||
"embedding_id": "emb_step_123_20260109_134118",
|
||||
"dimension": 512,
|
||||
"reference_image": "emb_step_123_..._ref.png",
|
||||
"bounding_box": {
|
||||
"x": 100,
|
||||
"y": 200,
|
||||
"width": 150,
|
||||
"height": 50
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Endpoint `/api/visual-embedding/<embedding_id>` (GET)
|
||||
|
||||
Récupère un embedding existant par son ID.
|
||||
|
||||
### 4. Endpoint `/api/visual-embedding/<embedding_id>/image` (GET)
|
||||
|
||||
Récupère l'image de référence d'un embedding.
|
||||
|
||||
## Architecture Technique
|
||||
|
||||
### Services Utilisés
|
||||
|
||||
1. **ScreenCapturer** (`core/capture/screen_capturer.py`)
|
||||
- Capture d'écran via `mss` ou `pyautogui`
|
||||
- Support multi-moniteur
|
||||
- Buffer circulaire pour historique
|
||||
|
||||
2. **CLIPEmbedder** (`core/embedding/clip_embedder.py`)
|
||||
- Modèle ViT-B/32 OpenAI
|
||||
- Embeddings de dimension 512
|
||||
- Exécution sur CPU pour économiser la mémoire GPU
|
||||
|
||||
### Stockage des Données
|
||||
|
||||
Les embeddings et images de référence sont stockés dans :
|
||||
```
|
||||
data/visual_embeddings/
|
||||
├── emb_step_xxx_YYYYMMDD_HHMMSS.npy # Embedding numpy
|
||||
└── emb_step_xxx_YYYYMMDD_HHMMSS_ref.png # Image de référence
|
||||
```
|
||||
|
||||
## Intégration Frontend
|
||||
|
||||
Le composant `VisualSelector` (`visual_workflow_builder/frontend/src/components/VisualSelector/index.tsx`) utilise ces endpoints pour :
|
||||
|
||||
1. **Étape 1 - Capture** : Appel à `/api/screen-capture`
|
||||
2. **Étape 2 - Sélection** : Interface canvas pour sélectionner une zone
|
||||
3. **Étape 3 - Confirmation** : Appel à `/api/visual-embedding` pour créer l'embedding
|
||||
|
||||
## Tests
|
||||
|
||||
Les tests sont disponibles dans :
|
||||
- `tests/integration/test_vwb_screen_capture_api.py`
|
||||
|
||||
### Exécution des Tests
|
||||
|
||||
```bash
|
||||
python3 -c "
|
||||
import sys
|
||||
sys.path.insert(0, '.')
|
||||
sys.path.insert(0, 'visual_workflow_builder/backend')
|
||||
from app_lightweight import capture_screen_to_base64, create_visual_embedding
|
||||
|
||||
# Test capture
|
||||
result = capture_screen_to_base64()
|
||||
print(f'Capture: {result[\"success\"]}')
|
||||
|
||||
# Test embedding
|
||||
if result['success']:
|
||||
bbox = {'x': 100, 'y': 100, 'width': 200, 'height': 100}
|
||||
emb = create_visual_embedding(result['screenshot'], bbox, 'test')
|
||||
print(f'Embedding: {emb[\"success\"]}')
|
||||
"
|
||||
```
|
||||
|
||||
## Résultats de Validation
|
||||
|
||||
- ✅ Capture d'écran fonctionnelle (1920x1080)
|
||||
- ✅ Création d'embeddings CLIP (dimension 512)
|
||||
- ✅ Sauvegarde des embeddings en fichiers .npy
|
||||
- ✅ Sauvegarde des images de référence en PNG
|
||||
- ✅ Intégration avec le frontend VisualSelector
|
||||
|
||||
## Prochaines Étapes
|
||||
|
||||
1. Tests d'intégration avec le frontend en conditions réelles
|
||||
2. Optimisation du temps de chargement du modèle CLIP
|
||||
3. Ajout de la recherche par similarité dans les embeddings existants

Cette version évite les imports lourds et les dépendances optionnelles.
|
||||
|
||||
Fonctionnalités :
|
||||
- API REST pour la gestion des workflows
|
||||
- Capture d'écran via ScreenCapturer (core/capture)
|
