# Experimento-3 - Industrial Machinery Text Detection Dataset

## Dataset Description

This dataset contains **4,237 images** of industrial machinery nameplates with detailed text field annotations for OCR and information extraction tasks. The dataset focuses on extracting key information from equipment nameplates including manufacturer, model, serial numbers, and dates.

## Dataset Summary

- **Task**: Industrial text detection and OCR
- **Domain**: Industrial machinery and equipment
- **Images**: 4,237 total images
- **Annotations**: Bounding boxes for text fields with 8 categories
- **Source**: [Roboflow Universe - Experimento-3](https://universe.roboflow.com/marcos-feria/experimento-3)

## Dataset Structure

### Splits

| Split | Images |
|-------|--------|
| Train | 3,456 |
| Valid | 470 |
| Test | 311 |

### Categories

The dataset includes 8 text field categories commonly found on industrial equipment nameplates:

| ID | Category | Description |
|----|----------|-------------|
| 0 | tipos-pl | Equipment type (unused in annotations) |
| 1 | FABRICANTE | Manufacturer name |
| 2 | FECHA | Date information |
| 3 | MODEL | Model designation |
| 4 | MODELO | Model designation (Spanish) |
| 5 | NUMERO DE SERIE | Serial number (full text) |
| 6 | SN | Serial number (abbreviated) |
| 7 | YEAR | Year information |

## Data Fields

Each example contains:

- `image_id`: Unique image identifier
- `image`: PIL Image of the machinery nameplate
- `width`: Image width in pixels
- `height`: Image height in pixels
- `objects`: Dictionary containing:
  - `bbox`: List of bounding boxes in [x, y, width, height] format (COCO format)
  - `category_id`: List of category IDs (0-7)
  - `category`: List of category names
  - `area`: List of bounding box areas
  - `iscrowd`: List of crowd flags (typically 0)

## Use Cases

This dataset is ideal for:

1. **Industrial OCR Systems**: Extracting text from machinery nameplates
2. **Equipment Inventory Management**: Automated data collection from equipment
3. **Maintenance Planning**: Identifying equipment details for service schedules
4. **Asset Tracking**: Digital cataloging of industrial equipment
5. **Computer Vision Research**: Multi-language text detection in industrial settings

## Data Collection

The images were collected from various industrial machinery and equipment, focusing on nameplates and identification tags. The dataset includes equipment from multiple manufacturers and spans different time periods, providing diverse examples for robust model training.
