## 📋 Project Description

**Baseer** is an advanced self-driving system that provides a robust, real-time API for autonomous vehicle control. This Space hosts the FastAPI server that acts as an interface to the fine-tuned **[Interfuser-Baseer-v1](https://huggingface.co/BaseerAI/Interfuser-Baseer-v1)** model.

The system is designed to take a live camera feed and vehicle measurements, process them through the deep learning model, and return actionable control commands and a comprehensive scene analysis.

---

## 🏗️ Architecture

This project follows a decoupled client-server architecture, where the model and the application are managed separately for better modularity and scalability.

## ✨ Key Features

### 🧠 **Advanced Perception Engine**
- **Powered by:** The [Interfuser-Baseer-v1](https://huggingface.co/BaseerAI/Interfuser-Baseer-v1) model.
- **Focus:** High-accuracy traffic object detection and safe waypoint prediction.
- **Scene Analysis:** Real-time assessment of junctions, traffic lights, and stop signs.

### ⚡ **High-Performance API**
- **Framework:** Built with **FastAPI** for high throughput and low latency.
- **Stateful Sessions:** Manages multiple, independent driving sessions, each with its own tracker and controller state.
- **RESTful Interface:** Intuitive and easy-to-use API design.

### 📊 **Comprehensive Outputs**
- **Control Commands:** `steer`, `throttle`, `brake`.
- **Scene Analysis:** Probabilities for junctions, traffic lights, and stop signs.
- **Predicted Waypoints:** The model's intended path for the next 10 steps.
- **Visual Dashboard:** A generated image that provides a complete, human-readable overview of the current state.

## 🚀 How to Use

Interact with the API by making HTTP requests to its endpoints. The typical workflow is to start a session, run steps in a loop, and then end the session.

### 1. Start a New Session
This will initialize a new set of tracker and controller instances on the server.

**Request:**
```bash
curl -X POST "https://BaseerAI-baseer-server.hf.space/start_session"
```

**Example Response:**
```json
{
  "session_id": "a1b2c3d4-e5f6-7890-1234-567890abcdef"
}
```

### 2. Run a Simulation Step

Send the current camera view and vehicle measurements to be processed. The API will return control commands and a full analysis.

**Request:**
```bash
curl -X POST "https://BaseerAI-baseer-server.hf.space/run_step" \
  -H "Content-Type: application/json" \
  -d '{
    "session_id": "a1b2c3d4-e5f6-7890-1234-567890abcdef",
    "image_b64": "your-base64-encoded-bgr-image-string",
    "measurements": {
      "pos_global": [105.0, -20.0],
      "theta": 1.57,
      "speed": 5.5,
      "target_point": [10.0, 0.0]
    }
  }'
```

**Example Response:**
```json
{
  "control_commands": {
    "steer": 0.05,
    "throttle": 0.6,
    "brake": false
  },
  "scene_analysis": {
    "is_junction": 0.02,
    "traffic_light_state": 0.95,
    "stop_sign": 0.01
  },
  "predicted_waypoints": [
    [1.0, 0.05],
    [2.0, 0.06],
    [3.0, 0.07],
    [4.0, 0.07],
    [5.0, 0.08],
    [6.0, 0.08],
    [7.0, 0.09],
    [8.0, 0.09],
    [9.0, 0.10],
    [10.0, 0.10]
  ],
  "dashboard_b64": "a-very-long-base64-string-representing-the-dashboard-image...",
  "reason": "Red Light"
}
```

**Response Fields:**
- **`control_commands`**: The final commands to be applied to the vehicle.
- **`scene_analysis`**: Probabilities for different road hazards. A high `traffic_light_state` value (e.g., > 0.5) indicates a red light.
- **`predicted_waypoints`**: The model's intended path, relative to the vehicle.
- **`dashboard_b64`**: A Base64-encoded JPEG image of the full dashboard view, which can be directly displayed in a client application.
- **`reason`**: A human-readable string explaining the primary reason for the control action (e.g., "Following ID 12", "Red Light", "Cruising").

### 3. End the Session

This will clean up the session data from the server.

**Request:**
```bash
curl -X POST "https://BaseerAI-baseer-server.hf.space/end_session?session_id=a1b2c3d4-e5f6-7890-1234-567890abcdef"
```

**Example Response:**
```json
{
  "message": "Session a1b2c3d4-e5f6-7890-1234-567890abcdef ended."
}
```

## 🎯 Intended Use Cases & Limitations

### ✅ Optimal Use Cases
- Simulating driving in CARLA environments.
- Research in end-to-end autonomous driving.
- Testing perception and control modules in a closed-loop system.
- Real-time object detection and trajectory planning.

### ⚠️ Limitations
- **Simulation-Only:** Trained exclusively on CARLA data. Not suitable for real-world driving.
- **Vision-Based:** Relies on a single front-facing camera and has inherent blind spots.
- **No LiDAR:** Lacks the robustness of sensor fusion in adverse conditions.
