## 🚀 Getting Started


### One-Minute Setup (Docker)


```bash

git clone https://github.com/ravibeta/dvsa-api.git

cd dvsa-api

docker-compose up

# API live at http://localhost:8000

# UI live at http://localhost:3000

```


### Integrate into Your AI Application


**Option 1: Call the REST API from your LLM agent**


```python

# Python agent example (Langchain/AutoGen)

import requests


DVSA_API = "http://localhost:8000/api"


def analyze_drone_footage(video_id: str, model: str = "yolov8") -> dict:

    """Run object detection on a drone video."""

    resp = requests.post(

        f"{DVSA_API}/analytics/videos/{video_id}/run",

        json={"routines": [model], "frame_step": 30, "max_frames": 300}

    )

    resp.raise_for_status()

    return resp.json() # Detections with bbox, labels, confidence scores


# Use in your ReAct / agent loop

def agent_action(video_id: str):

    detections = analyze_drone_footage(video_id)

    summary = f"Found {len(detections)} objects: {detections['summary']}"

    return summary # Pass to LLM as observation

```


**Option 2: Embed DVSA as a Python library**


```python

from apps.analytics.routines import run_frame_routine

from apps.analytics.models import Video

import cv2


# Load a video from the database

video = Video.objects.get(id=video_id)

frame = cv2.imread(video.file_path)


# Run any registered detector synchronously

result = run_frame_routine("custom_onnx_detection", frame)

print(result) # {"label": "vehicle", "score": 0.92, "bbox": [x, y, w, h], ...}

```


**Option 3: Plug into your data pipeline**


```python

# Async Celery task for batch processing

from dvsa_api.analytics.tasks import run_video_analysis


# Queue analysis for 1000 videos

for video_id in video_ids:

    run_video_analysis.delay(

        video_id=video_id,

        routines=["yolov8_coco", "crowd_estimation"],

        frame_step=60

    )


# Results automatically persisted to PostgreSQL

# Query via REST API: GET /api/analytics/videos/{video_id}/results

```

## 🏗️ Architecture & Design Philosophy


### Full-Stack, Production-Ready


**Backend (dvsa-api)** — Python 97.8%

- **Framework**: Django 5.2 + Django REST Framework 3.16

- **Task Queue**: Celery + Redis (async video processing)

- **Database**: PostgreSQL (video metadata, detection results, geospatial queries)

- **Auth**: Token-based JWT for API security

- **Deployment**: Docker, Kubernetes-ready


**Frontend (dvsa-ui)** — TypeScript 78.2%

- **React 18** with modern hooks & TypeScript

- **Styling**: Tailwind CSS for professional, responsive UI

- **State Management**: Built for real-time analytics dashboards

- **Features**: Dark mode, role-based access, real-time result streaming


### Key Design Principles


1. **Modularity**: Each detection model (YOLO, Faster R-CNN, custom ONNX) plugs in via a common interface.

2. **Extensibility**: Add new analytics routines (crowd counting, vehicle tracking, anomaly detection) without touching core code.

3. **Testability**: Mocked runtimes in CI/CD; test detection logic without GPU or model weights.

4. **Performance**: Intelligent frame sampling, tiling for high-res images, async background workers.

5. **Portability**: Ship models as ONNX (cross-platform, no PyTorch/TensorFlow dependency at runtime).


---


## 🔧 Core Features


### 1. **Multi-Format Model Support**


Run any detection model seamlessly—no boilerplate per format:


| Format | Support | Example |

|--------|---------|---------|

| **Ultralytics YOLO** | ✅ v5, v8 (`.pt`, ONNX) | `ultralytics-yolov8-coco` |

| **ONNX** | ✅ Native | Custom LandingLens, Azure Custom Vision, MMDetection exports |

| **PyTorch (TorchScript)** | ✅ `.pt` traced models | Faster R-CNN, DOTA, DIOR detectors |

| **TensorFlow** | ✅ Via ONNX export | MobileNet, EfficientDet |


```python

from custom_models import ModelSelector, get_detector


selector = ModelSelector.default() # Loads bundled catalog

spec = selector.select(

    task="detection",

    classes=["person", "vehicle"],

    altitude="high", # Hints toward tiling-capable models

    resolution=(3840, 2160), # Recommends 4K-friendly detectors

)

detector = get_detector(spec).load()

detections = detector.infer(frame) # Same interface for all formats

```


### 2. **Intelligent Model Selection**


Don't guess—let DVSA recommend the right model for your use case:


- **VisDrone YOLOv8x** — Tiny objects at altitude; optimized for drone datasets.

- **TPH-YOLOv5** — Extreme resolution (VisDrone training). Handles 4K+ with tiling.

- **Faster R-CNN (DOTA)** — High accuracy for geospatial object detection.

- **Ultralytics YOLO (COCO)** — General-purpose; fast, 80 classes.


Swap models in production without code changes—just update config or the UI selector.


### 3. **High-Resolution Video Handling**


Process 4K, 8K, and beyond with automatic tiling & NMS:


```python

ModelConfig(

    onnx_path="model.onnx",

    input_size=(640, 640),

    tile_size=(1024, 1024), # Automatic tiling for large frames

    tile_overlap=0.2, # 20% overlap → post-process with NMS

)

```


No more out-of-memory crashes or missed small objects in high-res footage.


### 4. **Curated Model Catalog**


Metadata-first design: catalog ships model *info* (format, input size, training dataset), not weights. Download weights once from your source, then use the same API:


```json

[

  {

    "id": "visdrone-yolov8x",

    "format": "yolo",

    "source_url": "https://huggingface.co/dronefreak/visdrone-yolov8x",

    "artifact_filename": "visdrone-yolov8x.pt",

    "input_size": [640, 640],

    "training_dataset": "VisDrone (480K images)",

    "best_for": "aerial detection at altitude"

  },

  {

    "id": "tph-yolov5",

    "format": "yolo",

    "source_url": "https://github.com/cv516Buaa/tph-yolov5",

    "artifact_filename": "tph-yolov5.pt",

    "tile_size": [1024, 1024],

    "training_dataset": "VisDrone (extreme resolution)",

    "best_for": "4K+ drone footage"

  }

]

```


### 5. **RESTful Analytics API**


Standard HTTP semantics; works with any client (Python, Node, Go, etc.):


```bash

# Upload video

curl -X POST http://localhost:8000/api/videos/upload \

  -F "file=@footage.mp4"


# List available analytics routines

curl http://localhost:8000/api/analytics/routines


# Run analysis

curl -X POST http://localhost:8000/api/analytics/videos/{id}/run \

  -H "Content-Type: application/json" \

  -d '{

    "routines": ["yolov8_coco", "crowd_estimation"],

    "frame_step": 30,

    "max_frames": 300

  }'


# Fetch results

curl http://localhost:8000/api/analytics/videos/{id}/results

```


### 6. **Geospatial & Temporal Queries**


Seamlessly query detections by location, time, and class:


```python

from apps.analytics.models import Detection


# Find all "vehicle" detections in a region

detections = Detection.objects.filter(

    video__geom__intersects=region_polygon,

    label="vehicle",

    timestamp__gte=start_time,

    confidence__gte=0.85

)

```


Perfect for context-aware retrieval in RAG pipelines.


### 7. **Async, Scalable Processing**


Queue videos for batch analysis; results streamed as they complete:


```python

# Celery task—scales with your Redis/RabbitMQ

from dvsa_api.analytics.tasks import run_video_analysis


for video in large_dataset:

    run_video_analysis.delay(video.id, routines=["yolov8_coco"])


# Client polls: GET /api/analytics/videos/{id}/status

# Or use websocket for real-time updates

```


---


## 🎓 Integration Patterns for AI/LLM Applications


### Pattern 1: RAG + Drone Detections


```python

from langchain.vectorstores import Chroma

from langchain.embeddings import OpenAIEmbeddings


# Every detection → structured observation

def extract_observations(video_id: str) -> list[str]:

    detections = dvsa_api.analyze_video(video_id)

    observations = [

        f"At {d['timestamp']}, detected {d['label']} "

        f"(confidence {d['score']:.2f}) at {d['bbox']}"

        for d in detections

    ]

    return observations


# Embed observations into vector DB

vectorstore = Chroma.from_texts(

    observations,

    embedding_function=OpenAIEmbeddings(),

    collection_name="drone_detections"

)


# Retrieve relevant observations for LLM context

def query_observations(question: str) -> str:

    relevant = vectorstore.similarity_search(question, k=5)

    return "\n".join([doc.page_content for doc in relevant])


# Use in agent

agent_response = llm.call(

    f"Based on these drone observations: {query_observations('vehicles near the facility')}, "

    "what's the traffic situation?"

)

```


### Pattern 2: ReAct Agent with Drone Vision


```python

from react_agent import ReActAgent, Tool


class DroneAnalysisTool(Tool):

    """Tool for agents to analyze drone footage."""

    

    def __init__(self, dvsa_base_url: str):

        self.dvsa = DVSAClient(dvsa_base_url)

    

    def __call__(self, video_id: str, analysis_type: str) -> str:

        """

        Run drone video analysis.

        Args:

            video_id: ID of the drone video

            analysis_type: 'detection', 'crowd', 'tracking'

        """

        result = self.dvsa.run_analysis(video_id, analysis_type)

        return f"Analysis complete: {result['summary']}"


# Register tool with agent

agent = ReActAgent(

    tools=[

        DroneAnalysisTool("http://localhost:8000"),

        # ... other tools (web search, database query, etc.)

    ]

)


# Agent loop with vision

thought = "I need to see what's happening at the facility."

action = agent.decide_action(thought)

# → Tool: DroneAnalysisTool(video_id=123, analysis_type="detection")

observation = agent.take_action(action)

# → "Analysis complete: Found 15 vehicles, 32 people; alert threshold exceeded"

```


### Pattern 3: Multi-Modal LLM Context


```python

from openai import OpenAI


# Use DVSA to structure drone observations for GPT-4V

def enrich_with_drone_context(query: str, video_id: str) -> str:

    # Get detections

    detections = dvsa_api.analyze_video(video_id)

    

    # Fetch video frame (or use DVSA's frame endpoint)

    frame = dvsa_api.get_frame(video_id, frame_num=0)

    

    # Combine structured data + image for GPT-4V

    client = OpenAI()

    response = client.chat.completions.create(

        model="gpt-4-vision-preview",

        messages=[

            {

                "role": "user",

                "content": [

                    {

                        "type": "text",

                        "text": f"Detections: {detections}\n\nQuestion: {query}"

                    },

                    {

                        "type": "image_url",

                        "image_url": {

                            "url": f"data:image/jpeg;base64,{frame_base64}"

                        }

                    }

                ]

            }

        ]

    )

    return response.choices[0].message.content

```

## 💡 Why DVSA Will Become the Standard


1. **Purpose-Built for Drones**: Most vision libraries (MediaPipe, OpenCV, PyTorch) treat drone footage as generic video. DVSA understands altitude, tiling, geospatial context, and real-time cons[...]


2. **Bridges AI & Vision**: Unlike closed-source commercial offerings, DVSA exposes clean Python/REST interfaces that LLM agents and RAG systems can reason over. It's not a black box—it's a bui[...]


3. **Production-Ready**: Eschews toy examples. Includes auth, async workers, logging, tests, deployment manifests, and error handling from day one.


4. **Vendor Neutral**: Run any model (YOLO, R-CNN, custom). Ship as ONNX for portability. Don't lock in to a single platform.


5. **Community Momentum**: Open-source from day one. Low barrier to contribution. Aligned with trends in AI (LLM-centric architectures, multi-modal reasoning, geospatial intelligence).


6. **Extensible Architecture**: New analytics routine? New deployment target? Add it without forking. The plugin system is clean and proven.

    input_size=(640, 640),

    tile_size=(1024, 1024), # Automatic tiling for large frames

    tile_overlap=0.2, # 20% overlap → post-process with NMS

)

```


No more out-of-memory crashes or missed small objects in high-res footage.


### 4. **Curated Model Catalog**


Metadata-first design: catalog ships model *info* (format, input size, training dataset), not weights. Download weights once from your source, then use the same API:


```json

[

  {

    "id": "visdrone-yolov8x",

    "format": "yolo",

    "source_url": "https://huggingface.co/dronefreak/visdrone-yolov8x",

    "artifact_filename": "visdrone-yolov8x.pt",

    "input_size": [640, 640],

    "training_dataset": "VisDrone (480K images)",

    "best_for": "aerial detection at altitude"

  },

  {

    "id": "tph-yolov5",

    "format": "yolo",

    "source_url": "https://github.com/cv516Buaa/tph-yolov5",

    "artifact_filename": "tph-yolov5.pt",

    "tile_size": [1024, 1024],

    "training_dataset": "VisDrone (extreme resolution)",

    "best_for": "4K+ drone footage"

  }

]

```


### 5. **RESTful Analytics API**


Standard HTTP semantics; works with any client (Python, Node, Go, etc.):


```bash

# Upload video

curl -X POST http://localhost:8000/api/videos/upload \

  -F "file=@footage.mp4"


# List available analytics routines

curl http://localhost:8000/api/analytics/routines


# Run analysis

curl -X POST http://localhost:8000/api/analytics/videos/{id}/run \

  -H "Content-Type: application/json" \

  -d '{

    "routines": ["yolov8_coco", "crowd_estimation"],

    "frame_step": 30,

    "max_frames": 300

  }'


# Fetch results

curl http://localhost:8000/api/analytics/videos/{id}/results

```


### 6. **Geospatial & Temporal Queries**


Seamlessly query detections by location, time, and class:


```python

from apps.analytics.models import Detection


# Find all "vehicle" detections in a region

detections = Detection.objects.filter(

    video__geom__intersects=region_polygon,

    label="vehicle",

    timestamp__gte=start_time,

    confidence__gte=0.85

)

```


Perfect for context-aware retrieval in RAG pipelines.


### 7. **Async, Scalable Processing**


Queue videos for batch analysis; results streamed as they complete:


```python

# Celery task—scales with your Redis/RabbitMQ

from dvsa_api.analytics.tasks import run_video_analysis


for video in large_dataset:

    run_video_analysis.delay(video.id, routines=["yolov8_coco"])


# Client polls: GET /api/analytics/videos/{id}/status

# Or use websocket for real-time updates

```


---


## 🎓 Integration Patterns for AI/LLM Applications


### Pattern 1: RAG + Drone Detections


```python

from langchain.vectorstores import Chroma

from langchain.embeddings import OpenAIEmbeddings


# Every detection → structured observation

def extract_observations(video_id: str) -> list[str]:

    detections = dvsa_api.analyze_video(video_id)

    observations = [

        f"At {d['timestamp']}, detected {d['label']} "

        f"(confidence {d['score']:.2f}) at {d['bbox']}"

        for d in detections

    ]

    return observations


# Embed observations into vector DB

vectorstore = Chroma.from_texts(

    observations,

    embedding_function=OpenAIEmbeddings(),

    collection_name="drone_detections"

)


# Retrieve relevant observations for LLM context

def query_observations(question: str) -> str:

    relevant = vectorstore.similarity_search(question, k=5)

    return "\n".join([doc.page_content for doc in relevant])


# Use in agent

agent_response = llm.call(

    f"Based on these drone observations: {query_observations('vehicles near the facility')}, "

    "what's the traffic situation?"

)

```


### Pattern 2: ReAct Agent with Drone Vision


```python

from react_agent import ReActAgent, Tool


class DroneAnalysisTool(Tool):

    """Tool for agents to analyze drone footage."""

    

    def __init__(self, dvsa_base_url: str):

        self.dvsa = DVSAClient(dvsa_base_url)

    

    def __call__(self, video_id: str, analysis_type: str) -> str:

        """

        Run drone video analysis.

        Args:

            video_id: ID of the drone video

            analysis_type: 'detection', 'crowd', 'tracking'

        """

        result = self.dvsa.run_analysis(video_id, analysis_type)

        return f"Analysis complete: {result['summary']}"


# Register tool with agent

agent = ReActAgent(

    tools=[

        DroneAnalysisTool("http://localhost:8000"),

        # ... other tools (web search, database query, etc.)

    ]

)


# Agent loop with vision

thought = "I need to see what's happening at the facility."

action = agent.decide_action(thought)

# → Tool: DroneAnalysisTool(video_id=123, analysis_type="detection")

observation = agent.take_action(action)

# → "Analysis complete: Found 15 vehicles, 32 people; alert threshold exceeded"

```


### Pattern 3: Multi-Modal LLM Context


```python

from openai import OpenAI


# Use DVSA to structure drone observations for GPT-4V

def enrich_with_drone_context(query: str, video_id: str) -> str:

    # Get detections

    detections = dvsa_api.analyze_video(video_id)

    

    # Fetch video frame (or use DVSA's frame endpoint)

    frame = dvsa_api.get_frame(video_id, frame_num=0)

    

    # Combine structured data + image for GPT-4V

    client = OpenAI()

    response = client.chat.completions.create(

        model="gpt-4-vision-preview",

        messages=[

            {

                "role": "user",

                "content": [

                    {

                        "type": "text",

                        "text": f"Detections: {detections}\n\nQuestion: {query}"

                    },

                    {

                        "type": "image_url",

                        "image_url": {

                            "url": f"data:image/jpeg;base64,{frame_base64}"

                        }

                    }

                ]

            }

        ]

    )

    return response.choices[0].message.content

```

## 💡 Why DVSA Will Become the Standard


1. **Purpose-Built for Drones**: Most vision libraries (MediaPipe, OpenCV, PyTorch) treat drone footage as generic video. DVSA understands altitude, tiling, geospatial context, and real-time cons[...]


2. **Bridges AI & Vision**: Unlike closed-source commercial offerings, DVSA exposes clean Python/REST interfaces that LLM agents and RAG systems can reason over. It's not a black box—it's a bui[...]


3. **Production-Ready**: Eschews toy examples. Includes auth, async workers, logging, tests, deployment manifests, and error handling from day one.


4. **Vendor Neutral**: Run any model (YOLO, R-CNN, custom). Ship as ONNX for portability. Don't lock in to a single platform.


5. **Community Momentum**: Open-source from day one. Low barrier to contribution. Aligned with trends in AI (LLM-centric architectures, multi-modal reasoning, geospatial intelligence).


6. **Extensible Architecture**: New analytics routine? New deployment target? Add it without forking. The plugin system is clean and proven.
