🚀 Air Defense System Simulation (C++ & OpenCV)

📜 Overview

This project is a Real-time Air Defense System Simulation built from scratch using C++ and OpenCV. It transforms a standard webcam feed into a military-grade Heads-Up Display (HUD).

The system uses Computer Vision algorithms to detect and track enemy targets (objects of a specific color) and features a fully functional Missile Guidance System based on vector mathematics.

✨ Key Features

• 🎯 Computer Vision Tracking:
  • Utilizes HSV Color Space for robust object detection (immune to lighting changes).
  • Noise reduction using morphological operations (Erosion/Dilation).
  • Contour analysis to identify the largest threat.
• 🖥️ Military HUD Interface:
  • Unit 777 Egyptian branding theme.
  • Dynamic Compass Tape & Altitude Indicator.
  • Active Scanning Radar visualization.
  • Real-time system logs and status updates.
• 🚀 Missile Physics & Logic:
  • Guidance Algorithm: Uses Vector Math to calculate the trajectory towards the moving target frame-by-frame.
  • Particle System: Simulates missile smoke trails and impact explosions.
• 👁️ Thermal Vision Mode:
  • Simulated IR/Thermal view for the AI processing layer.

🛠️ Tech Stack

• Language: C++ (Standard 17)
• Library: OpenCV 4.x
• Build System: CMake

⚙️ Installation & Setup

1. Prerequisites:

   • C++ Compiler (MSVC or MinGW).
   • CMake installed.
   • OpenCV installed and configured in your system Path.

2. Clone the Repository:

   git clone [https://github.com/ahmedfox1/-Air-Defense-System-Simulation-C-OpenCV-.git](https://github.com/ahmedfox1/-Air-Defense-System-Simulation-C-OpenCV-.git)
   cd Air-Defense-System

3. Build with CMake:

   • Open the project in CLion or Visual Studio.
   • Update the CMakeLists.txt file to point to your OpenCV build directory if necessary:

     set(OpenCV_DIR "C:/path/to/opencv/build")

   • Build and Run.

🎮 How to Use

1. Launch the System: Run the compiled executable.
2. Acquire Target: Hold a Blue Object (or the color you configured) in front of the camera.
3. Wait for Lock: The system will draw a bounding box and display LOCK.
4. Fire: Press SPACE to launch a missile.
5. Impact: Watch the missile track the target and explode upon impact.
6. Exit: Press ESC.

🧠 How It Works (The Math)

1. The Vision Pipeline

We convert the frame from BGR to HSV to isolate the target's color. A binary mask is created, processed to remove noise, and then contours are analyzed to find the target's center (x, y).

2. Missile Guidance (Vector Math)

When the missile is fired, we calculate the direction vector in every frame:

Point diff = targetPos - missilePos; // Vector from missile to target
missilePos += diff * SPEED_FACTOR;   // Move missile along that vector
