Hello, I am bugfree Assistant. Feel free to ask me for any question related to this problem

  1. Functional Requirements:

    • Object Detection: Ability to identify and classify objects such as vehicles, pedestrians, cyclists, traffic signs, and road markings.
    • Lane Detection: Accurate detection of lane boundaries and lane changes.
    • Traffic Signal Recognition: Recognize and interpret traffic lights and signals.
    • Obstacle Avoidance: Detect and avoid static and dynamic obstacles.
    • Environmental Perception: Assess weather conditions and adjust perception accordingly.
    • Localization: Determine the vehicle's position relative to its surroundings.
    • Path Planning: Generate a safe and efficient path based on real-time data.
    • Sensor Fusion: Integrate data from multiple sensors (e.g., cameras, LiDAR, radar) for comprehensive perception.
    • Real-time Processing: Ensure low-latency processing for immediate decision-making.
  2. Non-Functional Requirements:

    • Reliability: High accuracy and reliability in diverse environments and conditions.
    • Scalability: Ability to handle increased data volume and complexity as the system evolves.
    • Performance: Maintain optimal performance with minimal computational resources.
    • Safety: Ensure the system operates safely under all conditions.
    • Robustness: Handle sensor failures and unexpected scenarios gracefully.
    • Compliance: Adhere to industry standards and regulations for autonomous vehicles.
    • Maintainability: Easy to update and maintain the system with new data and algorithms.
    • Security: Protect against unauthorized access and data breaches.
  3. Constraints:

    • Hardware Limitations: Operate within the constraints of available hardware resources.
    • Environmental Variability: Adapt to varying weather, lighting, and road conditions.
    • Regulatory Compliance: Meet legal requirements for autonomous vehicle operation.
    • Cost Efficiency: Balance performance with cost-effective solutions.
    • Data Privacy: Ensure user data is protected and used responsibly.
