  • Enables real-time perception and navigation
  • Improves safety and efficiency
  • Automates complex tasks in dynamic environments

2. Computer Vision in Autonomous Systems

Computer vision, powered by convolutional neural networks (CNNs), allows autonomous systems to interpret visual data from cameras and sensors.

  • Object Detection: Identifying obstacles, pedestrians, or traffic signs.
  • Image Segmentation: Separating objects in a scene for precise analysis.
import tensorflow as tf from tensorflow.keras import layers # Example: CNN for Object Detection model = tf.keras.Sequential([ layers.Conv2D(32, (3, 3), activation='relu', input_shape=(128, 128, 3)), layers.MaxPooling2D((2, 2)), layers.Conv2D(64, (3, 3), activation='relu'), layers.Flatten(), layers.Dense(10, activation='softmax') ]) model.summary()

3. Path Planning and Navigation

AI algorithms, such as reinforcement learning and graph-based methods, enable autonomous systems to plan optimal paths in complex environments.

  • Reinforcement Learning: Learning optimal navigation policies.
  • A* Algorithm: Finding the shortest path in a graph.
πŸ’‘ Pro Tip: Combine sensor data (e.g., LIDAR, cameras) with AI models for robust path planning.

4. Decision-Making with AI

AI enables autonomous systems to make real-time decisions, such as braking or turning, based on sensor inputs and environmental analysis.

  • Behavioral Prediction: Anticipating pedestrian or vehicle movements.
  • Control Systems: Adjusting speed or direction dynamically.

5. Practical Examples

Here’s an example of a CNN for classifying road signs in autonomous vehicles, using a simplified dataset for demonstration.
