Computer Vision and Sensors:
- Self-driving cars rely on an array of sensors, including cameras, lidar, radar, and ultrasonic sensors. These sensors capture data about the car’s surroundings.
- Computer vision algorithms process this sensor data to create a detailed map of the environment. They identify objects such as pedestrians, other vehicles, traffic lights, and road signs.
-
Deep Learning and Neural Networks:
- Deep convolutional neural networks (CNNs) process pixel data from visual sensors. They excel at tasks like object detection and lane identification.
- Recurrent neural networks (RNNs) model temporal contexts, such as trajectories, which are crucial for predicting future movements.
- Classic computer vision techniques, like edge detection, enhance feature extraction from sensor data.
-
Reinforcement Learning (RL):
- Startups like Wayve have pioneered the use of RL to teach cars to drive from scratch on real roads. Wayve’s car learned to stay on the road within 20 minutes using trial and error.
- Reinforcement learning trains neural networks by allowing them to explore actions and learn from their consequences. It’s a breakthrough for autonomous driving.
-
Real-Time Decision Making:
- AI algorithms process sensor data in real time to make informed decisions. These decisions include adjusting speed, changing lanes, and avoiding obstacles.
- Neural networks play a crucial role in identifying objects and predicting their behavior, ensuring safe navigation.
Implications:
- Road Safety: As AI systems improve, road safety should surpass human levels. Accidents caused by human error may decrease significantly.
- Efficient Logistics: Self-driving trucks and delivery robots can optimize logistics chains, reducing delivery times and costs.
- Human Supervision: While machines handle driving, humans transition to supervisory roles, monitoring the system.
- Unforeseen Impacts: Transportation touches every aspect of life, so there may be additional implications we haven’t fully explored yet.
Exciting times lie ahead as AI continues to revolutionize transportation!
