Q: What is lidar technology?

A: Lidar, which stands for Light Detection and Ranging, is a laser-based sensing technology that precisely measures distance and shape by illuminating targets with laser light and analyzing the reflected pulses. This creates detailed 3D maps and models.

Q: How does lidar work for autonomous vehicles?

A: Autonomous vehicles use lidar technology sensors to detect surrounding objects up to 200 meters away. The lidar maps allow AVs to locate themselves precisely and identify hazards and obstacles. This enables safe, reliable autonomous navigation.

Q: Is lidar better than radar?

A: Lidar is better than radar for mapping detailed 3D environments because its laser pulses provide much higher resolution with accuracy down to a few centimeters. Lidar technology also performs better than radar in poor weather conditions.

Q: Why is lidar so expensive?

A: Early lidar used complex mechanical components like spinning mirrors or motors, which made these systems extremely costly. Newer solid-state lidar technology removes these parts to lower size and price. Mass manufacturing and simplifying designs will continue to reduce lidar costs.

Q: How do self-driving cars see?

A: Self-driving car perception systems combine lidar’s 3D mapping with radar, cameras, and AI software. This sensor fusion allows AVs to accurately understand their surroundings for safe autonomous operation.
