How to understand lidar performance Part 1: Resolution and frame rate


Lidar sensor range can be measured in many different ways, making comparisons hard. What are the key variables in range calculations? Why do some sensors see much farther than others? How are range and precision related? What is the difference between range and accuracy?

Join us as we take a deeper look into the performance metrics that are used to assess and compare lidar sensors.

In this series, we walk through a lidar sensor datasheet and explain what the different specs mean—highlighting range, precision, frame rate, resolution, and reliability. We'll explain how we measure these specs, what tradeoffs you may see between the specs, and why they matter for different lidar applications. Then we will walk through a point cloud and show how you can observe the specs in the data itself.
