Light Detection and Ranging (LiDAR) technology is a popular remote sensing method to measure the exact relative distance of objects on the earth’s surface. The technology was conceived in the 1960s and has undergone numerous improvements. This in-depth article from Hokuyo is a guide to selecting the proper lidar sensor for the application that you are considering.

Since its invention, LiDARs have been widely used in forestry, surveying, and mapping. But today, they have turned into a popular unit of autonomous vehicles, robot applications, mining, and infrastructural inspection.

With an array of LiDAR sensors available in the market, featuring different capabilities and specifications, picking the right one for a specific application can get overwhelming.

Read on to find out important considerations when selecting a LiDAR sensor for your application and explore the popular LiDAR classifications to make the right choice.

LiDAR Considerations for Different Applications

Short and Close Range Vs. Long-Range

Long-range LiDARs are expensive and have a range beyond 100 meters. For example, long-range LiDARs are suitable for faster-moving navigating vehicles and detecting objects within mid to long ranges.

A short-range LiDAR detects objects within 25 meters and is well-suited for slow-moving vehicles.

Close-range LiDARs can quickly identify objects in close vicinity. For instance, a close-range LiDAR can identify obstacles near a vehicle’s doors.

Better results are attained when you combine a long or short-range LiDAR with a close-range one.

3D vs. 2D

2D LiDARs identify an object and give the robot or vehicle a ‘something is there’ idea within the range.
