LiDAR systems: simple principle, impressive accuracy
The Light Detection and Ranging (LiDAR) measurement method is an innovative procedure for digital distance and speed measurement. With these systems from top providers such as Benewake, you can capture individual objects, and processors can create high-resolution 3D maps based on this. The principle is simple, but the technical implementation requires expertise and sophisticated technology:
- The module sends laser impulses in short intervals.
- The LiDAR sensor detects the backscattered light.
- The processor calculates the distance based on the time between sending and receiving.
With LiDAR technology, this process takes place simultaneously at a large number of individual points. The system processes a huge amount of distance data, uses it to reconstruct the recorded objects in detail and displays them in map form.
Wide range of applications for LiDAR sensors
LiDAR technology is currently proving to be a driver of innovation in many fields. The precise measurement of distance and object recognition is the basis for automating tasks in numerous areas.
Examples include:
- autonomous vehicles
- drones and other flying objects
- robots (manufacturing, logistics and more)
- level detection in tanks
- Real-time parking guidance systems (smart parking)
The specific applications differ significantly, and a wide range of LiDAR systems are used accordingly. The requirements profile for the sensors depends on the respective purpose. In autonomous driving, for example, the systems must be able to detect possible obstacles such as other vehicles and pedestrians as well as traffic signs with absolute precision. In smart parking, on the other hand, it is sufficient to know whether the parking space is occupied.
These are the advantages of LiDAR technology
With a LiDAR sensor, you are buying sophisticated technology for distance measurement. In particular, you will benefit from these advantages:
- fast
- precise
- high resolution
- impressive accuracy

How do you use LiDAR for autonomous driving?
LiDAR technology plays a prominent role in partially automated or autonomous driving. Cameras capture the environment and continuously measure the distance to all mobile and immobile objects that could pose a danger to vehicles. They are an integral part of the vehicle's complex hardware and software!
What is the difference between LiDAR and radar?
LiDAR technology is based on reflected light, while radar is based on microwaves. Both technologies have similarities, but LiDAR performs better in comparative tests. This measurement method is faster and more precise, and offers higher resolution.
How does the LiDAR sensor work?
LiDAR technology is based on transmitted light pulses that are reflected by the detected objects. The LiDAR sensordetects the reflected light. By measuring the time of flight, the distance can be determined precisely. The simultaneous measurement at a wide range of individual points makes it possible to display objects exactly as 3D images.
How can I use LiDAR?
There are many different applications for a LiDAR sensor. For example, the precise measurements it provides are invaluable in the automation of processes in manufacturing and logistics. LiDAR technology also supports autonomous driving and intelligent traffic systems with its exact object and speed measurement. This requires the LiDAR sensor to be part of a complex hardware and software system.
