LiDAR
Definition
LiDAR measures distances with light pulses and generates spatial point clouds or depth information from them.
A sensor emits laser pulses and measures the reflection time. From this, geometry and the environment can be captured three-dimensionally.
Simply explained
How to build a 3D map simultaneously with many laser distance meters.
Why it matters in practice
Relevant for robotics, surveying, autonomous systems, and digital twins.
Example from business
A system scans its environment to detect obstacles or object positions.
Limits and pitfalls
- Equate LiDAR with camera; ignore measurement errors caused by material/weather; use point cloud without calibration.
Origin & history
Laser ranging has developed since the 1960s; modern LiDAR systems combine high measurement rates with 3D reconstruction.
Use in mid-sized companies
- Possible application in SMEs: Evaluate surveying or automation projects with spatial sensor data.
Frequently asked questions
Is LiDAR a camera?
