Lidar, on the other hand, are techniques or processes, whereas lasers are devices. A lot of the time, LiDAR technology is used as a 3D laser scanner for buildings in the Architecture, Engineering, and Construction (AEC) industry to scan buildings and then make them available as as-built 3D BIM models based on the scanned data.
Lidar concept
As the name suggests, Lidar stands for light detection and ranging and can also refer to laser scanning or 3D scanning. An effective Lidar mapping system is able to fire up to one million pulses per second for the purpose of mapping.
It is measured how much light will be returned straight to the scanner. After then, the speed of light is used to calculate the distance between two places. As a consequence, plans for rehabilitation or new building are created using computerized representations of the measured locations.
Workflow
1. As light waves are emitted by the Lidar sensor into the building, pulses of light are detected.
2. A pulse is generated by the sensor as soon as it bounces off the building and returns to it.
3. Using a Lidar sensor, the distance traveled by a pulse is calculated by measuring how long it takes for each pulse to return to the Lidar sensor after it has been sent out.
Application
Every stage of the construction process can be addressed with Lidar:
