Laser Scanning — An Introduction
Laser scanning is a highly accurate and fast method of creating 3D digital images of the earth’s surface and objects on it.
Perseus are experts in the conduct of terrestrial laser mapping to create robust and practical surveying and monitoring systems. Objects from the small to the large and complex can be rapidly surveyed using LiDAR technology. The resulting geospatial image has extensive applications from engineering, heritage preservation through to security solutions.
Perseus has utilised laser scan technology to design and validate complex security solutions to governments and critical industries. Such is the versatility of the laser scan product that it is increasingly in demand in a wide range of related and practical environments.
Laser Scanning Technology — The benefits
Laser technology is an established process. However, continued developments in technology and mapping means that deploying the system is now a rapid and cost effective process which adds accuracy and value to the development of engineering and geomatic projects.
Laser scanning measures volumes using a pulsed laser controlled by a precise timer which translates the information into range measurements. It is easily deployable and rapidly used. After a survey the data is ‘stitched’ together to form a precise and highly accurate ‘point data cloud’ , which can be viewed through software and can be translated into a wide variety of downstream software formats for further application.
Applications
The applications of this process are considerable. To list a few:
- Surface modeling
- Cavity measurement
- As–built surveys
- Accident reconstruction
- Forensic scene preservation
- Site security surveys
- Extended distance monitoring/change detection
- Heritage archiving
- Chemical contamination scene preservation
- Urban mapping
- Industrial applications
