Introduction to Laser Scanning in Surveying
Understanding Laser Scanning
Historical Context and Evolution of Laser Scanning Technologies
The journey of laser scanning technology in surveying dates back to the 1960s, originating in industrial applications. Sensors evolved over time to become integral tools for geospatial data collection.
Early laser-based distance measuring devices provided limited functionality, primarily aiding in straightforward distance measurements. However, as technology progressed, particularly with the advent of Global Positioning Systems (GPS) in the 1980s, laser scanning emerged as a sophisticated method for capturing high-resolution, three-dimensional spatial data.
By the late 1990s and early 2000s, terrestrial laser scanning (TLS) began to gain traction in civil engineering and architecture, enabling professionals to create detailed three-dimensional models of existing conditions. Airborne laser scanning, or Lidar, soon followed, utilizing flights over vast areas to gather geospatial data for applications such as topographic mapping and forest inventory.
The Science Behind Laser Scanning: How It Works
Laser scanning operates on the principle of pulse echo measurement, which relies on the emission of laser beams toward an object. When the laser pulse hits a surface, a portion of that pulse reflects back to the scanner. By measuring the time it takes for the reflection to return, the distance to the object is calculated based on the speed of light. This process, repeated thousands of times per second, results in a dense collection of data points representing the scanned object’s surface – commonly referred to as a point cloud.
