Static lidar

Static laser scanners are sophisticated instruments that operate much like high-speed total stations and collect lidar point clouds from a static location. Typically, the lidar sensor is mounted on a tripod mount and is a fully portable, laser-based ranging and imaging system.

Lidar technology naturally lends itself to surveying and mapping applications such as construction verification, geological data collection, and mine planning. 

Three types of scanning systems are employed in ground-based lidar:

  • Panoramic scanners rotate 360 degrees around the mounting axis, and scan 180 degrees vertically to provide seamless and total coverage of the surroundings.
  • Single axis scanners also rotate 360 degrees but are limited to a 50-60 vertical swath.
  • Camera scanners point in a fixed direction with limited angular range both horizontally and vertically.

Ground-based lidars can also be classified according to operational range:

  • Short-range systems operate at ranges of 50 – 100 meters with panoramic scanning, and are often used to map building interiors or small objects.
  • Medium range systems operate at distances of 150 – 250 meters, also achieving millimeter accuracies in high definition surveying and 3D modeling applications, such as bridge and dam monitoring.
  • Long range systems can measure at distances of up to one kilometer and are frequently used in open-pit mining and topographic survey applications.
