Development in Laser Scanning

A laser scanner acts as a survey and monitoring technology which operates based on the measurements of distance obtained between a LiDAR sensor and its surroundings. By using this system it generates a dataset in the form of a point cloud which will show position of each detection point. Inception of laser scanning dates back to 1960s, at this point the equipment was basic which consisted of camera, projectors and lights. In 1985 this was replaced with LiDAR systems which was a more high quality scanner using laser beams and shadowing using to collect data related to objects & surfaces. Today, the laser scanners use ‘point cloud processing software’ which enables them to capture detailed point clouds. In return the dataset creates digital 3D models of the scanned environment.

Application of Laser Scanning

There are various types of industries such as healthcare, manufacturing, entertainment, construction and automobile in which laser scanning services are used. The 3D laser scanning is especially engaged with enhanced technology now more than in the past. These procedures apply laser beams, advanced sensors, global positioning systems, receiver electronics, inertial measurement units & photo detectors. With the usage of all these components, laser scans are able to achieve accurate calculations of surfaces and structures.

Advantages of Laser Scanning

Many relevant organizations use laser scanning over alternative land surveying methods known as photogrammetry, as it brings efficient, high quality & accurate results. Listed below are some of the prominent advantages in using laser scanning technology.

  • Quick collection of data
  • System could even be mounted to vehicles which help immensely when gathering data of roads, railways in a shorter space of time
  • Reduces health and safety risks
  • Ability to survey inaccessible areas
  • Ability to create 3D models from scan data

Services related to Laser Scanning

There is an array of services which could be offered by survey teams using laser scanning.

Future trends in Laser Scanning

Laser scanning is no different to any existing technology in the world. Like any other technology, laser scanning too is subject to evolve in to something better, cheaper and smaller. Technologies reach its maturity with time and more usage. As it happens, it becomes more easily accessible, more elevated and more viable. Similarly laser scanning has also started expanding. It is armed with lot of improvements in point cloud registration and the system is driven by smaller and cheaper scanners. Day by day laser scanning becomes more & more integral in the engineering and construction industry as it is being used for those projects. There is no limit to being creative and innovative, and with the LiDAR becoming a commodity, development possibilities will become even more limitless.
