Laser Scanning Technology

What is Laser Scanning Technology?

Laser scanning technology in construction is used to provide a high accuracy survey of a building or land. Also known as High Definition Surveying (HDS) it uses laser beams to capture all the detail of a building and produce a 360 degree photo or plan.

It works by shining the laser onto the object and then collecting the data from another sensor such as a camera. This creates point cloud data with millions of 3D XYZ coordinates that can be placed together to build an accurate survey and model of the building.

The History of 3D Scanning Technology

The application of 3D laser scanning technology has been around for longer than you may think – it first began in the sixties. Of course, this was a much longer process than today and used a combination of cameras, projectors and lights to produce the building survey.

In the eighties, this upgraded to the use of laser beams with the introduction of LiDar systems. This used the lasers and shadowing to produce data of objects and their surfaces.

Now, laser scanning technology has come very far and uses a combination of laser beams, advanced sensors, GPS, Inertial Measurement Units (IMU) as well as receiver electronics and photo detectors to build a highly accurate image – so accurate in fact it is to 0.1mm or better.

The Rising Popularity of Laser Scanning Technology in Construction

3D Laser scanning technology has become increasingly popular for construction projects due its overwhelming accuracy and speed to provide a 360 degree photo of a building or landscape aiding architects and engineers in being able to accurately plan their approach to the work.

Because the point cloud data produces millions of 3D coordinates, they can use the survey to pinpoint areas to the nearest 0.1mm and as many of us know, good construction relies on accuracy.

Laser scanning technology can be used on repairs or extensions to existing buildings or when constructing on existing green or brown belt land. It is able to provide an accurate and detailed survey to identify the existing conditions of the land and illustrate any building issues you may face during construction and likely obstacles you could face.

By having an accurate survey, you can identify these issues early before building begins, allowing you to work out how to work round any issues before construction begins and saving costly repairs or last minute fixes later into the process.

We’re on hand to answer your questions and work with you to produce an accurate survey for your next project.

How does laser scanning technology work?

Laser scanning works by using laser beams, which then bounce off the building and are picked up by another sensor. This creates point cloud data for every point of the surface which in turn creates millions of tiny EYZ coordinates that can be put together by software to create a 3D image of the building.

This can be used to create a 3D model which we can produce for you in-house with our range of model options to choose from which are ideal for displaying your building plans to clients, employees and the general public.

Laser scanning technology is the most accurate survey measure and can produce detailed data on objects, surfaces, buildings and landscapes. It has an accuracy level of 0.1mm or better, so you can be confident you are seeing every aspect of your project site in minute detail, so you can accurately plan your approach to the tiniest detail.

As well as being extremely accurate, it is also the quickest land surveying method, plotting millions of data points in seconds, reducing the time and resources need to produce a site survey.

As well as 3D laser scanning surveys and 3D models, we also provide a range of other survey options for clients such as drone, topographic and house surveys.

Our topographic surveys use GPS to locate fixed points on an area of land to use as reference markers and demonstrate the height and base of an area to produce a topographic map of the land.

Drone surveys are ideal when you need to collect data from land that is difficult or dangerous to reach.

House surveys are usually the type of building survey most of us our familiar with and are an essential requirement of house buyers to ensure the property they are buying has no structural issues or problems that could become costly down the line to repair.
