3D-scanning

What exactly is laser scanning?

Laser scanning is a method of capturing positional data of objects in the view of the scanner. It uses a laser pulse to detect surfaces and receives information of their nature when the pulse bounces back. The scanner fires millions of pulses per second and determines the distances to collisions. Other data can be derived from the echoes as well, such as reflectance and the amplitude of the echo.

The scanner processes these collision points and records each one. Several scanning positions’ data can then be combined to form a single 3D picture of the target view.

The resulting point clouds are usually cleaned of unnecessary data such as people and vehicles, depending on the requirements of the client.

The laser used in this process is weak enough to be completely harmless to living creatures and sensitive materials. This is made possible by the sensitivity of the scanner’s optics.

Faster, cost-effectively and more accurately with the new technology

Benefits of the method

 

1. Accurate

Images and data produced with laser scanning is accurate enough to be used as evidence in court. The maximum deviation from real world coordinates is around 0,5 cm, and the laser captures everything it sees, including long blades of leaf and pebbles on the ground.

2. Fast

When compared to traditional methods of surveying and measuring, laser scanning is truly the way of the future. Scanningthe target from a single position takes around one minute and results in millions of points of data.

3. Cost-effective

By using point clouds, extremely accurate drawings and measurements can be produced without ever having to visit the site. With the acquired data you can plan your budget or designs with ease, saving time and money.

Atlastica uses the most advanced laser scanning technology Riegl, which is intended especially for documenting the built environment.

Laser scanning records 20 million points for each scan position with five millimeter precision and in real colors

Get the hardest parts of the building – easily

You might have required additional measurements with total station, measuring tape or laser-utilising distance measuring devices. Using these devices may work, but they are generally very slow when compared to laser scanning. Human error is also more prevalent when using traditional methods of measuring. In practice these methods don’t come even close to the efficiency and precision of laser scanning and point cloud data. Inclined or curved surfaces are especially hard to measure accurately with total station.

One or one million points?

Technological advancement enables the gathering of massive amounts of data quickly. Laser scanning is the future of measuring.

Atlastica records the real world in digital form

Creating detailed and accurate 3D models of areas, buildings or objects with traditional methods is time-consuming and expensive. Atlastica, however, does not use traditional measures for a task that requires something else. We utilise highly advanced laser scanning equipment with which almost any target can be turned into a 3D model. Laser scanning has revolutionised forestry and building industries. Now Atlastica is using this technology to help you digitalise the real world.
