Laser scanning allows you to collect a large amount of detailed and accurate 3D information from objects and the surrounding environment in a short time.

Laser scanning is ideal for surveying buildings and structures, industrial facilities, mines, cultural monuments, etc.

The survey result is issued in the form of a point cloud, 3D model, 2D drawings, according to the customer's request. It is also possible to receive a point cloud with color information (RGB). For this, photography must also be performed during the scan. The latter means additional scanning time, the duration of which depends on the equipment used.

Depending on the methodology, laser scanning is classified as:

- static (also terrestrial) laser scanning - the laser scanner is located on a tripod or some other permanent base during the survey

- mobile laser scanning - a laser scanner, usually a system consisting of one or more laser scanners and cameras, is located on a car or other mobile vehicle (train, ATV, boat). Hand-held or backpack-worn laser scanning systems are also classified here.

- aerial laser scanning - a laser scanning system is located on an airplane, helicopter, drone.

The term LIDAR (light detection and ranging) is often used for laser scanners.

Important components of mobile laser scanning systems are also IMU (inertial measurement unit) and GNSS (global navigation satellite system) devices.

REIB Engineering uses static laser scanners Leica RTC360 (2 pcs), Leica BLK360, Riegl VZ-400 and mobile laser scanning systems Riegl VMZ/VZ-400 and Riegl VMX-2HA.

REIB Engineering has been offering mobile laser scanning services since 2016.

Our first mobile laser scanning device, Riegl VMZ/VZ-400, is still in use today. This device is slower than our newer system, but it also allows laser scanning using the Stop&Go method. This scanner has a very long measurement distance - up to 600 meters. The speed of movement when scanning with the Riegl VMZ/VZ-400 system is 30-40 km/h.

In 2024, we acquired the mobile laser scanning device Riegl VMX-2HA. It is significantly more capable than the first device. The Riegl VMX-2HA measures over 3 million points per second with 2 scanners simultaneously and allows measurements to be made at highway speeds, i.e. up to 90 km/h. This device belongs to the top class of MLS technology in the world and has successfully passed the quality tests of the Swedish Road Administration in 2023 and 2024.

Mobile laser scanning technology is ideal for the following tasks:
- surveying roads and streets - topographic maps, 3D models of the ground and surrounding structures, detailed measurements of the road surface (pavement markings, ruts, unevenness, cracks), bases for milling projects, bases for infrastructure projects;
- surveying railways from a moving vehicle on the railway;
- surveying quarries (where it is possible to drive a 4WD car);
- surveying other objects to obtain a topographic map and 3D model, wherever a car can be driven;

Mobile laser scanning allows to significantly increase the performance and safety of field surveying on busy roads and streets, shortening deadlines and ensuring the result in the form of a highly accurate detailed 3D point cloud.

Accuracy is ensured by a number of high-tech accessories in the scanner kit and precise GNSS post-calculation and trajectory calculation. Special software is used for data processing.

The specially trained team of the REIB engineering office is ready to provide high-quality laser scanning services for various purposes, according to the needs of customers. We provide advice, identify the customer's needs in terms of the final result and find the most suitable methodology.

We are ready to provide our services also outside the borders of Estonia. We have performed mobile laser scanning works in Finland, Latvia, Sweden, Germany and the USA.
