Surveying - Unmanned Laserscanning

We are one of the first European companies to invest in this tried and tested (yet until recently too heavy) technology for UAVs and we can now provide so-called “unmanned scanning” services. Use is made of a miniature sensor by the leading producer in the airborne laser scanning field and thus a high level of quality is guaranteed!

Riegl miniVUX-1

The first miniVUX system with Applanix APX-20-IMU to be delivered worldwide is a proud part of our fleet! The smallest and lightest waveform LiDAR system in the world (from Austrian laser scan specialists Riegl) can record up to 5 points per pulse, which permits more than simply a first-pulse-last-pulse analysis! The interplay between scanner and IMU allows for an improvement in trajectory due to feedback from the scans, which in turn produces recognisably better results than from other flying scanner systems.

Riegl miniVUX-1DL

The Riegl MiniVUX - 1 DL is based on the MiniVUX - 1, but has a different mirror system. "DL" stands for "downward looking", and thus describes the scanner's field of view. The scanner measures the terrain in a conical movement with an angle of 46°, making it perfect for corridor mapping and inspection flights over power lines. An Applanix APX-20 is also installed in this scanner, as the combination has already proven itself in the MiniVUX - 1.

Soleon LasCO x8flat

This large octocopter from South Tyrolean multicopter makers Soleon was custom designed, printed, milled and built according to our requirements for payload, mountain-focus and flight planning. Coming in at 15kg take-off weight, it can carry 5 kg of load through the air for over 20 minutes.

DJI Matrice 600 Pro

The DJI Matrice 600 Pro or also M600 Pro is a hexacopter of the international manufacturer DJI. Therefore the copter and its wear parts are available worldwide. The drone stands out for its excellent flight characteristics and smooth directional changes.

Helicopters

For very extensive project areas over 300 - 400 ha we use a helicopter for reasons of economy and time. The economic advantage of helicopter surveying lies in the flight time, flight speed and flight altitude. Thus more area can be covered in less time. However, it can be assumed that the point cloud has a lower point density than a point cloud recorded with UAV. The laser scanners used are special laser scanners which have been developed for traditional aircraft such as helicopters. 

 

UAV planner 3D

The problem with surveying flights is that it is relatively easy to plan such a mission in 2D: the overlap in the X and Y directions are at hand and the altitude remains constant. On flat land, this represents a simple exercise in geometry.

However the Earth is unfortunately not always as flat as the plains of Northern Germany. For precisely this reason, we have developed a tool with which you can also create plans for flights over hilly and mountainous areas.

The aim was to keep the distance to the object to be measured constant, regardless of whether the inclination of the surface is 0° or 90°. This is the only way to ensure that the overlap and ground resolution remain constant during the entire automatic flight.
