EVERYTHING YOU NEED TO KNOW
To meet the needs of designers and architects nowadays, specialists have to continuously improve their skills and methods.
Nowadays, an increasing number of surveyors are using the latest 3D laser scanning technology to create highly accurate plans and elevations of complex buildings and structures.
In this article, we will talk about the main principles, features and advantages of 3D laser scanning.
Different approaches to measured survey
Conducting engineering and geodetic works involves the use of special devices. Lots of cutting-edge technology is used, including specialised optical, electrical and mechanical devices.
One recent invention was the electronic laser reflectorless total station. Such a device has dramatically simplified the implementation of many geodetic tasks and increased the efficiency of work for specialists in the architectural measurements field. In comparison with previously used measuring systems, the appearance of a total station tachometer increased productivity by three times.
Although new devices like the total station tachometer appeared quite recently, soon even they could not cope with all the demands of modern construction. There was a need not only for more accurate coordinate measurements but for the construction of digital models of objects. As it turned out, this requires much more information than standard tachometers can provide. 3D laser scanning of buildings was the optimal solution to the problem. With the new technology it was possible to obtain precise digital models and images of the building.
WHAT IS 3D LASER SCANNING?
3D Laser scanning of objects and buildings is the newest method of obtaining 2D and 3D models of the surrounding space. During the 3D laser scanning process, a points cloud with spatial coordinates is created, which ultimately creates a three-dimensional image. The resulting object model can contain from several thousand to many millions of coordinate points. Measurements are accurate to just one millimetre.
Unlike using a total station, the 3D laser scanning survey method is contactless and as automated as possible. The 3D laser scanning device used at Red Laser Scanning contains a special servo drive that independently rotates the measuring head in the horizontal and vertical planes and records everything in its line of sight up to 130 metres away. The technician no longer needs to press any buttons to turn on the range finder or record the received coordinates, search for the target through the eyepiece of the tachometer etc, eliminating the chance of human error in data collection. All the necessary measurements can be taken from one point without compromising on accuracy.
THE BENEFITS OF USING 3D LASER SURVEYING
3D laser scanning is the ultimate option to save money, time and receive the most detailed and accurate data.
This method of surveying allows us to obtain the maximum amount of data and then create detailed plans or 3D models of a property quickly and easily.
3D laser surveying also makes it possible to electronically store detailed information about any object, be it an architectural monument, residential complex, industrial building, land relief or anything else.
Data produced by our Faro 3D laser scanner is compatible with Autodesk, AVEVA, AutoCAD, Intergraph and other design tools of global manufacturers, making it suitable for a wide range of applications.
