CONSTRUCTION AND INDYSTRY
Both in industry and in construction we often encounter a situation when there is a lack of complete technical documentation reflecting the actual state. It is particularly burdensome during the implementation of the task in a facility with very complicated systems of installations, devices or steel structures. Inventory taking with traditional methods in such conditions is very difficult and sometimes even impossible. It consumes a lot of time and is fraught with considerable measurement errors. The ideal solution in this situation is the use of laser scanning.
Advantages of laser scanning:
- Measurement accuracy up to ± 1mm, impossible to achieve with traditional measuring methods.
- Measurement speed and range. Within a few days, an inventory of a medium-sized industrial plant can be carried out, and the scanning range from one stand reaches 150m, so we can measure hard-to-reach places.
- Obtained point cloud and panoramic views allow you to perform any measurements and reproduce virtually any element within the scanning range while working in the office. This is particularly important when implementing projects in other countries or on other continents.
All this means that during the implementation of projects, not only large ones – industry, but also smaller ones – single-family housing is increasingly using the services of laser scanning companies.
Do you need to make an inventory of a complicated object in a short time?
Or maybe you would like to restore the documentation of an old house in a short time?
Monuments are testimony of a bygone era. Protection and care for the preservation of monuments for future generations are important because of their historical, scientific or artistic value. In order to record the current state of monuments, an inventory is carried out. Currently, laser scanning is increasingly used for this purpose. Importantly, from the point of view of the study of monuments, the use of this method allows you to make measurements without the need for direct contact with the object. It is also worth noting that the laser scanner allows you to inventory of hard-to-reach points, e.g. high towers.
The possibilities offered by the use of laser scanning:
- Preparation of the basic technical documentation of the monument based on a point cloud.
- Analysis of the condition of the historic structure, examination of the verticality of structural elements, e.g. columns, and the shape and structure of existing deformations.
- Examination of the condition of the structure. Determining the type and degree of wear of materials from which the monument is made by interpreting the value of the parameter of the laser beam reflection intensity. This applies, for example, to detect building moisture.
- Detection of existing defects, cracks and precise assessment of their size based on a high resolution point cloud. After modeling the measured defects, you can calculate their volume, measure the width of the cracks and determine their internal structure.
- Laser scanning performed at regular intervals allows detecting emerging deformations and structural damages and testing their progress as a result of adverse external factors.
Depending on the purpose of laser scanning, we offer a point cloud in shades of gray or in color (HDR). Color scanning requires more time during measurement, but it gives you the opportunity to get a realistic texture of the objects.
In addition to raw data in the form of a point cloud, we offer you:
- reconstruction of architectural documentation with drawn details in the form of 2D CAD drawing
- developing a 3D and a BIM models
- 3D mesh model adapted for 3D printing
- virtual tours
- high resolution orthoimages
- high resolution animations and visualizations
The measurement of trees included in urban greenery causes many difficulties, mainly due to their irregular shape. The methods of their inventory in cities consist in determining the species, measuring the thickness of the trunk, height and location in the adopted geodetic system. Due to the time consuming nature and the huge impact of the person performing such measurements on their accuracy, laser scanning is increasingly used here.
The possibilities offered by the use of laser scanning:
- Determining the number of trees in the scanner’s work area
- Very accurate measurement of the thickness of the tree trunk at any height
- Measurement of the total actual height of the tree – using traditional methods, this measurement is difficult to perform and burdened with errors of the instrument and the observer
- Determining the height of the base of the tree crown, shape of the crown and its range at any height
- Determining the inclination of the tree trunk, its convergence and deformation
- Measurement of the thickness of individual branches and the angle of their embedding
- Visualization and modeling of trees, shrubs and other objects within the scanner’s range for planning purposes.
ARCHITECTURE AND SPATIAL PLANNING
3D models of urban buildings are a perfect complement to traditional maps in spatial planning. In addition to the airborne laser scanning used so far, terrestrial laser scanning is increasingly used to register urban areas with a smaller area or individual objects.
Advantages of terrestrial laser scanning compared to airborne laser scanning:
- lower cost of data acquisition
- provides accurate data on buildings, while data from airborne scanning only gives information about the roofs of buildings, and models built on their basis have an approximate shape
- terrestrial laser scanning can be performed anywhere, while aerial data is not available for the whole country
Data from terrestrial scanning is an excellent base for further analysis in the GIS environment:
- designing new buildings
- visualization and verification of planning plans
- determining how the planned buildings limits visibility from existing buildings
- determining the shadow created by the designed building in relation to the existing building
- determining the so-called building silhouettes against the sky
