Three-dimensional surveying with the aid of a laser scans is the most modern, fastest, most precise and universally applicable method of obtaining building data today. The result of the scans taken from different points of view is a point cloud that can be converted quickly and in simple steps into a three-dimensional visualization of the measured object. This type of laser scanning is used in various areas, e.g. for surveying power lines, streets, industrial plants with integrated production facilities or architectural landmarks.
We use precision instruments from the renowned manufacturer Leica Geosystems. Our scanners capture up to one million points per second and deliver accurate measurement data even over long distances. Leica TruView enables us to view the point cloud directly on the Web, take measurements within it and embed comments. We also work together with the company Bestand 3D, as a result of which we are very familiar with the German standards.
The image of the scanned building requires careful editing before it is suitable for further use. The scan in the raw version shows a grainy black and white image, which provides an object visualization that is too detailed and therefore confusing and cannot be modified in CAD. Such visualizations are hardly suitable for use in project or modernization work.
For these purposes, it is essential to create 2D projections and 3D models in CAD formats. Often only a partial inventory is required for further processing, e.g. if only the inventory of a newly installed paint supply system to the paint cabins is to be carried out. In this case, laser scanning is an unsuitable method because it is overloaded with unnecessary information and is relatively expensive.
We know from experience when which method would be the best and take appropriate measures in advance so that the customer does not have to bear any avoidable costs.
There are many uses for 3D laser scanning. Architectural landmarks are inventoried in this way in order to create as-built documentation, visualization and presentation of the surveyed objects. 3D scanning technology also facilitates the planning of future construction projects wherever a three-dimensional map of the surroundings is required, e.g. when surveying railroad stations, highway junctions, dams and slag heaps. Another field of application is industrial and production facilities, where buildings, machines and installations are scanned in order to better assess upcoming modernization and optimization measures.
The company HOLDFORT deals with 3D inventory in all its facets, with a focus on buildings, industrial halls and production lines. Our many years of experience in the industrial sector, technical know-how and perfect mastery of CAD tools enable us to create high-quality, scan-based 3D models. We work in compliance with standards and in accordance with the customer's requirements so that subsequent modernization or reorganization of the plant can be easily organized.
