3D measuring of a building and BIM modelling

Single-family house documentation

With a laser scanner it is possible to completely measure the building in short time getting all the details and then to create the documentation of the construction. The processed point cloud can then be used for creating a BIM model. BIM is an effective tool for building management that is usually being developed during the whole period of building utilization and can contain a lot of useful information for many different groups of professionals.

Historical building

Complete documentation of a chapel before reconstruction

For many historical buildings it is often not possible to get any existing documentation in paper or digital form simply because the construction has never been documented. That's why in case of reconstruction it is necessary first to measure completely the building before the architects can start designing the new features. The time needed for the taking the measurements can differ depending on the size of the object and how accessible it is, but with laser scanners or drones capturing images it is possible to get quickly very detailed and accurate point cloud that contains all the necessary features. Depending on the requirement the data can be used for modelling the walls and roof construction, inventary documentation or any visualizing tools.

Quarries

Volume calculation of a material from aerial imaging data

Thanks to high accuracy of the data it is possible to use it for any deep analysis and calculations. One of the most used is volume calculation of material in mines and quarries. Flight over the place with a drone capturing images is one of the fastest methods of measurement and after a fast data processing it is possible to have the results in few hours. It is not necessary for anyone to enter the dangerous area and in most of the cases the works in the mine don't have to be interrupted. Also it is not a problem to repeat the measurement in regular intervals to get a complete record of the workflow.

Mapping

Mapping of an area before the beginning of earthwork

Mapping of an unpopulated area provides fast solution to get an accurate 3D model of the surface that can be later used for designing the new construction, volume calculation to determine the amount of earthwork and for other analysis needed. The output of this measurement can be not only the 3D point cloud, but also an orthomosaic, digital surface and terrain model and contours.

Height inspection

Detailed check of a height building

Height building, like bridges, towers and poles have to be checked regularly to determine the current condition of all construction features and eventually to prevent any technical problems. As these height buildings are usually not easily accessible the usage of a drone is an ideal solution. It is not necessary for the employees to take the risk when climbing the tower and also in most of the cases it is not required to turn off the inspected device.

Agriculture

Aerial imaging of agricultural fields and vegetation health detection

Drones are used also for vegetation mapping and crop health detection. After processing the captured data wide variety of outputs can be generated depending on the type of sensor used. Not only can it be an orthomosaic and 3D model, but when using a multispectral camera it is possible to create vegetation index maps (NDVI, NDRE, RVI indexes and others). Best known is the NDVI index - a useful tool to determine the vegetation health, time changes and phonophases analysis, yield estimate, water stress estimate and others.

The data capture can be repeated if required to record the complete process of crop growth.
