Aerial photogrammetry and 3D scanning
Aerial photogrammetry and 3D scanning
Using photogrammetry we collect and process data.
We scan large landscapes and also focus on small areas and objects from which we create accurate 3D digital models.
Definition photogrammetry
Drone photogrammetry is a method of collecting and analysing data using drones that take pictures of the Earth's surface. The acquired images are processed into detailed 3D models, orthophotos and elevation models. This technology is designed for professionals in construction, surveying, agriculture and environmental planning, where accuracy and speed of data collection is key.
Photogrammetry from a drone
We are not surveyors, but we help surveyors, designers and builders collect data using photogrammetry and 3D scanning in difficult to access terrain with industrial RTK drones with high accuracy.
Buildings
Modern photogrammetry method with a drone calculates the extracted cubic volumes of rocks and areas, which allows to inventory the external mass and volume stores
Digitization
We preserve aged objects using detailed 3D laser scanning. In this way we can create a 3D model of buildings, statues, castles or other cultural monuments.
CGI & VR
Using aerial photogrammetry and 3D scanning followed by digital reconstruction, we deliver 3D models to CGI studios that use them in video games or construction
Movies
We also have experience with the use of photogrammetry and 3D laser scanning in films and documentaries
After flying we form
- 3D models
- Pointcloud / Pointcloud / Mesh Model
- 2D maps with terrain profile - DSM / Heatmaps
- Orthophotomaps
- Cubature
Benefits drone photogrammetry
Ability to track changes over time
Drone photogrammetry facilitates regular monitoring of changes on construction sites, in nature or on agricultural areas. This makes it possible to efficiently monitor the progress of work or environmental changes in real time.
Speed of data collection
Drone photogrammetry allows for faster acquisition of large amounts of data over large areas or complex sites, speeding up the entire mapping and analysis process compared to traditional methods that are more time consuming.
Accessibility and security
Drones can safely reach hard-to-reach or dangerous locations such as steep slopes, rocky terrain or buildings under construction where traditional surveying could be risky.
Accurate and efficient drone mapping
Our unmanned aerial systems (UAS) for photogrammetry are effectively used to map large areas and urban areas, achieving perfect 3D models for construction projects. We can take tens of thousands of photographs in a few hours, which we then process in proven professional software.
Drone photogrammetry is highly versatile and can be used in a variety of industries - from urban planning and terrain analysis after natural disasters, to surveying mining areas and monitoring vegetation. Rapid data collection reduces costs, minimizes manpower requirements and ensures safety. Our realistic 3D models and orthophotos created from drone imagery can be easily integrated into GIS, BIM and other digital platforms, leading to better decision-making and more efficient planning.
Frequently Asked Questions
What is drone photogrammetry?
Drone photogrammetry is a modern technology that uses drones to create accurate maps and 3D models of landscapes, buildings or other objects. During flight, the drone automatically takes a series of photos from different angles and heights, making sure that the individual shots overlap, which is essential for high-quality data processing. These photos are then uploaded to special photogrammetry software that can piece the photos together into a coherent model based on common points in the images. The model thus created can take the form of an accurate orthomosaic (a 2D map without distortion) or a detailed 3D model that realistically captures the shapes and elevation of the terrain, buildings or other objects in the area.
What formats can I export 3D drone photogrammetry models, 2D orthophotos and elevation models to?
The most commonly used formats for exporting 3D models are .obj, .ply and .laz. Orthophotomaps (2D) are available in .tiff, .jpg and .kmz formats, and for digital elevation models (DEM) we use .tif or .asc. These formats are optimized for different types of processing and visualization, allowing their wide use in CGI, GIS, architecture, surveying and construction. We can also export to other formats according to the client's needs.
What is 3D building scanning?
3D building scanning is the process of creating an accurate three-dimensional digital model of a building or part of a building. This method uses special technologies such as Photogrammetry and Lidar to capture the shape, structure and details of a building. The result is a detailed and faithful digital representation that captures the dimensions, surfaces and often the texture of the building.
What is 3D terrain scanning?
3D terrain scanning is a method of creating accurate three-dimensional models of a surface, often using technologies such as Lidar and photogrammetry. Lidar uses lasers to measure distances and create a dense "point cloud" from which a detailed 3D model is created. Photogrammetry, on the other hand, combines photographs from different angles and heights to create a model. These methods make it possible to capture the relief, height and texture of landscapes and objects. 3D scanning is used in surveying, construction, archaeology and environmental monitoring.
How much accuracy and detail can you achieve when flying an RTK drone and using professional software?
With advanced GPS systems and high quality flying photogrammetry equipment, we can capture extremely high resolution image data, allowing us to create maps and models with centimeter accuracy. This accuracy is crucial for construction projects, agriculture and infrastructure monitoring.
How long does it take to process drone photogrammetry data?
The processing time depends on the amount of data acquired, the type of project and the performance of the processing technology. Processing can take from a few hours to several weeks.
What are the advantages of drone photogrammetry over traditional methods?
Drone photogrammetry is fast, efficient and affordable compared to traditional methods such as aerial photography or ground surveying. It also allows you to capture details from hard-to-reach locations.
