Unmanned aerial vehicles aid in architectural design

There are several possibilities for using aerial photographs from unmanned aerial vehicles in architecture:

Presentation of Completed Buildings
A view of the building from above is not only extraordinary and captivating in itself, but it also provides interesting information. Thanks to the overview, the displayed building can be well understood as a whole, highlighting its volumetric relationships and overall shape best. At the same time, the context and connections to the surrounding environment are clearly visible. For larger buildings, aerial photography is the only meaningful form of presentation. Unmanned aerial vehicles allow for depiction from relatively low heights, making it possible to present the object in such a way that the overall concept of the building is clearly readable while preserving the details.

Site Analysis
Aerial photographs from low altitudes are an excellent source of data for preparatory work before starting the design phase. They quickly and clearly inform about the situation in the area and serve as an ideal basis for initial discussions and considerations among the investor, architect, and authorities regarding the planned intention, and they are also useful in subsequent conceptual work.

Photos for Inserting 3D Visualizations
In the presentation of building designs, 3D visualizations are almost exclusively used today, which are usually inserted into a real photograph from a chosen viewpoint. In the case of visualizations displayed from a bird's-eye perspective, it was until recently necessary to painstakingly model the surrounding environment because obtaining corresponding photographs was impossible. Hivision.cz produces photographs from precisely defined coordinates in space, so inserting a rendered overhead visualization into a photograph is very easy. Inserting the model into an aerial photograph is a quick and economical way to realistically present the proposed solution. Another specialty is capturing panoramic photographs from specific floors of the future building, which will serve to showcase the actual views from the interior.

Documentation of the Construction Process
The unmanned aerial vehicles of the Hivision.cz project can be programmed to take photographs from precisely defined positions. In the case of time-lapse documentation of the construction process, photographs can be taken from the same locations each time, which can then be processed into a slideshow animation presenting the growth of the building.

Technical Parameters
Hivision.cz has equipment with the following parameters:

• max. height: 120 m (can be higher by agreement)
• max. distance from the take-off site: approximately 200 m
• Flight weight: approximately 4.5 kg
• Stabilization in space: GPS navigation, digital altimeter with an accuracy of 0.5 m
• Stabilization of the photographic equipment carrier using gyroscopes and accelerometers for sharp images
• Real-time image transmission from the camera equipment to the ground
• Resolution of photographs up to 50 Mpix
