The subtle difference

Your business is our drive

Uwe Chalas, Co-Founder & CTIO

Twinsity’s beginnings are in drone engineering for building inspection, classical and 3D programming. In 2016, Uwe Chalas and Fabien Chalas started to bring these worlds together and developed a new software technology for real-time visualization of ultra-realistic 3D models.

In 2019, on this purpose, they founded the start-up Twinsity. With TwinSpect, Twinsity today offers an innovative software tool to efficiently inspect, evaluate and collaboratively edit projects by combining the high-resolution digital twin and the original drone images. This tool is opening up completely new, previously unimagined possibilities for virtual building and facility inspection.

Faster. Safer. More profitable.

Take your business to a new level.

With TwinSpect, inspections are realized faster because you save time and travel by streamlining workflow, speeding up your reporting, and reducing on-site appointments. Your inspection process is also significantly safer, as you completely avoid potential risks of a manned inspection, such as work accidents, scaffolding and climbing on the objects. As a result, you automatically operate far more profitable, especially since you have all the arguments on your side when it comes to new customer business as well. In short, TwinSpect will take your business to a new level.

How you bring true-to-life 3D models to life

You first export the inspection images of your drone inspection flight in the photogrammetry software of your choice. We recommend the RealityCapture software from Capturing Reality, which provides ultra-realistic and true-to-life 3D models with high-resolution textures revealing even smallest details. You can now import this project data into TwinSpect, and directly inspect, analyze and evaluate your object virtually and in high detail, as well as share and collaborate with project partners.

Drone Capturing

Drone Twinsity TwinSpect Survey

The drone flight generates the raw data of the object. It also captures areas that are difficult to access.

Photogrammetry Software

You export the 3D mesh model in OBJ format from your photogrammetry software.
