Airbus ALTAIR – A First for Large Scale High Definition 3D Mapping
Airbus Defense and Space acquired Phase One Industrial iXM-100 inspection cameras with 35mm lenses to be integrated as a payload in the ALTAIR airship.
ALTAIR offers the first autonomous unmanned airship (Zeppelin), which is allowed to fly in cities and over crowds. Thus it enables the collection of high-resolution and ultra-precise optical data, which are processed into 3D city models of unmatched quality. The digital products of ALTAIR are the foundation to assist in smart decision-making and realistic simulations to pave the way for future cities.

Phase One 100MP cameras are an integral part of our IR 3D mapping solution as they provide us the baseline for a high definition 3D meshed model to be fused with IR data captured in one flight
Capture an Entire City in One Flight
Altair combines robust and proven airship platforms with latest technology to enable UAV remote sensing over cities, crowds, and beyond visual line of sight (BVLOS) missions for the first time.
The ALTAIR has a flight endurance of 3 to 8 hours, maximum payload of 10kg, flies at 60km/h, and reach a maximum height of 1800m. The airship is therefore ideal for aerial 3D Mapping on a city scale at low altitudes for data acquisition at a high GSD.
Airbus, vaireco (a 3D inspection technology startup) and MVV Energie AG (one of Germany’s leading energy companies) embarked on a project to acquire high-definition 3D IR data on a city scale using thermal sensors and Phase One Industrial 100MP RGB cameras.
- The benefits of the airship are:
- 10 times longer flight time compared to multicopters.
- Low noise and high public acceptance allow for special missions even at night
- Designed for safety, ALTAIR can fly where other aircraft and UAVs cannot
- Real-time and high-quality data service available remotely wherever you are

Energy Saving through Large Area Thermographic Data
Clemens Peters – consultant at MVV Energie AG – explains: “Large-area thermographic data acquisition of complete city infrastructures allows municipalities to support citizens to achieve energy saving targets, e.g. via our new platform CLIMAP. The data provides a decision baseline for renovation activities as well as support and allow prognoses on cost-saving effects.“

Creating a Future Industry with Thermal Sensors and High-resolution RGB cameras
“Currently aerial thermal imagery is used by ‘energy optimizers’ to detect sources of heat loss in buildings and homes. Our new high-definition imagery opens up new uses and opportunities for people to implement this technology in such as Firefighters; Police; Administrations for monitoring; Architects; Maintenance crews; Safety bodies; and Environmentalists. We are only in the middle of exploiting all the new use cases with domain partners,” – Robert Holder: Innovation Manager, Airbus Defence, and Space.

Redefining Thermal Imaging
The challenge was to develop a system for large-scale scanning, improving the infrared data quality, and process the data into 3D infrared (IR) models. The result has extraordinary analytical potential.
Wolfgang Herbst, business developer at vaireco and IR specialist says: “The combination of both Electro-Optical (EO) and IR 3D Models allow a completely new field of applications for infrared data. At the same time, accuracy and aerial performance are pushed into a new dimension. Thus, a number of new use cases have opened up. E.g. inspection flights of large-scale solar plants. (defect cells in solar arrays usually become hotter than normal).”
The fusion of high-resolution EO data with the low altitude IR data enables the detection of much smaller anomalies over a large scale while providing a direct cross-check with the optical data. This, in turn, leads to faster analysis. Since IR and EO data are captured simultaneously and the optical 3D mesh is used as a reference for IR, both models match naturally. Uses for IR data are increased as it is now represented at the correct geolocation.
