Tailoring a drone for confined space

Protective cage

Allows contact with the walls without risk to the machine.

In a confined environment, trying to avoid any contact is unrealistic. It is therefore necessary to be able to bounce on the surfaces and continue the inspection.

Smaller size

A small diameter drone is more nimble to fly and fit in tight environments. Moreover, with a diameter of less than 40cm, the Stereo2 is able to cross most manholes.

Optical stabilization

Today, optical stabilization is the only way to overcome the lack of GPS signals in confined areas.

The Stereo2 is also able to record its movements in real-time for the pilot and to output them for 3D reconstruction.

Illumination

Lack of light is a recurring problem in confined environments. Yet, it is essential for the cameras to be able to record the area.

A Wide, uniform, and powerful lighting is mandatory to operate effectively.

Dust resistance

Present absolutely everywhere, it clogs up ventilation and causes the equipment to heat up.

The Stereo2 has a passive ventilation system with wide openings that allows quick cleaning only with dry air.

Once airborne, indirect lighting methods such as the Stereo2’s dust mode are essential to ensure good visibility.

HD video feedback

The better the definition of the drone’s video feedback, the better the pilot’s ability to understand the hostile environments he is flying in.

Assistance modes

Distance

Activates a protective bubble on the front of the machine. Protects the sensors by keeping a distance set by the operator.

Useful to keep the drone at a fixed distance from a wall to inspect it

Eliminates the risk of touching the edges of a pipe

Yaw-lock

Aligns the drone at a 90° angle from the surface to inspect. Works also on curved walls and therefore allows to inspect tanks without having to touch the yaw axis. The pilot remains in control of the yaw at all times, the drone will take over as soon as the joystick returns to the middle.

Roof

Keeps the drone at a set distance from any ceiling. Especially useful in pipes to let the drone manage the tracking of the slope

Using a drone in a confined environment is a tough job.
Better use a machine you can put your trust in.

Recording in 4K

The goal of any inspection is to get the best possible data set. For this, the Stereo2 carries a 4K camera.

Its fixed focus is factory set to provide a sharp image that will not be disturbed by any deposits on the lens.

The iso setting is automatic in order to simplify the pilot's work. To adjust the exposure at close range, simply adjust the power of the on-board lighting system.

12 000 lumens

The Stereo2 is equipped with a lighting system tailored for inspections in confined areas.

The 6 LED panels are adjustable from the remote control.

4 of them provide a uniform illumination in the front half of the drone, and 2 follow the camera movements to provide the best lighting possible for close-up inspections.

It is also possible to only use the pannels from one side of the machine to highlight the surface imperfections by lighting effect.

Facing dust

Industrial environments often come with a lot of dust. Once airborne, lifted from surfaces by the movement of the propellers, an opaque cloud can quickly take shape.

The indirect lighting system of the Stereo2 allows it to keep a perfect view of the environment in these conditions and allows the pilot to easily complete his inspection.

Photogrammetry

A 3D model gives you a new perspective on your inspection. Locating defects is easier than sorting through hundreds of pictures or watching a flight video.

Software such as Agisoft Metashape or Pix4D allow to create digital replicas from the videos taken by Stereo2.

The use of flight logs can also facilitate the work of reconstruction software by associating the samples to a precise place in space.
