Stereo2: The ultimate drone for stormwater inspection

One of the standout features of the Stereo2 drone is its compact design, with a diameter of just 39 centimeters (approximately 15.35 inches). This small size allows it to easily navigate through tight spaces, such as narrow culverts and stormwater channels, enabling comprehensive inspections without the need for extensive manual intervention. Additionally, the drone is equipped with a protective cage that prevents damage during contact with surfaces, ensuring operational safety in challenging environments where collisions are likely.

Unlike many drones that depend on GPS for stabilization, the Stereo2 utilizes stereoscopic camera stabilization and odometry for steady flight. This feature is especially beneficial in areas where GPS signals are weak or unavailable, such as deep culverts or dense vegetation. The optical stabilization compensates for the absence of GPS, allowing for smooth navigation and high‑quality data capture, even in complex environments.

Effective lighting is crucial for stormwater inspections, particularly in dimly lit areas. The Stereo2 excels with its advanced lighting system, which can project 10,000 lumens of illumination at adjustable angles. This powerful lighting ensures that even the most shadowed corners of drainage systems are well‑lit, allowing the drone's cameras to capture high‑resolution images and videos. Additionally, the drone’s dust resistance, facilitated by a passive ventilation system, maintains visibility in challenging conditions, ensuring uninterrupted inspections.

The Stereo2 is equipped with a 4K camera capable of capturing crisp photos and videos. The factory‑set hard focus ensures sharp imagery, while real‑time 1080p video feedback provides pilots with clear views of the inspected areas. The ability to adjust exposure settings improves data quality, and the photogrammetry capabilities allow for the creation of 3D models, aiding in the identification of defects and detailed analysis. Specialized software analyzes the inspection data to identify patterns, assess risks, and predict potential failures, supporting informed maintenance and management decisions.

The Stereo2's reliable radio and video link enable effective communication between the drone and the pilot, even in difficult conditions. Access to flight logs and inspection data is invaluable for post‑inspection assessments and creating digital records of the stormwater infrastructure using software like Agisoft Metashape or Pix4D.
