Autonomous Inspection of Roads

In the near future drone-based automated inspections of roads will replace old and costly inspection methods.

In order to maintain safe roads and prolong their service life, frequent inspections are needed to identify damage in the road, assess vegetation encroachment etc. Previously, this task was very challenging and costly, due to the sheer length of roads, the complex diverse environments they reside in.

Drone-based automated inspections will soon replace old inspection methods. The key is automating the process to be able to reach the needed scale to make the process cost effective.

Drone Harmony’s road scanning solution

The new flight plan “Linear Scan” in Drone Harmony Cloud web solution is perfect for gathering data around roads, pipelines or railroads.

In the following months, our linear scan features will be enriched further and combined with the ability to follow complex terrain. The road scanning solution, featuring the combination of terrain aware flights with linear scan will enable full flexibility in performing road surveys in arbitrary terrain and at arbitrary altitude above ground.

Drone Harmony’s road scanning solution will import both terrain elevation models and models of the road to be scanned. The planned flights will be computed automatically and optimized for the imported data. This is exactly the kind of workflow that enabled the positive outcome in the following use case.

The result will be a simple repeatable workflow enabling to cover many miles of road per day.

A use case

As part of our work towards enhancing our enterprise solution, Drone Harmony has been working intensively on the challenges and solutions of road inspections. We recently collaborated with the Slovenian company IGEA to perform a precise reconstruction of a 11KM stretch of mountain road for an inspection and measurement job issued by the Slovenian government.

The full 11km stretch of mapped mountain road

Andraz Krivic from IGEA performed flights using Drone Harmony’s road inspection solution (beta). He collected about 3600 images in only 1.5 days of work with his Inspire 2 platform and generated an accurate 3D model of the road stretch that was used for analysis and measurements. Due to the difficulty of the terrain and complexity of the various obstructions in the scenery, such a task previously required much more time from skilled pilots and the results were of lower quality.

Business intelligence derived from drone data is only as good as the data that is used to generate it.

What our customers say

Drone harmony would have to be the best equipped flight planning app I've ever used. It works perfectly for vertical and complex structures, along with a large number of mission types to achieve the best results for your target asset.

Danny Elassad, Chief Remote Pilot, Hoverscape

Drone Harmony is the best Flight Planning Platform I've used to cover the dynamic terrain of our mining business with it's Terrain Following feature.

Muhammad Ilyas, Deputy Manager Mine Planning, Sindh Engro Coal Mining Company (SECMC)

Amazing app, easy to use and powerful. Offers all the things I need for scene inspection of many kinds (towers, antennas, construction sites, private residential zones, etc...). Also good mapping grids and parameters setting.

Jose Benitez, Co-Founder, TucanoRobotics

Excellent application, it is worth going for the paid version. It works perfectly, even with simple drones like DJI Spark.

Luis Eduardo Cuevas Correa, Founder, Lekazo

Obtaining a point cloud of the entire site in a few hours using a drone is a huge benefit to the schedule and the budget.

Jesse Creech, VDC Coordinator, Brasfield & Gorrie

Drone Harmony proved itself admirably, and we achieved in automated flight what would have taken enormous risk and complexity in manual flight.

Michael Appleyard, CEO, Drone Inspection WA

Setting up our missions in Drone Harmony has been easy thanks to great tutorials and excellent support from the Drone Harmony Team. Thank you!

Dwayne Marx, Founder

With the Drone Harmony application data acquisition was consistent, the flight patterns and automation provided us with consistent high-quality models for the purposes of tower inspections.
