Having recently invested in a Leica Pegasus:Two Mobile Mapping System to extend our existing Street Level mobile mapping service, the Getmapping team were invited by Leica to try out their wearable mobile mapping solution - the Pegasus:Backpack.
Whilst the Pegasus:Two system enables the rapid and simultaneous collection of both high-resolution panoramic imagery and high-density point cloud data from a moving vehicle, the backpack offers a portable platform to collect data indoors, outdoors and underground. The system is typically suited to areas that are inaccessible to the Pegasus: Two system but reachable by foot – such as pedestrianised areas, transport concourses, shopping precincts, underground infrastructures and car parks.
Equipped with five cameras offering a fully calibrated 360 degrees view and two LiDAR profilers with an ultra-light carbon fibre chassis, the multi sensor platform is designed for rapid and regular reality capture.
On a crisp Monday morning, we headed to Pancras Square in London to meet the Leica team. After a quick demo of how the kit works, the backpack was put on and we were off surveying – it really was very fast to set up and very simple to operate. And as it weighs less than 15kg, the team felt that it was a ‘bearable wearable’, offering an efficient way to navigate areas by foot (or by bike) to capture survey data.
“Over the past few years we have seen more companies producing survey backpack solutions. The trend will be towards lighter weight and smaller components with higher specifications and longer battery life. This is an interesting proposition for Getmapping as the backpack would add to our capabilities for capturing data not just from aerial platforms and down to street level, but indoors and restricted spaces too.”Martin Tocher, Innovation Director, Getmapping
Overall we all found the Pegasus:Backpack to be a dynamic offering - a fast and flexible solution to fill the gap in surveying areas that the Pegasus:Two system physically can’t reach.
“The Leica Pegasus:Backpack is a light, portable and ergonomically designed kit, allowing users to perform surveys comfortably and safely in accordance with the EU legislations. Combining the Simultaneous Localization and Mapping – SLAM technology with the Inertial Measurement Unit – IMU precision, the Leica Pegasus: Backpack ensures the best positioning in places where the Global Navigation Satellite System – GNSS - may have interruptions or not accessible by our Leica Pegasus:Two system.”Alex Alves, Mobile Mapping Team Leader, Getmapping
With extensive uses also across asset management, BIM modelling and within GIS systems, the platform synchronises imagery and point cloud data, providing the complete documentation of the location surveyed for clients.
“Being able to collect this type of data will be invaluable for our clients. The Pegasus backpack allows you to capture data quickly and efficiently in area’s inaccessible by vehicle and therefore enables you to collect and deliver 100% coverage of a customer’s area of interest. The scope of use of the data is expanding all the time, from asset collection to addressing validation and building façade verification for Insurance purposes.”Neil Rennie, Business Development Manager, Getmapping
We are now processing the captured imagery and LiDAR data, keep an eye out for a follow-up blog.
