Insitu, a wholly-owned subsidiary of The Boeing Company, has announced it is approaching the theoretical limits of accuracy for photogrammetry through advancements in its high accuracy photogrammetry (HAP) capability.
In June, Insitu’s latest accuracy improvement prototype validated that its HAP onboard payload now is accurate to within 5cm horizontally and 10cm vertically. This marked increase leads the industry in accuracies that can be obtained without ground control from a fixed-wing UAVs traveling more than 100km/ph from higher than 1,000 ft.
The HAP payload is a scalable payload as it does not rely on ground control. On a ScanEagle platform, more than approximately 60 square miles.
Insitu’s HAP capability provides persistent monitoring and cost-effective inspection of critical assets, capturing the data needed to analyse asset condition. Utilising HAP, customers optimize operations, and significantly reduce costs through eliminating the need for survey ground control points to achieve survey level accuracy.
In environments with bare earth and limited vegetation, such as open pit mining or rail and road infrastructure mapping and monitoring, the HAP payload now is an alternative to light detection and ranging (LiDAR), with the ability to produce imagery data as accurate as most LiDAR payloads, at a lower cost.
HAP also is available in a multi-spectral format which gives machine learning algorithms the information needed for automated asset inspection, including vegetation encroachment, standing water, infrastructure anomalies, and more.
“Insitu is geared to provide turnkey solutions in aerial data collection and remote sensing, and the increased HAP accuracy we have achieved is an exciting addition to our suite of solutions to drive efficiencies in our customers’ resource sector operations,” said Andrew Duggan, vice president of Insitu Commercial.
“We are excited by the possibilities these innovations in aerial imagery will bring to our customers.”
