Drone videogrammetry company SkyeBrowse has released an inspection tool called Roof Damage Analysis to calculate roof dimensions and detect damage from aerial video, DroneDJ reported.
A pilot uploads drone footage of a building to generate a 3D model. The software detects the roof outline, calculates the total area in roofing squares, records pitch and facet measurements, and estimates the lengths of ridges, eaves and valleys. Users can manually alter outlines and facets if needed.
The tool also includes an automated screening feature that reviews up to 16 video frames and eight photos in about 20 seconds. It flags signs of wear or storm damage such as hail impacts, cracked tiles and missing shingles, pinning each finding to the 3D model for an inspector to accept or dismiss. SkyeBrowse said the system is designed for screening rather than replacing professional inspectors.
The update also connects with National Oceanic and Atmospheric Administration storm data within 40 kilometres of a property to suggest an estimated date of loss, and adds expanded mapping export formats for geographic information systems.
