How Do You Simplify the Detection of Material Damage?
You teach a computer to do it.
What Does T2D2 Detect?
T2D2 can identify most common building envelope materials . . .
Brick Masonry • Concrete • Glass Curtain Wall • Steel • Stone Masonry • Stucco
. . . and can detect a wide range of defects . . .
Corrosion • Cracked Mortar Joints • Cracks • Displaced Masonry • Efflorescence • Erosion • Miscellaneous Abandoned Items • Moisture • Open Mortar Joints • Peeling • Spalls • Spalls with Exposed Rebar • Stains
. . . And T2D2 Provides a Variety of Useful Modules
T2D2 lets you upload images for multistep inference through the platform’s computer vision models – first identifying materials and
then detecting damage. Engineers then review the detections, add annotations to those that are valid, mark false positives and geotag
them to specific locations on drawings of the structure.
Since most orthomosaics (stitched composite images) provide a complete representation of a façade or roof, they don’t include separate geotags. T2D2 applies orthomosaic models using a “sliding window” approach to mark damage and prevent double-counting of conditions on images with overlapping areas.
Condition Assessment Reports
T2D2’s secure online portal maintains a record of all detected damage and associated metadata, including engineer reviews, and
can generate reports that serve as a basis for repair efforts.
T2D2 evaluates the individual frames of videos, tracking detections across multiple frames to filter out false positives.
Drone surveys of buildings often produce 3D photogrammetric models. T2D2 performs damage detection on the original 2D images
and geotags the 3D model using the mapping from the photogrammetry process. The T2D2 portal lets you interact with the 3D model
containing the associated detections.
T2D2 processes thermographic images to detect anomalies such as leaks and moisture entrapment in façades and roofs.
T2D2 processes 360-degree panoramic tours (“panotours”), adding damage-condition annotations and providing a platform for visualizing the combined results.
