Photo sequences from UAVs (unmanned aerial vehicles) have become a feasible source for surveying, construction monitoring, and inspection workflows.

As such, Bentley Systems Inc.,, Exton, Pa., has acquired France-based Acute3D,, a provider of Smart3DCapture software for reality modeling.

Through reality modeling, observations of existing conditions are processed into representations for contextual alignment within design modeling and construction modeling environments. Rapid technology advancements in scanning and photography, especially the burgeoning application of UAVs for these purposes, are making the capture of such observations broadly and continuously affordable in sustaining infrastructure.

Acute3D software automates high-resolution, fully 3D representations from digital photographs taken with any camera, whether highly specialized or embedded in a smartphone. Scalable from site to city with precision limited only by the quantity and quality of photography, Acute3D technology can assure existing conditions are contemporaneously considered throughout the architecture, engineering, construction, and operations of any infrastructure asset.

“The world-class Acute3D developers have already achieved two breakthroughs, which remove the barriers to the adoption of reality modeling,” says Keith Bentley, CTO and founder, Bentley Systems. “First, Acute3D has made it possible for anyone to sufficiently capture existing conditions with just a camera. Of equal importance is the value of the Acute3D result. Rather than a voluminous cloud of discrete points, Acute3D produces a 3D ‘reality mesh’ intrinsically in the same geometric idiom as engineering models, readily aligning the real-world context.”

“With our team, we are very pleased to be joining Bentley to complete our reach. Together, we have already shared and embarked upon many new initiatives to incorporate reality modeling within design and construction modeling,” says Jean-Philippe Pons, cofounder, Acute3D.
