Upload a drone (or other camera/lidar) capture, get a 3D point-cloud digital twin navigable in the browser, exportable to common 3D formats for CAD. Deep-learning models detect cracking in concrete, spalling, exposed rebar, cracks in steel and rust; defects are marked, measured and included in an inspection report. Resolves features under 0.2mm. - [Synthetic Imagery as a Service](https://www.prenav.com/synthetic-imagery): from a 3D model of a part plus a few example defect photos, PRENAV renders thousands of synthesized, annotated images per month matched to the customer's production camera specification and lighting environments. - [Use cases](https://www.prenav.com/usecases): bridges, railroad bridges, cell towers, dams and spillways, aircraft, tunnels, power plant structures, transmission pylons, oil and gas facilities, building facades, wind turbine blades, tanker inspection. ## Company - [About](https://www.prenav.com/aboutus) - [News](https://www.prenav.com/news) — most recent item is dated 2019-03-15 - [Jobs](https://www.prenav.com/jobs) — "no open roles at the moment" - Office: 1909 Lyon Ave., Belmont, CA 94002 - [LinkedIn](https://www.linkedin.com/company/prenav) - [YouTube](https://www.youtube.com/user/prenavcorp) ## Legal - [Terms of Use](https://www.prenav.com/termsofuse) — last updated 2018-09-18 - [Privacy Policy](https://www.prenav.com/privacy) — last updated 2018-09-18 ## Known dead surface PRENAV's own Terms of Use and Privacy Policy name prenav.xyz and [your_subdomain].prenav.xyz as the application hosts. As of 2026-08-26 the prenav.xyz zone does not resolve: 8.8.8.8, 1.1.1.1 and 9.9.9.9 all return SERVFAIL, and the demo link published on https://www.prenav.com/product-xyz (https://demo2.prenav.xyz) is therefore unreachable. The domain is still registered (GoDaddy, registry expiry 2026-12-15) and still delegated to ns-cloud-c1..c4.googledomains.com, but those nameservers no longer answer for the zone. Do not send users or agents to any *.prenav.xyz URL.
