Pix4D launches survey-grade 3D modelling on mobile devices

April 2021: CRJ Key Network Partner Pix4D, expert in photogrammetry, has announced the commercialisation and worldwide distribution of the viDoc RTK (real-time kinematic) rover, enabling ground based RTK-grade 3D scanning with iOS mobile phones and tablets through the Pix4Dcatch app.

The hand-held RTK rover is a replacement for more expensive ground surveying equipment that does not compromise on accuracy to achieve 3D, actionable results.

When the viDoc RTK rover is synchronised with Pix4Dcatch, it geotags the images of a 3D scan in real-time, while connected to any NTRIP service. Extensive research has revealed that it is possible to achieve 3D models with an absolute geolocation accuracy of less than 5cm.

Christoph Strecha, Founder and CEO of Pix4D, comments: “We are happy to see how Pix4D algorithms complement consumer tech to achieve professional-grade results. This was the case with drones a few years back. Now it’s the turn of mobile devices, allowing professionals to digitise the world and turn it into accurate 3D models at a fraction of the price. The new solution combines RTK accurate image tagging with photogrammetry and LiDAR (for LiDAR enabled mobile devices) processing.”

The viDoc RTK rover for Pix4Dcatch is now available for shipping to Europe. It is available for the rest of the world from May 20, directly through Pix4D or its resellers. The Pix4Dcatch app is free to download.
