VIAMETRIS Chooses Ellipse-D Inertial Navigation System for its bMS3D-360 Backpack-Based Scanning Solution Print E-mail
Written by SBG Systems   
Wednesday, 28 March 2018

March 28th2018, Carrières-sur-Seine, France - 2018 VIAMETRIS , specialist of SLAM-based mobile scanning systems, completes its product range with a backpack-based scanning system called the “bMS3D-360”. The company continues to rely on SBG Systems’ expertise in inertial navigation by integrating the Ellipse2-D, an inertial navigation system with embedded RTK GNSS receiver.

VIAMETRIS has been developing SLAM-based scanning systems for more than 10 years, including the iMS3D, a full indoor mapping system, and the VMS3D, a car-based mapping system. Capitalizing on this expertise, the company adds the bMS3D-360 to their exceptional offer.

bMS3D-360, The Backpack-based Mobile Scanning System
The bMS3D-360 has been designed for the most challenging environments where GNSS is not accessible (indoor) or highly perturbed (urban canyons, forest, etc.).
The workflow is simple. The surveyor starts the system, checks on a tablet that the GNSS and inertial information are computed, and starts the survey. Back at the office, the user launches the INS/GNSS post-processing software to increase orientation and position accuracy, and then uses the VIAMETRIS software to georeference and colorize the point cloud. Collected data are ready to be imported into the most common design software. This workflow (from collection to plan drawing) is quickened by 7 times in comparison with a traditional method.
Additionally, the bMS3D-360 is the only backpack to offer a 360° camera which greatly simplifies the treatment work. When navigating in the point cloud, the user opens a unique picture of the 360° scanned environment instead of looking at 4 different camera points of view.

Ellipse2-D, The RTK Inertial Navigation System to aid the SLAM computation
The Ellipse2-D from SBG Systems is a very compact inertial navigation system integrating an L1/L2 GNSS receiver. This industrial-grade INS computes roll, pitch, heading as well as position thanks to the embedded Extended Kalman Filtering.

In real-time, Ellipse2-D orientation data are used to correct the equipment attitude and help the SLAM computed heading. The embedded GNSS receiver provides absolute positioning to the point cloud as well as altitude constraint. When the GNSS faces sources of disturbance, the INS maintains the trajectory were the SLAM technology is limited. Jérôme Ninot, Founder of VIAMETRIS explains this choice: “It has been years now that we work with SBG Systems and the Ellipse Series in particular. We have always relied on these robust inertial sensors, so when it came to choose an INS/GNSS system for our backpack, we were glad that the Ellipse2-D was already integrating a GNSS receiver.”
