  • New Viametris backpack scanner integrates SBG Systems product

    Viametris, specialist of SLAM-based mobile scanning systems, has launched 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 real-time kinematic (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.

    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 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 common design software. This workflow (from collection to plan drawing) is seven times faster than a traditional method.

    The bMS3D-360 offers a 360-degree camera, which greatly simplifies the treatment work. When navigating in the point cloud, the user opens a unique picture of the 360-degree scanned environment instead of looking at four different camera points of view.

    The Ellipse2-D from SBG Systems is a compact inertial navigation system integrating an L1/L2 GNSS receiver. This industrial-grade INS computes roll, pitch and heading as well as position because of its 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.

  • Viametris mobile backpack scanner includes panoramic camera

    Mobile-scanning company Viametris has launched the bMS3D backpack mobile scanning system, which features an embedded 360° camera.

    Narrow streets and pedestrian zones are considered hurdles when it comes to mobile scanning. The new bMS3D-360 makes these tasks achievable. It is now available on the market and it comes with post-processing software. It will be presented at SPAR 3D 2018 in June.

    “Users of mobile scanning systems know how difficult it is to cover an entire city with this kind of system and how complex the completeness is,” said Jerome Ninot, founder of Viametris.

    Improved Data Exploitation with Panoramic Images. Viametris has found a solution to scanning challenges by developing the bMS3D-360: the mobile scanning backpack system includes a panoramic camera. This sensor allows the user to maintain continuity of results with mobile mapping systems on cars that already include this kind of camera. Operation and visualization with such 360° images are now easy to use.

    Since Google provided massive street views, people are used to navigating through panoramic images. Navigating through bMS3D-360 images becomes easy and intuitive compared to navigating with 3D point clouds, the company said.

    Ten years of experience have allowed Viametris to produce its GNSS mono-antenna system based on GNSS-free scanning (indoor or denied-GNSS area): the system trajectory is calculated by lidar-SLAM. It produces colorized point clouds with absolute accuracy of less than 5 centimeters under appropriate satellite reception conditions.

    Compared to many mobile scanners, this backpack does not rely on GNSS to work. If the GNSS reception is not good enough, control points can be added for absolute localization. The backpack can be used to scan all sorts of indoor areas such as airports, industrial buildings or shopping malls.

    The bMS3D-360 is lightweight. It protects the retractable camera an all other components since it is self-contained.

    Post process in VIAMETRIS PPiMMS Software. PPiMMS post-processing software manages the dataset coming from the system. Its mission is to calculate, control and improve the trajectories by calling lidar-SLAM functions, and reducing drifts, thanks to loop closure algorithms.

    The user can manually add GCPs to constrain the result when GNSS reception is poor. But, in most cases, the user will be able to include post-processed global positions (PPK) using GNSS post-processing software. Additionally, the panoramic camera can be used to colorize the point cloud using PPiMMS.
