Trimble Inpho Software Suite Extends Photogrammetric Deliverables for Broad Range of Geospatial Applications

Two New Capabilities Increase Flexibility for Photogrammetrists Generating Highly Accurate Deliverables

Inpho v9 DensePointCloud

Trimble has announced a new version of its Inpho office software suite for photogrammetry. The suite includes two new capabilities:

  • MATCH-3DX software for the creation of rich 3D point clouds and true orthomosaics
  • MATCH-3DX Meshing add-on for the generation of photorealistic textured meshes

The announcement was made at INTERGEO 2018, the world’s largest conference on geodesy, geoinformatics and land management.

Inpho version 9 combines the classical photogrammetric capabilities of the existing MATCH-T DSM product with modern 3D workflows. The addition of the new products, plus continued enhancements, further establishes Inpho as a comprehensive software suite available for the production of photogrammetric-based deliverables.

Inpho v9 MESH

The new MATCH-3DX software incorporates state-of-the-art Semi Global Matching (SGM) techniques that enable photogrammetrists to reach a new level of quality and precision when generating large scale point clouds and true orthophotos from aerial (frame) images. Through the high resolution data sets, photogrammetrists can more clearly identify edges of surfaces, such as building corners and roof lines, enabling the extraction of highly precise measurements, CAD objects or Digital Surface Models (DSM). The new True Orthophoto capability ensures that each image pixel is directly related to the terrain height, simplifying mapping and the overlay of GIS data, especially for urban mapping applications.

Inpho v9 TexturedMESH

With the new MATCH-3DX Meshing add-on, photogrammetrists can generate highly accurate, photorealistic textured meshes that enable non-professionals to easily navigate and understand the real world environment. The 3D textured meshes provide an efficient data type for use within industry leading GIS systems and web-based 3D visualization services—often used for 3D city modeling, construction simulation and gaming applications.

“Inpho version 9 combines both classical photogrammetric processing with new true orthos and photorealistic textured mesh deliverables, all in a single software environment,” said Tim Lemmon, marketing director of Trimble Geospatial. “Photogrammetrists can take advantage of the streamlined workflows and reduced training costs while having the ultimate flexibility to choose the workflow and deliverables best suited to their client’s needs.”

Trimble Inpho version 9 is expected to be available in fourth quarter of 2018 through Trimble’s Geospatial Distribution Partners. For more information, visit: trimble.com/Inpho.

Leica Geosystems Increases Efficiency with Hydrographic Survey Systems Upgrade

New Leica Chiroptera 4X, Leica HawkEye 4X save more than 50 per cent in flight costs

Leica Geosystems, part of Hexagon, announced today the availability of Leica Chiroptera 4X and Leica HawkEye 4X. The latest upgrades introduce a new bathymetric LiDAR high resolution technology that increase the bathymetric point density by a factor four.

The higher point density allows customers to deliver high resolution products at reduced operational costs. Flight cost savings of 50 per cent can be achieved for typical bathymetric LiDAR end user specifications. The depth penetration increases up to 10 per cent with the new technology while not affecting the turbid water performance or accuracy.

Nova Scotia Community College is validating the new Chiroptera 4X bathymetric high-resolution technology in test projects on Canada’s east coast in turbid water conditions. “The four times increased resolution dramatically improves our ability to detect objects, even on the scale of features 1 metre by 1 metre where the increased number of points can be used to further clarify the objects location and details. For vegetation mapping, the increased resolution of the sensor provides us an unprecedented level of detail related to vegetation and other materials on the seafloor. We have also detected new seabed features not discovered from previous bathy LiDAR surveys in the same area, which indicates an increased sensitivity of the solution,” said Tim Webster, research scientist, Applied Geomatics Research Group (AGRG) Centre of Geographic Sciences (COGS), Nova Scotia Community College.

The 4X technology is available as an upgrade package to all current Chiroptera II and HawkEye III customers and will be integrated in all new bathymetric LiDAR systems. The improved resolution, depth penetration and accuracy provide substantial benefit for environmental and coastal monitoring, inland waters mapping, infrastructure planning, and near-shore applications.

Maximising efficiency
Typical end user specifications require two to four points per square metre for the highest quality level shallow bathymetric LiDAR data. This is easily achieved with a single flight line with the new Chiroptera 4X or HawkEye 4X shallow channel, while in previous generation double coverage was needed. This improvement saves half of the flight costs alone.

With the depth penetration of 2.7/k and collection of 140,000 points per second of the Chiroptera or HawkEye shallow channel, the new 4X technology offers an unmatched shallow water performance in respect to point density, turbid water performance and depth penetration. For the HawkEye deep channel, the 40,000 points per second collection is market leading in the industry and can easily deliver IHO order 1B data from single flight line.

“Optimising a bathymetric LiDAR system has always been a trade-off between sensitivity (depth penetration) and resolution. Our new 4X high-resolution technology allows us to improve both those parameters without any tradeoffs,” said Anders Ekelund, Hexagon’s Geospatial Content Solutions vice-president of Airborne Bathymetric LiDAR. “Performing advanced high-density site surveying allows users to extract better details for both above-water and underwater features, increasing our knowledge of coastal and inland waterways and habitats.”

Stencil 2 incorporates Kaarta’s latest intelligent mobile mapping advances. Automated Floor Leveling/Sectioning algorithms identify floor structures and smart-scan leveling for better scans and reduced post-processing time. Floor Planner automatically levels, rotates, and generates 2D images of a “slice” from a point cloud, generating 2D floor plans for large interior spaces such as warehouses or stores on the spot and eliminating many steps in the workflow.

Stencil 2 accurately maps exterior and large interior environments quickly and easily with a range of up to 100 meters and a data rate of 300,000 points per second up to 10Hz. Kaarta’s integrated 3D mapping and real-time position estimation allow capabilities not possible with fixed-base scanning systems. Stencil 2 further solidifies the feasibility of mobile mapping as a stand-alone solution while also widening the possibilities of using mobile mapping to complement or augment other scanning methods.

Stencil 2’s ease of use, breadth of applications, and streamlined workflow make it the perfect choice for infrastructure inspectors, surveyors, engineers, architects, facilities planners, security personnel, or anyone who needs an easy way to document the 3D world quickly and dependably.

Stencil 2 is now shipping worldwide. Upgrade packages are available to current Stencil owners.

Project Update: World’s First 3D Printed Steel Bridge

MX3D Printed Bridge at DDW by Adriaan de Groot

Amsterdam based startup MX3D has finalized its 3D printed steel bridge. The project is still ongoing, the smart bridge project (with stability tests) will last over the next 2 years. For this they will regularly use the FARO Laser Scanner and BuildIT Construction software.

The Bridge, designed by Joris Laarman Lab, with Arup as lead engineering partner is now ready to be installed at its final location, but will first be on display at the Dutch Design Week (DDW) in Eindhoven, from October 20th till 28th 2018.

In addition to its unique construction, the bridge is also a living laboratory for data scientists. It is instrumented by Autodesk, Force Technology, Imperial College London, Lenovo & HBM with an innovative sensor network. Data obtained from the sensors visualize intelligence about bridge traffic, structural integrity, and the surrounding neighborhood and environment. During the DDW visitors are invited to walk over the bridge to generate the first data set. Data from the bridge will be used by partners like The Alan Turing Institute, the UK’s national institute for data science and artificial intelligence, along with Autodesk to build a digital twin model and sensor network which use advanced data analysis to monitor the bridge’s performance in real-time. The work on this 3D printed bridge will contribute to the future of safe, efficient and data-driven engineering by monitoring the structure as thousands of people and bicycles traverse the bridge hourly once in place.

Arup, the project’s Lead Engineer, and researchers from The Alan Turing’s Data Centric Engineering Programme (a consortium of researchers from Imperial College London and the University of Cambridge) have performed a successful load test of 10+ ton this September. Comparisons between predictions from computer models that the team have developed with the results from this test will be made to demonstrate the load carrying capacity of the bridge and provide invaluable structural performance data.

SMART BRIDGE
The consortium of mathematicians from The Alan Turing Institute have teamed up with MX3D to deploy a smart sensor network to develop a new data centric engineering approach for 3D printed structures. Arup, Imperial College, Autodesk and Force Technologies are actively involved in the design, install and use of the sensors network.

These sensors will collect structural measurements such as strain, rotation, load, displacement and vibration, and will measure environmental factors such as air quality and temperature, enabling engineers to measure the bridge’s health in real time and monitor how it changes over its lifespan. This data will also allow us to “teach” the bridge to understand what is happening on it, how many people are crossing it and how quickly.

The data from the sensors will be used as input for a ‘digital twin’ of the bridge, a living computer model that will reflect the physical bridge with growing accuracy in real time as the data comes in. The performance and behaviour of the physical bridge can be tested against its digital twin, which will provide valuable insights to inform designs for future 3D printed metallic structures and ensures it is safe for pedestrians under all conditions.

Pivots
Like all innovative projects the MX3D bridge project required several pivots. The initial design for the 12 meter metre bridge has changed significantly. Based on material research and structural testing Arup and Joris Laarman Lab created a structural design strategy. This led to the final bridge design by Joris Laarman Lab in early 2017.

In March 2017, the printing and assembly of large segments of the bridge began. In parallel MX3D engineers have continued working on realizing their vision of robots autonomously 3D-printing infrastructure. Last summer, a robot was placed on the bridge. It validated the company’s vision and confirmed that robots will be able to print bridges without human intervention.
