Matterport grabs $5M more to accelerate deep learning development for their 3D capture tech

3d capture tech

Matterport is picking up new funding as it looks to speed the development of deep learning tech in its capture technology which brings immersive views of spaces into 360-degree 3D

The company, which largely specializes in scanning spaces for commercial and real estate purposes, announced today that they’ve picked up $5 million in funding from Ericsson Ventures. This strategic raise brings the company’s total announced funding to $66 million according to Crunchbase.

As 3D rendering grows more important thanks to spatial computing platforms like VR and AR, Matterport has one of the biggest libraries of 3D environments thanks to its loyal and prolific users who have uploaded over a half million scans of public and private spaces which are already viewable in VR.

A big focus of this new investment is taking these 3D scans and striving to gather more and more insights from them through deep learning-based AI development which will not only help them understand what’s in a space but how to improve the quality of the 3D images themselves.

“Ericsson Ventures saw the tremendous opportunity Matterport has to extend our technology lead by using our massive library of 3D models as a deep learning training dataset to create AI that will be the basis for our next generation products,” Matterport CEO Bill Brown said.

In May the company launched its Pro2 camera, which addressed a big request from existing customers who were excited about the potential of 3D 360 room scans but still needed 2D images to put into print materials. The camera retails for $3,995 and is available now.

Huddesfield Designers Bring New Ginetta Racing Car to Life

The in-house design team at the 3M Buckley Innovation Centre (3M BIC) has used 3D technology and augmented reality to help Ginetta fine tune its latest prototype.

Having already provided a similar service for the launch of its first prototype in 2015, Ginetta approached the 3M BIC design team to animate its £1.3millon LMP1 machine.

This enabled the car manufacturer’s own in-house design team to visualise the cars development, as well as showcase it at a launch event at Silverstone Circuit to potential buyers.

Ewan Baldry, technical director at Ginetta, said: “3D technology is an important part of our design process and marketing. To see something on a flat CAD screen has a few limitations, so being able to see something you can move around is very helpful.

“The main thing with a project such as this, from a marketing point of view, is to show credibility in the early stages to demonstrate to people the direction you are heading in, therefore having 3D visuals was key.”

The animation for the LMP1 car was created using physical STL data (used for Computational Fluid Dynamics (CFD) testing or wind tunnel analysis) submitted to the 3M BIC design team by Ginetta.

Some adjustments had to be made to the original model in order for it to be re-textured with the corresponding racing livery, using Autodesk 3DS Max.

The team then rigged the car for animation and set the lighting for rendering purposes.

Paul Tallon, lead consultant designer at the 3M BIC, said: “3D rendering is a process in which an algorithm calculates the movements of a virtual photon on interaction with a surface of varying qualities.

“With the 3M BIC’s High Performance Computer and the latest Vray rendering software, we were able to get the detail to look as real life as possible in our render. This was particularly important for Ginetta who was looking for a realistic render to show their clients.”

As well as the on-screen render, the design team produced the car in augmented reality (AR) for use with the Microsoft Hololens, enabling people to walk around a scaled down holographic version of the car.

A 3D model was also printed in nylon by selective laser sintering (SLS) using the industrial additive manufacture printer on the 3M BIC’s Innovation Avenue, all of which were showcased at the launch event at Silverstone.

Ewan added: “Having worked with the 3M BIC team previously we knew they’d do the project justice. Again, we were really pleased with the service. We didn’t give them very much time, but they still produced something which was professional and to a high standard.”

Significant interest in the LMP1 has already been expressed following the launch event, from both new and existing customers.

The 3M BIC design team is currently working on the next stage of the process which involves creating a serious gaming experience that allows users, particularly racing drivers, to virtually test the LMP1 car on a track with varying different scenery and weather conditions to enhance the driver experience.

Leeds-based Ginetta, the leading British race car manufacturer, was founded in 1958 and acquired by racing driver and businessman Lawrence Tomlinson in 2005.

Since then it has taken the racing industry by storm, selling cars across the world and training some of the brightest stars in motorsport.

3D Simulations Show How Galactic Centers Cool Off

magnetic kink

The most extreme outbursts in the universe are the mysterious jets of energy and matter beaming from the center of galaxies at close to the speed of light. The narrow jets typically form in opposing pairs, and they are associated with supermassive black holes and other exotic objects. The mechanisms that drive and dissipate the jets are not understood.

A team of researchers has developed theories supported by 3D simulations to explain what’s at work.

“These jets are notoriously hard to explain,” said Alexander “Sasha” Tchekhovskoy, a former NASA Einstein fellow who co-led the new study as a member of the Nuclear Science Division at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), and the Astronomy and Physics departments and Theoretical Astrophysics Center at UC Berkeley. “Why are they so stable in some galaxies and in others they just fall apart?”

This rendering illustrates magnetic kink instability in simulated jets beaming from a galaxy’s center. The jets are believed to be associated with supermassive black holes. The magnetic field line (white) in each jet is twisted as the central object (black hole) rotates. As the jets contact higher-density matter the magnetic fields build up and become unstable. The irregular bends and asymmetries of the magnetic field lines are symptomatic of kink instability. The instability dissipates the magnetic fields into heat with the change in density, leading them to become less tightly wound. (Berkeley Lab, Purdue University, NASA)

Almost half the jets’ energy escapes in the form of X-rays and stronger forms of radiation. The researchers showed how two different mechanisms that are both related to the jets’ interaction with surrounding matter, also known as “ambient medium” and serve to reduce half of the energy of the powerful jets.

“The exciting part of this research is that we are now coming to understand the full range of dissipation mechanisms that are working in the jet no matter the size or type of jet,” he said.

Tchekhovskoy co-led the study with Purdue University scientists Rodolfo Barniol Duran and Dimitrios Giannios. They concluded that the ambient medium itself has a lot to do with how the jets release energy.

“We were finally able to simulate jets that start from the black hole and propagate to very large distances—where they bump into the ambient medium,” said Duran.

Tchekhovskoy has studied these jets for over a decade. He said that an effect known as magnetic kink instability causes a bend in the direction of some jets. This along with another effect that triggers a series of shocks within other jets appear to be the primary mechanisms for energy release. The density of ambient medium that the jets encounter serves as the key trigger for the types of the release mechanism.

“For a long time, we have speculated that shocks and instabilities trigger the spectacular light displays from jets. Now these ideas and models can be cast on a much firmer theoretical ground,” said Giannios, assistant professor of physics and astronomy at Purdue.

The length and intensity of the jets can illuminate the properties of their associated black holes like their age and size and if they are actively “feeding” on surrounding matter. The longest jets extend for millions of light years into space.

“When we look at black holes, the first things we notice are the central streaks of these jets. You can make images of these streaks and measure their lengths, widths and speeds to get information from the very center of the black hole,” Tchekhovskoy noted. “Black holes tend to eat in binges of tens and hundreds of millions of years. These jets are like the ‘burps’ of black holes—they are determined by the black holes’ diet and frequency of feeding.”

Nothing can escape a black hole’s interior, but jets manage to draw their energy from the black hole. In the black holes, the laws of physics allow them to spew energy and matter even when they suck in surrounding matter.

The friction and heating of gases spiraling in toward the black hole cause extreme temperatures and compression in magnetic fields. This results in energetic backlash and an outflow of radiation that escapes the black hole’s pull.

Earlier studies have shown how magnetic instabilities in the jets can occur when jets run into the ambient medium. A jet experiencing the instability can change direction when it rams into matter outside the black hole’s reach.

The same instability frustrated scientists working on early machines attempting to create and harness a superhot, charged state of matter known as plasma in efforts to develop fusion energy that powers the sun. The space jets, also known as active galactic nuclei (AGN) jets, are a form of plasma.

The latest study found that if an earlier jet had “pre-drilled” a hole in the ambient medium surrounding a black hole and the matter impacted by the newly formed jet was less dense, a different process is at work in the form of “recollimation” shocks.

These shocks, formed as matter and energy in the jet, bounce off the sides of the hole. The jet loses energy with every shock and immediately reforms a narrow column until its energy dissipates to the point that the beam loses its tight focus and spills out into a broad area.

“With these shocks, the jet is like a phoenix. It comes out of the shock every time,” though with gradually lessening energy, Tchekhovskoy said. “This train of shocks cumulatively can dissipate quite a substantial amount of the total energy.”

The researchers designed the models to smash against different densities of matter in the ambient medium to create instabilities in the jet that mimic astrophysical observations.

New, higher-resolution images of areas in space where supermassive black holes are thought to exist—from the Event Horizon Telescope (EHT), for example—should help inform and improve models and theories that explain jet behavior. Future studies could also include more complexity in the jet models, like a longer sequence of shocks.

“It would be really interesting to include gravity into these models, and to see the dynamics of buoyant cavities that the jet fills up with hot magnetized plasma as it drills a hole in the ambient medium,” Tchekhovskoy said. “Seeing deeper into where the jets come from—we think the jets start at the black hole’s event horizon (a point of no return for matter entering the black hole)—would be really helpful to see in nature these ‘bounces’ in repeating shocks, for example. The EHT could resolve this structure and provide a nice test of our work.”

A paper on this study was published in Monthly Notices of the Royal Astronomical Society.

Rendering Now Used by Law Enforcement to Solve Plane Crash Investigation

FARO Laser Scanner Render

Investigators will be able to view the entire scene of a recent fatal plane crash on Interstate 15 in extreme detail from any angle they want because of the high-tech equipment used to document the scene.

The FARO X330 uses lasers and a camera to construct any scene around it, resulting in a high-definition 3D map.

Sgt. Randall Akers, the accident investigation program manager for the Utah Highway Patrol, said the department bought seven of the scanners in 2014 and each cost about $40,000.

Akers said the machine takes multiple scans to document a typical crime scene and each scan takes between 4 and 12 minutes.

“Like any laser measurement device it shoots out a beam and gets a return to measure distance,” he said. “It does it in 360 degrees — in a circle.”

Akers said the scanner is particularly useful when it comes to plane crashes because law enforcement responding to the scene aren’t experts in that field. Using the FARO, they can get a true to life 3D rendering of everything — from cars on the side of the road to miniature pieces of debris — and send it off to qualified investigators.

The FARO is about the size of an XBox console and is weather resistant. The data it collects is analyzed with a program called SCENE.

Utah Highway Patrol Sgt. Todd Royce said the machines have been used at major crashes and some crime scenes, and Akers estimated they’re in use about once a week.

Akers said they use the FARO even at small crime scenes because, for instance, sometimes just using a single laser point to measure where a gun sits in a crime scene leaves crucial evidence behind.

“What if there happened to be some element to the handgun that didn’t get captured in a picture or something else?” he said. “Whatever that was, it’s gone.”

Akers said he was initially hoping the FARO would speed up crime scene analysis times to — in the case of the plane crash — speed up road opening times. He said that hasn’t turned out to be the case because of the multiple scans required and time it takes to set up scene markers for easier analysis, but they’re still incredibly useful.

The FARO scanner has other applications aside from accident reconstruction which includes industrial inspections, reverse engineering, and robot calibration, according to the FARO website.

Royce said the FARO renderings will be used by the highway patrol and the State Bureau of Investigation and handed off to the Federal Aviation Administration and National Transportation Safety Board if requested.
