In 2006 a group prepared NCHRP report 20 – 64 entitled, “XML Schemas for Exchange of Transportation Data.” Since then not much has happened. The concept was similar to the highly successful LandXML data exchange standard that over the past couple of years has also fallen on hard times with the loss of the landxml.org website, but I see it is back up. That is very good news.
I will be attending a meeting this week hosted by the Transportation Research Board to discuss whether there is interest in moving forward with an update of the TransXML schema. This could have implications for the use of mobile LiDAR data as well as 3D modeling in general.
Let me know if you have any thoughts and I will provide a summary of the meeting.
As yet another example of the convergence of the 3D professional and consumer worlds Hammacher Schlemmer is offering a “No Glasses 3D Tablet” for $350. They claim, “This is the only mobile tablet that displays 3D movies and images without cumbersome glasses. Using a parallax barrier laid atop its 8″ LCD screen, this tablet delivers a slightly different set of pixels to each eye, creating depth of field without uncomfortable, color-distorting lenses.”
I think the professional AEC world could find a use for this.
My friend Mike Olsen at Oregon State University is not going to be happy with me, but it seems that a group of geologist at the University of Oregon are doing some innovative work with LiDAR to better understand lava flows. Sorry Mike.
They recently used this technology to create high-resolution 3D models of the remains of Hawaii’s 1974 Kilauea and 1984 Mauna Loa eruptions. “When you go down to the meter-scale resolution, all of a sudden, it is possible to start analyzing flows in a way that we have never been able to do before,” said Kathy Cashman, a geologist at the University of Oregon who is involved in this research. “So it is opening up new ways of studying old flows and new opportunities for monitoring active flows.”
DJS Associates is donating its services in collaboration with an Oakland, Calif., nonprofit CyArk to scan the Lincoln Memorial in Washington, D.C. It will share that information with the National Park Service, which can use the model for reference and make it available to the public. CyArk has committed to digitally preserving 500 cultural heritage sites over the next five years, including a scan of Mount Rushmore, which it has already completed.
Okay, I am going to make a bold prediction for 2014. There is going to be an explosion of tablet-based, 3D data capture devices coming on the market Here’s another new one from Occipital called the Structure Sensor.
Looks like these guys have a computer vision background and have raised over a million dollars on Kickstarter. Their goal was $100k – unreal. Plus they want you to hack it.
Thanks to Arik Degani for the head up.
The Transportation Research Board is hosting the second webinar a three part series to inform the public about the recently published “Guidelines for the Use of Mobile LIDAR in Transportation Applications. This webinar will focus on the management issues. It is scheduled for Thursday, December 12 from 2:00 to 3:30 PM EST.
There may be a fee to attend depending on your affiliation. Please pass the word.
We are completing our third year of publishing LiDAR News magazine. I think you will agree that we have been raising the bar with each issue. Our plans for 2014 include publishing 8 issues with a couple of new format ideas. If you have an idea for an article please contact me. We can’t do it without you.
In this new issue we once again cover a wide breadth of topics from using laser scanning in a complex hospital construction project, to the use of augmented reality for plant BIM and the use of laser scanning to develop robotic aids for stroke victims, plus much more.
Thanks to all of you for your ongoing support and please tell a friend about LiDAR News.
In a recent industry market report they note that “the surveying technologies used for GIS are being shifted from photogrammetry technology toward LIDAR technology” as it is more accurate and less expensive than traditional photogrammetry. They predict the Global GIS market in the Transportation industry will grow at a CAGR of 12.64 percent over the period 2012-2016. Question – is the hundredth decimal place really appropriate?
Here’s an interesting finding. The report states that one of the major challenges in the market is the threat of the invasion of privacy. For instance, many governments have passed stringent regulations regarding the data provided in the GIS so that it cannot be used for any illegal activities.
I imagine the use of UAVs will come into play here as well.
Well this would be interesting. During the 60 Minutes interview with Amazon founder Jeff Bezos last night he revealed that they are working on the use of UAVs to deliver orders. In fact he had a video of a quad-copter taking off and delivering a package to a happy customer.
He did acknowledge that this idea was still in the development stage, but can you imagine what other data could be collected during the delivery mission? I am an early adopter, but this is a bit of a stretch for me to buy into. Perhaps in rural areas, but in a city or even suburbia it just seems to be the FAA’s worst nightmare.
As previously discussed and reinforced last night by Jeff they do intend to be the most customer-centric company in the world. Profit is not their prime motivation.
The brilliant people at MIT (Massachusetts Institute of Technology) are pushing the envelope again. This time it involves needing only one photon for each pixel in a depth map image – incredible. As reported in MIT News this technology could have a dramatic impact on the design of lidar sensors.
A conventional lidar system requires about 100 times as many photons to make depth estimates of similar accuracy under comparable conditions. The new system could yield substantial savings in energy and time — which are at a premium in autonomous vehicles trying to avoid collisions.
