Call for Partipants: Survey on using 3D Imaging systems for GD&T Assessment

The National Research Council of Canada (NRC) is conducting an online survey of companies who use, or could potentially use, short-range non-contact 3D imaging systems to assess part conformance to GD&T tolerance specifications. If you are interested in participating in this survey then please contact me at david.mackinnon@nrc.gc.ca so that we can send you and invitation and a link to the survey. This survey is being used to take a snapshot of the industry so that we can target our research programs in 3D imaging system standards development to better address the needs of industry. All responses will be kept strictly confidential. The survey runs until Friday, 23 January 2015.

An E57 Archiving group is being created. The focus of the e57 archiving group is on long-term retention of data for use in Historic Preservation and construction documentation. The goal is to take a collection of digital data gathered from a diverse set of sources and preserve it in a way that insures it will be usable in generations to come.

The data of interest is: 1) LiDAR scan data (point clouds) taken from a variety of manufacturer's equipment, 2) Photographs taken from a diverse set of sources for which the location of the camera can be known to a reasonable accuracy and 3) Meta data about the point clouds and pictures such as registration accuracy and field conditions.

We are currently nominating projects in a variety of fields where we have complete access to the Meta-Data required to complete the project. That data could take the form of bid specs for the job, field notes about existing conditions, or anything else that isn’t currently stored in the e57 file. From the types of meta-data identified in the representative samples we will create a list of recommended data types to add to the standard. We will then propose how the additional data can be included in the current e57 format through using an extension and which will require a turn of the standard to include it. Contact Ken VanBree - ken@ebuilts.com.

Here is a quote from a Spar Point Group article Safe doubles down on point clouds with FME 2013.

"As for that E57 standard, Safe is on board. While last year at this time Lutz told me not a single customer had even mentioned it, Lutz said that’s changed recently, and “some vendors started to pipe up about it.” That prompted an investigation, and now, “We look at it as a very rich specification that pushes us to have a very flexible internal model,” Lutz said. “It has the potential to make our product much better.” Previously, the guts of FME’s point cloud handling was based on LAS, but “with this implementation we created a user interface that’s good at mapping E57 components to LAS and vice versa,” and going forward E57 will serve that guts function."

"Lutz lauded the E57 library that helped with support and implementation, saying he gives it “high marks,” and that it makes working with E57 “not too bad,” despite it being fairly unwieldy. He predicted the market will begin to see subsets of E57 supported by groups of vendors who might start touting a “profile” of E57 that has some restrictions, but makes it easier to write software."

"He also said the fact that some have begun to choose E57 as their archive format – such as the University of Arkansas – indicates it’s here to stay." Sam Pfeifle

January 17, 2013
Here is a quote from a LiDAR news article FME 2013 Adds Support for ASTM E57.

"I just finished speaking with Dale Lutz one of the founders of Safe Software. They have just released FME 2013 which as you can see now has support for E57. To make a 30 min conversation short, Dale was so impressed with the performance of E57 that they are re-architecting their entire platform for 2014 in order to take full advantage of what the E57 libraries are capable of doing."

"He stated that because of the extremely large files sizes inherent with point clouds that the high performance of E57 will now be their model for all of FME’s data conversion engine. They have also created a number of utilities for manipulating point clouds that may be of interest. Similar to grid algebra for raster data, Dale calls this “point algebra”.

"There are few people more knowledgeable about geospatial data conversion than Dale. This is a remarkable tribute to all of the people involved in this effort. Thanks Dale for your vote of confidence." Gene Roe LiDAR news

Leica GeoSystems have announced support for a new series of code sprints with Open Perception. Code named PCL-LGSCS this open source project will run during the first quarter of 2013. Our expectation on the ASTM E57.04 subcommittee is that we will be able to make use of this effort to add compression to the E57 data interoperability standard.

November 19, 2012
Here is some more great news. Martin Isenburg has made available an e572las.exe converter tool that reads the LiDAR data from a *.e57 file and converts it to either standard LAS, compressed LAZ, or a simple ASCII TXT file. Here is the README.txt. See Martin's web site http://rapidlasso.com.

October 3, 2012

We welcome EDF Group / open source CloudCompare to our Supporting Partners List.

September 21, 2012
In the article "Non-profit launched to advance open source point cloud processing" from Spar Point Group, Radu Rusu, president and CEO of the newly created Open Perception, was quoted as follows:

"Rusu said Open Perception, pending a funding source, would also be taking on the libE57 effort, which creates open source software for managing files that adhere to ASTM’s E2807 Standard Specification for 3D Imaging Data Exchange (generally known as the E57 standard). He said of the current E57 standard, “there’s a lot of promise here,” and pledged Open Perception’s full support of the standard going forward, though he expressed some disappointment that E57 isn’t a working format and that it’s more useful for transferring, storing, and archiving data than anything else."

“But you have to acknowledge that things before E57 were very bad,” Rusu said, “with every hardware manufacturer having a different format. And just getting these companies to agree on something is extremely hard. It’s a very good first step.”

September 19, 2012
Allpoint Systems has announced that in release 1.1.2 that they will support E57 in their automated registration (Scan-time), web collaboration (Insight), and Mobile LiDAR (Perception Engine) products. We welcome Allpoint Systems to our Supporting Partners List.

The ASTM E57.04 sub-committee has approved the extension listing process. One of the greatest strengths of E57 is that it was designed to be readily extensible to accommodate new hardware innovations. This will allow extensions to be listed and documented for all E57 users. See the Extensions page. See LiDAR News item ASTM E57 Data Interoperability Update

September 14, 2011
There are a couple of positive developments on the adoption front that have happened this week – very exciting. Pointools has announced that they have implemented an ASTM E57 read capability in their POD Creator software and Riegl is looking at a November time frame for their ability to write the E57 format. In the case of Pointools this will also provide Microstation users with the ability to read E57 files as they are the Microstation point cloud engine. The momentum is starting to build for the use of the E57 data exchange format. Please continue to ask your vendors for their support. See LiDAR News item ASTM E57 Data Exchange Format Update.

July 6, 2011
The specification of the E57 file format for 3D data exchange includes a variety of capabilities that may not be relevant to every software package or hardware device that intends to write or read E57 files. The ASTM E57-04 sub-committee on Data Interoperability has divided the capabilities of the E57 format into a small set of disjoint features that a software package may choose to implement or not implement as needed. To maintain consistency across software vendors and to minimize confusion by customers and users, we recommend that every vendor use this naming convention to report whether their software supports each feature. See Feature Categories.

June 2, 2011

ASTM E57 3D imaging committee will have a table at the main SPAR conference on March 21-24 in Houston. Come and talk to us about your concerns. Also come join us on Thursday morning for the session called "Standardizing Data Formats" where the E57 standard and LibE57 implementation will be discuss.

March 1, 2011
Reported in the LiDAR News on February 27, 2011: "There is good news to report concerning the recently approved ASTM E57 3D imaging data exchange standard. First the actual standard itself will soon be available from ASTM – the American Society of Testing Materials. I believe the standard is No. E2807, but check the website to be be sure.

Just as importantly, I am pleased to report that a number of major vendors including Intelisum, Trimble, Leica, Optech, Faro and Pointools have all confirmed that they are in the process of implementing support for E57. For those interested in learning more about the reference implementations being supported by the E57.04 subcommittee.

In addition, both the GSA and Fiatech are considering adopting the use of E57 as the required data deliverable format. This will certainly be a major step forward for the industry."

Feburary 1, 2011
A new release of the libE57 (version 0.3.123) is now available to download. This version will generate the V1.0 E57 file format as approved by the ASTM standard E2807.

January 13, 2011
The revised E57.04 Data Exchange Format Ballot has closed with no negatives. This means that the ASTM standard E2807 is now approved. The standard should be published in the next 2-3 months. Again let's thank all the folks who have helped this process along the way.

January 5, 2011
We have written a paper describing the design and implementation of the E57 file format, which will be presented at the upcoming SPIE Electronic Imaging Science and Technology conference (IS&T) on January 24th.

January 5, 2011
The revised E57.04 Data Exchange Format Ballot is again posted on the ASTM web site. The ballot will be open and available on the web until January 10, 2011. Please Vote.

November 3, 2010
The ASTM E57.04 Data Interoperability Committee has found a fundamental flaw in the storing of the intensities and color information. The standard needs to be modified to add two new structures for the bounds on intensities and color values. Hopefully, this can be corrected before the ASTM E2761 standard is published. Look for an update in the libE57 library shortly.

August 31, 2010
The E57.04 Data Exchange Format has received official approval as a standard (known as ASTM E2761). The ASTM E57.04 Data Interoperability Committee has worked more than three years to get to this point. Let us thank all the folks who have helped this process along the way.

July 21, 2010
The E57.04 Data Exchange Format Ballot is now posted on the ASTM web site. The ballot will be open and available on the web from July 21, 2010 to August 20, 2010. Please Vote.
