Laser Scanner Standards

  1. The ASTM E57.04 Data Interoperability standard will be balloted in the next 30 days.
  2. A beta test program is going to be announced at SPAR.
  3. The test methods subcommittee is considering a shift to performance specifications.

Having just returned from the ASTM E57 3D Imaging biannual meeting I wanted to share a couple of items. First the data interoperability standard is scheduled for its first internal ballot within the next 30 days. We are hopeful that this will go smoothly as we think we have been keeping everyone informed during the 3 year process leading up to this milestone.

In addition we are also making excellent progress on the API and reader/writer reference implementations. Although related, this is actually outside the purview of the ASTM. We are in the process of setting up a beta test program for those companies interested in getting involved early in the adoption process.

Our plan is to circulate an information document at the upcoming SPAR conference in Houston, TX (February 8 – 10). If your company is interested in participating, and you are not going to SPAR, please send me an email and I will get you the info once it is available.

The other major news comes from the Test Methods subcommittee. This group has the daunting task of creating standard tests which would allow end users to compare the performance of laser scanners. A new approach was recommended that would shift the emphasis from forcing all scanners to be judged by a prescribed test method to validating the performance of a scanner against the manufacturers claims. It’s a shift from a test method paradigm to a performance specification. This seemed to make a lot of sense to many of us.
