Augmented Reality Welding Helmet Prototypes How Awesome the Technology Can Get

While Google Glass has gotten a lot of press lately for doing augmented reality for consumers, there’s a great deal of other applications that require an augmentation of human vision.

One such application is welding: a bright light sits in front of the welder as high energy flame or electricity is used to melt molten metal in order to glue together two pieces of metal. Obviously, it’s very hard to see the point of welding, even with the darkened lens of the protective welding helmet; but with computer-aided-vision it’s possible to make the weld points highly visible and easily accessed by the welder.

Add on post-processing technology to the augmented reality interface that can identify the welding apparatus, the weld point, and the molten metal and an assist-display can be added that could help the welder keep the joint in view using temperatures and best-fit scenarios to make sure that it welds properly. In fact, with the right sort of equipment, the heat emanating from the joint could be used to determine if the weld would hold after it was completed by watching thermal dissipation.

This is what the EyeTap research team at the University of Toronto is going for with their HDR imaging augmented reality welding helmet (presented at Siggraph2012):

Our “WeldCam HDRchitecture” (abbreviated “HDRchitecture”) system uses one or more cameras, and optional active illumination systems, that can be used by welding schools and professionals to inspect welding in real-time. We present HDRchitecture as either a fixed camera system (e.g. for use on a tripod), or as a stereo EyeTap cybernetic welding helmet that records and streams live video from a welding booth to students or observers, nearby or remote. By capturing over a dynamic range of more than a million to one, we can see details that cannot be seen by the human eye or any currently existing commercially available cameras.

Yes, the wearable helmet prototype looks like something out of a science fiction horror (that’s the nature of cameras and a lack of a face) but it’s better that cameras are mere inches away from that powerful blast of heat and not an actual human face.

As part of the demonstration video, it’s shown that this HDR technology could even be used in everyday situations to enhance vision in bright light situations and even in dim light. No doubt, as processors and video cameras get even smaller, Google Glass may become a potential secondary technology to use this same sort of concept. I imagine that we might even see low-light goggles that function as glasses (or visors) instead of heavy over-the-face bulk wear if this sort of technology can be properly miniaturized.

The technology behind these welding goggles is actually quite impressive and it has a lot of applications beyond welding. Especially the HDR augmented-reality enhanced vision portion, which could be useful for miners, divers, and even rescue workers such as fire fighters by allowing the enhancement of environments that are murky, filled with smoke, or too bright to see in. I especially see this being useful right now in these professions because they already wear bulky equipment that potentially covers their faces and the encumbrance of the current technology would not be a burden to them.

In the consumer sector, we probably won’t be seeing a technology quite like this except in the fashion of augmented reality via the Google Glass project or the Kinect Glasses from Microsoft (situated in eyewear) that will be less likely to augment vision to see better, but more to augment vision to gather and display metadata. However, as I said above, there are definite applications to help people see better in the dark, or even while driving to act similar to the prism in the rear view mirror to reduce glare and increase visual acuity.

  1. Well Kyt, I think this proves technology keeps on getting more and more awesome all the time! Augmented reality has so many possibilities, it’s not even funny!  Thanks for the great article.

  2.  @MostDarren I really enjoy finding things like this. Certainly the Google Glass project is going to be taking most of our attention (it’s not just cool but it may be in the consumer sphere one day) but every industry has something it could benefit from when it comes to augmented reality. Now, I didn’t initially think welding when I thought of augmented vision; but, hell, I’m going to take it when it shows up in the news.
    Thanks for the comment!

  3.  @Kyt Dotson My pleasure, Kyt!  I look forward to reading more of your articles.

  5. There is a lot of infomation regarding blogs i need some time do all that.

  6. There is a lot of infomation regarding blogs i need some time do all that.

  7. This is a smart blog. I mean it. You have so much knowledge about this issue, and so much passion. You also know how to make people rally behind it, obviously from the responses.

  8. wonderful piece of information Admiring the time and effort you put into your blog and detailed information you offer! I will bookmark your blog and have my children check up here often.

  9. I am very happy to read this. This is the kind of info that needs to be given and not the random misinformation that’s at the other blogs. Appreciate your sharing this best post.

  10. I have seen one another website. It’s so good. I have found that website which are selling very good kind of <a href=” http://www.wholesaleweldinghelmet.com/”><b>auto darkening welding helmet</b></a> and on very competitive prices. Plus they are USA based company. Have a look at the site and you will find some interesting facts on that website too. <a href=” http://www.wholesaleweldinghelmet.com/“><b>auto darkening helmet helmet</b></a>

  11. Thanks on this article, I really like the way you laid all the information. It is well written and very informative.

  12. Everyone should adhere to this perform circulation. Thanks for sharing:)
