Bib Recognition for Sports Photographers (Read 1552 times)

    Once the technology is in place, there are a lot of great options for it, just like you mentioned. There's even the possibility of having a photobooth at a race where people search for their bib# right after the race and print the photos an hour after they've finished. 

     

    This seems to me like it would be very popular.

    Well at least someone here is making relevance to the subject.

      Thanks Blaine and Larry.

       

      It helps to hear that I'm not insane, and others see a potential here too. I have a number of additional photog's to chat w/about it so we'll see how it progresses. So far so good, so thank you!

        Rob, this seems like a great application.  I would like to receive more information, as I would be a user and may also be interested in helping you sell this service in Brazil.   I just filled the information on your page, please, keep me updated. I will send you an email as well.

         

        Tks,

          Thank you hezrog, if you'd like to help out, a great first step would be providing valuable feedback on how you work now:  http://www.surveymonkey.com/s/FQKJX9H

            You can improve accuracy by fingerprinting the colors of the person wearing the bib. People generally stay the same colors while running a race (but not always). If you take it into account (e.g. Bottom=80% red, top=50/50 white/black) then you can increase confidence of candidate matches.

              (Even just noting the predominant color directly around the bib would help.)

                I'm at the RRCA National Convention and one of the breakout sessions I attended was on new revenue sources for clubs and a lot of the presentation was about race photography.  Some of the questions came about for how to match photos to email addresses and the predominant response was, "We don't do that."  So, I looked up your domain on here and mentioned it to folks. Hopefully a few sign up for your updates.

                  I did, thanks for the reference Blaine. I appreciate it. I've got about 4 more sign ups from interested folks!

                    MT, photo-red type systems use an actual human to verify license plate matches before anything is sent out.  I can't speak for every state, but I know the two I looked into both required that human check.

                     

                    True, but photo-recognition systems have advanced to the point where they can be used in police cars to scan all license plates around them as they drive to identify ones that are on the wanted list, or have not paid registration, etc.

                    http://en.wikipedia.org/wiki/Automatic_number_plate_recognition

                    At the end they mention that systems tend to be 90 to 94% successful.

                    So it does look like there has been a lot of automatic number systems out there for quite a while, they just don't seem to be used for races yet.

                      While quite true, they have a convenient set of restrictions available to them, including:

                      • Localization (standard length (and usually font)) of expected plates in the location.
                      • Standard colorization in the location
                      • The plate is almost always straight, or at a known angle.

                      On another downside, the systems are incredibly expensive. I'm not saying it can't work, just that I've never heard of anyone who has found it worthwhile. In fact I've heard the exact opposite.

                       

                      A specialized product for sports photographers can be optimized for the target market, just like license plate recognition has been. Each license plate photograph (or video often) is a unique moment. The chance of the car passing again is limited. A set of race photographs tell the race story. The same person will most likely appear 3-10 times.

                       

                      The ability to utilize this entire set of data, coupled with:

                       

                      • Shirt/pants color near the bib.
                      • Facial recognition.
                      • Expected bib numbers.

                      Allows the application to pull out and tag the photos in a manner and higher confidence level than would have been possible with just the photo and no context.

                       

                      At least... that's the theory I'm working off of :-)
