I’ve been involved with photogrammetry for 8 years and have tested various close range techniques. Photosynth is a new avenue to explore & I’m interested in how it could be applied in the use, recording and accessing of heritage.


Cameras used in the synths: Canon EOS 1DS MkIII, Konica Minolta Dynax 5D, Canon Powershot A640, Nikon Coolpix 5400. Ricoh Caplio 500SE, Canon 60D

What a wonderful synth. It's great being able to move between the rooms, visiting the little cubby holes, cupboards and the UKs (maybe Europe’s) oldest loo. It would really improve the synth if the signs were added as highlights. Thanks for posting it.

Hi JCCW, very interesting synth! Are you allowed to walk down to the bottom? It'd be nice to see close-up high-res photos of the various signs and plaques on the ground, and also to see the village from the ground level and all the different dwellings interiors and walls. Thanks.

Nathanael (Over 1 year ago)
Lost, I'm surprised that I never commented on this inspiring synth. You certainly challenged me to try larger structures and I'm sure you did the same for others. I wonder if the inner and outer walls could be tightened up by adding a short orbit of the left and right sides of each doorway at minimum and possibly the same treatment of the top of the doorway as well. I know that means more photos which is a problem, but I'd love to see it done. Looking forward to your coming synths when you next have some free time.

Thanks blaise, I struggled to upload the pictures (out of memory errors) since then the software has been updated so I might retry a large upload again. I also wish I had more time this summer for shooting pictures but have been way to busy. Be glad when things slow down here in the triangle!

For what it's worth, Ed, I'm glad you went with the full resolution photos on this one. When Photosynth introduces dense reconstruction this synth will shine all the more. If you know someone who has a computer with obscene amounts of RAM, you should try the original photos in Yasutaka Furukawa's PMVS2 by using Henri Astre's PhotosynthToolkit. If you don't have the originals anymore, you can download original resolution copies of the photos with Henri's PhotosynthTileDownloader.

kration (Over 1 year ago)
Good suggestion re. the highlights Nathaniel - I'll work on it. In defence of the graffiti highlighted by Nathaniel, this is a tribute added by the owners of the land to their family, and has always been done in a way that is respectful to the site. Indeed, tributes like this from the land owning family date back a few centuries and are part of the sites history and interest (though my photos only show the most recent tributes). Compare this to the more scrawled carvings - though even the more impulsive graffiti has it's own history too. The fact that the family which owns the land then lets the general public enter and explore the site is to their credit. The site will also be closely controlled by governement bodies such as English Heritage and I'm sure that any carvings such as the highlighted ones will have been subject to detailed government scrutiny.

sir ivar, do you have any laser scan data to compare? I was involved in a rock art project for 3-4years and this involved scanning several carved stones. I might be able to get hold of the data. I’d need to capture additional imagery for a comparator synth though, we just have photogrammetric stereo pairs and the resultant point cloud wouldn’t be dense enough. I’ve not worked directly with Jim Chandler, but he did advise the above project and calibrate the cameras. Some of the projects work fed into his research on low cost photogrammetric approach and camera calibration. Is the email on the You Tube movie still current? If so, I’ll drop you a line. Cheers Rich

sir_ivar (Over 1 year ago)
PGRic, I've been pretty happy with how it has turned out so far. I'd like to compare the synth point cloud to a laser scan to compare accuracy. I'd love to see your work. Maybe we can compare notes. Are you working with Dr. Chandler by any chance?

PGRic (Over 1 year ago)
sir_ivor, hope you don't mind, but I've copied the link across from your Meyers Spring synth: http://www.youtube.com/watch?v=9-sjaUjrTnw I’ve been involved in recording UK rock art for about 6yrs, the last 3or4 helping to develop close range photogrammetric methodologies. I’m just absolutely blown away by your work here – I thought extraneous points within the cloud would prevent an accurate surface being produced. Many, many thanks for this.

Douglas, I’ve just spent 45 mins wandering around your synths - truly wonderful experience. In addition to Tony’s info, you could try the camera on continuous shoot walking around slowly. This seemed to work for me on this extensively carved outcrop: http://photosynth.net/view.aspx?cid=ebd36c16-1e7a-467c-8ff2-d6b99f14e4c8 . You’ll probably only need every 3rd or 4th image to stitch/synth correctly (depending on camera and write speed) Look forward to seeing more of your synths. Rich

TonyErnst (Over 1 year ago)
Oh, and have you discovered our new highlights feature? Check it out.

TonyErnst (Over 1 year ago)
Dounglas, We here at photosynth love what you're doing to document these archaeological sites. I would suggest that you start with wide angle establishing shots. Stand in one place and shoot a 360, taking a photo about every 10 degrees. Then, for the petroglyphs, and other things you want to preserve detail on take a "medium" shot the foucus on just that particular rock face (or whatever). Then get in close for detail shots (how cool would it be to have a detail shot for each individual petroglyph?). Now move 15-20 feet in another direction and do the same thing. Keep doing this until you've completed a circuit of the area. Make sense? Feel free to contact me if it doesn't. Also, you might try shooting closer to sunrise or sunset, the less direct light will bring out more detail, of course this won't work if half of everything you want to document will be in shadow. Anyway, great synth. Keep them coming! Tony

EdLee (Over 1 year ago)
madeeds, the tunnel's slope may not be accurate because photosynth does not have enough infomation. For example: http://photosynth.net/view.aspx?cid=c8063fc8-145b-4b42-936f-58ca7724b26d If you rotate the Courthouse so you are looking down at the staircase and the 2nd floor hallway from the top, you'll see they don't align with the outer walls of the building and the tunnel. I don't have the building's blueprint, but I am guessing in reality, the staircase and the hallway align perfectly with the building walls. The reason they don't in the Point Cloud is that the synther does not have enough information, same as with the tunnel here. So for example, if there is one photo that simultaneously captures a Courthouse exterior wall AND the interior staircase; or, for this synth, one photo that simultaneously captures the Adam Stephen House's roof AND the bottom of the tunnel, then the tunnel's slope may be more accurate.

madeeds (Over 1 year ago)
Fascinating story! I wonder why the synther thinks the tunnel slopes down steeper than it seems to in the pictures.

that you’re able to zoom in and see 4000-6000 year old tooling marks just enhances the experience immeasurably. Photosynth is also quite useful as an online Powerpoint Presentation, but with zoom as demonstrated here: http://photosynth.net/view.aspx?cid=4d2b1bf3-825f-499c-9392-9791d4e0decc The fact that you can see the rock art in different lighting conditions on the same synth is fantastic too (oblique lighting is best). I could go on about potential for heritage, but I best stop now Rich

PGRic (Over 1 year ago)
Hello K, firstly apologies to Artnowex for cluttering up his comments page & then to you all for waffling on a bit: I’m not quite sure what you mean by coverage, but if your talking about coverage with photography, then you’re not going to improve on the PS Photography Guide. Even though our project http://archaeologydataservice.ac.uk/era/ has pushed the boundaries for recording rock art using photogrammetry, the photography element is still fairly complex - having to think about each shot as a pair, optimal ratios between subject, and movement between base imagery + calibration etc it can be bloody awkward… On Photosynth = take you camera, take a shot, move slightly….wonderful. Admittedly, you’re not going to achieve the millimetre and sub-millimetre accuracies of photogrammetry and laser-scanning, but Photosynth certainly fulfils so many other needs, some of which you’ve stated. One of the biggest advantages is – surprise - the zooming capabilities, the fact t

K (Over 1 year ago)
PGRic that sounds really interesting. I'd seen a couple of your synths but hadn't read your profile. Maybe you can give us all some tips on how to get great coverage. Have you found Photosynth to be useful in recording rock art? I think it would shine at capturing the surroundings so you could see everything from the field level to the macro shots of the rock itself. Photosynth does compute the actual camera position so in theory we could glean the shooting distance from data we already have. We're not doing that now though so I guess it doesn't answer your question.

PGRic (Over 1 year ago)
K, it looks ammonite-ish. It would be interesting to know about focal distance given the numbers of photographs & point cloud density. For the past few years I've been involved in a volunteer project that helped develop close range photogrammetric techniques for recording prehistoric rock art. We could regularly turn out accuracies of 2mm surfaces with little data noise (1 – 1.5 metre focal distance), but a few volunteers pushed the camera calibration by getting really close (25cm) & as a result 0.5mm mesh were achieved. Worth a few tests me thinks...off I trot to find the camera :)

K (Over 1 year ago)
Good question PGRic - what's the scale of this item? and what is it? by the way, if you rotate the images before synthing they'll look better in 2D mode.
