Deep Wood House's South Lawn (Odds Half)

This is part of one of my synths that I've been trying to make work since the 8th of September. It's only a small portion of the grounds around the Deep Wood House in Salem Oregon's Bush's Pasture Park but it's a beginning.

Photosynth keeps running out of memory while analysing the full set of photos because they are all of things which generate a lot of 'image features' (the patches of texture in your photos that Photosynth matches to figure out how the camera positions and points in the photos match and relate to each other).

After trying fewer and fewer photos at one time, being forced down near to half the number of images, and becoming more and more irritated that objects featured in both earlier and later photos would not get the extra detail in the point cloud that they should if all the photos were together, I thought that if I had to make a synth with only half the photos, I would at least choose photos that were evenly spaced from the beginning to the end of my photo set.

I've now successfully synthed (97% 'successful' anyway - some annoying rifts were introduced in the point cloud because of missing every other photo in these 'half' sets) both the odd numbered photos and the even numbered photos as separate groups. Someone who had viewed one of the synths and later found the second might mistake it for the first one that they had seen and comparing the point clouds of both show that they are truly very similar but the detail and density of the point cloud that is lost because of missing the matching that should happen between the evens and the odds is very unfortunate.

If you're curious to see how the evens stack up, click here:

The main drawback is that, in that case, the sundial managed to escape the rest of the pointcloud even though it shares the same 'synthy' score.

Hey Nathanael. great synth! I'm looking at the overhead and it's really quite dense. I love the coverage that you got here. It also points to some possible improvements with the overhead view when we have a dense point cloud. very coool! i'm fav'ing this.

Thanks! It's a work in progress. =]

I really wish I could just get the entire set in one synth. That's the kind of density that I want to see.

I've got to stick around longer in synth collections like yours. How did I miss this one ? You did a beautiful job (as usual) on this one.

I mentioned to CharlPe that my second eldest son is coming down for the holidays. And my son is one of many people I have told about Photosynth. He, like everyone else, has not even attempted to check out this site. So, when he arrives, I plan to set him in front of my computer and force him to look at some of the amazing synths. I also mentioned to Charlpe, that within my "favorites" are synths which I know have that undeniable jaw-dropping effect. Among other's, and Charlpe's synths, yours will definitely be some of the very first synths I will show him. Hopefully, after seeing these synths, he might decide to take up synthing.

I just thought I'd pass this on to you.

I also have a younger daughter and older son I plan on "ambushing" in the same manner.
My wife?... She hates computers.
My dog? well you know... LOL

I'm honoured to make the cut, Jim.

If any of your kids has an iPhone, you should download the free iSynth Photosynth viewer for it. If you get the chance, check out Orbit Mode, as it adds a little twist on viewing synths you already know well.

The free Seadragon Mobile app is also very cool as an image browser. It's not at all 3D and there's no point cloud, but it does much better on zooming down to the last detail of every image in a synth. Although iSynth is cool, it doesn't do such a great job of letting you zoom all the way in on an image. Put the two together, though, and you have the entire experience.
