From most of the comments I must assume that most have not actually tried this program, as I have.

First you do have to shoot photos straight on as this program was designed to measure in a single plane. As far as accuracy I was able to scale overall measurements of up to 16 feet and be within 1/2″ of the actual measurement.

Now for the down side. I was using a 10.1 megapixel camera and the high resolution photos that were downloaded into the program were cropped on the right side by about 25%. So if you are using the program to get an overall measurement from an interior room wall photo you are SOL as the right side of the photo is not there. Even though the program advertises it works with all cameras, apparently it does NOT! The program doesn’t work well with high resolution photos. The manufacturer is aware of this problem. Additionally, storage and retrieval of measured photos is an issue.

The program is a good idea, but it definitely needs work and more features added to make it worth trying. I have to say I am amazed at all the editors that were willing to give this program a thumbs up without really putting it to the test.

Hey folks,

I’ve been following Iphotomeasure since it’s inception in November, and I’ve yet to come up with a straight answer on how it works. Having read more about photogrammetry and digital imaging than I care to, it seems to me that for someone with low accuracy requirements and point and click functionality, it’s not a bad deal. However, they claim they can measure to 1/32″ with the right camera a single point perspective, but I’m not convinced. I agree with the comments on perspective and barrel/pinhole distortion. If anyone has more detailed analysis, I’d love to hear it. FYI…they’re looking for investors. I’ll be curious to see if they Angel community feels as confident about their applied for patent as they do.

Re: everyone who wondered if it takes perspective into account: No, of course not! The makers of this software are complete idiots who never tried their product out in the real world! Duh …

Anyways, yes, you can do the same thing, and much more, in a multitude of other applications (Blender, Canoma, Photoshop, …), some of which are free. But they’re not specifically made for this simple task and harder to use, so I don’t think this app is not completely pointless. On the other hand, who can imagine a DIY situation in which it would really be worth its price? The “furniure shopping” use case is just a joke, it would be far more convenient to just take measurements manually, or look them up online. But for contractors … yeah I can see that. And as a business expense, 120,- is really not that bad, measuring devices with sharks and lasers also cost money.

Hmm, interesting but it would be much better if they could make a Cell phone app to do the same. Snap a picture with your cell phone camera and run in against this app. No need to wait till later.

And, er, iPhotomeasure guys – can I say ‘metric?’

It seems that in order for this to work, one would need a stereo picture. Meaning that one would need two cameras, a fixed (and known) distance apart, take a picture at the same time. Then I would believe that this would work very very well. Without stereo, I don’t see how it could accurately consider depth.

“I impressed the Home Depot folks…”

Yes, whenever I go there, that’s what I always strive for, too. Makes my life complete.
