Clarification on feature, GPS in standard Photoscan?

[Mr Whippy]

Hi all,

I've been looking high and low on the website and documentation (and 'searching' the manual), but I can't find out if the standard version of Photoscan uses GPS EXIF data to help in aligning the image inputs.

Is this an automatic feature, or something I have to set specifically, or not even in the standard version.


I've seen it mentioned before and I was certain it was a standard feature but perhaps I'm just misremembering?



Clarification on the version features page might be useful for others if it is indeed not present in the standard version.


Thanks

Dave

Hello David,

Standard edition doesn't support any referencing instruments and GPS data cannot be used in this edition.

Probably you've confused it with some camera parameters derived from the image EXIF.

Thanks for the clarification!

I appreciate many users will make a lot of money from the DEM/DSM etc that they can produce with these features, so the pricing has to be high.



But for my requirements I just wanted to make sure that over many hundreds of images that there wasn't significant drift that was impossible to correct for. Ie, a strip of cameras may be 50m out over 10km.


I suppose I can just export many smaller chunks, where the total error over a smaller chunk is within an acceptable tolerance, and then align each chunk against reference maps chunk by chunk.
It's not ideal but it's a work around to make sure start/end points are correct I suppose.



It's a shame there isn't a Photoscan version at about £500 that has some better features to manage big data sets, drift, scaling etc, but doesn't impact the features in the pro version for people doing industrial/cartographic level work.



Thanks!
