Topic: save the cloud of points in CAD format

Hello, let me know if you can save the model generated by Microsoft Photosynth in a compatible format for processing in a CAD program or use it to make even off-line.

Waiting for your answers or advice to alternative products because I need a representation for the thesis.

Greetings

Hi, Shaggy85,

The answer to your question is that your fellow Photosynth user, Christoph Hausner, has made a very easy to use point cloud exporter. You can download it from http://synthexport.codeplex.com/

More towards the CAD world, you can also look up Kean Walmsley's Photosynth point cloud importer for AutoCAD 2011 here: http://through-the-interface.typepad.com/through_the_interface/2010/04/importing-photosynth-point-clouds-into-autocad-2011-part-4.html

Credit goes to BinaryMillenium for being the first person to figure the point cloud format out and other people like the BIN to PLY people and Craig Dunn who improved on BinaryMillenium's very manual process, but Christoph and Kean have the latest and easiest solutions.

Christoph's exporter now exports the camera positions|parameters from the Photosynth JSON file, although they are only exported as a CSV file as no one has requested that they be be in a specific format. If you have a format that you want them to be saved as, you could ask him under the 'Discussions' section of SynthExport's site on CodePlex.

So far none of the exporters have tried to do anything with downloading the photos, themselves, though. It shouldn't be terribly difficult to save the tiles that make up the highest resolution of each image in a synth and piece them back together correctly, but no one has made the effort as the photos usually take up far more hard drive space than the point cloud and metadata files, not to mention that there would have to be something in place to stop people from downloading images from (c) synths.

Hope that helps you out!

Just as a note, this 'Announcements' forum is meant to be for the Photosynth team to talk about new features that they're putting out, so try to use the other forums, such as the 'Photosynth Lounge' to ask general questions or drop the Photosynth team an email at photosynth@live.com 

No hard feelings, but I thought that you'd like to know.
Cheers!
