Do you have an idea for an awesome feature we should add… or hate the way we’re currently doing something? Share your ideas and suggestions here.
I've been working with this wonderful software to try to Photosynth the interior of a house. Being the lazy person that I am, I wandered around with a video camera and later split up that into frames. However, the results of the photosynth still contained multiple disjoint groups even when pulling out every other frame of the video, and left many pictures unclassified. Could a tweak be added that made the assumption that the entered images were sequential so that it might "try harder" to stitch subsequent images together?
Secondly, is there any way that underlying parameters could be exposed through an advanced tab or some such?
I have this same request for sequential images taken with a still camera. Aletrnatively that photsynth comes with a sequencing toolbox allowing the user to order the sequence - this is a noatbale problem with sunset synths...the sun often goes up and down instead of just down in the synth!
This has been discussed at some length at getsatisfaction.
MathMaestro, giving Photosynth too many images (even if they are the low resolution stills that a video yields) almost always gives poor results. A more likely solution is if we are given the ability to tag specific parts of individual photos to point out common objects in photos that fail to synth.
Fred, it's worth noting that if your images' filenames are such that the photos taken earlier come earlier when sorted by filename then you can step through a synth where time is important (a sunset synth) in correct order by using the fullstop/period key to advance and the comma key to step backwards.
The truth is that with all the EXIF data that Photosynth reads it should, by all rights, read the date and time that a photo was taken and give us a way to step through the photos in true order, rather than simply filename order. This is an important part of photography and Photosynth should recognise that.
The blur introduced when you move the camera seems to be the reason that a lot of photos didn't stitch. Maybe try with more light, or move slower. Slower movement will result in more frames, but maybe you could use every 10th frame instead of every 2nd frame. Please give this another try. I'd like to see it be successful.
thanks Nathanael - I will try this, but it would be nice for this to happen automatically when you hit the play button, or that we could control the sequence when doing the synth.
okay this has led to a renewed "viewing experience"...very good.
Fred, glad to hear this worked for you. We are agreed as to the need for 'authoring' tools to determine default synth playback for others, etc. and the Photosynth team has publicly acknowledged their desire to address that, but it's anyone's guess as to when we'll see them delivered. The list of features that they want to build is quite long and it takes time to get them up to Live Labs quality on something as complex as Photosynth.
Also, I should point out that a list of even more commands is available in the Photography Guide.
Visit the 'How To Synth' page ( http://photosynth.net/howtosynth.aspx ) and scroll to the end of the page to find the link to the guide. After opening it, scroll to the end of the guide to find the keyboard shortcuts. There's actually quite a few more options than the icons give you.
thanks Nathanael - I downloaded the PDF some time ago - but only picked up on a few of the commands...
Nathanael, thanks for the replies. I had actually originally tried every tenth frame or so, and had gradually reduced the number to every second frame, hoping the increase in material would allow stitching things together.
I think the blur is the main problem; I'm trying to use a camera to take video rather than a true video camera, so I need to give it more time to adjust the focus while panning.
Unfortunately, I cannot retake the video at the moment. Perhaps later...
