Topic: Stitch / Stitch 2.0: Dig up the old panorama photos

I restitched one of my old pictures that had a horrible bend in it and 2.0 fixed it. I was quite impressed.

Topic: Stitch / Stitcher Errors and Ideas

To bkaylor: The older versions of Stitch, e.g. Stitch version 1.0.x, had a “bananapan bug” that would sometimes cause the stitched result to come out curved like an arc or rainbow or banana. Perhaps that was the cause of the “stitched as a wide curve” result you saw, in some tests. That bug was fixed, as far as we know, by Stitch version 2.0, which came out in March 2012. If you share a link to your stitched result, or send a screen shot of your input image grid to customerservice@gigapansystems.com, we could take a closer look at it.

About the alignment algorithm: alignment must strike a balance between assuming regularity of pan and tilt (which usually results when using a GigaPan panohead – unless it gets bumped, or the wind is strong, or objects in the scene move, or …) and aligning image features (finding corners, spots, and other visual features in the images and aligning them). Typically these two goals pull the alignment in the same (correct) direction but occasionally there are near-periodic image features in the scene, such as windows on a skyscraper, or tiles on the roof of the Sydney opera house, that cause our current algorithm to mis-align things.

To Phil Hotten: I think the alignment problem you were suffering was due to the near-periodic (almost-repeating) image features in your input images. I couldn’t tell what version of Stitch you used there. If you have Stitch.Efx, try its Save Projected Images feature, plus Photoshop or similar image editing software, to patch that gigapan by hand.

Topic: Stitch / Stitcher Errors and Ideas

I have a picture that has a part that is always misaligned no matter which version of the software I use http://gigapan.com/snapshots/280693/comments
Not what sure what the problem is though. The pictures are individually perfect, it just does not stitch right.

Topic: Stitch / Stitcher Errors and Ideas

I would like to see some discussion on a common error: a perfectly aligned row (or column) of photos stitched as a curve or rotated completely out of alignment.

Here’s one scenario: I shot a Dallas city-scape with a fair amount of sky between buildings. My Epic Pro took 462 photos in perfectly aligned rows and columns. All settings were manual, I had a level surface, the grid preview looked beautiful. The stitched result looked like a Picasso. Portions of buildings were turned 45 degrees, the entire top border sagged downward as if it were melting. A frustrating result after the time it took to stitch 4gigapixels.

I examined the errors by stitching small portions of the overall gigapan. I tried stitching the top row of photos by itself (~30 photos). This row was shot perfectly level thanks to the Epic Pro, but always stitched as a wide curve. Where each photo blended there was a vertical jump resulting in a saw-toothed top and bottom border.

Stitching several rows together yielded more strange results, like S-shaped curves. It seems that the Stitcher attempts alignment without regard to the horizontal (or vertical) integrity of each row. This is useful for hand-shot gigapans where photos don’t line up perfectly, but it also seems to ignore the precision and purpose of the Gigapan robotic heads.

I wonder if this could be an advanced option in the stitcher. A checkbox for “Maintain Horizontal (or Vertical) Alignment” in the case of precisely shot rows or columns. This might constrain the Stitcher to place the centerpoint of each photo in a row along the same line. Other options might prevent rotation of an image during alignment since the robotic heads provide identical camera angle in every shot. There is still some correction of lens distortion, but overall rotation may not be necessary.

These are just some thoughts, and of course user error might also be my problem. I would love to hear the developers’ thoughts on the stitching process and the variables involved.

Topic: General Gigapanning / App no longer working

Great work Jason, thanks for making that.

Couple of questions:
- Is there a way to go back to the panorama selection page after you have loaded a panorama?
- On my ipad it seems to scroll around the pano based on the ipad tilting is this a feature (that can be turned off) or a bug?

Thanks again for the nice browser, it looks great. A large dual touch screen is the ideal interface for interacting with gigapans so I love being able to see them on my new iPad.

Topic: General Gigapanning / Simple question

You can use the openzoom.org sdk to write your own software to view gigapans. We did this for the timelapse panorama system we built since we needed to be able to view time-series panoramas and collect data from them. We built our own capture hardware but we use the gigapan stitcher to stitch the images (since it can be automated) and then we wrote our own browser for viewing them. the openzoom tools let you write a player that can navigate the gigapan folder structure.

See for example the players here: http://gigavision.org

Topic: General Gigapanning / Share your mistakes!

So what does turning off image stabilization do?


Mistakes:
- Forgetting to turn off auto focus
- Not writing down number of images/columns (makes it hard to stitch 1000 images when a few in the middle are missing)
- Not paying attention and fixing it when the gigapan misses image halfwya through a 1000 image pano.
- Not eyeballing the horizon well enough and cutting off some crucial part of the image (http://gigapan.com/gigapans/106048)
- Not blocking the viewfinder so the image exposure is way off (see the black parts in the bottom left side of this one: http://gigapan.com/gigapans/104747)
- Trying to set overlap too low to reduce image count and ruining a huge image: http://gigapan.com/gigapans/88326 -although the new stitcher mostly fixed this image… http://gigapan.com/gigapans/101140)
- Driving 5 hours to southern Utah without the camera trigger cable for my epic pro.
- Leaving the trigger cable in the epic pro so I won’t forget it and bending it so it’s unusable.
- Forgetting the camera mount for clipping my camera into the epic pro
- Tripod in the snow and the legs are missing their rubber tips so one of the legs sinks in by the end of the pano and the tripod is on a total slant.
- Leaving the shoulder strap on the camera so it hooks on the tripod as the gigapan turns
- Bumping an epic 100 halfway through a huge pano so the whole head rotates way out of sync
- Camelback opens in the pack and fills both cameras with water (this was my friend who was I loaned my rig to so he could shoot a pano for me)

I could go on all day ;) The best solution is to just shoot tons of them so when you are shooting one that you really want to come out you’ll remember to do everything right.

Topic: Web Site and Forum / Following users

Thanks Angelko.

Ron, I agree, RSS for tags would be awesome.

Another good social feature would be a basic “like” button (either one that connect to facebook or an internal ‘thumbs up/thumbs down’ like youtube has). Being able to “like” a gigapan is a great way to measure how popular gigapans are and quickly post cool gigapans to one’s facebook page. (I know you have the “share” button, but clicking ‘like’ is faster and a quicker way to flag an image is good.) Even just an internal “thumbs up” or something like youtube has would be a great way to help users rate photos and let the good gigapans rise to the top.

Topic: General Gigapanning / straight

Hey Virtualnet,

You have to understand that a gigapan is a 2D projection of a curved surface, just like a map of the continents. You camera is focusing on a point that is a constant distance from you. As you turn left to right that point becomes an arc with you at the center. As you look up and down you create a vertical arc. You might imagine a gigapan as a bunch of post it notes (the individual pictures) all stuck to the inside of a big globe.

Every 2D map of the continents is distorted in some way because it used to be a sphere. Stitching programs make your spherical gigapan look flat by warping and distorting it; that’s why the straight wall in your photo curves like a banana. They give you their best guess at 2D, and you can always crop it or straighten it in Photoshop or Gimp.

All things considered, your linked picture has a very reasonable amount of bend at the edges. Hope that helps.

Please add the “2:3” “3:4” “9:16” to “Aspect Ratio” of “Export Option” of “Option” the firmware of Gigapan EPIC Pro. That way, I will be able to use the camera vertical. Method of representation is one more reason.

Hi all:

According to the listing online, the Epic 100 is compatible with the Nikon D7000. What it fails to mention, is once you put a lens on it, the camera is now to heavy. IS anyone using an Epic 100 and D7000, and if so, what lenses are you using?

Topic: General Gigapanning / Bubble of Gigapan

Hi, i have one Gigapan Epic Pro and i cant nivelate the robotic head.

Im making one panoramic in my house. I have one Manfrotto 055XPROB and i nivelate the bubble of the tripod:

http://img705.imageshack.us/img705/2753/dsc3740…

Now, i nivelate the Nivelator Plate of manfrotto (438):

http://img849.imageshack.us/img849/2257/dsc3741…

Now, i put one adaptor 3/8 to 1/4 and the Gigapan Epic Pro isnt nivelated:

http://img135.imageshack.us/img135/9654/dsc3742…

Now i move the Niveltator Plate to center the bubble of the Gigapan Epic Pro:

http://img853.imageshack.us/img853/3395/dsc3744…

BUT, the bubble of the nivelator plate now isnt in the center:

http://img191.imageshack.us/img191/7454/dsc3745…

And if i move the GigaPan Epic Pro turn arround and the bubble isnt center again:

http://img705.imageshack.us/img705/7940/dsc3746…

So, i make other steps.
I nivelate the tripod, i nivelate the nivelator plate and i put one manfrotto tripod head 808RC4 and nivelate the bubbles of the head manfrotto:

http://img138.imageshack.us/img138/4818/dsc3747…

http://img845.imageshack.us/img845/8392/dsc3748…

but when i put the Gigapan Epic Pro the bubble isnt center:

http://img577.imageshack.us/img577/9674/dsc3749…

So i center again the bubble but using the comands of the Manfrotto head 808RC4 and the bubble is center again:

http://img690.imageshack.us/img690/6129/dsc3750…

BUT, when i turn arround the Gigapan Epic Pro the bubble isnt center again:

http://img411.imageshack.us/img411/2976/dsc3751…

What im doing bad? or what im missing?

Thanks a lot!
