this I can not prove: my Autopano (V1.4) has no holes when slanted.
I´ll give it another try and report later. But me and another felow stitched it with the mentioned method in Autopano: no zenith hole and no nadir hole. Which was expected to be. Talking about slanted images though.

You (and John H and Hans N) are right - I was just too careless about checking the default circle crop - I hadn't adjusted it! - with just a little adjustment of the FE crop it stitches just fine in APP v1.4.2 with no zenith or nadir holes - although blending at zenith was not great using Smartblend(which is what I would expect).

When I shoot with a Nikon DX sensor camera and Sigma 8mm on my NN5 head I usually shoot 4 or 6 around at +5 degrees. This gives good (better) zenith coverage, stitches easily, is simpler to level and the nadir hole is no larger than the rotator of my NN5 pano head, which is neither here nor there whether or not one chooses to edit the nadir.

The only 'point' I can see for a slanting technique would be to obtain 360x180 coverage in just three shots (rather than your 4 shots) which is what the Agno's MrotatorC head (I'm told one can do it with their RingTS8 head too)which provides both slant and tilt is designed to achieve.

Seems to me there are simpler techniques if one is going to take 4 (or more) shots.

Sorry, Hans - no!

I´m using APP as well as PTGui. Both on a G5 DP 2x2GHz, 8GB RAM.

I use PTUi only (!) when it comes to geometrical very structured pictures. APP in this cases does quite "too much" - instead of putting CPs on clear structures it puts them between them, where ever it finds subpixels and so on. Setting detection-quality to "low" helps almost in every case.

Speed is - in my feeling - better in APP as it is in PGTGui - definitely not less!

One (!) of the points i hate in PTGui is it´s refusing pictures which size differs only one or two pixels from the others. In my eyes that´s not acceptable - because i do some preparations in PS or Photomatix before stitching.

PTGui is a very good stitcher - no question. It has it´s place and i like it too. But APP in my eyes is the "next generation" . .

Especially for highres-stitching and perspective-corrections and so on.

I know it works also in PTGui - but less elegant i mean . .

If you have PTGui Pro - what is the reason you don't just use that software package to take care of it all. Ideally - PTGui Pro should take care of all blending and stitching
as one smooth operation (depending on how 'hands-on' one wishes to get).

i too prefer to blend my images first as the stitching and fusing each go faster this way, it's faster to fuse 24 small images and stitch 7 or 8 than to stitch 21 or 27 and fuse the 3 planes afterwards. to me the stitching is close to the last part of the process.

i too am using a d70 too and a 10.5 fish - pdxvr.com

have you figured out why you are getting blurry results yet?

Re: PTGui Viewpoint optimization>

2008-05-14T07:43:33Z

Hamish, I've seen PTGui (and the Panorama Tools optimizer) produce all sorts of bizarre results. Most commonly this happens when starting from scratch, with the images all assigned the same y,p,r values by default. Generally, you have a pretty good idea of what the values should be (and also the lens parameters) from previous projects. To me it seems perverse to deliberately withhold all this useful information from PTGui and then fret and fume when the optimizer fails to deliver the goods. I always either apply a template to initialize the project with sane values, or quickly enter rough yaw and pitch values on the image parameters tab, making use of Fill Yaw and updating values by column selections. When this is done, I find bizarre results are very rare.

FC-E8 is what they sell. Don't see many FC-E9's on eBay and I look a lot -- I think an FC-E9 just sold for over $400 bucks so you probably should buy them yourself and make a couple of bucks.

Since you already have the camera, all you need is a fishey lens and a rotator.

The Sunex 5.6mm would be a good choice for high quality real estate tours, understanding that real estate tours are usually of lower quality than say hotel & resort tours. The lens and rotator total $1000 and produce full 360°x 360° spherical images from 3 fisheye shots.

The work would be a very noticeable improvement over the Nikon Coolpix 5400/FC-E9 combo I use for real estate tours

If you search for "sunex" on this forum, you'll find a very long discussion when Sunex announce the lens and some links to samples they have online. Even downloadable souce photos you can test stitch

The Sigma 8mm f/3.5 is one of the mainstays of higher quality virtual imaging. Its US$600-630 depending on where you find it. A Nodal Ninja 3 would be about US$225.
With a 10-15° tilt up on the Nodal Ninja, you can get almost a full 360°x 360° image with 4 shots. There will be a small "hole" at he Nadir (south pole) where the tripod will be in the stitched image.

Note that 360Precision is going to release their Atome for the Sigma 8mm in a month or so and if it live up to its pre-press, you won't have to do any adjusting to set the No Parallax Pont. I think its suppose to be about US$300.

Either one of those options will stay within you budjet and be faily simple to use.

got a link ?

i'm guessing that you either have windows backslashes \ instead of the proper forward slash /

or your link is relative to your document on your computer and not relative to the document's location on the server.

but a link or your code would tell all.

Re: 'Tour' of small objects>

2008-05-13T21:11:37Z

Hi, Jorgen! Actually the technique is to shoot images with the camera fixed on a tripod and move the vase placed on a turntable in front of it. Search "turntable" in this forum and you will found a topic recently posted. I personally use an old recordplayer rebuild for this purpose. I placed a round piece of plywood with marks made on it every 10 degrees. A device fix it in each position so I can repeat it for making multirow object movies. That means when you edit the images you can obtain different movements of the object moving the mouse not only left-right, but also up and downwards. Regarding the software I use Pano2QTVR Pro.

Hi, does anybody know how to apply PTLens corrections on multiple files using XnView, mean to batch convert with xnview having ptlens CA correction applied on each file (tif)
I managed to call PTlens from XnView as PhotoShop plugin but only for a single file at the time.

thanks,

Rotational panoramic cameras are not very sensitive for the entrance pupil.
Actually most of them do not at all use it for rotation.

As the width of the area scanned is very small you do not get any parallax problem.

Only Panoscan seems to have a rotation close to the front of the fisheye.

Spheron is not rotated at the entrance point.
