How is the order of presentation set?
I have a question about play order. I am a research engineer in Autonomous Perception Research,
so I understand something of the gigantic task you are attempting and largely accomplishing.
CONGRATULATIONS! I also have a small "Public Service" family owned company that specializes
in outdoor field classes and a large environmental web tour site called the Dunbar Creek Project.
I am hoping to integrate you plugin into my site at:
http://dunbarcreek.info .
That said, My plan is to take photos, straight ahead along the trail, and then to take
either 180 or 360-full panoramas at interesting locations. All of my "Dunbar Creek" synths are along this vein. If you take a look at:
First Example
and hit the play button, you will get an Idea, at the start of the sequence, what I am trying to do. However, after just a few frames, the sequence goes
top side, which supprised me, since the sky was the last thing photgraphed in the 360-full panoramas. This particular set has images approaching and leaving the panorama origin. Only
some of these are being stitched in, I think because they are too widely spaced.
Another good sequence shows in:
Second Example
Where there is a sequence of several photos, starting with one photo before the one with my
shadow, to the bottom of a downward slope of the trail to the stream. Your recommendations are to
move 1/2 the distance to the subject. I had figured that to be about 10 paces, but these segments
that work, are at about 5 paces. I realize that I am throwing ridiculous amounts of highly chaotic
data at the system, but am impressed that most of the time, it makes a reasonable attempt at
assembly.
How about adding a "Help the stitch" capability, for when the algorithm misses an "obvious" connection?
Thanks

I have this question, too!

Inappropriate?I saw elsewhere that the system assumes you have not renamed your files, i.e. that alpha-filename order matches the time sequence.
It's a bad assumption, but if true, it means we have real control over the playback sequence!
Did you rename your files by any chance? If so, try again, setting the sequence as you like.
I'm about to do the same with my current experiment :)
(I have a similar goal, perhaps WAY too ambitious: an immersive walk through an ancient bristlecone pine forest.)
I’m curious
-
Inappropriate?If the images were in their numerical order, They would work as I expected.
They do not. I think their order has to do with the feature matching sorting order
or something like that. Perhaps it is possible to reorder them in the supporting
files, later, but I don't know how to get to that data to correct it. I may end up
just writing my own, application, so that it does what I want it to do.
Thanks
Still waiting for guidance.

I’m Extreemely Happy, but a aware that I may be disapointed
-
Inappropriate?The ordering used for slideshows uses feature information. You can use '.' key to go through in the order the images where added to the synther which is normally alphabetical.

this answers the question

Inappropriate?That is EXACTLY what I was looking for. Might be nice to have an on screen button
that does the same thing, How about a link from Synth to Synth?
I’m Even Happier!, with high expectations!

Inappropriate?I'm working on the same idea to see if there is a difference. If you look under the What Features Should We Add to Photosynth
The challange is renaming 60+ images I wrote a little application to help. I'm working on a zone or group idea representing each distance from the subject. As you pointed out you have pictures at 5 paces and some at 10 paces. These would be Group A and Group B. The challange is that if you are at 10 paces and decide to go back to 5 then back to 10 then the pictures are out of order.
This is all in theory. I'm working on some test. I will point out and others can confirm or deny but I think your subject might be in question because of the textures. Look at the PDF guide. Page 7 shows a single tree (good) instead of a bunch of trees (bad).
The Photosynth Photography Guide (1Mbyte pdf)
Another thing is to study the master or grid view [~]. -
You misunderstood what I meant by 5 and 10 paces. I am talking about taking 5 or 10 steps along a trail and then shooting a forward shot. Then, taking another
5 or 10 and shooting another. If I come to an obvious occlusion point, I also take a
shot. Then, when I reach a point of interest, I take a panorama. I am beginning to
think, that it might be better to shoot three at each step, but I am not sure if that would help, unless the sides fully connected with the previous locations associated shot. As I said at the head of this thread, I fully understand that what I am attempting, greatly pushes the envelope of the feature selection algorithms,
because forests are so chaotic. I did read that in the manual, but I knew that
already. I work in robotic vision research for my "real" job. I am generally impressed with the feature matching of Photosynth. I only wish there was a capability to "supervise" (click on matching points) on disconnected synths. -
Inappropriate?Just got finished. I don't know the results yet hot our of the oven.
Here is the one with out sorting.
No sorting right from the camera (FireMantel)
Using the sorting application and grouping.
Sorting using Synth Renamer (FireMantel001)
I also noticed the image used on my home page used two different images.
My Home Page. If you look at FireMantel001 w/sorting compared to FireMantel you will see the thumbnail image is different. -
You have a very interesting point cloud developing there! Pretty Impressive! -
Inappropriate?I got ya, I think the "Rule of 3" might be along those lines. If I understand now, it is when you go from lets say looking/walking forward but the point of intrest (poi) is on the right of you. How do you go from forward to the right. I think the texture matching is based on a texture appearing in at least three or more different images. I start to shoot pictures to combine objects together as I rotate until reaching the POI. Making sure object A (somthing in front) and B (half way to poi) are in the same shot then B and C (POI). Then I can focus in on C. This might require like 8 to 10 pictures. I Just start taking pictures to make sure that I have an object in at least 3 photos each time I rotate. Like you say "take three" if not more. I know it kills the upload time but the more the better. Am I closer?

Peter:
Over the weekend, I got a synth to load that behaves pretty nicely in a path follow, like I am trying to do. If you look at:
Dunbar Creek The Meadow
Click on the first leaf, to bring up the grid of images presentation.
then double-click on the 6th image in the 4th row.
Now, if you click on the Up-Arrow key, you will walk across the meadow, and
if you click on the Down-Arrow key, you will back up across the meadow.
You can click Left, Right-Arrow and the up and down icons in the image, to look around, but it is difficult to get back to the path, except by trial and error,
where you find that if you are within overlap of the path photos, when you hit the Up or Down-Arrow, you will jump onto the path and be able to follow it
backward and forward.
It would be nice to be able to set the home position to a particular photo.
Thanks
Gary
I’m VERY VERY PLEASED!

Inappropriate?All:
ACTUALLY! after testing the link in the above message, and observing that it immediately took me to the correct starting image, I realize that the key is for your approach to be from far enough away so that its position in the forward moving stack is clearly in front of the other material. Now, if we only could
link from synth to synth or from synth to html page, that would be FABULOUS!
Thanks
Gary
I’m Feeling better all the time!
