Hi everybody!

I need someone that creates a panorama-machine for me. The thing is, because I already own all parts necessary, I need some german boy/girl/man/woman that best lives here around the area I live. Please drop me a line if you are interested in helping me out!
email: fg(AT)48design(DOT)de

If you don't live near Karlsruhe or Mannheim here in Germany please do also write me an email. That would be okay, too!

THANK YOU!


Ein paar Worte über das Projekt:
Ich möchte automatisiert HDRI Panoramen aufnehmen, am besten sogar mit Timelapse Funktion. Mir fehlt leider die Zeit und zugegeben auch das KnowHow um es alleine zu realisieren. Als Start in die Welt der Elektrotechnik ist das Thema wohl doch nichts! ;o)
Ich habe bereits ein Propeller Board, einen kleinen Touchscreen mit Board zum Ansteuern, zwei Motoren mit Controller Board und auch eine genaue Vorstellung des Endproduktes inklusive 3D Daten.
Die Hardware würde ich je nach räumlicher Nähe vorbeibringen oder schicken...

Liebe Grüße
Fabian

Was ist ein Panorama Machine?

Nettes Projekt, wie stellst Du Dir denn die Zusammenarbeit vor? Soll das Gerät dann am Ende komplett aufgebaut werden, oder willst Du auch was selbst machen? Geht's auch um Geld oder nur um den Spass? Gibt es einen Fertigstellungs-Termin?

Hi,

Propuser Clemens has a finished project PanoCam

here is the link to the thread

Thank you for all those replies in a relatively short amount of time!

@MagIO2
Ich habe null Ahnung von Elektrotechnik und nach PHP, ActionScript und MaxScript hört bei mir schon der Horizont auf. Daher wäre es mir am liebsten ich könnte die Hardware in vertrauensvolle Hände übergeben und anschließend zusammengebaut und programmiert wieder zurückbekommen. Ein Gehäuse drumherum zu bauen sollte ich hinbekommen. Mir fehlt zudem einfach die Zeit mich selbst ans Werk zu machen! Eine Deadline gibt es keine. Bei Interesse bitte per eMail melden, dann kann man auch über Geld reden.

@StefanL38
Thanks for that post. I already talked to Clemens but he is out of time and he by himself says he is not that professional enough to teach me how to do that.

It appears to me there are three main parts to the project:

1. Camera interface to allow the microcontroller to trigger the shutter and maybe adjust other variables.
2. The pano head which positions the camera so the axis of rotation is around the no-parallax point for the camera+lens+focus+f/stop combination.
3. The motor control to allow the microcontroller to rotate the camera as desired.

1 & 2 are somewhat camera specific, so you'd need to make it custom for your camera.

On the other hand, you can get great results with less than a full pano rig. (I've made some using handheld shots.) You just need to follow some easy rules:

1. Overlap the pictures! Stitching requires identifying common points between shots. No overlap (or no usable control points) means no panorama. A lot of guides recommend 20-30% overlap. I say find something on the edge of one shot and put it in the center of the next shot (~50% overlap) to give yourself plenty of opportunity to find good control points.

2. Rotate the camera, not yourself. (Otherwise you will have parallax errors with foreground objects.) There is an ideal no-parallax point somewhere in the middle of the lens, so the closer you get the better. Tripods are a good idea, but even a post or your son's head is better than nothing.

3. If possible, shoot a constant exposure, white balance and uncompressed (RAW) photos. Hugin can compensate (somewhat) for exposure & white balance and it's possible to make a good panorama from JPGs (heck even cameraphone pix).

@ericball
You are right. I have lots of thoughts on all that and also some (code) examples but I can't manage that because I'm a noob! ^^
1 & 2 are usable for lots of cameras with the right interface, I think. 3 is the easiest thing for someone who knows about electronics and the propeller chip... right? ;o)

I definitely need a full pano rig, that's why I need somebody to help me doing this. I already take HDR panoramas with a fisheye but it's not the best way to do that.

The hardware I got, for all those interested:
- Propeller Proto USB Board
- Touchscreen (PTP "Shield", www.rayslogic.com/Propeller/Products/PTP/PTP.htm)
- two motors with encoders (emg30)
- H-Bridge (L298)

Steps to be done:
- use Touchscreen to start/stop, timelapse de-/activation, bracketing and exposure settings
- USB remote cable for triggering cameras (nikon and/or canon via MTP/PTP)
- perhaps some IR connection for some other/older cameras
- adjustments of tilt and shift motor
- great would be some power adaptor and a good rechargable battery or maybe some solar panel charging *g*
- best would be to pack all those components into a "nice" cover (metal/aluminium) to fit on a regular tripod

The stitching of all those generated images is made afterwards by software (www.autopano.net/en/photo-stitching-solutions/autopano-giga.html)

Please send me an eMail to the adress above if you are interested in "making me happy"! ;o)

One thing to clearify: I need some guy from Germany only because it's a lot easier to hand the hardware over, get it back again and maybe learn something about how it is done. Having no clue about electronics AND learn it in English language is not the right way, I think. I don't want to discriminate against someone by saying "Germans only"! :D

All the camera specific parts can be tested when you build your camera turn-table. You operate it manually and then compose the images. Then you go to the ucontrolled version :). I'm not german but live a bit north from that area :)

Maybe I should have written "in Germany" and not "from Germany"... ;)

@Ale
Understanding electronic things in my native language is definitely much easier so my entry title isn't that wrong... ;)

By the way: if there should be more hardware to buy for that project I would not say NO... just contact me and we will discuss everything.

@MagIO2
Interesse?

@All
Wäre super, wenn sich eventuell noch jemand dafür interessiert! Das muss natürlich niemand umsonst machen, über den Preis möchte ich allerdings nicht hier direkt im Forum schreiben...
It would be great, if someone else would be interested in this project! And of course noone must do this without getting money, but I would not discuss this directly here in this forum...
