Motorized gigapixel pan head

by Paradise33 » Sat Sep 13, 2008 5:30 am

What a great automated pan head PanoBot http://www.emrichs.de/panoflexi/panobot-en.htm#Kosten and a very impressive 360 pan taken at 170 km/h http://gigapanbot.de/panogalerie/index.php?datei=bmw-160®ion=M%FCnchen&version=Quicktime Now that design has great potential!

Hi, I'm T. Emrich, the developer of the GigaPanBot
The PanoBot was the first automated head. The current motorized head is called GigaPanBot and you should find all information om my website.
Feel free to contact me if you have any questions.

Hi Emrich.
We are interested into supporting your head in our software. Could you make us a small resume of how the shooting is been done ?
( row major, column major, from top down or down top ). Can it be used only to shoot matrix way ? ( The other way is a list of location and shoot there ).
After the shooting, can the photographer get back a log or text file with a list of each shot coordinates or does it works like the gigapan without any log file creation ?

Hi AlexandreJ,
thank you.
I was considering and already started to save the head position of the head to a SD card and directly create a template to be used by the software to align the images. Currently I'm using PTGui, but looking forward to the new announced features of APP, I see some great advantages with APP related to gigapixel images.
So yes, for the future I plan to save the position (yaw, pitch and roll) of each single picture to an SD card.
Right now I move by row (left to right or right to left) with the option to always return to the beginning of the row or just go back and forth.
I can also choose if I want to start from nadir or zenith.
Bur for the next version I plan to be more flexible and also move by column.
The next will be to optimize the number of pictures for spherical panoramas.
Depending on the pitch I will optimize the number of pictures per row, so this will reduce the number of pictures needed to take a spherical high resolution panorama. So this means the software needs to be flexible to allow different numbers of pictures per row.
Looking forward to see the new version soon ;-)

Regards ET

Mr Emrich,

is it possible to control the GigaPanBot from an external device, through a serial or bluetooth link?

As you may know, I'm developping papywizard, a free (open source) software to control the Merlin/Orion astronomic mount, and use it as a panoramic head... Papywizard can be used to drive other heads, as long as a hardware link can be established...

Hi Frédéric,
no this is not possible.
All the software needed to control the device is flashed into the controller, so I don't need any additional hardware.
Of course I can use my controller too to control different motors or gears. As you can see on my web page this is a modular approach and I use one controller for different purpose.

Don't you think it could be a nice option to add a serial interface to control low-level stuff from anothe controller? This could give a great flexibility (modularity)...

If you are refering to a RS-232C serial interface, then this is not a good choice. It would be better to use an USB interface which is standardized, faster, and more flexible (tree configuration). You are able to buy inexpensive USB hardware modules that you can interface with your controller.

I don't agree. Serial interface is the most versatile one for embedded hardware: you can then plug any converter which fits your needs (usb, bluetooth, wifi...). PDA do not have usb *host* interface, only slave.

Wait until we will present our controller - uses bluetooth up to some distances. Adaptable to nearly all kind of heads and basic-programmable/editable at home or inthe field with presets of lenses, cameras, angles and so on - will store some hundred presets which you can select in the field by pushing one button (and which are editable "on scene" of course, if it has to be, via it´s touch-screen).
Initially built to control the Merlin - but as i said adaptable to DIY-solutions.

I think it will be ready as a prototype at the Photokina.

best, Klaus

@ AlexandreJ,
what file format or structure of the log file will APP expect?
Please let me know so I can prepare to code the function.
Is APP able to read the PTGui template?

GigaPanBot looks very interesting. Do you plan to produce these for sale?

Actually, we are supporting a lot of input format and because unfortunately there is no standard format for a panohead log file.
So, knowing a lot of them, I would suggest to use the papywizard format which is easy to understand and extensible if needed because it's xml.

Here's an extract of the papywizard output.
2 parts :
- header => stores the settings of the shooting, for the moment, we don't use it fully
- shoot => image and location ( you could have more than one entry for the same position when you do bracketing ).

Code: Select all
<?xml version="1.0" ?>
<papywizard>
    <header>
        <focal>
            17.0
        </focal>
        <fisheye>
            False
        </fisheye>
        <sensorCoef>
            1.6
        </sensorCoef>
        <sensorRatio>
            3:2
        </sensorRatio>
        <cameraOrientation>
            portrait
        </cameraOrientation>
        <nbPicts>
            3
        </nbPicts>
        <realYawOverlap>
            0.29
        </realYawOverlap>
        <realPitchOverlap>
            0.47
        </realPitchOverlap>
        <template pitch="2" type="mosaic" yaw="2"/>
    </header>
    <shoot>
        <image id="1" pict="1">
            <time>
                Sun Jan 13 11:48:49 2008
            </time>
            <yaw>
                -3.2
            </yaw>
            <pitch>
                -3.7
            </pitch>
        </image>
        <image id="2" pict="2">
            <time>
                Sun Jan 13 11:48:49 2008
            </time>
            <yaw>
                -3.2
            </yaw>
            <pitch>
                -3.7
            </pitch>
        </image>
         ...
         ...
    </shoot>
</papywizard>

Note that I changed the format a little bit, to support preset templates, and other minor things (I use more attributes and less tags). But the spirit is the same, with 2 parts: <header> with basic informations, <shoot> with all shooting positions. As said Alexandre, the header is not really usefull for APP, which only needs positions. But it is nice for humans ;)

Here is an example in mosaic mode, with bracketing:

Code: Select all
<?xml version="1.0" ?>
<papywizard>
    <header>
        <shooting mode="mosaic">
            <stabilizationDelay>0.5</stabilizationDelay>
        </shooting>
        <mosaic>
            <nbPicts pitch="1" yaw="2"/>
            <overlap minimum="0.25" pitch="1.00" yaw="0.58"/>
            <cameraOrientation>portrait</cameraOrientation>
        </mosaic>
        <camera>
            <timeValue>0.5</timeValue>
            <nbPicts>2</nbPicts>
            <sensor coef="1.6" ratio="3:2"/>
        </camera>
        <lens>
            <focal>17.0</focal>
        </lens>
    </header>
    <shoot>
        <pict id="1" num="1">
            <time>Wed Jun 25 10:37:16 2008</time>
            <position pitch="0.0" yaw="0.0"/>
        </pict>
        <pict id="2" num="2">
            <time>Wed Jun 25 10:37:17 2008</time>
            <position pitch="0.0" yaw="0.0"/>
        </pict>
        <pict id="3" num="1">
            <time>Wed Jun 25 10:37:20 2008</time>
            <position pitch="0.0" yaw="20.1"/>
        </pict>
        <pict id="4" num="2">
            <time>Wed Jun 25 10:37:21 2008</time>
            <position pitch="0.0" yaw="20.1"/>
        </pict>
    </shoot>
</papywizard>

And the header in preset mode:

Code: Select all
<?xml version="1.0" ?>
<papywizard>
    <header>
        <shooting mode="preset">
            <stabilizationDelay>0.5</stabilizationDelay>
        </shooting>
        <preset template="xxx"/>
        <camera>
            <timeValue>0.5</timeValue>
            <nbPicts>2</nbPicts>
            <sensor coef="1.6" ratio="3:2"/>
        </camera>
        <lens>
            <focal>17.0</focal>
        </lens>
    </header>
    <shoot>
...
    </shoot>
</papywizard>

GigaPanBot looks very interesting. Do you plan to produce these for sale?

A member of the Panoguide forum reports that Mr Emrich tells him that the component and material costs alone for the GigaPanBot are in the region of Euros 1,000 and that Mr Emrich plans only to make a few for friends.
