Re: [Elphel-support] NC393 Cameras rebooted unexpectedly [SEC=UNOFFICIAL]

[Olga Filippova]

Norman,

You are right - it is difficult to judge the reason for reboot after
reboot. How often does it happen? You may also run
http:///hwmon.html
and leave the page open to see the temperature. As it happens on two
cameras it is not likely to be a hardware problem, so I would also suspect
PoE switch. Easiest thing to try - run either from 48V direct power to the
circular connector on the camera or use a single-port PoE injector that you
received according to the invoice.

Re: [Elphel-support] Placing an order for NC393 - F - CS

[Olga Filippova]

Hello Roman,
Thank you for your interest in Elphel NC393 cameras.
Please let us know a little more about your application, so we can help you
better. For example the NC393 camera system board (
https://wiki.elphel.com/wiki/10393) has 4 sensor ports and supports 4
sensors. Maybe you will need just 5 cameras with 4 sensors each?
The prices can be found at
https://www3.elphel.com/importwiki?title=Price_list
and you can see there are different configurations possible.
Let us know what other questions you may have,
Best Regards,

Re: [Elphel-support] Support / slit camera for horse race

[Olga Filippova]

Hello Walter,

Elphel camera NC353L (older model) is being used for photofinish purposes
by at least two of our customers. We also have a blog post from another
user who did photofinish with Elphel camera a few years ago:
https://blog.elphel.com/2010/11/elphel-as-a-line-scan-camera-for-river-panoramas/
https://blog.elphel.com/2018/01/photo-finish/
You can also read on elphel wiki about photo finish applications:
https://wiki.elphel.com/index.php?title=Special%3ASearch=Search=500=photofinish

If you go on elphel.com, there are multiple tabs, and you can type
"photofinish" in the combined search - there is information on the blog,
wiki, and support list about it.

All Elphel software is Free and Open Source and distributed and protected
by GNU GPL v.3 license. Hardware is under CERN Open Hardware license. You
are welcome to use the existing code and write your own application
specific software. If you plan to distribute your software it has to be GNU
GPL.

We also have the new model NC393, and it is possible to use it as a line
scan camera, but we have not yet had any customers who have done it.

Re: [Elphel-support] multiple cameras synchronization

[Olga Filippova]

Hello Dor,
Thank you for your interest in the Elphel NC393 camera.
Answering your questions:
1. The 4 sensors are supported by one system board and are precisely
synchronized.
2. It is not possible to replace the image sensors - we use 5MPix image
sensors. You can design your own system board to use other sensors, but
that would require also writing drivers for the system board to support
these sensors.
3.The prices can be found on our Price List:
https://www3.elphel.com/importwiki?title=Price_list
4. We do not have the software to build panoramas from all 4 cameras.
5. The link to SDK is from this page:
https://www3.elphel.com/model_393_cameras, and here is a direct link:
https://wiki.elphel.com/index.php?title=10393#SDK

Multiple cameras can be synchronized together. The cameras are distributed
under Free Software and Open Hardware and it is possible to access al the
source code, so you can add software that you need for your particular
application.

Hope this helps,

Best Regards,
Olga S Filippova,

Re: [Elphel-support] Eyesis4Pi-26-393

[Olga Filippova]

Dear Lorenzo,
Thank you for your interest in Elphel cameras and I am sorry we did not
reply sooner.
I am copying this to our partner in Europe, Mr. Alexandre Poltorak, who can
help you with questions regarding Eyesis4Pi camera.
We are happy to answer technical questions, but please refer to Mr.Poltorak
regarding camera purchase.
It is possible to record images directly to a PC. Assembling custom 180
degree camera will require custom design modifications and re-calibration
of the camera. It might be possible not to include the IMU, but again it
will require re-calibration. The GPS, is needed for absolute time stamping
of the mages.
Please feel free to ask any other questions - we will try to help.

Re: [Elphel-support] 答复: information about NC353 camera

[Olga Filippova]

Dear Tao Zhang,

All Elphel software is Free and Open Source, distributed under GNU/GPL v.3
license. It is all available on Git repository from our main web page:
https://www.elphel.com/ - look in the tab "Code", and you can also search
all Elphel sites.
There are no  specific code for stereo applications, the camera produces
synchronized, time stamped, geo-tagged images. Our clients may have
developed application specific code, - you can search in the Support List
for the developments done by others. There are also 3rd party free software
projects like OpenCV you might find useful for your application. Search
OpenCV in Elphel combined search (all sites)
https://wiki.elphel.com/index.php?title=Special%3ASearch=Search=500=openCV

We have developed software for the calibrated camera system, that uses
special sensor-lens modules, corrected for optical aberrations and
distortions, and thermally compensated, which allows the multi-sensor
camera to accurately measure distances to objects in the photograph, - the
links to software  and demos are in the blog article:
https://blog.elphel.com/2017/09/long-range-multi-view-stereo-camera-with-4-sensors/
and more articles about Elphel calibration process and products:
https://blog.elphel.com/category/calibration/

I will send you the updated quote in a separate e-mail.

Re: [Elphel-support] information about NC353 camera

[Olga Filippova]

Dear Tao Zhang,

The NC393-Stereo camera can be assembled similar to this camera:
https://www3.elphel.com/sites/default/files/images/mnc393-printed-inline.jpeg
but with 2 lenses. You can also specify the base distance between 2 lenses,
and we will try to accommodate it.
The 2 sensors are precisely synchronized, so you will get synchronized
stereo images from 2 sensors, and 2 stereo cameras also are synchronized
with the 10389 extension board. The 10389 also provides SATA and USB
interfaces and allows to connect the GPS. You might also consider using the
103696 Serial GPS Adapter Board with Synchro Input:
https://wiki.elphel.com/wiki/103696 that allows perfect synchronization of
the GPS with images.

I have listed all the major parts needed to assemble one NC393-Stereo
camera, itemized with price, please find another email with the quote
attached.

You can see the camera and take it apart in 3D model (we do not have the
Stereo model, but the main electronics parts are the same for all cameras)
here : https://wiki.elphel.com/index.php?title=Elphel_camera_assemblies  -
(click on the web/3D icon under each camera picture).

I wonder, if you would not benefit from the single camera with 4 lenses
instead of 2 Stereo cameras - please take a look at H-camera:
https://www3.elphel.com/sites/default/files/images/mnc393-printed-H.jpeg
These 4 lenses are synchronized and it is less expensive because 1 system
board can support all 4 lenses.

Camera operation manual is on our wiki page:

SDK:

Re: [Elphel-support] Ordering stereo camera

[Olga Filippova]

Dear Elham,

I will send you another quote in the next e-mail.
We will include SD-card and micro USB cable free of charge as these items
are part of the camera. SD-card is needed for initial booting the camera
and for recovery. Camera lenses are sold separately from the camera,
because we do not manufacture lenses, we have to purchase them, so we can
not provide discount, but please note that we sell these lenses at the cost
price.
We can make the camera base at 22cm and 44cm, the base is not variable,
unless you disassemble camera and modify the base.

Best Regards,

Olga

Re: [Elphel-support] Ordering stereo camera

[Olga Filippova]

Dear Elham,

we can send you the Inline camera but the waterproof case is not going to
be ready. It will take several weeks to machine some parts that can not be
3D-printed, after the design is finished.
We can sponsor this project provided that your software is free and open
source and all documentation is available on Github or similar repository.
It would be also nice if you can write an article on Elphel blog about your
project, like other sponsored clients did:
http://blog.elphel.com/category/success-story/

Re: [Elphel-support] Ordering stereo camera

[Olga Filippova]

Dear Elham,

can you please explain the technical reasons for ordering inline camera? It
looks like you plan to use Inline camera as 2 stereo cameras with 2
different bases. This is fine, but it has been done before, while the
H-camera presents interesting research opportunities.

Practically speaking we offer 4.5mm lenses (custom adjustment has been made
to fit this lens to the camera, using 3 different adapter rings, as can be
seen here:
http://www3.elphel.com/importwiki?title=File:N125B04530W_adapter.jpeg) But
we do not offer any 9 mm lenses - we have not tested any of 9mm lenses and
we don't have these in stock, however you are welcome to purchase such
lenses separately and install them on the camera.

I am researching the exporting regulations to Iran. I think we can ship our
camera products to Iran, but I need to receive answers from the exporting
agency, to make sure.

We offer standard 48V power supply that converts AC power from wall outlet
to 48V DC power. The camera uses 3.3V, but the power supply has to be
minimum 12V, or 18V better, especially for camera with 4 image sensors. You
can power the camera from the boat power supply. For development it is nice
to have a wall adapter, like the 48 V AC-DC converter we offer (or you can
use the one you already have or can purchase locally).

Best Regards,

[Elphel-support] Fwd: Ordering stereo camera

Dear Elham,
I have replied yesterday to you, although I forgot to reply via support

Dear Elham,
The waterproof case for the camera NC353-369-STEREO was designed by one of
our clients - an company in Australia, Mercurien. We were offering it on
our site, but it has to be purchased separately, from them.
Nc353-369-Stereo camera is our older model, which can be sold at it regular
price, and I can send you a quote.
We are interested in sponsoring new camera models to have more Free
Software developed for the new models.
We would still recommend the H-camera - Andrey had explained it's benefits
for your application, and we can offer it at 50% off (which is the cost of
manufacturing). We also are working on the waterproof case for H-camera.

Please let me know how would you like to proceed.

Re: [Elphel-support] Ordering stereo camera

[Olga Filippova]

Hello Elham,
all camera models made with 3D-printed parts are just examples of the
possible configurations. We offer our clients the freedom to modify camera
configuration based on their needs and application. The camera with 4
sensors can be arranged in any way you  want to design it. It is also
possible to purchase the example Inline camera. It has a fixed baseline of
250mm, but it can be larger, limited only by the cable length. The longest
cable we offer is 450 mm, so the largest baseline could be something like
700mm.
Please note that we are working on the waterproof camera body for the
H-camera, not the Inline camera.

The 4 image sensors are synchronized and are taking images simultaneously.

The lens we offer is Evetar, N125B04530WR1 with EFL=4.5mm, the focus is
fixed on infinity. http://www3.elphel.com/accessories
You can also choose your own lens (C or CS mount, or M12 mount).

Re: [Elphel-support] Ordering stereo camera

[Olga Filippova]

Hello Elham,
yes it will be possible to order the Inline model stereo camera with 4
sensors.
As Andrey have mentioned, Elphel cameras are Free Software and Open
Hardware and are distributed under GNU GPL license
http://www.gnu.org/licenses/gpl.html and CERN OHL
http://www.ohwr.org/projects/cernohl

 We would like to sponsor your project and follow it on Github repository
(for example), or Sourceforge or Bitbucket with sources available for
download. Here is an example of another project which had used Elphel
cameras for their robots:
https://bitbucket.org/scinirov/scini/src/66a3b41e2763737dfa6ae5aab79a38b86674d702/build/source/?at=master

We have started designing the waterproof camera body, and some parts can be
3D-printed, however some parts we will order to be machined. Finishing the
design, manufacturing parts, assembling and testing will take some time.
Maybe you can make waterproof case faster. We will upload the parts for
waterproof body as Open Hardware once it is ready, and you are welcome to
share your design as well.

Please let me know how would you like to proceed with the order, and if you
will have any other questions.

Best Regards,

Olga

Re: [Elphel-support] Issues with Compact Flash installation

[Olga Filippova]

Dear Riccardo,

You have selected the correct CF card, so the problem is not with the card,
but with either 10353, 10369 or 103691 boards. We can offer to send you all
3 boards for replacement.  It is most likely that only one board is
responsible, but we recommend to assemble the 3 replacement boards
separately and test the CF cards with them. After that you can detect which
one board you need to replace in the camera, and I will give you the
instructions on how to return the other 2 and the replaced board.
Please let us know if you will have any other questions.

Best Regards,

Re: [Elphel-support] 0353-12-01 - Sensor Front end

[Olga Filippova]

Hello Justin,
the Sensor Front End new part is 0353-12-29 and companion part 0353-12-30
for the new sensor board. You can type these numbers in Google and get
straight to our wiki page to see them. The old part was 0353-12-01 and it
is used on the assembly drawing
http://wiki.elphel.com/index.php?title=Elphel_camera_parts_0353#NC353L
which is a little dated now. The price for 0353-12-29 + 0353-12-30 set is
$75 each, so $ 225 + $ 20 for shipping.

Hello Dimitrios,


On Mon, Nov 14, 2011 at 9:56 AM, Dimitrios d...@telemetry.gr wrote:

 Hello Elphel

 I'm looking into purchasing an Elphel camera and have a few technical
 questions:

 1. Do the 10369 adapters (i.e. 103691,103692,103693 etc.) that are
 mentioned in 
 http://wiki.elphel.com/index.**php?title=10369http://wiki.elphel.com/index.php?title=10369come
  as standard or have to be purchased separately? I think they don't
 show up as separate in the price list.

the boards 103691 and 103693 are  part of the NC353L-369 camera, but 103692
http://wiki.elphel.com/index.php?title=103692 is supplied for the
NC353L-369-HDD camera, since it is needed to connect hard drive.

 2. What is the capacity limit with the CF cards that can be used in the
 camera? Can 2x16GB cards or higher be installed?

We can use 16GB as well and possibly 32 GB, however we haven't tested the
32 GB option.

 3. Is there a specification that the CF cards should conform to?

Yes, there are specifications to the CF card, because most of the cards
claim that they support the DMA and Ultra DMA connection, but in fact most
of them don't. And the Axis processor we have inside the camera can only
work with DMA.
It is all well described in an article by Andrey Filippov:
http://www3.elphel.com/linuxdevices/articles/AT5102023409.html
in the section: Connecting Compact Flash cards

So here is the flash card we use:
SanDisk Extreme 3
CompactFlash
30MBs
4GB or 8GB, or 16GB, and may be 32GB



 4. Can the foam in the camera case be cut to suit a specially shaped
 camera? If not, can it be delivered uncut so that it can be cut to shape by
 the purchaser?


The foam is cut to fit NC353L cameras; there is an option to use cubed
foam, your can pluck to fit other shape, as long as it still fits in the
standard case. We aslo have larger cases, usually used for Stereo/3D Elphel
camera.



 Thank you

 Dimitrios

Hello Viatcheslav,

We can send the new 10353 board to you, if you think you can disassemble the
camera and replace the board. In this case please ship us back the 10353
board, so we can test it and find the problem.
The other option would be to ship the camera back to Elphel, and we will
replace the board here.

  Hello Andrey,

 we tested the camera the way you described. Here are the answers.


 What camera is it? Does it have 10359 board? 10369 board? What software is it 
 running ?

 It's the 10353. I tried this with the original software that was on
 the camera, with the software compiled from the sources and also with
 modified sources (both FPGA and MC).


 a) changing the image in front of the camera - you can check it by putting a 
 mirror in front of the camera lens and
 rotating the mirror

 I do not get this?! What should this do? Doesn't have any influence if the 
 camera and the cable are fixed.

 b) shaking the camera itself (i.e. bad contact in the internal flex cable) - 
 you can turn the network cable around and tape it to the camera, so when you 
 move the camera, nothing changes to the network connection

 The distortion appears.

 c) bad contact in the network cable - attach camera firmly to the table and 
 move the network cable

 This is what we think that causes the problem. When messing around
 with the network cable in the jack at some positions the image
 distorts and after moving it again, the image gets distorted in other
 ways, also getting a normal image is possible again.

 d)  it actually happens not because of the movement, but because of the 
 electrostatic discharge when you touch the camera

 Shouldn't the case be electrostatic discharge proof? But without even
 touching the camera (only moving the network cable) the image
 distorts, I tried this with the camera attached on the tripod.

 Viatcheslav

 As for moving the camera as the reason for breaking the image - it can
 be one of the several reasons, you may narrow down the problem by making
 some testing:

 a) changing the image in front of the camera
  -  you can check it by putting a mirror in front of the camera lens and
 rotating the mirror

 b) shaking the camera itself (i.e. bad contact in the internal flex cable)

[Elphel-support] Panoramas From the Backpack

[Olga Filippova]

Hello Grahame,
thank you for the appreciative comments and practical suggestions. Do you
mind posting them on the blog (as a comment to the article) ?
The backpack design can definitely be improved, and other 3D positioning
correction will be done with IMU, once it is ready.

Finishing the IMU is one of the top priorities right now - hardware is
assembled and Andrey is finishing the software for the new IMU/GPS/odometer
logger for the cameras. It is FPGA base; the data from several sources will
be recorded at high rate and transferred to the system memory over DMA
channel to off-load the CPU.

The IMU interface board is designed for the ADIS-16375 we have now, but may
be modified to use with other sensor devices.
GPS interface can process up to 4 NMEA messages (format is run-time
programmable), the data is compressed to fit into 56 byte message (most
numeric filed use 4bits/digit) to the total of 64 bytes (including precise
timestamp)
third channel accepts generic pulses (i.e. odometer) and is also logged with
timestamp
fourth channel logs sync pulses in multi-camera systems (as in Eyesis -
http://blog.elphel.com/2011/02/eyesis-4pi/ )

We are really interested in creating software to support this data from the
high-res panoramic camera, and hope to find somebody to cooperate with to do
that. Additionally we now have very precise distortion calibration of the
camera/lens software, so it may be used to accurately match the pixel
coordinates to the angles in space.

Thanks again for your comments,

Best Regards,

 Hi Guys!

 Excellent photos and I am sure you all enjoyed the experience
 (especially of lugging a man-mounted-ray-gun around to the amazement of
 other hikers).

 Looking at how the Elphel-Eyesis unit is mounted to the back pack, and
 the angle of incline relative to the ground and the hiker's back - I
 wonder would it not be advantages to have the following added to the
 overall project (I not sure this may have been mention before or not -
 Apologies if it has).

 1 S/W to handle the low level (possibly medium impact) vibration(s) and
 varying degree of perpendicular given; the walking steps of a heavy
 backpack unit; probably a sore and unsteady transport (i.e.: Further s/w
 evaluation as was carried out on the truck / Sports Utility vehicle
 movement and picture quality) and variations over different
 transporters.

 2 As the distance travelled by a human is vastly smaller over time than
 a vehicle, a mechanism to reduce the frequency of shots taken (That is:
 the multiple number of shots containing 50% the same scene.) This way,
 the quantity of cached images will be less, but as they carry more that
 50% of sequential differentiated images, s/w be able to resolve any
 mismatch issues with the auto panorama s/w.

 3 Be nice to have the hikers health (breathing, heart rate, etc)
 recorded so that one could give a order of merit / recognition of the
 efforts undertaken in capturing such panoramic images :)

 Grahame.
