[Elphel-support] Ordering stereo camera

Mon Aug 22 06:39:36 PDT 2016

Hello Olga,I apologize for delay. I must consult with my supervisor. According to our calculations, baseline 22 cm and focal lens 4.5 mm is suitable for inner cameras and for outer cameras we need larger focal length and we don't know exactly what kinds of lenses do you have for this purpose? because we want to use inner cameras in 4-20 meters, and outer camera in 20-100 meters(on your opinion what kind of lenses is suitable for 20-100 meters?).
 My supervisor emphasis on waterproofing, he said that H-model or Inline model that is waterproofing is appropriate for ours. Now, on your opinion, when is H-model waterproof enclosure ready?my friend lives in Georgia, can you send camera for her? how long does it take to get to her?

I looking forward hearing from you.
Best Regards Elham

 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).

Best Regards,

Hello Olga,Thank you for your guidance.I have a few questions: In this Model (Inline model) is the baseline  variable?
In this system, are two cameras (or all of them) used at the same time?
Does the lens have focus?
Kind Regards
Elham

 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/ 66a3b41e2763737dfa6ae5aab79a38 b86674d702/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

 Hello Elham,

As I wrote you earlier - we do not have any waterproof camera, the only weatherproof (they withstand rain but can not go underwater) we manufacture is Eyesis4pi (it is more expensive device).

Our users were able to use Elphel cameras deep under water (see project SCINI -https://www.google.com/ search?q=scini ), but it is their design, not ours. We provide open hardware cameras so you can download all our design files and develop the additions required for your particular application, and if your design is open too (so others can use your CAD files, software under acceptable FLOSS license) we may provide discounts (as I wrote earlier).

We may develop some weather-proof H-camera ourselves, especially if there will be customers eager to pay for such product. But I can not promise to put all our work aside do develop such new hardware - we can do it only in our spare time (which currently we do not have). Your team has at least twice more members than we have at Elphel, so you can develop mechanical parts yourself (as other users do) faster (and less expensive too) - we can definitely help you with consultations and tell if we think your design will work, what potential problems it may have.

Andrey

Hello Andrey,The longest of your cable is very good.because this camera will be used in outdoor condition, it is very important that it is waterproof.  can you design  H-camera with environmental protection?How will send us? and how many days does it take?
