RPI wired network

setcamerav2

HI,

 

I would like to create a wired network of several (6) RPi with cameraboard v2. I would like to use one (more) RPI to send all the other RPIs the same signal (i.e. to shoot a still picture at the same time).

I am a complete newbie in RPi and networks.

Anyone could give any instructions to do that and or any hints on where to find?

Thank you.

 

Giuseppe

    For your first raspberry pi, I would recommend a fullblown RPI3. You could put that one as the master later on if you can't afford to keep the first one on your desk.

     

    If you photograph DOWN too, then you usually have whatever the stuff is standing on (the tripod) in view too. Unless of course you put the stuff under a drone or balloon. Because the ground under the picture is not that interesting, I was assuming you would not need to photograph it.

     

    You can practice stitching by going out and taking pictures with anything that can take a picture. Like your smartphone.

     

    If the WIFI turns out not to be reliable enough, you can always still use a GPIO to trigger all the slaves.

    Thank you very much.

     

    i will buy a RPI3 with cameraboard v2 and practice and figure out most of the things I need 8included GPIO which I had never considered)

     

    I do not need to photograph the ground with the tripod: that would add many problems and it is not interesting.

    But I would need (not always but in many scenes) to photograpph the ceiling or at least to have a vertical field of view of  about 100 ° or more.

    Using the standard lens that means I need two camera in portrait mode (they have 62° FOV which I could overlap 20° and obtain a 100° Fov when stitched, not sure it is enaugh) x 10 (to cover 480 degrees less the overlapping areas, not sure it is enaugh). At least 20 cameras. Too many to manage.

     

    I have found this one: https://www.bluerobotics.com/store/electronics/cam-rpi-wide-r1/ which has a mount that, additionally, allows to change the lens with other M12 lens, but that will be expensive and nothing I know about quality.

    I will first get to know a bit about RPI and the cameraboard and then I will decide...
