Non-Canon Camera Trigger Based on Distance

Posted by opiq on January 11, 2015 at 7:48pm

Dear All,

I am developing UAV for Mapping. I use Canon Camera (SX260HS)+CHDK to trigger the camera based on time interval (intervalometer script) and based on distance (E38 script), both was working well.

Now, I want to use another brand of camera (i.e., Sony, Nikon, Canon without CHDK..etc) but I still have no idea how to trigger it. I have read there are part/component who could trigger with infrared, but I put it as a last option.

I want to modify camera connection by cable to PixHawk and setup the camera trigger based on distance in Mission Planner. If somebody already did it and success, please share the wiring diagram..

Thanks in advance...

Hi Just look at my post here ..it is very easy to make you own cable for canon or sony

  Confirmed, I use Sony RX100 II and Gentles cable on Pixhawk : work great

    From what i understand, gentles cable use IR to trigger sony cameras right?
    
    There are lots of option for IR trigger (eg: stratosnapper), but it has significant delay that make camera from sony nex 5 series couldn't be triggered faster than 4 s interval.
    
    I think what opiq looking for is trigger other than IR method. Using servo to trigger the shutter might be an option as the camera speed limit will be more than 10fps on manual focus

      I ordered few days ago one RX100II and this mount with servo trigger. I will be able to test them maybe in 1-2 weeks, depending on the weather.

        I just received the information, that I will get the mount with the multiport shutter, not with the servo trigger. Much better !

      Gentles uses usb. There is mo IR on Sony RX100 2.
      
      I usually shot at 2-3 seconds interval, flying at 5 m/s with 80% overlap.

        I can fire the Sony NEX-7 at about .7 secs using the Hobbyking IR emitter. For reliability we have modded the shutter button to fire by wire.

        That's nice, can you share the mod? I've been looking of how to trigger nex5 using usb.
        
        From the sensor size perspective, nex series is better than rxIII, have you ever compare the image quality between those 2 camera?
        
        Thanks
