Hi, i’m a new user and I’m trying to perform my missions using a fixed wing as a aeromapper.
I’m confused about the “DO_DIGICAM_CONTROL” command in mission planner V1.3.33 because when i plan a mission by “Survey (grid)” method, the lines “do_digicam_control” appears with the first and the sixt field =1, and the fifth field (shutter cmd)=0.
With this command line the shutter does not work.
Instead if I manually put 1 in the fifth field of all mission “Do_Digicam_control” rows, and “0” in the first and sixt Field, then the shutter work perfectly. I doesn’t work with all fields ="0"
But if I insert a new row by click the button “Add below” and chose the command “Do_digicam_control”, then the command automatically appears with the field “Shutter cmd” = 1 and other fields =0
This behavior appears strange and it forces me to manually correct all rows “Do_digital_control”, but i Think this isn’t the right way to use this command.
Is there any solution to this problem?
to see the details of this command. Param 5 is the command to trigger the shutter. Note that this command will only trigger the camera one time.
If you are doing a survey mission, you are probably better off using the do_set_cam_trigg_dist command. It will trigger the camera every x meters. You only need to insert this at the start of your mission. Insert another one at the end of the mission with the distance set to 0 to turn off camera triggering. Mission planner should at least insert the first one for you. See plane.ardupilot.com/wiki/common- … trigg_dist
Hi James, thank you for your replay.
I know the metod you described, but i need to use Do_Digicam_control because in case of wind the flight with only two waypoint at start and end of each lane of one tipical mapping mission is not enough accurate. Then i hope it will be solved the question as soon as possible.
Now i manually correct the fifth parameter in each row of the mission and the arduplane work perfectly, but if i perfprm a mission with many shots, this is too complex to do.
Yesterday i tried to install an old firmaware (I changed the actual arduplane 3.4 with the firmware 3.22) and I surprise to discover then with this firmware version the command “Do_Digicam_Control” work fine also if i Put “1” the first and the Sixth parameter, or also evenif i put =0 all parameters.
Is there anyone wich can explain this strange behavior and suggest how to use the version 3.4 with “do_digicam_control” without editing the fifth parameter and put it = 1 in a mission planned by SURVEY_GRID function?
Thank You
Fabrizio
Dear Fabrizio! Thanks for the investigation. Hopefully this will solve our problem as well: do digicam control works fine with arduplane 3.3 but when upgrading to 3.5 it suddenly stops taking pictures. Even though trigger camera now works perfectly from mission planner! I do not know if this problem had been addressed by mission planner software updates or not?
