Missed Camera Trigger

Just bought Map Pilot app, carried one small mission about 60 Acres. It has 4 Flight Lines, Triggering is not consistent(Distance varies) , I am really upset with this behavior.

I am a experienced photogrammetrist and done several UAV precision
mapping projects with DJI S900.

Please let me know how can I fix this.

What mobile device are you using? DJI added some CPU intensive logging functions that are making it so some devices are falling behind. That sounds like what you are experiencing.

Make sure you are using the highest quality SD cards available and that they aren't more than 50% full since that will affect the write speed.

Also, to minimize CPU usage, disable the Image Footprint display (green box) in the settings. It requires a lot of processing power to look up the terrain corners quickly.

Hopefully that helps. We have a new version coming out in a couple of days that has an updated version of the DJI SDK so hopefully they will have cleaned up their logging a bit.

I had a similar issue 2 days ago.

Im my case, its an IPAD A1600, with IOS 10.1.1 (14B100).

Your iPad has an A7 processor which used to be enough to keep up with everything. We are finding that it ends up being pretty slow now with anything less than an A8.

We've updated to v2.3.0 this morning and tried to use the new "connectionless" mode using distance based triggering instead of the previous interval (or time) based triggering. Unfortunately we couldn't get the camera to trigger at all. We tried on an Inspire 1 and a Matrice M100 with both an X5 (with two different lenses) and X3 camera. Each airframe and camera is using the latest DJI firmware available. The "active connect" mode worked perfectly.

I am a professional and experienced photogrammetrist and have a thorough understanding of your application. Is there something that I have missed?

Matt: Your issue is likely different than this but may be similar to Fabio's problem.

You may have the SD card setting on a fast setting. The X5 is pretty slow to write out images so select the slowest SD card write speed in the settings menu (3 seconds). The distance based triggering is a brand new feature for DJI so we are still trying to find out the issues with it.

Slowing down the SD write speed will slow down the aircraft a bit and give the camera more time to write out the images.

If there problem persists, please send us a log file of the issue happening.
