I just pushed the current work in progress to the beta branch, which is available in QGroundControl. We’re currently looking mostly for general regression testing. Main improvements / changes: EKF2 estimator added (instructions to follow) LPE estimator added (instructions to follow) Snapdragon Fl…

@Andreas_Hoffmann I have now fixed the reporting in QGroundControl to use the very same algorithm as onboard and I tested them to match exactly for my T14SG. https://github.com/mavlink/qgroundcontrol/pull/3383 You would need to build QGC yourself or download the latest daily build tomorrow. Let me …

@dogmaphobic Heres the difference on a phantom 3 which is much better results since DJI knows when there cameras trigger. [image]

Here the error is virtually constant, as I would expect from a digital system.

@dogmaphobic That was using APM flying about 16 m/s with a seagull trigger cable and sony wx500. This is the issue we get with these PWM trigger systems on APM and the we eliminate it using the camera feedback system. When mapping we use auto exposure mode on bright days and shutter priority on c…

Here is a cannon S110 with the camera feedback. [image]

[image] Justin_Cooper: auto exposure mode on bright days and shutter priority on cloudy days My guess is that if you use manual focus and manual exposure, you would have zero errors and no need for a feedback system. The variance in error is caused by the camera focusing and computing exposur…

There have been plenty of studies on this topic and the results are always the same. If your not shooting in one of these two modes your results generally turn out visually very bad when compared. We always want focus set to infinity when mapping. That’s why APM had such a big push for the feedback…

For all non-camera people: I’m not aware of big open issues or significant missing features for the 1.3.0 release. If you think something is still wrong, please raise it. Otherwise please help us test as much as possible and share your experience and log files.

I did some flying yesterday which ended in a Fly Away I had to terminate using the Kill-Switch. No major damage to the copter. I assume this was caused due to improper mounting/calibration of the Flight Controller combined with a loss of GPS Signal Quality. I’ll maybe have the chance to test again t…

I’m currently at your log file, thanks! If you are only using the Pixracer mag you might not be able to get decent performance. The interferences in the center of the frame are typically significant and you want the GPS including a mag to be on a mast for good performance. [image] Andreas_Hoffm…
