hi. How can i draw the trajectory of my flight in 3d space without using GPS and may be using the Dataflash logs with imu and yaw pitch roll values. something like https://www.youtube.com/watch?v=p6JYP5WzFY4
yes, it is possible. convert the Dataflash logs into matlab and do a matlab sript to load the files and plot them.
thanku. but i was really looking for some more specific instructions. If there is some library or something that i can use, give it my data of imu sensors and that library may be plot the trajectory for me?
A simple google search for “mission planner dataflash log matlab” gave:
Hello everyone!
Almost two years ago, @hunt0r and I needed to parse some ArduPlane logs. We are both on our track to get a PhD in UAV control systems and Matlab is a very common tool in our trade.
Sadly, at the time the only tool able to convert from DataFlash logs (.bin) to a format readable by Matlab was Mission Planner and it didn’t serve our needs well enough. It would work only on Windows, take a very long time to convert and would ignore all text fields.
So, we decided to create our o…

Hello everyone,
I have begun working on a DataFlash diagnostic toolbox for fixed-wing aircraft, the mavlink-inspector .

Log analysis has always been interesting to me. Being able to watch someone’s flight at the ease of your desk and be able to resolve the causes of a crash or point out tuning deficiencies sounds exciting and borderline magical. Leveraging the value of stored information to identify the weak points of a real-world system is invaluable.
