May 4, 2020 · Step 17: This completes the DJI Mavic Mini Calibration with the message stating "IMU calibration complete. Please restart your aircraft". Step 18: Click OK and restart the Mini. What if DJI Mavic Mini IMU calibration failed? Check that the surface where you are doing the calibration is totally flat. Try the Mini IMU calibration a second time.

Feb 19, 2017 · Calibrating the IMU on a drone that hasnt crashed is like buying a brand new tesla and replacing the batteries just incase they are faulty. Perhaps read up a bit on the IMU what it does and how it works. Then u might understand why a recalibration is about as usefull as putting makeup on a pig.

Nov 12, 2017 · BTW, use the IMU Module from the Mavic 2 (the module is the same, the mount is different) that I bought from Amazon for $29.00. Amazon.com: DJI Mavic 2 Service Part - IMU Module(Pro/Zoom) - Original OEM: Toys & Games

基于imu的定位(也就是我们通常称为的惯性导航)本质上属于航位推算定位，定位解算是基于运动积分的，之前定位结果中的定位误差会累积到当前定位结果中，同时由于imu本身的零偏，最终表现就是定位误差会随时间累积。

既然提到的是imu，那就是捷联惯导，一般我们会将imu或者惯导模块固连在载体上。符合右手系的载体系定义，一般常见的有前右下或者右前上等。在仿真算法中，简化处理就是将imu的输出考虑在载体系了。实际运用当然需要考虑imu坐标系和载体系的安装关系。

Nov 29, 2019 · Hi guys, I have an issue. I hit a plant when trying to land (less than 1 meter high) The drone fell to the floor and the motors stopped. The MM is now telling me to calibrate the IMU and when I press the calibrate button it takes me to the calibration screen but the problem is when I …

Oct 19, 2016 · how long should it take for IMU calibration. Im following the instructions and my screen has been sitting on 2/5 for almost 15 minutes. It has a clear warning not to power down the aircraft -- but I'm wondering if something is screwed up.

Jul 8, 2017 · The first time I tried to initialize the IMU I did it wrong. The last few times I did it exactly as your video later confirmed. Although I go through all the steps and the "success" screen shows, I still get an IMU warning as well as the compass calibration warning. When I try to calibrate the compass I don't get past the first rotation step.

IMU预积分模块中代码涉及到多次坐标系转换。主要是要明白IMU积分的原理和LIOSAM中坐标系的转换关系。关于坐标系有几个注意要点： 1. 所有IMU原始数据都会先旋转到与雷达的坐标系朝向一致后再进行处理. 在imuHandler中每收到一个IMU数据就先旋转再存放。code

Oct 18, 2016 · The secret to doing an IMU calibration is: make sure the bird is not warm before performing an IMU calibration so if you have had it powered on to change settings or just to play with it turn it off and leave it off until it's cooled down -- …
