May I ask that is there any better way to calibrate the magnetometer?
I have tried to do the figure 8 calibration, but the result can only depends on your luck.
is it the problem of my skill or it i…

Kris,
in you code around line 625, do you deal with the singularity at +-90% pitch as described in your reference here [http://en.wikipedia.org/wiki/Conversion_between_quaternions_and_Euler_angles](u…

Hi Kris,
Thank you a lot for the source code!
I implemented Madgwick source code with LSM9DS0 and the data that I get are really good but I have a problem with aligning the sensor orientation with…

Hello Mr. Kris,
First of all let me thank you for your work regarding IMUs and how to get readings from them.
Right now I have an arduino sketch that takes the readings from a single sensor and…

Using the logic below to create a quaternion array in the _compute_all method overwrites Q[t-1] with the value that should be at Q[t].
```
for t in range(1, num_samples):
Q[t] = self.up…

Hi everyone. First of all, thank you kriswiner for your effort and great work. I'm using an MPU9250 with an STM32F103 (blue pill) which has a 72MHz clock speed. After calibrating the mag I recorded an…

Hi Kris
Sorry to bother you again. I'm having some funny stuff happening. I have my system calibrated and outputting yaw pitch roll. The funny thing is that pitch and yaw work perfectly but roll is…

Hi,
i have both t265 and d435i, and i want to use both for increase accuracy in rtabmap. Is that possible? Will i get better result using both sensors?
thanks

Hi
I have recorded a rosbag in my rpi to do compile rtabmap on my pc. However I am encoutering issues when i launch rtabmap node.
I used the IMU filter suggested. This issue is not present in my rpi…

Hi Kris,
Thanks for sharing your codding. I'm trying to implement AHRS using MPU9250 and stm32 MCU. I use DMA to read data at freq=1.6Khz (except magnetometer), ant it works perfect. The filter update…
