ROS compatible tool to generate Allan Deviation plots
hi! i got calibration papers:   this is cheap mpu-650 (GY-521). how to understand is it good or not ? what "stars", "circles", "triangles" mean ?
thanks for sharing your work. when I try to run rosrun allan_variance_ros cookbag.py --input workspace/imu_calibration.bag --output workspace/cooked_rosbag.bag I get this error :Failed to load Python extension for LZ4 support. LZ4...

I am trying to calculate accel and gyro noise and random walk for Intel realsense. I quickly generated imu csv in the format specified [here](https://github.com/ethz-asl/kalibr/wiki/bag-format) using custom CPP script for...
To be able to use the bias instability model, the correlation time is required, which is currently being recorded in the code but not logged. The main change in this...
I was referring to calculation of gyro and accel white noise and random walk using the video [Visual-Inertial Sensor Calibration - A Complete Tutorial and Discussion](https://www.youtube.com/watch?v=BtzmsuJemgI) for my Intel Realsense....
Today i tried to install the allan_variance_ros and i face a lot os issues. **1st error** `User geo@geo:~/allan_ws$ rosrun allan_variance_ros cookbag.py --input /home/geo/allan_ws/original.bag --output /home/geo/allan_ws/cooked.bag Traceback (most recent call last):...
In analysis.py, from lines 97-107, you calculate white_noise_break_point and use it as an index to limit the interval where the white noise fit is calculated on. You also calculate random_rate_breakpoint...
Hello, For calibrating and I guess in general in VI state estimation. When I have IMU measurements which are in the "proper acceleration" (https://en.wikipedia.org/wiki/Accelerometer) frame, do I need to invert...
Hi, I run the data [Realsense D435i IMU](https://drive.google.com/file/d/1ovI2NvYR52Axt-KuRs5HjVk7-57ky72H/view?usp=sharing)，the result is not as same as yours,   below is my configure,is any problem with it imu_topic: "/camera/imu" imu_rate: 500 measure_rate:...
