"Junk" data in Gyroscope mode

Hi,

When I used the ZED Sensor Viewer in Gyroscope mode, I got the following data. Why is there such “junk” data in the x-axis?

Hi @vancao2609
Welcome to the StereoLabs community.

I noticed that the data on the Z-axis is also not coherent.

Please run ZED Diagnostic and share the content of the JSON file that it generates.

Hi,
This is the result JSON file after I ran ZED Diagnostic.

This is a screenshot. You must click the “SAVE” button when the diagnostic process is completed and send me the file it generates.

This is a ZED Mini camera. The calibration of the IMU is probably no longer valid.

Please put the camera on a planar surface (the floor is good) and run this command:
ZED_Calibration --cimu
if this does not fix the problem, please run this command:
ZED_Calibration --calib_dynamic

What are there command: ZED_Calibration --cimu and ZED_Calibration --calib_dynamic?

Hi Nguyen,

What are there command: ZED_Calibration --cimu and ZED_Calibration --calib_dynamic?

They are text commands to be executed from the shell.
