Low imu frequency (190Hz, unstable) of ZED X1 GS with Jetson NX16Gb on ZED mini carrierboard.

Good afternoon,

I have 2 (sn300473976 and sn309573082) x1 gs cameras (stereo configuration) both have the same problem on all 3 topics:

  • Accelerometer
  • Gyroscope
  • Orientation

The data comes at a lower frequency than reported in the webshop and is not stable at that lower value. Its important to mention that I have first encountered this issue in my ros2 setup and discovered that it is also present in ZED_Sensor_viewer, so I don’t know how to proceed on my own. Any ideas how to debug this issue?

I have the recorded .csv file at hand, however I cannot upload as new accounts cannot upload documents on this forum :(.

Have a nice day. Kuba

Hi @kubaplonka
Welcome to the Stereolabs community.

What is the expected value?

Thank you for your reply. 400Hz/200Hz as reported in the datasheet of this product: https://www.stereolabs.com/en-nl/store/products/zed-x-one-gs . For my purposes all I need is a stable value of at least 200Hz, however 400Hz would be much appreciated!

The correct ODR value for the Gyroscope and the Accelerometer of the ZED X One cameras is 200 Hz. The product page has been fixed.

What NVIDIA Jetson model are you using with your cameras?

Well that is quite unexpected! I am using NVIDIA Jetson orin nx 16gb with your ZED mini carrierboard. Those 190Hz (Instead of promised 200Hz) are too unstable (175-195, most commonly ~191 Hz), happening on both of my cameras. If I could provide you with more useful information about my setup or run any tests on my side, let me know!

What ZED SDK version and ZED X Driver version are you using?
I can get stable 195/200 Hz with the latest ZED SDK v5.0.7 and driver v1.3.1
