Svo2 imu frequency very low with CAMERA MOTION SENSORS NOT DETECTED errors

Software
1

I record the data using svo2 file. When i run it live i have a varying imu frequency between 150-200 hz, but when i run it with the svo2 file with svo_real_time_mode = true then most of the imu measurements gives CAMERA MOTION SENSORS NOT DETECTED, and my frequency is only around 30 hz. Should i read the measurements differently when reading from a svo2 file? i use ZED SDK 5.1.2

Hi @Jacob
Please share the SVO for testing.

Please also try to install the latest ZED SDK v5.2 to confirm that the problem is still present in the new version of the SDK.

I cant upload it to here because of the file size, how would you prefer i send it to you?

You can use the file sharing service that you prefer.

Here is a weTransfer link, let me know if you cant download it.

Hi @Jacob
Is it an SVO recorded with a virtual stereo camera?
If that’s the case, please share the calibration file too.

Please do not omit this kind of useful information when reporting a problem

Sorry about that. It is a virtual stereo camera with two zed x one GS. Here is the calibration file

Hi @Jacob
I tested the SVO with the ZED ROS2 Wrapper and I can retrieve IMU information at an average rate of 300 Hz.
I tested enabling and disabling svo_real_time_mode and the behavior is the same.

I cannot see this error.

Please try to upgrade to ZED SDK v5.2 and eventually share the code that you are using to retrieve the IMU samples.
