Extended from this topic, I'd like to ask if you use the implementation for calibration using `kalibr` (https://github.com/ethz-asl/kalibr). If so, does the calibration result achieve good accuracy?

@themarpe , @alex-luxonis First off, my hearty gratitude for your comprehensive clarification of timestamping method that is adopted by you, which is a brilliant way. Then I'd like to double...

@themarpe , @alex-luxonis There's still one question about exposure time. Given your current timestamping method and auto exposure by default, I'd like to try using fixed exposure in my software...

I tried stereo setup without IMU information by doing the followings: 1. Build a new launch file based on the launch file "euroc_stereo_frontend_imu.launch", with launching commands related with IMU commented/removed,...

To be continued from last comment - After debugging, I found that problem can be traced back to the threshold controlling the validation on the rotation matrix, which is defined...

> To be continued from last comment - By further inspecting the code, the above problem should be attributed to the synchronization problem, i.e., the two image channels were not...

> Any updates on that? I also intend to use SVO on stereo without IMU I have tried that setup yet, as I turned to vio. I may try again...

I then further check your code in terms of IMU propagation, you cancel the propagation the covariance, as shown in invoking the function https://github.com/uzh-rpg/rpg_svo_pro_open/blob/ca371f304637e7fb355cf4624d0a02da4e3da220/svo_ceres_backend/src/estimator.cpp#L201. So, it seems that you don't...
