Hello, I'm working on synchronization between IMU and event camera(EVK4). I use hardware trigger to synchronize as documentation says. However, it is hard to evaluate the synchronization quality. A naive way is the compare the data between IMU acceleration and events number when a sudden vibration happens. In my test, I find that although the timestamp between IMU and event camera is stable, IMU data does not always go up quicker than event camera, and it seems like a random distribution(sometimes quicker and sometimes slower). The figure is attached as follow. I wonder if it is a right way to evaluate synchronization and if my synchronization is fine and hope you can help me.
