Inaccurate pose estimation

[KunruiHuang]

Hello,Varvrar, thank you for your great work. But now I have a problem. I run vins-mono test with the data collected by ios-logger, and the trajectory diverges seriously. In contrast, mars-logger(https://github.com/OSUPCVLab/marslogger_ios/tree/56bfe7e78a5f7ea5ad10f97c4fe0d7bd032b0ede), another similar data collection software, runs well. Do others have similar problems? We look forward to answering them. Thank you
