Options to turn off backend
@liuhaomin @wangjio
-
I believe the global ba is on by default. Is there an option to run VIO only?
-
If I focus on the speed of the VIO (the estimation part, not including image processing), which function should I time to get a good evaluation?
Thank you!

If you want to close GBA: [back-end only mode] Set 'debug_gba' to '-1' in config file, and uncomment https://github.com/baidu/ICE-BA/blob/b004bb5afc0d554d49742aae8503d231213f7e6d/Backend/IBA/IBA_config.h#L42 to define Marco 'CFG_DEBUG'. Then GBA will be closed. [run ice-ba] Change https://github.com/baidu/ICE-BA/blob/b004bb5afc0d554d49742aae8503d231213f7e6d/App/EuRoC_test.cpp#L452 to 0x0000FF00, and uncomment https://github.com/baidu/ICE-BA/blob/b004bb5afc0d554d49742aae8503d231213f7e6d/Backend/IBA/IBA_config.h#L42 to define Marco 'CFG_DEBUG'. Then GBA will be closed.

We provide function to evaluate LBA or GBA time consuming. For back-end only mode, set 'history_lba' or 'history_gba' to '1' in config file, then https://github.com/baidu/ICE-BA/blob/b004bb5afc0d554d49742aae8503d231213f7e6d/App/run_backend.cpp#L431-L436 will print the average time consuming on your terminal. If you want to do this in ice-ba mode, call GetTimeLBA or GetTimeGBA as run_backend.cpp has done.
@wangjio One more question. I got the time of LBA as you suggested, but it took 10+ ms on average, which is much longer than 2-3 ms as shown in the paper. I was running on my laptop with i7-6700HQ 2.6GHz CPU. I understand it is slower than the machine used in the paper but I did not expect such a big difference. Did I do something wrong or the configuration here is different from the paper? Thank you.
