2. Simply change https://github.com/baidu/boteye/blob/master/scripts/record.sh#L32 to the path where app_tracking is (either the pre-built binary or the one you build locally).

@hgpvision The IMU is polled at ~100 Hz at this moment. See https://github.com/baidu/boteye_driver/blob/1ac52f56ff54d3b83e3606b395f62757b1b40d5c/src/XP_sensor_driver.cc#L288. On the firmware side, the Cypress polls IMU through I2C at 500 Hz (fixed) and timestamps it....

Change the sleep time here. https://github.com/baidu/boteye_driver/blob/master/src/XP_sensor_driver.cc#L320

Unfortunately, there's no easy way to adjust the frame rate at this moment. You need to go into the firmware, modify it, and then flash the firmware into the device...

No. We're still working on providing driver API to adjust image framerate & IMU rate. For now, the only way is to change the firmware and re-flash.

Part of our SLAM engine: http://openaccess.thecvf.com/content_cvpr_2018/papers/Liu_ICE-BA_Incremental_Consistent_CVPR_2018_paper.pdf boteye SDK does more than just SLAM though.

Please follow the instructions here as we try to make things easier with scripts. https://ai.baidu.com/docs#/Roboticvision_Sample-Program/top

No worry. `guide_receiver` still works.

Please provide us with all the "commands" you've used.

After step 4, what's inside `~/mapRecord/navigation`? ```bash ./bin/trajectory_maker --navigation_folder=/home/king/mapRecord/navigation . # this line is correct ``` What's the error message? The files generated in Step 4 (pre_navigation.py) seem missing.
