preprocess and filter the data of a single participant
this function preprocesses the data of a single participant. is is written in specific for the SonEMS study participants. the following steps are executed:
- load the VICON data
- load the Zurich Move data
- load the gait summary data
- create ground truth positions from the VICON data, i.e. estimate the position of the JUMP sensor based on the VICON markers
- determine the walking axes
- determine the walking speed
- accumulate the distance based on the walking speed
- align the IMU data with the VICON data
- find the yaw of the IMU data
- filter the data
- Parameters
-
| basepath | (string) the basepath of the data, e.g. "D:/ETH_Data/" |
| ptp | (string) the participant to process, e.g. "SonE_01" |
| options | the options for the processing:
- GT_POS: (logical) create ground truth positions from the VICON data
- FIND_WALKING_AXES: (logical) determine the walking axes
- FIND_WALKING_SPEED: (logical) determine the walking speed
- ACCUMULATE_DIST: (logical) accumulate the distance based on the walking speed
- ALIGN_IMU_VICON: (logical) align the IMU data with the VICON data
- FIND_YAW: (logical) find the yaw of the IMU data
- FILTER: (logical) filter the data
- ekf_tuning_file: (string) the file with the tuning parameters for the EKF, see EKF1::importTuning()

- Note
- the tasks to do which can be set in the options are used to ensure that a task is redone, even if it has been done before, e.g. if filter parameters were changed. if a task is not done yet, it will be executed regardless of the options.
