Real gait/kinematic measures from an OpenPose recording (via PhysioMoCap)

Reads the COCO-18 OpenPose JSON frames, builds a PhysioExperiment, runs [PhysioMoCap::poseFix], and derives real knee-kinematic measures for one side.

Usage

mocap_gait_measures(openpose_dir, side = c("R", "L"), fps = 30)

Arguments

openpose_dir

directory of `openpose_data<N>.json` frames (COCO-18 flat).

side

"R" or "L".

fps

frame rate (Hz).

Value

a list of real measures: knee_rom (deg), knee_smoothness_fixed and _raw (mean |2nd diff| of the knee angle, after / before poseFix), frames, flagged_fraction, leg_swaps.
