Apply Calibration

Description

Apply Calibration

Usage

apply_calibration(sensor_data, cal_params, measurement_device, use_temp = TRUE)

Arguments

sensor_data	Raw sensor-level data from a bin file in the form (x, y, z, light, button, temp).
cal_params	Calibration parameters for acceleration and light from MPI.
measurement_device	Name of the measurement device used "GENEActiv 1.1" or "GENEActiv 1.2".
use_temp	Allows auto-calibration to be run with and without temperature compensation.

Details

Function to apply calibration to sensor-level data from a bin file.

Value

Data frame of calibrated sensor data.
