GENEAcore (version 1.1.2)

apply_calibration: Apply Calibration

Description

Apply Calibration

Usage

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

Value

Data frame of calibrated sensor data.

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.
