Create a Calibration object based on a dataframe which has all required sections labeled.
The expected Dataframe has the section label as index and has at least the 6 required data columns. The index must contain all the sections listed in
FerrarisCalibration`
.FERRARIS_SECTIONS`.- Parameters:
- df
6 column dataframe (3 acc, 3 gyro)
- acc_cols
The name of the 3 acceleration columns in order x,y,z.
- gyr_cols
The name of the 3 acceleration columns in order x,y,z.
- Returns:
- ferraris_cal_objFerrarisSignalRegions
Examples
>>> import pandas as pd >>> sampling_rate = 100 #Hz >>> df = ... # A valid DataFrame with all sections in the index >>> print(df) acc_x acc_y acc_z gyr_x gyr_y gyr_z part x_a -2052.0 -28.0 -73.0 1.0 0.0 -5.0 x_a -2059.0 -29.0 -77.0 2.0 -3.0 -5.0 x_a -2054.0 -25.0 -71.0 3.0 -2.0 -3.0 ... ... ... ... ... ... ... z_rot -36.0 35.0 2079.0 2.0 -5.0 -2.0 z_rot -28.0 36.0 2092.0 6.0 -5.0 -4.0 z_rot -36.0 21.0 2085.0 5.0 -4.0 -4.0 >>> regions = ferraris_regions_from_df(df) >>> regions FerrarisSignalRegions(x_a=array([...]), ..., z_rot=array([...]))
