rotation-plots3d 0.0.1

A package to process x, y, z, roll, pitch, yaw data.

rotation-plots3d

A package written in Python 3.12 to assist with generating 3D plots and statistical analysis of time series X, Y, Z, roll, pitch, yaw data.

Description

This package contains methods to generate 3D plots of x, y, z, roll, pitch, yaw data and analyze for repeatability of measurements using a gage repeatability method. It will also generate a stats dataframe for the x, y, z, roll, pitch, yaw and x-prime, y-prime, and z-prime axes.

Installation

To install this python package locally, please use:
pip install rotation-plots3d

Basic Usage

The following examples provide a high-level summary of how to use the API.

Instantitating the OTA Class

Create the ObjectTrackingAnimation class and run the format_raw_data() method.

from rotation_plots3d import ObjectTrackingAnimation

ota = ObjectTrackingAnimation(input_path='files', graph_title="My Creative Title")

Load Data and Create a Graph

ota.load() # loads data into the class as an attribute
ota.create_graph('example.csv','1')
# will generate a plot of the example.csv file located in the output_path directory.

Run Statistics on Data

import os

files = os.listdir('files')

# create a list of every output file repeated by the number
# of dataranges per file. In this case 8x.
filenames = []
for file in files:
    filenames += 8 * [file]

# indicate which device to track for each file. In this case, it is
# device "1" for every file.
device = ['1'] * len(filenames)

# for each file, create a list of start and stop time ranges
datarange = [[0,3],[3,6],[6,9],[9,12],[145,150],[150,155],[155,160],[160,165]]

# create the stats dataframe
df = ota.stats_dataframe(filename=filenames,device=device,datarange=datarange)

print(df)
