Research software for navigating a UAV in indoor environments
Project description
A Python package for simulating UAV Navigation in Satellite-Less Environments. The package contains two algorithms the GTRS [1] and WLS [2] whose goal is to estimate and navigate a UAV.
Installation
Install from PyPI:
pip install --upgrade pip
pip install autonav
First Steps
After installing the package one can import the algorithms and necessary dependencies as follows:
from autonav import gtrs, wls
from autonav.file_handlers import readpathfile
from autonav.plots import plot_trajectories
from numpy import array
Afterwards, one can create the necessary values to run the algorithms:
b = 200
n = 8
a_i = array(
[
[0, 0, 0],
[0, b, 0],
[b / 2, 0, 0],
[b / 2, b, 0],
[0, 0, b / 8],
[0, b, b / 8],
[b / 2, 0, b / 8],
[b / 2, b, b / 8],]
).T
k = 50
sigma = 1
initial_uav_position = [10, 10, 5]
destinations = readpathfile("tests/path_files/Path.txt")
Finally, call the GTRS or WLS algorithm and plot the trajectories:
[estimated_trajectory, true_trajectory] = gtrs(a_i, n, k, sigma, destinations, initial_uav_position)
plot_trajectories(destinations, estimated_trajectory, a_i)
