Basic 3D Visualisation For this first 3D point clouds plotting experience, we will get our hands-on one essential library: Matplotlib. First, we will add packages in the import section of the initial script, to allow us to use them: 1 import numpy as np 2 import matplotlib.pyplot as plt 3 from mpl_toolkits import mplot3d

established and converted into a 3D point. * Before doing triangulation in the following steps, we calculate the new projection matrix based on the initial projection matrix from the new fundamental matrix. 3.3.2.1 Point adjustment If correspondences fall into category 1, we will re-estimate the 3D point using the new projection matrix.

3D Plotting Introduction 3D plotting is very similar to 2D plotting. The main di erence is that a set of 3D axes must be created within the gure object. A 3D axes object is created using the additional keyword argument projection= ' 3d ' , as shown below. Note that the Axes3D submodule must rst be imported in order to create the 3D axis.

%matplotlib inline Introduction Matplotlib is an excellent 2D and 3D graphics library for generating scientific figures. Some of the many advantages of this library include: Easy to get started Support for formatted labels and texts Great control of every element in a figure, including figure size and DPI.
HOW TO DRAW 3D CHARTS WITH MATPLOTLIB
We first set out canvas to 3D. And this method gives us access to the axes object: from mpl_toolkits.mplot3d import Axes3D ax = fig.gca(projection='3d') Here we will set z, written as zs, to 0. So, this is the plot of (x,y,0). zdir means which direction to 3D. The default size might otherwise be too small. Then we can use the plot() method:

the python-matplotlib package or by running pip install matplotlib. If this is not possible (e.g. you do not have sudo privileges on the machine you are using), then you can install from source using the --user option: python setup.py install --user. Typically, this will install matplotlib into ~/.local. Debian/Ubuntu
