Restoring a 3D point from two observations through triangulation

In this recipe, you will learn how to reconstruct 3D point coordinates given observations in two views. This is a building block for many higher level 3D reconstruction algorithms and SLAM systems.

Getting ready

Before you proceed with this recipe, you need to install the OpenCV version 3.3 (or greater) Python API package.

How to do it

You need to complete the following steps:

1. Import the necessary modules.

import cv2
import numpy as np

2. Generate the test camera's projection matrices:

P1 = np.eye(3...
