OpenCV 4 with Python Blueprints - Second Edition

Understanding the main routine function

Our main routine function will consist of creating and interacting with an instance of the SceneReconstruction3D class. This code can be found in the chapter4.py file. The dependencies of the module are numpy and the class itself, which are imported as follows:

import numpy as np 
 
from scene3D import SceneReconstruction3D

Next, we define the main function:

def main():

The function consists of the following steps:

1. We define the intrinsic camera matrix for the camera that took photos of the fountain dataset (K) and set distortion coefficients (d):

K = np.array([[2759.48 / 4, 0, 1520.69 / 4, 0, 2764.16 / 4,               1006.81 / 4, 0, 0, 1]]).reshape(3, 3)d = np.array([0.0, 0.0, 0.0, 0.0, 0.0]).reshape(1, 5)
