cvlecture :

Install Python & OpenCV (1/2)

Install IDE and test OpenCV (2/2)

 

 

1. Install Python

Window & Mac

Download Python installer file : https://www.python.org/downloads/release/python-373/

 

  • download python installer

 

  • run installer and check Path

 

  • Make sure where python will be installed

 

  • check python version

 

  • pip upgrade

>pip install --upgrade pip

Refer to other person tutorial : https://www.ics.uci.edu/~pattis/common/handouts/pythoneclipsejava/python.html

 

 

2. Install Python OpenCV

  • opencv-python installation

>pip install opencv-contrib-python

 

  • check OpenCV version

 

 

3. Install IDE

Download Visual Studio Code

https://code.visualstudio.com/Download

 

install

 

 

 

run VS code -> Set python interpreter -> run simple code

Find python in "extensions:marketplace" and install

 

type in command window "python: select interpreter"

 

select python execute which we have installed before

 

run code

 

 

4. Test OpenCV

Simple OpenCV Code : https://gist.github.com/MareArts/9034e7e638a30551d9ef370c4a364618

import numpy as np
import cv2

cap = cv2.VideoCapture(0)
ret, frame = cap.read()

while(True):
 # Capture frame-by-frame
    ret, frame = cap.read()
 
 # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

 # Display the resulting frame
    cv2.imshow('frame',gray)
 if cv2.waitKey(1) & 0xFF == ord('q'):
 break

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

 

 

 

Thank you! ☕️
