OpenCV + Python build (2/2) - vs code setting

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 side 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()
