How to use opencv in pycharm

The steps to use OpenCV in PyCharm are as follows: install OpenCV and its Python bindings; import OpenCV in the Python script; use cv2.imread() to read the image; use cv2.imshow() to display the image; use Other OpenCV functions perform image processing and computer vision tasks.

Using OpenCV in PyCharm

Step 1: Install OpenCV

• Go to the OpenCV official website (https://opencv.org/) to download the version suitable for your operating system.
• Install according to your system installation instructions.

Step 2: Install the OpenCV Python bindings

• Open PyCharm and create a new Python project.
• Go to "File" > "Settings" > "Project" > "Project Interpreter".
• Click the " " button and search for "opencv-python".
• Install the package and restart PyCharm.

Step 3: Import OpenCV

• In your Python script, use the following code to import OpenCV:

import cv2

Step 4: Read the image

• Use the cv2.imread() function to read the image:

image = cv2.imread("image.jpg")

Step 5: Display the image

• Use the cv2.imshow() function to display the image:

cv2.imshow("Image", image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Others Tip

• Use the cv2.cvtColor() function to convert the image color space.
• Use the cv2.resize() function to resize the image.
• Use cv2.Canny() function edge detection.
• Use cv2.HoughLines() function Hough line detection.

By following these steps, you can easily use OpenCV in PyCharm for image processing and computer vision tasks.
