How to detect rectangles in OpenCV Python?

Find the approximate contour for each of the contours. If the number of vertex points in the approximate contour is 4 then we compute the aspect ratio to make a difference between the rectangle and square. If the aspect ratio is between 0.9 and 1.1 we say it is a square else a rectangle See the below pseudocode.

What is rectangle OpenCV?

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2. rectangle() method is used to draw a rectangle on any image.

Can OpenCV detect objects?

OpenCV is the huge open-source library for computer vision, machine learning, and image processing and now it plays a major role in real-time operation which is very important in today's systems. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human.
