What does cv2 waitKey return?
cv2. waitkey(1) waits for 1 ms and returns the code of the key on keyboard if it is pressed.
Why do we use cv2 waitKey?
waitkey() function of Python OpenCV allows users to display a window for given milliseconds or until any key is pressed. It takes time in milliseconds as a parameter and waits for the given time to destroy the window, if 0 is passed in the argument it waits till any key is pressed.
How do I increase FPS in OpenCV?
The “secret” to obtaining higher FPS when processing video streams with OpenCV is to move the I/O (i.e., the reading of frames from the camera sensor) to a separate thread. You see, accessing your webcam/USB camera using the cv2. VideoCapture function and the . read() method is a blocking operation.
What does cv2 waitKey 1 mean?
cv2. waitkey(1) is being used in while loop.It shows the output for 1msec but because of infinite while loop it is the sequence of images that are perceived by our brain as a single continuos video.
What is frame rate in OpenCV?
The reason for it is that this camera supports 4K@30fps, but the customer can access only 10fps in 4K resolution while using the default OpenCV Python SDK. In reality, customers need a higher resolution with a minimum of 30fps for their applications to ensure effective image processing capabilities.
