Gig-E is a communication standard for a wide range of cameras. OpenCV now contains a wrapper for The Prosilica Gig-E based cameras (see CV_CAP_PVAPI) But in general it’s better to use the camera’s native API to get the data and then use openCV to convert the returned data into an image, openCv contains a number … Read more
Perhaps the following illustration showing the relationship between the various spaces will help: Depending if you’re using the fixed-function pipeline (you are if you call glMatrixMode(), for example), or using shaders, the operations are identical – it’s just a matter of whether you code them directly in a shader, or the OpenGL pipeline aids in … Read more
I think the solution mentioned in the question, namely having a separate thread that clears the buffer, is the easiest non-brittle solution for this. Here reasonably nice (I think) code for this: import cv2, queue, threading, time # bufferless VideoCapture class VideoCapture: def __init__(self, name): self.cap = cv2.VideoCapture(name) self.q = queue.Queue() t = threading.Thread(target=self._reader) t.daemon … Read more
