Python imread Examples

Example #1

def photo_loop():
    for fname in os.listdir('chessboard'):
        if fname[0] == '.': continue
        frame = cv2.imread('chessboard/' + fname)
        frame = cv2.resize(frame, IMAGE_SIZE)
        # frame = cv2.undistort(frame, mtx, dist, None, newcameramtx)
        frame = cv2.warpPerspective(frame, perspective_matrix, IMAGE_SIZE)
        cv2.imshow('image', frame)
        cv2.waitKey(0)

Example #2

def photo_demo():
    # Capture frame-by-frame
    frame = cv2.imread("images/camera-view.png")
    frame = cv2.resize(frame, IMAGE_SIZE)
    show(frame, 'image')
    # frame = cv2.undistort(frame, mtx, dist, None, newcameramtx)
    frame = cv2.warpPerspective(frame, perspective_matrix, IMAGE_SIZE)
    frame = cv2.flip(frame, 1)
    frame = cv2.flip(frame, -1)
    show(frame, 'transformed')

    frame, output = process_image(frame)

    global IMAGE
    IMAGE = frame
    global OUTPUT
    OUTPUT = output
    if SHOW_SINGLE_CAPTURE_AND_DUMP:
        cv2.imshow('label', frame)
        cv2.waitKey(0)

    # cap.release()
    cv2.destroyAllWindows()
