how to read a frame map by frame

[yzf123456]

Hello,
I have already installed pylibfreenect2, and can open kinect 2 in Python. I want to read image information frame by frame, but I don't know how to write the code?Someone has relevant source code, I am very grateful.

pylibfreenect2/examples/multiframe_listener.py

Lines 61 to 92 in 4bea7cb

	while True:
	frames = listener.waitForNewFrame()
	color = frames["color"]
	ir = frames["ir"]
	depth = frames["depth"]
	registration.apply(color, depth, undistorted, registered,
	bigdepth=bigdepth,
	color_depth_map=color_depth_map)
	# NOTE for visualization:
	# cv2.imshow without OpenGL backend seems to be quite slow to draw all
	# things below. Try commenting out some imshow if you don't have a fast
	# visualization backend.
	cv2.imshow("ir", ir.asarray() / 65535.)
	cv2.imshow("depth", depth.asarray() / 4500.)
	cv2.imshow("color", cv2.resize(color.asarray(),
	(int(1920 / 3), int(1080 / 3))))
	cv2.imshow("registered", registered.asarray(np.uint8))
	if need_bigdepth:
	cv2.imshow("bigdepth", cv2.resize(bigdepth.asarray(np.float32),
	(int(1920 / 3), int(1082 / 3))))
	if need_color_depth_map:
	cv2.imshow("color_depth_map", color_depth_map.reshape(424, 512))
	listener.release(frames)
	key = cv2.waitKey(delay=1)
	if key == ord('q'):
	break
