    To get the ArduCAM image so that it would be the same orientation that
would work in the case they provided (i.e., camera cable out top of case,
power to right - looking from front).

cv2.imshow("preview_amplitude", amplitude_buf.astype(np.uint8))
cv2.imshow("preview_amplitude", cv2.flip(amplitude_buf.astype(np.uint8),0))

result_image = process_frame(depth_buf,amplitude_buf)
result_image = cv2.flip(process_frame(depth_buf,amplitude_buf), 0)

These 2 changes are in addition to the correction you found.
