    Hi,
    

    What I am trying to do is to obtain a valid depth map from AD-3DSMARTCAM1-PRZ that can later be processed by OpenCV.
    

    So I .run the first-frame.py and found that after the following line:
    

    image = np.array(frame.getData(tof.FrameDataType.Depth), dtype="uint16", copy=False)
    

    the shape of image is (1560, 2560). So my question is what's the proper pre-processing for such image?
    

    

    I also tried to follow the pre-processing steps in the dnn.py:
    

    new_shape = (int(depth_map.shape[0] / 2), depth_map.shape[1])
depth_map = np.resize(depth_map, new_shape)
depth_map = cv.flip(depth_map, 1)
distance_map = depth_map
depth_map = distance_scale * depth_map
depth_map = np.uint8(depth_map)
depth_map = cv.applyColorMap(depth_map, cv.COLORMAP_RAINBOW)
    

    However, it is still not a proper depth map from the result of cv.imshow().
    

    I would be very grateful if anyone can help with this.
