get distance from the depth map for Android Phones #125

Hi @ranftlr

Thanks for the wonderful work.

In the context of getting the absolute depth map, I followed these issues 42 25, 4

From this, I understood that in order to get the absolute depth maps, we need to know the absolute depth of at least two pixels in the image.

if I have an Android app:

that captures the photo. Infer through MiDas tflite model generate depth map

So as we don't know the distances of the two pixels in images ( no ground truth image.) we can't get the absolute depth map.

So how to deal with this situation?

We currently don't know a good way to recover absolute depth without external measurements.
