Can nodern smartphone cameras generate 'Z - depth' images?
show user profile  Boing
I know some top end smart phones are equipped with dual cameras to let you generate a manually adjustable depth of field effect. I assume they do this the same way anyone does by generating some kind of alpha channel to capture depth info, does anyone know if it's possible to extract this? In other words if I was to photograph a stone wall for a texture would it be able to generate it's own displacement map?

if you had a light field camera, probably.

This looks like it's going to be interesting:

with a pair of single camera's, then yes... technically you can create a depth based map.


but...


the fidelity (in a multitude of dick measuring capacities) would be seriously limited.

for what you're talking about, lasers are a much better choice for accurate digital reproduction...

I think Project tango seems to be more about mapping environmental geometry, it's interesting but not really applicable to capturing textures.

As for using field cameras or mounting dual cameras into a custom rig, that's maybe technically possible but probably more effort than just making a map manually.

What I was talking about was trying to use the systems already available in something like the HTC One or Galaxy S5 where they have a secondary camera built in to capture depth information. You can then take a picture and manually add depth of field the same way we would to a render.

What I wasn't sure about was the fidelity of the second camera, there's a big difference between capturing depth info across a 100m scene and across a stone wall with 30mm of depth.

why do you think that sort of stuff is well paid for by production budgets? it's not easy...

I know, that's why I'm looking for an easier way of doing it!
