calculate distance using disparity map

D:= Distance of point in real world,
b:= base offset, (the distance *between* your cameras)
f:= focal length of camera, 
d:= disparity:

D = b*f/d

it works but i'm getting the result in an matrix?!! is that ok?

oh, hehe. yes that's ok.

if you went and divided b*d ( a number ) by your disparity matrix, python will make a matrix as result.

every cell now contains the resp. distance at that point

yopiii :) , thank you sooooo much

can you give me the code for calculating distance using disparity?

@apoorva it's right in front of you ?

How come pixel size isn't included in the formula?

Or is the pixel size implicitly included if we state disparity in the same measurment unit as focal length?
