Depth in meters for rendered images How can I get the depth in meters? I need the "real" distance from the camera to each pixel.

As the next picture but each pixel values representing the distance in meters to the camera.



I am creating my first project with Blender, which builds an animation to obtain rendered images from different viewpoints. I am setting several values for the camera location using python scripts and using the Depth option (Z pass) in Render Layers Node.

I already read many answers about it, but I still don't understand how to set correctly the camera intrinsic parameters for real depth.



Something is wrong, I need this pixel value closed to 7m, or depending on the camera distance, but I am obtaining the next results.

Actual depth result with a normalization node:


Actual depth result without normalization:
The Z pass is the absolute distance from the camera to objects in the scene for every given pixel on the image. The camera is the 0 on the scale and the units used for its values are the working units set for the scene (blender units, meters, cm, inches, etc).



The minimum and maximum values are clipped according to the camera's start and end clip distances.
