How to find the disparity map values in python using RealSense D435 ?

[JJivr]

Basically how to obtain the distance of object from camera using Real Sense D435 in python?

[MartyG]

An option for achieving this may be to use your RealSense D435 camera with Python and the OpenCV vision software.

How to configure real sense D435 with OpenCV ?

The RealSense SDK's documentation has some guidance about getting started with OpenCV on Windows or Linux.

https://github.com/IntelRealSense/librealsense/tree/master/wrappers/opencv#getting-started

It also has another guide for an initial OpenCV program to test the setup with.

Please provide me the guide for an initial OpenCV program to test the setup in python.

The RealSense SDK's Python wrapper has an example of a simple OpenCV viewer program.
