Hello, What is the best way to calculate the equation of the floor plane in a scene?

[RTang10]

So that I can measure the the distance normal to the plane to a point which would be height.

At the moment I am taking 3 points by clicking positions in the image and taking the world coordinates and calculating the equation of a plane.

 However this is very unreliable and inaccurate, is there something I am missing?

Hello RTang10, Thank you for your interest in the Intel RealSense Technology. You can check out the opencv example DNN - https://github.com/IntelRealSense/librealsense/tree/master/wrappers/opencv/dnn This example will calculate approximate distance to an object using the depth data. Thank you and best regards, Eliza

Hello Eliza, thank you so much for your help,

The link provided was a little bit useful however I managed to find another solution to the problem by using the difference of y coordinates to get the height.
