OpenMV code How to use?

[mano1979]

I am looking at your python code for the Openmv cam. though I am not clear how to extract values for navigating. I used RoboRealm before which had this kind had this kind of plugin (called floor finder), and it exported the value for the highest point in the image that had a clear floor aka no obstacles. it also had the option to set a specific space to which the script was looking for clear floor. So you could only look in the middle of the screen and not on the edges

see here: http://www.roborealm.com/help/Floor_Finder.php

anyway i'd like to know how and what values to print over serial to see these values.
