I have an object ( an example is people), I’m scanner object and how to get the height of object?
That really depends on which application you are using.
My suggestion, which will work for many apps, is to export the files created by the scanner and the Structure Sensor onto a computer where you can import those files into a 3D graphics program capable of making measurements.
What @anthony.monaco said, or if you need to implement in your program, search for papers on principal component analysis.
thank @anthony.monaco, but I want to implement it in my code, I want to get the height of an object but I don’t know to do that in my code
