I am using Processing 3.3.6 with the openkinect library (link below). I have a Kinect V2 sensor, and as given in the examples in the below link, I am getting the depth values from a depth[] array.
Openkinect Library for Processing
The link above gives the formula given for converting the raw depth value to depth value in meters in real world.
depthInMeters = 1.0 / (rawDepth * -0.0030711016 + 3.3309495161);
This is adapted from here :Depth in meters calculation
I am getting values ranging from 0 - 4500, and after applying the formulae from the above references, the values after conversion to meters are not accurate, they are off by about 70m. So, is there any other way or method to convert the depth to meters. Should I only use the official development environment like Visual Studio (C++ , C#) with the SDK for calculating depth?
Or can open source tools like Processing be used to capture the values albeit with a different approach? Help or guidance would be appreciated as it is a completely new area for me so far.
