Big thanks!

Hello,

I just wanted to say a big **thank you** for your code! It helped me a lot to add distance sensor to my robot.

I noticed that I usually don't need the "calibration" step as the measurements are very reliable at close range.
You can have a look at what I have [here](https://github.com/Kylir/opencv-playground/blob/master/src/tof-utils.js) (still in progress!)

Again: thanks!
