Why the depth data is 424*512*4?

Hello! Thank you for sharing. Why the depth data is 4245124? What does the depth data of every dim mean?

Well because you will get R, G, B and Depth channels.

I am also having issues with the depth data returned by getDepthData(). The fourth channel value is always 69, no matter how far away the object is.

This repo is said to be python bindngs to libfreenect2, but when I go into libfreenect2 and run ./bin/Protonect, the depth image looks nothing like the depth image from this library. In libfreenect2, every distance is given a homogeneous gray value, that changes uniformly with distance. This depth image gives varying pixel colors for a single object, meaning a flat wall looks green and purple.

The depth image also doesn't cover the same field of view as the color image, and I am wondering how to match up depths of pixels in the color image.

I am running this with python 2.7.6 on ubuntu 14.04.
